Erythropoietin stimulates the production of proerythroblasts from the bone marrow.

Testosterone reduces the basal rate of erythropoiesis.

Hypoxia causes a marked decrease in erythropoietin levels.

Increased levels of erythropoietin result in increased circulating levels of red blood cells within 24 hours.

Erythropoietin is a hormone produced only in the liver.        

Increased blood CO₂ levels.

Damage to a blood vessel wall and subsequent exposure to collagen.

Infection in the blood.

Infection in the tissues.

Decreased blood oxygen levels.

Lymphocytes are the largest of all the white blood cells in humans.

Lymphocytes make up about 30% of leucocytes.

Leukaemia is a condition resulting from the uncontrolled production of white blood cells.

Lymphocytes have a single large non-segmented nucleus.

Lymphocytes are derived from committed lymphoid stem cells.

The extrinsic pathway is initiated by the release of factor III from damaged tissue to complex with factor VII and V.

The formation of a platelet plug is inhibited by healthy endothelium through the release of ADP.

Prothrombin is the enzyme that catalyses the conversion of fibrinogen into long fibrin fibres.

The intrinsic pathway is initiated by the activation of factor X.

Thromboxane A₂ is released by damaged vessel walls to initiate vasoconstriction.

If

the supply of iron in the diet falls, stored iron is released from ferritin.

Vitamin

C can increase iron absorption by oxidising ferrous ions to ferric ions.

Only

about 10% of ingested iron is absorbed into the body each day.

Free

iron will bind with apotransferrin to form transferrin, which can then be

transported in the blood.
