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 hereditary blood clotting disorder?
There are several such diseases. The most well known is hemophilia.
What happen to the hematocrit when you have hemorrhage?
The hematocrit calculates the percentage of red blood cells in the plasma. The term hematocrit means to separate blood. Brain hemorrhage is caused by an artery in the brain bursting and causing bleeding in surrounding tissues. A hematocrit that is done immediately after a hemorrhage does not show any signs of RBC loss because at the time of the hemorrhage, plasma and red blood cells are lost in equal proportions.
A normal total white blood cell count is 5000-10000 (with some local laboratories having some slightly different ranges.) The total count is broken down in to lymphocytes, granulocytes, and monocytes. The granulocyte count is generally what is used to determine if a person is able to have a chemotherapy treatment.
Any illness with a significant raised WCC (white blood cell count) especially at an abnormal level like this, with other symptoms point to leukaemia. WCC, is raised in infection as well as inflammatory conditions, eg asrthritis. however, not as high as what would be seen in leukaemia
What organ produces and removes red blood cells?
The liver and kidneys filter the blood. The bones produce most of the white blood cells. However, T and B lymphocytes are produced in the lymph nodes and spleen, and the T Cells are also produced and mature in they Thymus Gland. The bone marrow is the part of the bone that produces the cells
Is 1.2 low for a white blood cell count?
Yes. I am currently in hospital (I have CF) and expecting to be released tomorrow though they said it may not be the case as I have a low blood cell count of 1.2. However, they didn't say there was no chance in going home so it can't be too low, I hope!

What happen if platelets is below normal counts?
A normal platelet count is between 150,000–400,000 platelets per cubic millilitre of blood. In mild cases of thrombocytopenia, the count is between 100,000–150,000. In severe cases, the count can be close to zero. If the platelet count falls below 30,000, the risk of uncontrolled bleeding is high and could be life-threatening.
Platelets also carry serotonin and L-tryptophan, two substances involved in sleep/wake cycles, appetite, and mood regulation.
What does low rbc hemoglobin hematocrit indicate?
A low hemocrit level is termed anemic, there are many contributors to the condition; surgery, bleeding, colon cancer. A high hemocrit level occur when people live in higher elevation, chronic smokers, dehydration and sometimes lung disease.
What is the decrease in the number of neutrophils?
The medical term for a decrease in the neutrophil count is neutropenia. Some of the causes for decreased neutrophil or white blood cell count include congenital disorders, infections, hypersplenism and vitamin deficiencies.
A high white blood cell count usually indicates that an infection is present. White blood cells protect the body against infection by eating viruses.
What kind of white blood cell means you have cancer?
There is no particular type of white blood cell that indicates a patient has cancer. Physicians may do a blood test to see if a patient has a large number of white blood cells, consistent with some types of blood cancers, but having a particular white blood cell kind doesn't indicate cancer in anyone.
Does fever cause high iron in blood?
No. Anemia does not causes high fever. High fever may cause anemia like in malaria.
Why does sickle cell hemoglobin migrate slower than normal hemoglobin during gel electrophoresis?
because of the change of AA- in normal cell- from Glutamic acid (negativity charged) to Valine (uncharged) -in sickle cell- the charge will be missing in the sickle cell
that why the electrophoresis will become slower because of the missing charge
Does hemothorax mean blood in the chest?
Hemothorax is a medical term meaning blood in the chest cavity.
What vessels entering right atrium?
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.
