What role do valves play in the heart?
Valves help in pumping blood out of the heart.
Valves prevent the backflow of blood.
Valves oxygenate the blood.
Valves regulate the heartbeat.
What is the largest artery in the body?
Aorta
Pulmonary artery
Carotid artery
Femoral artery
Tiny branches connecting vein and artery vessels are called:
Arterioles

True/False: The flow of blood around the body ensures that essential nutrients are delivered and wastes are moved away for disposal. At the center of this system is the amazing pump, the human heart.
True
False
True/False: A series of tubes, or vessels, serve as the highways for the transportation of blood. Arteries are responsible for carrying blood back to the heart and veins are responsible for returning blood away from the heart.
True
False
True/False: Pulmonary circulation moves blood to the lungs to pick up oxygen and back to the heart so this oxygenated blood can be delivered.
True
False
True/False: Systemic circulation pumps oxygen rich blood to the body and returns deoxygenated blood back to the heart to be sent out for refueling.
True
False
True/False: The pulmonary arteries move blood from the heart (the right ventricle) to the lungs to pick up carbon dioxide.
True
False
True/False: Pulmonary Vein collects the oxygenated blood and carry it from the lungs back to the heart.
True
False
True/False: The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
True
False
True/False: The renal vein services the kidney and takes de-oxygenated blood back to the heart.
True
False
True/False: The femoral artery services the leg and takes de-oxygenated blood back to the heart.
True
False
True/False: The subclavian artery runs behind the clavicle and takes oxygenated blood from the heart and services the upper limb.
True
False

False
TRUE/FALSE: Minute volume is the volume of air remaining in the lungs after maximum exhalation.
True
False

True
False
TRUE/FALSE: Lung capacity is equal to VC + RV.
True
False
