hemosiderin in the liver, blood and other body tissues
◉ Deoxygenated hemoglobin (deoxyhemoglobin or reduced
hemoglobin) is. Answer: dark or bluish red in color and is found in
venous blood
◉ Breakdown of hemoglobin. Answer: - Heme is converted to
biliverdin
- Biliverdin is reduced to bilirubin: the yellow compound, carried to

◉ Blood clotting. Answer: the process by which blood becomes thick
and stops flowing, forming a solid cover over any place where your
skin has been cut or broken.
◉ Hemostasis. Answer: stoppage of bleeding
,◉ Blood clotting consists of. Answer: three steps
1) vasoconstriction or vascular spasm after injury
2) platelet clot
3) coagulation mechanism
Plasmin will eventually break down the blood clot
◉ Hemostasis step one. Answer: Damaged tissue and platelets
release factors that stimulate a series of reactions involving
numerous clotting factors, finally producing prothrombin activator
(PTA)
◉ Hemostasis step 2. Answer: 2. Prothrombin or factor II (inactive in
the plasma) is converted into thrombin. Thrombin is a
multifunctional molecule that functions as both a procoagulant and
an anticoagulant
◉ Hemostasis step 3. Answer: 3. Fibrinogen (factor I) is converted
into fibrin threads through the action of the thrombin.
, ◉ Hemostasis step 4. Answer: 4. A fibrin mesh forms to trap cells,
making up a solid clot, or thrombus, and stopping the flow of blood
◉ Hemostasis step 5. Answer: The clot gradually shrinks or retracts,
pulling the edges of damaged tissue closer together and sealing the
site.The circulating clotting factors are produced primarily
◉ Clot formation: production of prothrombin factor due to. Answer:
tissue damage
Prothrombin or factor II is converted into thrombin.
Thrombin converts Fibrinogen (factor I) into fibrin threads.
A fibrin mesh forms to trap cells.
The clot gradually shrinks or retracts, pulling the edges of damaged
tissue closer together and sealing the site.
