|
|
|
3 blood cells:
|

nucleus
|
|
|
Erythrocytes are given their red color by:
|

special proteins
|
|
|
The life span of an erythrocyte is ___ to ___ days
|

|
|
|
Leukocytes (white blood cells) serve as part of the body's immune system by protecting the body from :

invading bacteria, viruses and other pathogens
|
|
|
Thrombocytes are also known as
|
platelets
|
|
|
The three main mechanisms for blood clotting are:
|
A platelet plug, vascular spasm, and coagulation.
|
|
|
When a smooth muscle is torn it begins to ____ reducing the blood flow.
|
spasm
|
|
|
When platelets come into contact with the damaged blood vessel their physical characteristics change by becoming larger and sticky causing them to clump together and form a _____.
|
platelet plug
|
|
|
_____ is the process of transforming fibrinogen into fibrin threads that tighten the platelet plug into a clot.
