Blood group AB individuals have both A and B antigens on the surface of their RBCs, and their blood serum does not contain any antibodies against either A or B antigen.
blood pressure varies with age and sex of the individual. A rough rule of thumb for normal systolic pressure is 100 _ age of individual. In children 2 x (age) _ 80 = systolic bp The diastolic pressure should be roughly 2/3 the systolic pressure.

Blood
Blood is a liquid tissue. Suspended in the watery plasma are seven types of cells and cell fragments.
Blood islands
Masses of splanchnic mesoderm that form the first red blood cells and blood vessels. Found in the gut wall of amphibians and the yolk sac of amniotes.

also known as angiogenetic clusters; masses of splanchnic mesodermal cells found in the yolk sac of amniotes. The first blood forming tissue of the embryo, responsible for red blood cells and vitelline blood vessels.
Cold-blooded organisms, more technically known as poikilothermic, are animals that have no internal metabolic mechanism for regulating their body temperatures.
The Blood
The blood is an opaque, rather viscid fluid, of a bright red or scarlet color when it flows from the arteries, of a dark red or purple color when it flows from the veins.
These Streptococci Kill White Blood Cells
Although a neutrophil can kill this bead-like string of Streptococcus pyogenes, this particular strain of bacteria expresses streptolysin-s on its surface which kills the white cell through necrosis, ...
blood -- Fluid which circulates throughout the body of an animal, distributing nutrients, and often oxygen as well.
blood group or type One of the classes into which blood can be separated on the basis of the presence or absence of certain antigens; notably, the ABO types and the Rh blood group.

A type of connective tissue with a fluid matrix called plasma in which blood cells are suspended.

BLOOD CLOT
The circulatory system consists of a heart (or hearts) which is a bigger, pumping muscle and blood vessels. Some vessels lead away from the heart (arteries) and some toward the heart (veins). The arteries have thicker walls than the veins.
blood type Characteristic of human blood given by the particular antigens on the membranes of the erythrocytes, genetically determined, causing agglutination when incompatible groups are mixed; the blood types are designated A, B, O, AB, Rh negative, ...

i i = blood type O
People with blood type A have a specific kind of carbohydrate chain on the surface of their red blood cell. The carbohydrate chain is attached to a membrane protein or lipid.
As your blood travels along within your body, it becomes more and more polluted with urea and other wastes. Eventually the blood enters a special filter. An organ known as your kidneys. As the blood enters your kidneys it is cleansed.
Without a blood supply, tumor cells also cannot spread, or metastasize, to new tissues. Tumor cells can cross through the walls of the capillary blood vessel at a rate of about one million cells per day.

An X-linked recessive genetic disease, caused by a mutation in the gene for clotting factor VIII (hemophilia A) or clotting factor IX (hemophilia B), which leads to abnormal blood clotting. Herbicide.
Alpha-fetoprotein (AFP) -- a protein excreted by the fetus into the amniotic fluid and from there into the mother's bloodstream through the placenta.
Now your spleen is very good at raking these cells out of the peripheral blood as they come through. And that's what causes the anemia, and the old name for sickle cell was sickle cell anemia. However, though, short polymers are very, very dangerous.
Bergmann's Rule: The colder the climate (thus, usually, the higher the latitude) the larger the body size of a warm blooded animal when compared to close relatives in warmer regions.
Critically impaired gas exchange to the brain due to decreased oxygen (hypoxia) or reduced blood flow (ischaemia) is a major cause of brain injury in the perinatal period.
The primary hosts for HIV are the white blood cells variously called helper T lymphocytes, helper T cells, or CD4+ T cells.
A good example of this is blood sharing in vampire bats. In these bats, those lucky enough to find a meal will often share part of it with an unsuccessful bat by regurgitating some blood into the other's mouth.
As blood is pumped from the heart, it passes through a system of arteries, arterioles, and then capillaries. The capillaries are the vessels that allow for most of the transfer of compounds and dissolved gases.
pst infected blood in the crop and so passage of infected blood to bitten individuals. Subsequent mutations in the bacterial chromosome may have removed the (now unecessary) ability of the bacterium to colonise the mammalian host's gut.

Cancer of the developing blood cells in the bone marrow. Leukemia leads to rampant overproduction of white blood cells (leukocytes); symptoms usually include anaemia, fever, enlarged liver, spleen, and/or lymph nodes. [Talking Glossary]

It is now known that stem cells can also be obtained from placenta and amniotic fluids, and pluripotent cells can be derived from adult cells of the skin, blood and other tissues.
