Overview of the Cardiovascular System

What does the cardiovascular system consist of?

• Heart, lungs, and blood

• Heart, blood vessels, and blood

• Lungs, blood vessels, and blood

• Heart, lungs, and blood vessels

What is the primary function of the cardiovascular system?

• To digest food

• To transport oxygen, nutrients, and waste products throughout the body

• To produce hormones

• To support skeletal structure

Which valves are included in the Atrioventricular Valves?

• Tricuspid and Bicuspid(Mitral) valve

• Aortic and Pulmonary valve

• Tricuspid and Pulmonary valve

• Bicuspid(Mitral) and Aortic valve

What is the function of arteries?

What happens after oxygenated blood returns to the left atrium through the pulmonary veins?

• Blood moves to the right ventricle

• Blood is pumped to the lungs

• Blood moves to the left ventricle and is pumped to the body via the aorta

• Deoxygenated blood enters the right atrium

What does systemic circulation do?

• Moves blood between the heart and lungs

• Distributes oxygen-rich blood to the body and returns deoxygenated blood to the heart

• Supplies the heart muscle with oxygen and nutrients

Which artery branches into the anterior interventricular artery (LAD) and circumflex artery?

• The left coronary artery.

• The right coronary artery.

• The brachial artery.

• The carotid artery.

What is the function of coronary veins?

• Return deoxygenated blood from the myocardium to the right atrium

• Supply oxygenated blood to the heart muscle

• Regulate the heart rate

• Control the opening and closing of heart valves

Where does the exchange of oxygen and carbon dioxide occur in the body?

• Arteries

• Veins

• Capillaries in the lungs

• Heart
