Blood

Hemothorax is a medical term meaning blood in the chest cavity.

The blood from the body tissues arrives at the heart in vessels called the inferior and superior Vena Cavas. It enters the right atrium of the heart and is pumped passed the tricuspid valve into the right ventricle. Then a second, delayed contraction, pushes the blood through another valve, the pulmonary semilunar valve into the pulmonary trunk. From here the blood moves through the left and right pulmonary arteries and enters the left and right lungs where gas exchange takes place. Carbon dioxide is dropped off and oxygen is picked up by the hemoglobin of the blood by a process known as diffusion. Then oxygenated blood moves through the pulmonary veins to the heart and enter into the left atrium. This completes the pulmonary circuit of the cardiovascular system.

There are 2 types of white blood cells. They are called B cells and T cells. B cells put a "mark" on viruses. Then, T cells "kill" the viruses. BUT, if the B cells haven't "seen" the virus before. It will just "keep it's eyes open" (they don't really have eyes). If the same virus comes again, the B cell will remember and summon the T cells. Then, the T cells attack. Finally, it is game over for the virus.

Because some tubes have additives (ie Heparin and Potassium) that can contaminate the next blood tube and skew the results. For instance, if you put blood into the tube with Heparin and then the tube used for coagulation studies the Heparin has the potential to thin the blood in that tube giving you a falsely high result

There are many medications that can affect the results of the platelet aggregation test. The patient should discontinue as many as possible beforehand.

well you have to urinate in a glass of lemonade then mash some poo and place it in the cup then swallow (which works better ) or rub it on your legs and ankles

its about 6 inches

No white blood cells are not the part of platelets. Lymphocytes are originated from Lymphoid stem cells and function in specific immune reaction, Whereas platelets are formed by myeloid stem cell and involved in blood clotting and inflammation.

Very are very tiny and small. They are the smallest of the formed elements, or blood cells. The other larger ones are red and white blood cells.

Erythrocytes, or red blood corpuscles, are indeed enucleate . . . that is, have no nuclei.

They need the room for all the hemoglobin that they can carry. It also means that they can only live for about 120 days.

You don't lose much blood when you get cut because there are these tissues that stop the bleeding. Say if you get cut, then the tissues go to the cut a seal the opening of the place that you got cut so you don't lose blood. You need blood. Me... I fall A LOT and sometimes I get cuts on my body, but the tissues help me to keep my blood in my body. I hope this answer was what you was looking for :)

What is the difference between urea and BUN

You can donate your blood, but most places do not pay for it. If you want to make money, you will want to donate your plasma. They take part of your blood and put another part of your blood back in your arm. If you donate blood, you can only do this every 56 days. If you donate plasma, you can make money twice a week.

In one minute. But we all learned that in what? 5th Grade? Oh and spell *to* right u F*ck. It's not *yo* you dumba$$.

Yes, you can work out before donating blood. You should make sure you are adequately hydrated before donating, though.

As far as biological viruses, the prion is smaller than a virus. It it a misfolded protein.

In a word YES it can. And cardiac arrest is pretty final, not many people come round from it, unlike a heart attack which you may survive. This condition is in effect a state of Low Haemoglobin and should be investigated without delay. I would say anything below 10 should be cause for some concern with a base line of 6 to 4 being the lowest to safly sustain life, and really, you're pushing things a bit when you get this low.A bit like running an engine with no oil. If you want to avoid joining the Fairies you should see a doctor without delay.

oxygen

There are 3 out of 4 that are most common. Neutrophils, basophils, and eosinophils.

the passage of blood cells, esp. leukocytes, through the unruptured walls of the capillaries into the tissues.
Leukocyte extravasation is the movement of leukocytes out of the circulatory system, towards the site of tissue damage or infection. This process forms part of the innate immune response, involving the recruitment of non-specific leukocytes. Monocytes also use this process in the absence of infection or tissue damage during their development into macrophages.

plasma makes up 55% of your blood in your body

The normal range for granulocyte percentage is 45.5 - 79.7%, which translates into a normal granulocyte count of 2.2 - 8.8 x 10^3/uL. Granulocytopenia is an abnormally low concentration of granulocytes in the blood. This condition reduces the body's resistance to many infections. Closely-related terms include agranulocytosis (no granulocytes at all) and neutropenia (deficiency of neutrophil granulocytes). Transfusion of granulocytes would have been a solution to the problem. However, granulocytes live only ~10 hours in the circulation (for days in spleen or other tissue), which gives a very short-lasting effect. In addition, there are many complications of such a procedure. If you have a high percentage be happy!!!cheers
