describe in detail the site of blood formation in foetus and adults
The process of blood formation is hematopoiesis. It mostly occurs in the bone marrow but under certain conditions can take place in the liver, spleen and other places.
When rouleaux formation is truly present, it is caused by an increase in cathodal proteins, such as immunoglobulins and fibrinogen.And the fibrinogen is not present in blood in vivo*This is not true. Fibrinogen is secreted by liver and is present in blood. The reason rouleaux do not form in vivo is that they only form under low shear stress conditions. With blood flow, the cross-sectional fluid velocity gradient in the blood vessel results in shear stress levels that exceed the threshold for rouleaux formation.
Neutrophils do. The approximate percentage of basaphils in adults is only 1% while neutrophils ranges from 54% to 62%
Hematopoiesis

Red bone marrow
The process of blood formation is hematopoiesis. It mostly occurs in the bone marrow but under certain conditions can take place in the liver, spleen and other places.
haematopoiesis is the term given to the production of blood cells.
urine formation begins in the glamerulus where blood moves through afferent arteriole into glamerulus and where filteration begins
. What is the relation of blood pressure and blood colloids to urine formation?
osteogenesis
Cerebrovascular Disease refers to a group of conditions that come together to collectively affect blood flow to blood vessels in the brain, which can occur from narrowing of blood vessels and even the formation of blood clots.
Normally the beginning of a blood clot, platelet plug formation, doesn't occur unless the platelets are exposed to the underlying collagen fibers. That doesn't happen unless the blood vessel has been damaged so clots usually only occur in response to a damaged blood vessel.
Hemostasis means control of blood flow. Hematopoeisis means blood formation.
Earthquakes occur at that moment
Infants are most susceptible to developing arachnoid cysts, although cyst formation can occur up through adolescence. Arachnoid cyst development in adults occurs much less frequently. Arachnoid cysts occur predominantly in males.
