Process of formation of blood is
-
Haemolysis

Plasmolysis

Haemopoiesis

Haemoneogenesis
Blood is a special connective tissue consisting of a fluid matrix, plasma, and formed elements. The process of formation of blood is called Hemopoiesis. It takes place in red bone marrow found in the epiphysis of long bones.flat bones(ribs and cranial bones), vertebrae and pelvis.
Bone marrow takes part in __________________.
-
Controlling blood pressure
-
As haemopoietic tissue
-
Assisting kidneys
-
Assisting liver
Bone marrow is a semi-solid tissue which may be found within the spongy or cancellous portions of bones. In birds and mammals, bone marrow is the primary site of new blood cell production or hematopoiesis. It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.
Granulocytes are formed inside _____________.
-
Liver
-
Red bone marrow
-
Kidney
-
Small intestine
Granulocytes are a category of white blood cells characterized by the presence of granules in their cytoplasm. Granulocytes are produced via granulopoiesis in the bone marrow.
Red blood cells are produced$/$ erythropoiesis occurs in _____________.
-
Bone marrow
-
Spleen
-
Liver
-
Thymus
Erythropoiesis is the process which produces red blood cells, which is the development from erythropoietic stem cell to mature red blood cell. this usually occurs within the red bone marrow. In the early fetus, erythropoiesis takes place in the mesodermal cells of the yolk sac. By the third or fourth month, erythropoiesis moves to the liver. After seven months, erythropoiesis occurs in the bone marrow.
Highly Haematopoietic organs in embryo are ___________.
-
Spleen
-
Lymph-nodes
-
Bone -marrow
-
All
Hematopoiesis is the formation of blood cellular components. In developing embryo, blood formation occurs in aggregates of blood cells in the yolk sac called, blood islands. As development progresses, blood formation occurs in the spleen, lymph nodes, and liver.
Both erythrocytes and leucocytes are formed in ___________.
-
Thymus
-
Bone marrow
-
Arterial walls
-
Lymph nodes
Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities
Platelet plug is associated with.
-
Clot retraction
-
Haemostasis
-
Fibrin formation
-
Homoeostasis
The platelet plug, also known as the hemostatic plug or platelet thrombus, is an aggregation of platelets formed during the earlier stage of hemostasis in response to blood vessel wall injury. After platelets are recruited and begin to accumulate around the breakage, their “sticky” nature allows them to adhere to each other. This forms a platelet plug, which prevents more blood from leaving the body as well as any outside contaminants from getting in. The plug provides a temporary blockage of the break in the vasculature. As such, platelet plug formation occurs after vasoconstriction of the blood vessels but before the creation of the fibrin mesh clot, which is the more permanent solution to the injury. The result of the platelet plug formation is the coagulation of blood. It can also be referred to as primary hemostasis.
Bone marrow of long bones are the sites of
-
Production of WBC's
-
Production of RBC's
-
Production of blood
-
Breakdown of RBC's
Formation of red blood is called _____________.
-
Haemocytosis
-
Haemolysis
-
Haemopoiesis
-
Haemocytolysis
Blood cell formation also called Hematopoiesis, or Hemopoiesis is a continuous process by which the cellular constituents of blood are replenished as needed. It occurs in the bone marrow.

-
Haemolysis
-
Rouleaux
