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 arterial bleeding is difficult to control?
Because being closer to the beating of the heart, it has more pressure behind it. Arterial blood is "outboud". Venous blood is "inbound".
ANS2:Arterial bleeding is difficult to control because the pulsing pressure, delivered directly from the heart, makes clot formation less effective for staunching the flow than it would be for capillary or venous bleeding.What is the function of the T lymphocytes?
The function of lymphocytes are to prevent and eliminate the threats in our human body. It is capable of identifying if a cell is normal or infected. It also acts as an ANTIGEN.
What to do if count of hemoglobin is 8.2 during pregnancy?
You should be given iron injections and you must eat iron rich food to correct anemia.
It depends on how much blood was lost.
Up to 15% blood loss can be treated by drinking 3 times as much as was lost.
Between 15% and 30%, liquids should be given by IV
Between 30% and 40%, liquids by IV or blood transfusion
Over 40% - blood transfusion
our human blood types are controlled by many different alleles. A, B , AB , and O.
A and B are co dominant , which means that they share. That's why it's read as AB or something else :)
What type of mixture is red blood cells floating in plasma?
Colloid is the mixture when red blood cells are with plasma. This is part of the body.
What is the site where oxygen enters the pulmonary blood?

A chance of lupus. Follow up with your doctor. what about uera of 47 also a blood test
If blood entering the heart mixed with blood leaving the heart?
The heart has 4 chambers, the purpose of which is to send deoxygenated blood it receives from the body to the lungs, and to receive oxygenated blood from the lungs and to pump it all through the body. If through some problem the deoxygenated blood and oxygenated blood are mixed and sent out, then the % of oxygenated blood will be lower. Your whole body suffers when you don't get enough oxygen. If a heart has the kind of problem that causes this, the body could be in serious trouble.
What is the process when materials are exchanged between the blood and the body's cells called?
diffusion is when the materials go through the cell membrane between the capillaries (because capillaries are only one cell thick)
How does blood volum e affect blood flow?
Blood vessels alter blood flow by vasoconstriction and vasodilation. Chemicals that mediate vasoconstriction include serotonin and norepinephrine among others. Vasoconstriction works by contraction of smooth muscle lining the vessel walls and narrowing of the lumens of vessels, increasing blood pressure, but also increasing resistance. Chemicals that mediate vasodilation include acetylcholine, epinephrine and nitric oxide. During vasodilation, the muscles lining a vessel relax, increasing the space inside the vessel and slowing the velocity of blood flow. Blood flow velocity is highest in the arterial system, while slowest in the capillaries and venules; constriction increases the velocity of blood flow, while dilation increases blood delivery to the tissues. A system of valves in the lower extremities are used to create a pressure gradient that directs deoxygenated blood back up to the inferior vena cava.
When father is Rh positive and mother is Rh negative what type is the child?
It depends on the genotype of the parents: If they are AO and BO the child could be all of the 4 ABO-Bloodtypes: AO (= bloodtype A) BO (= bloodtype B) AB (= bloodtype AB) OO (= bloodtype O) If they are AA and BB the child could only be bloodtype AB If they are AO and BB the Child could be AB, or B (BO) If they are AA and BO the child could be AB or A (AO) In short, when the genotype is not given, the child can have any of the ABO-Bloodtypes
Does ice make your blood thin?

Do bedbugs bite certain blood types?
They dont always go after blood types, they just smell blood thats close to them, or at least a certain distance away.
Why would res blood cells burst if you placed them in pure water?
Naturally, solutes, like humans, hate to be crowded and like to have their own space. If given the opportunity, the solutes floating around in red blood cells would move through the cell membrane and float around freely outside. However, since the membrane is impermeable, the solutes draw water in. When too much water is drawn into the cell, the cell bursts.
This wouldn't be a problem if the surrounding water wasn't distilled and had a lot of solutes of its own. Then the solutes in the surrounding water would compete with the solutes in the red blood cell to pull water.
No. The usual garden slugs eat vegetation. Leeches, on the other hand, do suck blood, and they look a lot like slugs.
What does piru blood stand for?
bloods are red AND PIRU IS BURGUNDY. PLUS THEY STAND FOR DIFF. RIGHS
