Blood formation, or hematopoiesis, primarily occurs in the bone marrow of adults. The bone marrow contains stem cells that can differentiate into various blood cell types, including red blood cells, white blood cells, and platelets. In certain situations, such as severe blood loss or specific medical conditions, blood cell production can also occur in other organs like the liver or spleen.
In the fetus, blood formation occurs mainly in the liver and spleen during the early stages of development and later shifts to the bone marrow. In adults, blood formation primarily takes place in the red bone marrow of the axial skeleton (such as the sternum, ribs, vertebrae, and pelvis) and proximal epiphyses of the long bones (such as the femur and humerus). The bone marrow contains stem cells that differentiate into various blood cell types, including red blood cells, white blood cells, and platelets.
Blood platelet plug formation is the process by which platelets in the blood adhere to the site of a damaged blood vessel, become activated, and aggregate to form a plug that helps stop bleeding. This plug is a temporary seal until more permanent blood clotting can occur to heal the damaged vessel.
Blood formation, or hematopoiesis, occurs in the bone marrow. This process involves the differentiation of hematopoietic stem cells into various blood cell types, such as red blood cells, white blood cells, and platelets. These cells are then released into the bloodstream to perform their respective functions in maintaining homeostasis and fighting off infections.
Rouleaux formation, which is the stacking of red blood cells, does not typically occur in vivo due to the flow dynamics in blood vessels. The force of blood flow helps to separate and prevent red blood cells from sticking together. Additionally, the presence of plasma proteins like albumin helps to maintain the cells in a dispersed state.

Red bone marrow
In the fetus, blood formation occurs mainly in the liver and spleen during the early stages of development and later shifts to the bone marrow. In adults, blood formation primarily takes place in the red bone marrow of the axial skeleton (such as the sternum, ribs, vertebrae, and pelvis) and proximal epiphyses of the long bones (such as the femur and humerus).

urine formation begins in the glamerulus where blood moves through afferent arteriole into glamerulus and where filteration begins
Blood platelet plug formation is the process by which platelets in the blood adhere to the site of a damaged blood vessel, become activated, and aggregate to form a plug that helps stop bleeding. This plug is a temporary seal until more permanent blood clotting can occur to heal the damaged vessel.
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.
osteogenesis
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.
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.

Rouleaux formation, which is the stacking of red blood cells, does not typically occur in vivo due to the flow dynamics in blood vessels. The force of blood flow helps to separate and prevent red blood cells from sticking together.
