Blood

leukemia

Oxygenated blood is bright red and deoxygenated blood is darker red.

A red blood cell placed in pure (distilled) water will explode because of osmosis.
Substances naturally seek equilibrium through osmosis by going from areas of high concentration to low concentration, the concentration of H2O is much greater outside the cell than inside and as a result water will rush into the cell and burst the membrane.

In general, a higher CEA level predicts a more severe disease, one that is less likely to be curable.

what a ? humman body blood circulation is 3-7 liter blood per minute.

Blood performs several vital functions within the body. Red blood cells carry oxygen which is necessary for the tissues of the body to remain alive and functional. White blood cells provide antibodies which fight infection and illness. Finally, platelets in the blood work to clot in order to stop unnecessary bleeding in the case of injury.

The inability of the blood to carry sufficient oxygen is very bad. This means that all cells will die quickly.

The function of the platelets is to clot blood.There for it stops blood from flowing if a body part is cut. maintainence of haemostasis.(process which causes the bleeding to stop.) platelets secrete platelet-derived growth factor(PDGF)

bone marrow

Everyone's blood cells have the same cell architecture and functional components (all blood cells are biconcave disks and contain hemoglobin unless there is a genetic disorder). However, the blood types are the result of different antigens (proteins, carbohydrates, glycoproteins, or glycolipids) on the surface of the blood cells. The most frequently seen A, B, AB and O blood system is caused by different carbohydrate antigens. People with type A have type A antigen, people with type B have type B antigen, people with type AB have both antigens, and people with type O have no antigens. These antigens facilitate rejection of blood by activating the immune system. It turns out that the immune system in a person whose blood does not have the antigen type in the transfusion blood recognizes the transfusion blood as foreign. This elicits an immune response to eliminate the 'invaders' and can result in the clumping of transfused blood cells due to antibody binding, causing the clogging of smaller vessels. Other blood type systems such as the Rhesus system involve other groups antigens on blood cell surfaces.

In an average healthy adult, the volume of blood is about one-eleventh of the body weight. Most sources state the volume of blood in an average human adult, who is between 150 to 160 pounds, as between 4.7 and 5 liters (around 5 quarts), although the more recent sources state the volume of blood in an average adult as 4.7 liters. Sources state that an 80-pound child had about half that amount, and an 8-pound infant has about 8.5 ounces. People who live at high altitudes, where the air contains less oxygen, may have up to 1.9 liters more blood than people who live in low altitude regions. The extra blood delivers additional oxygen to body cells. The heart pumps all the blood in the body each minute when the body is at rest.

Well it tastes like any normal drink. When you are a vampire you cant really taste the difference, its like cherryade without the fizz. Its delicious and Vampires just cant get enough of it. The favourite type of blood is O- type. That's really rare! VampireGirl1863 x

Platelets in the blood help to stem bleeding from a wound.

As much as it needs.

The normal heamoglobin value in human beings are as follows:

Men: 13.8 to 18.2 g/dl (138 to 182 g/l, or 8.5 to 10.6 mmol/L)

Women: 12.1 to 15.1 g/dl (121 to 151 g/l, or 7.5 to 9.3 mmol/L)

Children: 11 to 16 g/dl (111 to 160 g/l, or 6.8 to 9.9 mmol/L)

Pregnant women: 11 to 12 g/dl (110 to 120 g/l, or 6.8 to 7.4 mmol/L)

While technically there are more than one, the main one by far is sickle cell anemia.

Directly from my anatomy and physiology book - Marieb & Hoehn Eighth Edition:

"Lymphocytes originate in red bone marrow from hematopoietic stem cells."

" B cells become immunocompetent and self-tolerant in the bone marrow."

well...phagocytes are mainly part of the immune systems defense system, like when there is an inflammatory response. While lymphocytes are mainly for when the immune system attacks a foreign organism. However, lymphocytes can become phagocytes that's why i didnt say that they were part of a certain sector of the immune system.

hematoma
A mass of blood is called a Hematoma

Vitamin K is responsible for the clotting of blood..

Frequently the answer is "blood is blue inside us and red when it hits the air". Blood carries oxygen in our body so this really doesn't make sense. Blood is red with arterial blood being brighter and venous blood being darker. Our blood vessels have a bluish appearance through our skin but just as water going through PVC piping isn't white, blood isn't blue.

Anaemia is a sign which suggests that the the level of Haemoglobin in the circulating blood is low. It gives you a pale appearance, and will give rise to weakness, tiredness and dizzy spells. You will need to see your Doctor to investigate the cause of anaemia.

If lactic acid is excreted by the cells, then the blood would become more acidic, and the pH would drop.

If more Carbon Dioxide (CO2) is dissolved in the blood, then more carbon dioxide will mix with water to form:

CO2 + H2O --> H2CO3, Carbonic Acid, and the pH will also drop.

It can stay in your blood for as long as 2 months and urine for up to 30 days
