Heart Anatomy & Physiology

The process of stopping bleeding: vasoconstriction, platelet plug formation, blood clot formation

• hemostasis
• hemocytoblast
• hemopoeisis

A type of blood clot formed within a blood vessel and remains attached to its place of origin.

• embolus
• thrombus
• platelet plug

A type of clot that breaks lose and travels through the bloodstream. (dangerous!)

• thrombus
• platelet plug
• embolus

A structure that forms when platelets stick together at the site of an injury in a blood vessel to reduce or stop minor bleeding.

• embolus
• thrombus
• blood clot
• platelet plug

A structure that forms on top of a platelet plug to provide a more stable "bandage". This allows tissue repair to occur. It is made of fibrin which acts as a net to trap other formed elements.

• blood clot
• thrombus

BLOOD VESSELS that carry blood AWAY from heart

• veins
• arteries

BLOOD VESSELS that carry blood back toward the heart

• arteries
• arterioles
• veins

BLOOD VESSELS that allow for gas (O₂/ CO₂) and nutrient exchange.

• arteries
• arterioles
• veins
• capillaries

TYPE of blood flow that cycles to the body tissues; allows for oxygen to be distributed to all the cells of the body.

• systemic circulation
• pulmonary circulation

TYPE of blood flow that cycles from the right ventricle to the lungs and back to the left atrium

• systemic circulation
• pulmonary circulation
