|
Definition
Unable to divide, grow, or synthesize proteins
Wear out in 100-120 days
When worn out, RBCs are eliminated by phagocytes in the spleen or liver
Lost cells are replaced by division of hemocytoblasts in the red bone marrow |

|
Definition
Vascular spasms
Platelet plug formation
Coagulation (blood clotting) |
|
|
Term
| What are vascular spasms? |
|
Definition

Term
| What is platelet plug formation? |
|
Definition
Collagen fibers are exposed by a break in a blood vessel
Platelets become "sticky" and cling to fibers
Anchored platelets release chemicals to attract more platelets
Plateles pile up to form a platelet plug |
|
|
Term
|
Definition
Injured tissues release tissue factor (TF)
PF3 (a phospholipid) interacts with TF, blood protein clotting factors, and calcium ions to trigger a clotting cascade
Prothrombin activator converts prothrombin to thrombin (an enzyme)
Thrombin joins fibrinogen proteins
Fibrin forms a meshwork |
