What are critical components of coagulation?

AKA blood clotting

• Prothrombin
• Thrombin
• Fibrinogen
• Fibrin

What are the formed elements of the blood?

• RBC's
• WBC's
• Platelets

What type of drug is heparin?

Anti-Coagulant: to prevent blood clots

(blood thinner)

What are the parts of leukocytes?

• Granulocytes (Neutrophils, Eosinophils)

Agranulocytes (Lymphocytes, Monocytes)

What is the largest type of leukocyte?

Describe red blood cells.

• No Nucleus and shaped like tiny biconcave disk
• Do not contain ribosomes, mitochondria, or other organelles typical of most body cells
• primary component is hemoglobin
• most numerous of the formed elements

Know what makes up blood plasma.

What percent of whole blood constitutes what percent of body weight?

• 8% of total body weight
• Of that: plasma-55% and formed elements-45%

3 stages:

1. Production of thromblastin activator 
2. Conversion of prothrombin to thrombin
3. Conversion of fibrinogen to fibrin and production of fibrin clot.
