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.

A normal Liver count is one. If you have more than one, you might want to check that out...
What does it mean when you pee you wipe and there is a little blood?
It could mean you are about to start your period or you may have a bladder infection. I had this happen before when I had a bladder infection... If you're pregnant it could be the onset of a miscarriage
It is not spread among humans, but it is spread throughout the body by the cells. Leukemia is cancer of the white blood cells. Like other cancers it is not contagious. White blood cells help to fight infections, so obviously a person with Leukemia is unable to fight off infection. However, if caught in time it is one of the more curable cancers.
Blood plasma makes up 55% of the total blood volume. It is 90% water by volume and it contains dissolved proteins, glucose, clotting factors, mineral ions, hormones, and carbon dioxide (since plasma is being the main medium for excretory product transportation).
Well there are two types of blood cells White and Red
Red carries O2 throught your body and takes CO2 wastes away from your body.
White find germs, eat foreing objects in your body and kill infections.
How long does a red blood cell last?
Red blood cells usually live three to four months before they die. They live a short life because they have a hard job to do; to carry oxygen and carbon dioxide, both gases are very corrosive and toxic in high concentrations.

What blood cells bring oxygen to cells?
That would be the Respiratory System. The respiratory system is responsible for the gas exchange in the cells of your body. When you inhale (or breathe in), air passes through your nose, down your windpipe, and into two tubes called the bronchial tubes. These tubes lead into your lungs. The tubes branch many times, like a tree, so that your lungs are filled with tiny tubes. The smallest tubes can only be seen with a very strong microscope. At the ends of these tubes are air sacs. Air is moved from the air sacs into the cells of the body by diffusion. This is the movement of a substance from an area with a lot of that substance to an area with less of the substance. When the oxygen-poor cells arrive in the lungs from the heart, the oxygen moves into the cells. The CO2 (carbon dioxide), on the other hand, is more concentrated in the cells, so it moves out of the cells, and into the air sacs. When you exhale (or breathe out), the CO2 leaves your body by the same path by which the oxygen entered. Breathing is only a part of voluntary movement. Part of the reason that you breathe is involuntary. It is caused by the movement of muscles called the diaphragm. This is a sheet of muscles beneath your lungs. When the diaphragm moves downward, it increases the space around the lungs. When the diaphragm moves up, it decreases the space around your lungs, and the air rushes out.
What is the sequance of events leading to the formation of a blood clot?
The thin, single layer of cells than line a blood vessel is called the endothelium. (The walls of the smallest vessels, the capillaries, are comprised of the endothelium alone.) When the endothelium is intact and healthy, a clot, of course, should not form. A break in the endothelium allows platelets to contact collagen and the other factors that activate platelets. Coagulation reactions begin occurring more rapidly since tissue factor is exposed and the surface of activated platelets provides the environment for the activation of the cascade that ultimately converts prothrombin to thrombin. The developing clot consists of interlaced fibrin fibrils and activated platelets.
In addition to an actual break in the endothelium, various other situations can lead inappropriately to activated platelets. Injury to the endothelium, in general, tends to activate platelets. An important example here is a developing atherosclerotic plaque. Other examples include turbulent blood flow or damage to endothelium from an immunological cause.
Excessive activation of the blood coagulation reactions can results from stasis of blood flow in the veins of an immobilized or post-operative patient. The slow flow leads to the accumulation of activated clotting factors and tends to prevent their normal inactivation by the inhibitors described above. The handout discusses this further. The most dramatic example of hypercoagulability is disseminated intravascular coagulation, which can have many causes. As mentioned on a earlier page, certain serious, systemic inflections can trigger this state. It has the characteristics of a general, systemic inflammatory problem. Also, trauma, in general, potentially can lead to disseminated intravascular coagulation. Cancer can be another cause, probably through the entry of tissue factor into the blood. In all cases, many small clots form, blocking blood flow to widespread areas of the body. But since this is so widespread, it depletes platelets and clotting factors, leading to widespread hemorrhage. It is very easy for the sequence to fatal. Treatment involves reducing the tendency of the blood to clot with a drug such as heparin, while replacing the lost platelets and clotting factors. One cause of inadequate clotting is thrombocytopenia. Impaired clotting can be genetic due to lack of certain clotting factors (e.g. hemophilia) or lack of VWF. Or it can be due to impaired synthesis of clotting factors for other reasons. Vitamin K deficiency, which is required for the synthesis of several clotting factors, can be important here. Newborn infants, for example, may not have enough vitamin K.

Where does the blood go when it leaves the pulmonary artery?
Remember veins back to the heart. This goes into the heart to deliver oxygen.
What is the cause low red blood cell count?
White blood cells play an important role in theimmunity/immune system of an individual. The white blood cell count is performed routinely as part of a complete blood count. An unusually high white blood cell count can indicate an infection, hypersplenism, bone marrow depression (drugs, radiation or heavy metal poisoning) or primary bone marrow disorders such as leukemia. A low white blood cell count can be the result of infection, make an individual more susceptible to outside infections or allow multiplication of organisms within the body which would normally kept in check by a healthy immune system.White blood cells play an important role in the immunity/immune system of an individual.

Please note that it is extremely important to obtain an accurate diagnosis before trying to find a cure. Many diseases and conditions share common symptoms: if you treat yourself for the wrong illness or a specific symptom of a complex disease, you may delay legitimate treatment of a serious underlying problem. In other words, the greatest danger in self-treatment may be self-diagnosis. If you do not know what you really have, you can not treat it!

There are many different types and forms of white cells. Since deficiencies can affect one or more types or forms, a doctor's help and additional testing is usually required to understand the nature or cause of the deficiency.
Causes & Development ---- Neutropenia can occur in acute bacterial infections, viral infections, rickettsiae disease, some parasite injections, aplastic and pernicious anemia, acute lymphoblastic leukemia, some hormone imbalances and anaphylactic shock. LOW RED BLOOD CELL COUNT (Anemia, low hemoglobin, low hematocrit) Red blood cells carry oxygen and nutrients throughout the body. A complete blood count (CBC) is a blood test used to check your blood count. The RBC, hemoglobin, and hematocrit are tests to see if you have low red blood count. Normal Adult Values Male Female RBC 4.5 - 6.0 M/ul 4.2 - 5.4 M/ul Hemoglobin (HgB) 14 - 18 g/dL 12 - 16 g/dL Hematocrit (Hct) 40 - 52% 37 - 47% Note: Normal values will vary from laboratory to laboratory. When you have low red blood cell count you may feel: * Fatigued * Weak * Short of breath * Increase in your heart rate * Dizzy or lightheaded when you change positions quickly If you suffer from low red blood cell count, you may experience: * Headaches * Chest Pain * Pale skin Things you can do to help manage your low red blood count: * Rest between activities. * Plan ahead and save your energy for the most important activities. * Avoid or stop activities that make you short of breath or make your heart beat faster. * Ask others for help. * Eat a diet with adequate protein and vitamins. * Drink plenty of non-caffeinated and non-alcoholic fluids. When to call your doctor or health care provider about low blood counts: * Severe weakness. * You feel dizzy or lightheaded. * Your heart is beating faster. * You feel short of breath or are having difficulty breathing. * Call immediately if you are having chest pain. Your doctor or health care provider may prescribe or suggest to treat your low red blood count: * Epoetin alfa (PROCRIT®). * Darbepoetin (Aranesp®). * Iron supplement. * Multivitamin. * A diet high in protein. * A red blood cell transfusion.
What is the organ that houses developing lymphocytes?
The appendix is a narrow blind sac extending from the beginning of the colon that stores lymph cells. The appendix is a narrow blind ended sac that has nothing to do with lymph whatsoever. The lymph cells are stored in the lymph nodes.
How can you tell if you've lost too much blood?
Shock is the main consequence.
Hypovolemic shock is due to loss of blood and leads to the inability to get blood to the peripheral tissues/cells.
you get less blood volume in total because of losing lots,
you therefore have less in the system to be pumped around (so cardiac output decreases as does blood pressure and level of oxygen delivery)
the heart will beat faster to try to overcome this (tachycardia)
the vessel diameter will get smaller (vasoconstriction) to try to conserve blood
the kidney will synthesise aldosterone which will aim to maintain blood volume.
The person will be cold and clammy, tachycardic, thirsty and possibly confused
What does High white blood cell count and blood in urine mean?
Increased numbers of white blood cells in urine are usually a sign of a urinary tract infection or other renal diseases.
White blood cells are a normal component in the secretions of the male and female genital tracts and can be present in normal urine with concentrations of 0 to 8 cells per high-power field. Some laboratories culture urine with >5 white blood cells per high-power field to rule out a urinary tract infection.
Does getting your blood drawn hurt?
Not exactly, maybe a little, the only pain you can feel is the needle peircing your skin and the blood drain out but when its over you feel much better knowing what it's going to and that you are saving a life each pint you give.
What is the function white blood cell?
White blood cells (leukocytes) are the cells that travel throughout your body via the blood and fight infections and foreign items that enter the body. There are several different types of blood cells that each specialize in combating a particular foreign body. For example neutrophil are normally what people think of when people hear WBC's and they attack bacteria and fungi.
Blood if filtered by what organ?
The kidneys filter the blood of contaminants and of foreign substances that cause damage to the body.
How bad is 26000 in white blood cell count?
It means you're going to die soon. :(
What a pessimistic answer!!! It could be a number of things from appendicitis, bone marrow issues, immune system problems and even malnutrition. Most are treated very successfully!!
What does it mean when you have a high white blood cell count when pregnant?
White Blood Cells are part of a family of immune cells which attack "invaders" in the body. If you have an elevated WBC count it most likely means there is an infection in your body that is being fought off.
WBC is determined through a blood test known as a CBC or complete blood count.
As a side note, your lymphatic system is where WBC multiply, grow and build up to prepare for an attack.
Lymph nodes specifically are where WBC are located and as the lymph nodes become full of WBC the nodes become like little ball or bean shaped objects.
In some people you can feel the enlarged lymph nodes especially on the sides of the neck and this is normal. (Although lymph nodes can also be enlarged due to seasonal allergies(normal), cancer and other diseases which is not normal and should be checked out as soon as possible)
How long does alchohal stay in your blood?
Alcohol is generally no longer detectable in one to two hours, depending on the size and sex of the person. This also assumes one, one-ounce drink of alcohol, with no alcohol ingested for several hours or days before that. One ounce of alcohol will have a greater effect on a 100-pound female than it will on a 300-pound male. And whether fair or not, alcohol stays in a female's system longer than a male's because of the fact that women metabolize alcohol differently than men do.
What blood group can someone with type AB blood give blood to?
Only those with AB blood. However people with AB blood can receive blood from any time: A, B, AB or O.
While this is the case, it is still critically important for AB+ blood types to donate. AB+ is the universal recipient of other blood types but also the universal donor for plasma. Plasma is used in the treatment of blood disorders because it contains clotting factors, glucose, proteins, in helps in the regulation of electrolytes. Therefore AB+ blood is almost as highly sought as O-.
How long should it take to raise hemoglobin levels from a 7 range to normal?
I think you mean hematocrit. it was surprisingly fast. they said i couldn't give blood because mine was 36 (i lied and didn't wait long enough) and the min is 38. not even 2 weeks of a multivitamin and lots of spinach later and i was back up to my normal 40. Oh, and for breakfast i had oranges, kiwis, or any fruit for vitamin c that helps absorption of the iron. And then again before or after the spinach/banana smoothie - yum, health!
What is involved in red blood cell production?
Red blood cells are created and matured in bone marrow.
