• Increased risk of heart disease

• Improved heart function

• No effect

• Decreased blood pressure

What does an increased SV (Stroke Volume) specifically indicate?

• Decreased size of the left ventricle

Calculate the stroke volume for a fit heart if the heart rate is 40 bpm and the cardiac output is 5.4 L.

• 135 ml

• 120 ml

• 150 ml

• 100 ml

Match the following cardiovascular terms with their definitions:

• Small blood vessels that branch out from arteries and connect to capillaries.

• Arterioles

• Small blood vessels that connect capillaries to veins.

• Aorta

• The main artery that carries oxygenated blood from the heart to the rest of the body.

• Pre-capillary sphincters

• Bands of muscle that regulate blood flow into the capillaries.

• Venules

• Tiny blood vessels that link arterioles and venules, allowing for the exchange of gases, nutrients, and waste products.

• Capillaries
