Blood
Blood is a specialized bodily fluid in animals that delivers
necessary substances such as nutrients and oxygen to the
cells and transports metabolic waste products away from
those same cells.

TERM 34
Platelets
DEFINITION 34

hormone that stimulates the production of platelets
TERM 35
Hematopoiesis
DEFINITION 35
Haematopoiesis (or hematopoiesis in American English;
sometimes also haemopoiesis or hemopoiesis) is the
formation of blood cellular components.
Erythropoiesis
Erythropoiesis is the process by which red blood cells are
produced. It is stimulated by decreased O2 in circulation,
which is detected by the kidneys, which then secrete the
hormone erythropoietin.
TERM 37
Leukopoiesis
DEFINITION 37
Leukopoiesis is a form of hematopoiesis in which white blood
cells are formed in bone marrow located in bones in adults
and hematopoietic organs in the fetus.

Steps in Clotting
thromboplastin released by platelets and damaged vessel tisue
this stimulates - prothrombin an inactive enzyme that is found in
bloodProthrombin when activated becomes thrombinThrombin
converts molecules of the protein fibrinogenfibrinogen when
activated becomes fibrinfibrin is an insoluble fiber that traps RBC's
to form clotsThroboplastin, prothrombin, thrombin, fibrogen, fibrin,
blood clot
