Heart 1

BLOOD VESSELS that carry OXYGENATED blood AWAY from heart to rest of the body

• veins
• arteries

BLOOD VESSELS that carry DEOXYGENATED 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

Blood vessels that carry blood back to the heart from lungs *but* they carry *OXYGENATED* blood.

• PULMONARY arteries
• aorta
• PULMONARY veins
• vena cava

Blood vessels that carry blood away from the heart *but* they carry *DEOXYGENATED* blood.

• aorta
• PULMONARY veins
• vena cava
• PULMONARY arteries

Part of the cardiac cycle where Ventricles relax: Semilunar valves shut to prevent backflow. Blood flows into ventricles from atria due to drop in pressure.

• diastole phase
• systole phase

Part of the cardiac cycle where Ventricles contract: Blood pumps out of ventricles, AV valves shut to prevent backflow.

• diastole phase
• systole phase

the transitional vessels between arteries and capillaries.

• ventricles
• Venules
• Arterioles
