Circulatory System Review

Overall purpose of the circulatory system.

• To push blood throughout the body to deliver oxygen and nutrients and eliminate waste and carbon dioxide.

• To filter toxins from the blood and produce urine.

• To transport hormones and regulate body temperature.

• To provide structural support to the body and protect organs.

Blood vessel that carries deoxygenated blood out of the heart and to the lungs.

• Pulmonary Artery

• Aorta

• Coronary Artery

• Pulmonary Vein

Our blood carries both ________ and _________ to our organs.

• Oxygen and Nutrients

• Carbon Dioxide and Waste

• Hormones and Enzymes

• Heat and Water

Overall path of blood through the body. The start is arbitrary.

• Veins -> Atriums -> through valves -> ventricles -> arteries -> body -> veins

• Arteries -> Ventricles -> through valves -> Atriums -> veins -> body -> arteries

• Veins -> Ventricles -> arteries -> body -> Atriums -> through valves -> veins

• Atriums -> body -> veins -> arteries -> ventricles -> through valves -> Atriums

Arteries

• Blood vessels that carry oxygenated blood away from the heart.

• Blood vessels that carry deoxygenated blood to the heart.

• Blood vessels that exchange nutrients and waste with tissues.

• Blood vessels that transport hormones throughout the body.

Veins

• Blood vessels that carry oxygenated blood away from the heart.

• Blood vessels that carry deoxygenated blood toward the heart.

• Blood vessels that transport nutrients to the body.

• Blood vessels that filter waste from the blood.

Capillaries

• Large blood vessels that carry oxygenated blood away from the heart.

• Extremely small blood vessels that allow for the passage of nutrients and oxygen to the organs.

• Veins that return deoxygenated blood to the heart.

• Arteries that supply blood to the lungs.

What type of blood enters the right atrium from the body?
