Blood

Blood is a bodily fluid consisting of plasma, blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. In many species, it also carries hormones and disease-fighting substances. In this category, you will find questions about the blood in your body, including blood types, blood diseases, and the function of blood.

Which type of blood vessels (artery or vein) has valves?

Veins. The inner layer of veins (the tunica intima or tunic interna) forms valves to reduce backflow because. Veins have lower blood pressure than arteries and are often fighting against gravity, so the prevention of backflow is essential.

Whats wrong if it burns when you urinate an theres blood in your urine?

you need to see a doctor you might have a bladder infection or a urinary tract infection...good luck eh Depending on your gender, it can mean a couple of different things, but most likely you have a bladder infection or an STD from the venerial disease family. Go see a doctor as soon as you can for diagnosis and treatment. Most things that cause burning during urination aren't life threatening, but can become worse and can cause other problems, like infertility, or can leave you vulnerable to other diseases (some think that it's easier to catch other STDs if you already have one.) Make an appointment today.
Often, if you are experiencing pain/burning while urinating this is due to a change in the pH level of the urine. This can be caused by diet, but may also denote the presence of infection.

If infection is present, it could be a simple UTI (urinary tract infection), but it may be something more serious, such as a bladder or kidney infection, or possibly even an STD (sexually transmitted disease). It is always best to see your physician in order to have a simple test done, because prescriptions may be all that is required to clear the problem up.

Are the red blood cells produced in the liver?

Liver contains lots of iron. Your body needs iron to produce red blood cells. If you don't like liver, you can get iron from spinach.

What is the normal white blood cell count reading?

Hello

Blood test results, made possible by the taking of Blood tests, are one of the most important tools that your doctor uses in evaluating your health status. It is important to realize that your Blood test result may be outside of what is called the 'normal range' for many reasons. Blood tests, including various Blood chemistry and hematology 'Blood tests' offered by most test labs, represent an economical way by which quality information about a patient's physical condition, at the time of the Blood testing, can be made available to the physician. These Blood test results, after review and interpretation by a qualified Blood professional, play an important part in an overall diagnosis. Blood test results are important in Blood disorders in Blood tests and a Blood test with Rare Blood types. Blood test results are compared and measured in 'normal ranges' for a given population group. Low cost Blood tests, discount Blood testing and even free Blood tests are available and listed in your local community.

SEE HIV HOME BLOOD TEST KIT INFORMATION - TEST FOR HIV/AIDS AT HOME Because most Blood test reference ranges (often referred to as 'normal' ranges of Blood test results) are typically defined as the range of values of the median 95% of the healthy population, it is unlikely that a given Blood sample, even from a healthy patient, will show "normal" values for every Blood test taken. Therefore, caution should be exercised to prevent overreaction to mild abnormalities without the interpretation of those tests by your examining physician. Again, a Blood test, though important, is only a part of the final diagnosis of a health problem. Often, you can get your Blood tested at the Bloodmobile. Physicians rely on "Blood-work," or clinical laboratory diagnostic Blood testing to diagnose medical conditions. From this Blood testing the medical professional then prescribes therapies and remedies, based on those Blood tests.

Screening Blood tests are used to try to detect a disease when there is little or no evidence that a person has a suspected disease. For example, measuring cholesterol levels helps to identify one of the risks of heart disease. These screening tests are performed on people who may show no symptoms of heart disease, as a tool for the physician to detect a potentially harmful and evolving condition. In order for screening tests to be the most useful they must be readily available, accurate, inexpensive, pose little risk, and cause little discomfort to the patient.

Diagnostic Blood tests are utilized when a specific disease is suspected to verify the presence and the severity of that disease, including allergies, HIV, AIDS, Hepatitis, cancer, etc. What is a Blood test? Blood tests are an essential diagnostic tool. Blood is made up of different kinds of cells and contains other compounds, including various salts and certain proteins. Blood tests reveal details about these Blood cells and, Blood compounds, salts and proteins The liquid portion of the tested Blood is plasma. When our Blood clots outside the body, the Blood cells and some of the proteins in Blood turn into a solid. The remaining liquid is called serum, which can be used in chemical tests and in other Blood tests to find out how the immune system fights diseases. Doctors take Blood samples and grow the organisms, found in Blood tests, that cause illness, to evaluate each, microscopically.

How is a Blood test carried performed? Blood samples taken for Blood testing can be taken either from a vein or from an artery. A few drops of Blood are needed, most of the time. It is often enough to take a small drop from the tip of your finger and then squeeze the Blood out for Blood testing. Most Blood tests are taken from a vein (veins carry Blood FROM the heart,) most often from those veins near the elbow. First a tourniquet is tied around the upper arm to make the vein easy to find and take the Blood for the Blood test. The place where the injection is to take place is then made sterile and then a hollow needle is put into the vein. The needle will be attached either to a Blood test sample bottle or to a syringe where the plunger is pulled back to create low negative pressure. When the needed amount of Blood for testing has been removed from the vein, the needle is removed. The area is then re-cleaned and pressure is placed on the area with a small ball of cotton. This is pressed against the area for a couple of minutes before applying a bandage. Blood test results are important in Blood disorders in Blood tests and a Blood test with Rare Blood types. Blood tests are relatively painless. Platelet testingis a Blood test that is often used by doctors. First lets define platelets. Platelets are very small cells in the Blood. These clump together at places where injury to Blood vessels occur. They are the basis of the Blood clot that normally forms when the skin is broken. A Blood test revealing a low platelet count can make us vulnerable to bleeding, sometimes even without an injury that we see. Some of the causes of a low Blood platelet count include autoimmune diseases, where the effected individual produces an antibody to his or her own platelets, chemotherapy, leukemia, viral infections and some medicines. High numbers of platelets make an individual more vulnerable to Blood clotting. High Blood platelet counts are always found where a condition involving bone marrow such as leukemia, cancer and other Blood borne conditions that are revealed by Blood test results. Pharmacy shelves are stocked with do-it-yourself home tests for Blood glucose, Blood cholesterol paternity tests and pregnancy tests. OraSure Technologies Inc., makes and sells a 20-minute, at-home test that screens for two HIV strains using a swab device that tests saliva. No Blood test is completely accurate all of the time. Sometimes a test result is incorrectly abnormal in a person who does not have the suspected disease (a false-positive result). Sometimes a test result is incorrectly normal in a person who has the disease (a false-negative result). Tests are rated in terms of their sensitivity (the probability that their Blood testing results will be positive when a disease is present) and their specificity (the probability that their test results will be negative when a disease is not present). A very sensitive test is unlikely to miss the disease in people who have it, however, it may falsely indicate disease in healthy people. Blood test results are important in Blood disorders in Blood tests and a Blood test with Rare Blood types. A very specific test is unlikely to indicate disease in healthy people. Although, it may miss the disease in some who have it. Problems with sensitivity and specificity can be largely overcome by using several different Blood tests. Because your physician can not always be sure whether or not the reported result of a particular test from a particular person is false or true, a person with an abnormal result may often need to be re-tested or undergo a different type of testing.

Normal test result values are expressed as a reference range, which is based on the average values in a healthy population; 95% of healthy people have values within this range. These values vary somewhat among laboratories, due to methodology and even geography. Blood tests and Blood testing methods and quality vary widely in different parts of the world and in different parts of many countries, due to characteristics in the population, both racial Blood differences and ethnic Blood characteristics, among other factors. Free Cord Blood testing at the Bloodmobile. American Blood laboratories use a different version of the metric system than does most of the rest of the world, which uses the Systeme Internationale (SI). In some cases translation between the two systems is easy, but the difference between the two is most pronounced in the measurement of chemical concentration. The American system generally uses mass per unit volume, while SI uses moles per unit volume. Since mass per mole varies with the molecular weight of the substance being analyzed, conversion between American and SI units requires many different conversion factors. Keep in mind that there are three Blood test "normal ranges." Normal Range Results

The results of virtually all Blood tests ordered in North America are compared to "normal ranges" as provided on a "Lab Results Report." If your tests indicate that you are within the normal range, you are most often considered normal. A "normal" Blood test result does not necessarily mean that you are healthy. The problem with these lies in how "normal ranges" are determined at that particular Blood testing laboratory.

Population Best/Optimum Ranges

In our opinion, every Blood test result must be compared to Blood test result scores other than the accepted lab "norms." Your potential statistical best possible Blood test ranges must be considered. These Blood test range "best" results should interpreted considering your physiology and unique biochemistry such as your height your weight, age, gender, health history since childhood. Further, the inter-relationship with your other blood test scores must be considered. One imbalance often causes another. Blood test range scores outside your unique Blood test range results can be affected by sleep, diet, exercise, medicines, and vitamin supplements.

Your Personal Norms

Your Blood test score, chronicled over time, will vary by few points, one way or the other. These Blood test results, considering sleep, diet, exercise, medicines, and vitamin supplements, etc. will most certainly vary. Each person on any given day has their own set of Blood test results. Consider your gas mileage in your car. If reviewed over time, each time you fill up and record your gas mileage, it varies. The car is the same, the driver is the same, the gas is the same, but the mileage, from fill-up to fill-up varies. We recommend periodical Personal Blood Testing. Your personal norms must be considered over time. Each individual has his or her own unique personal Blood test normal range, best for you. Remember, if you do not get Blood tests, and if you do not keep track of them, and if you do not have them available to your doctor, You will not know and can not use your normal Blood test range.

Does plasma have platelets in it?

Blood plasma contains platelets, RBC and WBC cells in them. the answer to your question is yes.

plasma is the component of blood obtained after removing all the blood corpuscles like RBC,WBC and platelets

so it doesnt contain platelets

but there are substances called platelet rich plasma where the plasma is enriched with

platelets for specific purposes

Can you cough up blood through smoking weed?

Smoking does not make you cough up blood.

Consult a physician immediately if you begin coughing up blood. Coughing up blood, especially if you have had years of being a smoker, is likely a sign of lung cancer. It also could be a symptom of tuberculosis.

Can mother with B negative blood and father with O positive blood have a baby with AB negative blood type?

We are looking for the possible blood types of a baby.

Parental information:

  • Mother type B neg -- can be BB or BO and only Rh (--)
  • Father type O pos -- can only be OO with Rh (+-) or (--)
Baby recieves one gene from each parent:
  • Baby is type BO Rh (+-) = B pos
  • Baby is type BO Rh (--) = B neg
  • Baby is type OO Rh (+-) = O pos
  • Baby is type OO Rh (--) = O neg
NOTE: There is NO A gene for either parent.

Generally the baby will be either Type B pos/neg or Type O pos/neg.

HOWEVER: There is more to ABO blood typing that just the ABO gene.

There is also an inhibitory gene that will change any genotype into the phenotype O.

Therefore a person with genetically AB blood can be tested as having Type O.

  • A baby from these parents could be AB neg IF
If one Type O parent has the inhibitory gene affecting his AA, AO or AB type, then the baby can be AB negative.

Can old blood period?

There is one pool of blood, so that any sample will have both young and old red blood cells.

The process where blood moves throughout the body?

As blood moves through the body, the concentration of oxygen decreases as the concentration of carbon dioxide increases in the body and the concentration of glucose in the blood also decreased. This is because body cells require glucose and oxygen for respiration/to produce energy, whilst carbon dioxide is a waste product of repiration thus the amount of carbon dioxide will increase. As it moves past/through the intestines, the concentration of glucose, lipids and ions increase as the small intestines reabsorbs food. As blood moves through the kidneys, the concentration of urea drops significantly however the concentration of dissolved ions may differ depending on what the body needs to retain. As blood moves through the liver, amino acids -> ammonia -> urea.
And as it enters the left side of the heart, it has low concentration of oxyden and high concentration of carbon dioxide. As it moves out from the left side of the heart, it is oxygenated and has less concentration of carbon dioxide.

How long does it take to infuse 2 units of blood?

A unit of blood is recommended to be infused over 1.5 to 2 hours. Properly typed and crossed compatible blood can be infused with the same set so 2 units can be given in 3-4 hours give or take 15 mins or so if you have to change the infusion set.

What group of proteins mark foreign invaders and attract phagocytes to destroy them?

B cells release antibodies that attach to foreign invaders and mark them for destruction by phagocytes.

Why should blood not be drawn routinely from above an iv infusion site?

When asking why blood is drawn 'below' an IV site, it is presumed that this means distal (or further from the heart) when compared to the IV. The reason for drawing blood distal to the site of IV insertion is simple. When venous blood returns to the heart, administration of medications, electrolytes, and fluids is often through the IV. Therefore, we want to obtain blood which has not yet been affected by the medication or fluids given to the patient through the IV. For example, if a patient's blood magnesium levels are low, and we are giving therapeutic magnesium to increase these levels, we would want to monitor the effect of our treatment. Therefore, we would want to see the effect of magnesium infusion at a site without interference by the magnesium being infused through the IV. Therefore, we measure distal to the site of the IV, so that our blood sample represents the body's general levels magnesium, without influence from the IV line.

What happens when leukocyte is found more than the normal range?

When the leukocyte count is high, the physician should suspect either an infection or cancer, as these are the two most common reasons for an elevated leukocyte count. Depending upon the rest of the physical examination and the results of the rest of the blood tests, your physician may already know which of the two it is.

Why do I love the taste of my own blood?

I don't have a documented answer. My educated guess is that people, when wounded, want the wound to go away. So they'll pick scabs, rub bruises -- and lick their own blood. Anything to make evidence of the wound disappear. I believe giving the illusion (even if the patient doesn't believe it) of wellness is very therapeutic.

Are platelets cells that fight of disease?

Yes they are one of the main constituent of cytogenic immunity.

How to calculate blood volume by body weight?

Blood volume is typically about 8% of body weight. An average sized adult has a blood volume of about 5 liters.
