Anticoagulants

• Thin the blood
• Thicken the blood
• Allow blood to flow freely
• C. is most accurate

Platelets can expand and contract

• Yes
• No
• Maybe

Steps 1, 2 and 3 of Hemostasis are:

• Abrasions, lacerations and incisions
• Vasoconstriction, Platelet Plug formation and formation of fibrin blood clot
• Fibrins, warfrin and Coumadin

The mesh network is formed of

• thrombin
• prothrombin
• fibrin
• fibrinogen

The vitamin essential for blood clotting

• Vitamin A
• Vitamin B
• Vitamin K
• Vitamin C
