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.

What is normal vitamin B12 result in blood test?
For a healthy young adult, the daily recommend intake is 2.4 mcg.
For pernicious anemia or other digestive issues you should take 1000 mcg per week.
Elderly people may benefit from 10 to 25 mcg per day of vitamin B-12.
You can take B-12 orally, as either pills or sublingually. (ineffective for people with stomach surgery or pernicious anemia). You can also get B-12 delievered directly to the bloodstream via injections or B-12 transdermal patches.
What is normal renal blood flow?
about 350 liters of blood pass in one day, so divide 350 liters by 24 which is about 14.5 liters per hour.
What is the medical term meaning abnormal increase in red blood cells?
Macrocytosis is the term meaning abnormally large red blood cells. Macrocytosis is seen in a number of RBC disorders. Megaloblastic anemia is one of the best characterized ones. It is cause by vitamin B12 deficiency.
Is the blood blue inside the body?
It's not really blue. The changes in blood coloration you're describing relate to the respiratory pigment, hemoglobin. Hemoglobin is a topologically complex molecule that very readily binds to oxygen. Once the molecule is fully saturated, it reflects in the crimson red spectrum, and therefore fully oxygenated blood appears to be bright red. After the hemoglobin molecule gives up its oxygen to tissue that needs it, the molecule becomes much less reflective, and thus deoxygenated blood appears very dark red to purple, or almost black. Blue is used in charts and diagrams to contrast against red, red being the arterial system bearing O2 and blue being the deoxygenated blod or venous system.
What happens if you drink someone else's blood?
Chances are, you would get pretty sick. When the blood hits the the digestive acids in the stomach, it will congeal within seconds. Most people wind up vomiting if there is more than a few milliliters of blood in the stomach.
What happens when a person has loss of blood?
The body compensates by entering Hypovolemic shock. Hormones get released that will constrict your peripheral blood vessels to keep your blood in your core. Your heart rate will increase and your respiratory rate may increase as well.
If left untreated your body will fatigue and your breathing will diminish as will your heart rate.
What is the HCT in red blood cells?
G HTC might refer to the gyro accelerator included in HTC phones that allow the phone to know its position to the horizontal. It helps the phone to perform some tasks with ease like mute the phone by turning it upside down, lowering the volume on pick up and many more. There are some games on the market that use this G for fun.
What receives low oxygen blood from all parts of the body?
All veins (except for the pulmonary vein) receive and carry oxygen poor blood. This oxygen poor blood enters the heart through the superior & inferior venae cavae to the right atrium and ventricle. It is then carried by the pulmonary artery to the lungs for oxygenation.
How do you take a blood pressurer?
Blood pressure is an expression of the strength of arterial circulation in a human or animal. To measure the flow, one uses a pressure meter or 'sphygmomanometer', comprising an inflatable cuff to restrict blood flow, and a mercury or electronic manometer to measure the pressure.
The pressure is stated as two numbers, the highest pressure that blood reaches (pushes past the cuff) and the lowest (the flow is unimpeded and flows without being pushed by the heart contraction). The higher pressure is the systolic (heart pushing), the lower the diastolic. Blood pressure is stated as both of these numbers, e.g. 115/75 spoken "115 over 75" is a systolic pressure of 115 (mm Hg), a diastolic of 75 (mm Hg).
*For SI conversion, the mm of mercury, also known as the Torr (for Evangelista Torricelli), is equal to approximately 133.3 Pascals.
BP can be measured using palpation in emergency situations. This only gives a rough estimate of systolic pressure. It can be used with the carotid, the femoral, or radial pulse.
Normally, manual sphygmomanometers are used in conjunction with a stethoscope to determine the two pressures. You use a BP cuff, pump it up until the pressure in the cuff is 20 mm Hg above the pressure in the artery. Using a stethoscope you can hear when this happens. No sound is heard in the artery.Then the pressure is released and when the pressure is heard again the second reading is made.
Another method of measurement is invasive, intra arterial pressure monitoring. This is where an arterial line is inserted into an artery and taped into place, with a bag of pressurised fluid preventing the backflow of blood from the artery (as it is under a lot of pressure in an artery). The line is used to sample arterial blood flow to measure dissolved gases in it and measure arterial blood pressures continuously.
What color top tube is used for hemoglobin test?
If your asking about what colored tubes blood is taken in, it's usually purple or lavender colored for CBC's (complete blood count). If you need blood, a Pink or larger purple/lavender top will be drawn for Blood Bank matching.
What is normal white blood cell count for a child of 1 year old?
what is normal wbc count in 2 to 3 yrs old boy
What is red blood cells and there function?
The RBC's (red blood corpulsces) contain haemoglobin which helps in transport of oxygen and other important things to various places in our body..
The combine oxygen with them and forms oxyhaemoglobin
Hb + O2
= HbO2
What are the 4 things that make up the blood?
Red blood cells, white blood cells, platelets and plasma. :P
What would happen to you if you lost 3 pints of blood?
it means your wallet will burst because you cannot spend asmuch money at the pub
What carries blood around in the body?
the CIRCULATORY SYSTEM or sometimes termed as the cardiovascular system.
they are smaller parts of this system the things that the blood goes though
arteries- carry blood away from heart
veins - carry blood back to the heart they also have occasional valves to make sure the blood all goes in one direction
capillaries are tiiny vessels that carry blood close to the body's cells in its tissues and organs
How much Blood in a newborn baby?
To estimate blood volume of a new born baby the following calculation is used:
EBV= weight (kg) * Average blood volume
Average blood volume for a full term neonate is 85 mL/kg
Average blood volume for a premature neonate is 95 mL/kg
Why do you need to wipe off the first blood drop?
The first drop of blood is generally diluted with the sanitizer used to clean your arm/finger/etc. Therefore, to get an accurate test result, the first drop needs to be discarded and fresh blood needs to be collected.
Where to start. Macrophages(white blood cells and other "cleaner cells) red blood cells which contain myoglobin hemoglobin etc. Iron sodium potasium calcium magnesium and about 24 other vital elements and compounds along with monosachrides. All of the hormones such as thyroxin hgh fsh and etc. Im positive ive left stuff out but this is a very basic concept
What is normal count for platelets?
The normal platelet count range in children is between 150,000-450,000 per μl.
What part of the blood is mostly water?
Plasma is the component of blood that is made up of 90% water. It is a yellowish fluid, which carries nutrients, minerals, water, hormones, protein and waste products
What organ Removes urine and salts from the blood forming urine?
kidnyes are in control of the water and it doesn't remove it it regulates it so thers never to much and never to little how much water depends on your salt intake. the lung regulates the carbon dioxide.
How many platelet transfusions can a leukemia patient have?
As many as necessary to prevent bleeding associated with thrombocytopenia.
In patients refractory to random donor platelet transfusions, platelet crossmatching may identify units providing better platelet count increases. If crossmatching is not effective, HLA matching of platelets may be necessary.
