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.

Why the male hemoglobin level is different from female?
Hemoglobin is present in blood and carries oxygen to all parts of the body; males have high testosterone levels which are a very potent anabolic... due to these anabolic effects the hemoglobin levels are higher then females.
This is possible if the man is heterozygous for blood type A (Ai, not AA). Each parent passes down one allele to a child. So, if the woman is type O (ii) and the man is heterozygous for A (Ai), the child receives i from the mom and A or i from the dad. Consequently, the children can be either type O (ii) or A (Ai).
What ion is an essential factor in hemoglobin?
Hemoglobin contains a heme group with an Iron ion attached to it. This iron is what binds to O2.
How does bone marrow produce blood?
Red blood cells, which make up the bulk of blood, are produced from stem cells in the bone marrow. Stem cells reproduce in bone marrow and provide the raw material from which red blood calls can be produced.
A pluripotent (undifferentialted) stem cell becomes a multipotent stem cell, which in turn becomes a unipotential stem cell, which is to say it is now a specialized cell destined to become a specific type of blood cell. . After going through a few more stages it is released from the bone marrow, and ultimately becomes an erythrocyte, or mature red blood cell.
White blood cells, which are actually immune cells, are also produced in bone marrow from pluripotential hematopoietic stem cells, but go thorugh different stages to eventually become one of the six types of immune cells classified as white blood cells.
There are other componants in blood- plasma (the liquid componant), platlets, etc., which are produced by other specialized cells. Platelets, for example, are produced by megakaryocytes. Plasma is 90% water, but also contains other proteins, like albumin, that are produced by specialized marrow cells.
It carries nutrients from digested food yo all your cells
What is the function of globulins in blood?
Globulins come in two forms; Immunoglobulins or Antibodies that attack foreign proteins and disease-causing organisms. The other is the transport proteins that carry small ions, hormones and other compounds, these can be LDLs and HDLs. Hope this answers your question, it came from my text book.
Happy reading=)
What does it mean when a person poops blood?
This can mean that you have hemorrhoids, or intestinal polyps. Neither of these is terribly serious. But you need to see a doctor to be sure it is not something serious like cancer, or Crohn's Disease or any one of 3 or so other diseases that need to be diagnosed real soon.
Cold air does not cause a cold. Germs from a person with a cold is the only thing that causes a cold. Being out in cold air weakens your immune system making you more susceptible to contracting an unwanted illnesses. It is not the cold air itself that gets you sick.
Is it normal for a 12 year old male to be 5'10 and a size 14 shoe?
Yes. 5'8" is not tall but it is well within normal parameters. Both height and showe size are genetically determined. My husband and I have a male friend that has a Canadian size 15 foot for shoes and has a terrible time getting shoes or sneakers. He's just over 6' tall. It doesn't matter how big men's feet are they never look odd, but some poor women have very large feet and have difficulties getting nice shoes to wear.
Why might haemolysis of blood samples occur?
The disruption of red blood cell and release of their haemoglobin. There are several types of haemolytic reactions when bacteria such as streptococci or staphylococcus grow on blood agar.
Where are phagocyte cells made?
My teacher says it is found in the blood but, it basically meanders around so..... yea
What are the three substances carried in your blood?
Your blood has three types of blood cells that carry out different functions. One type of blood cell is a red blood cell (RBC) and its main job is to carry oxygen to the cells of the body, and help it get rid of carbon dioxide. The other kind of blood cell is a white blood cell (WBC) and its job is to fight off infections from foreign viruses or bacteria. Then there are the thrombocytes, most commonly referred to as platelets, and these play a major role in the clotting of blood.
The major ingredient in hemoglobin that allows oxygen to be transported is?
if you are looking for the range of a data you have to subtract the lowest number from the highest for example lets say you have 36,83,46,54,79 you would subtract 36 and 79 witch is 43 and 43 is the range of this data!
What does high gamma gt in blood mean?
The liver is a sort of chemical factory that makes some things that are essential to use in the body and it also breaks down and gets rid of some of the unwanted products of your body's chemical processes.
Some liver function tests, like the gamma GT (gamma-glytamyl transpeptidase), are very sensitive and can be raised by something as simple as taking paracetamol regularly and perhaps a bit too often, or as complicated as showing damage caused by too much alcohol.
Other liver function tests can be abnormal if certain drugs are making the chemical factory work too hard, or if the liver is being damaged by drugs.
Or it could mean that the liver is affected by an infection, like a viral hepatitis or damaged by some other disease process.
Do Veins serve as blood reservoirs?
Veins have strong celular walls & also contain valves.The valves stop blood from pooling backwards as the heart pumps blood around.
Its important to remember that blood in the veins is under low pressure & are returning blood back towards the heart & are de oxygenated.Arteries are larger & the blood in them is under very high pressure & is highly oxygenated.
Blood from veins is much darker as it has less oxygen being carried.Arterial blood is much lighter red colour as it is highly oxygenated.
What does blood do to stop our body from overheating?
Sweating secretes fluid onto your skin. As the heat in your body excites this fluid (heats it), it draws energy out of your skin and causes the fluid to evaporate. Since it is drawing thermal energy out of your skin, it cools, thus cooling the blood vessels in your skin (which are dilated due to your increased temperature). The effect is your skin cools and so does your blood. As the blood is pumped back towards your core, your core temperature drops.
What is a white blood count of 20.6?
Depends on the rest of the blood test and the reason for which you had a blood test. Alone, it doesn't mean much.
