Cardiovascular System (HARD)

1. Heart rate multiplied by stroke volume equals what?

• Heart beat

• Cardiac output

• Systole

• Cardiac cycle

1. Blood cells make up what percent of blood volume?

• 30

• 40

• 45

• 55

1. Vasodilation is…

• When blood vessels decease in diameter

• When blood vessels increase in diameter

• A rise in core body temperature

• A decrease in core body temperature

The pulmonary artery leads to the…

• Body

• Right atrium

• Lungs

• Left ventricle

1. The atria are the upper chambers that…

• Pump blood around the body

• Pump blood to the lungs

• Receive blood from the ventricles

• Receive blood from the vena cava

After receiving blood from the pulmonary vein, the blood will take the route of…

• Left atrium, left ventricle, aorta

• Right atrium, right ventricle, aorta

• Left ventricle, left atrium, aorta

• Right ventricle, right atrium, aorta

Stroke Volume is measured in:

• Litres

• Millilitres

• Kilolitres

• Centilitres

The process of blood vessels decreasing in size and blood flow reduction is known as:

• Hypothermia

• Hyperthermia

• Vasodilation

• Vasoconstriction

The role of capillaries is to:

• Carry oxygen and nutrients to cells, and take carbon dioxide away from the cells

• Carry deoxygenated blood and waste away from body cells and to the heart

• Take oxygenated blood to the heart

• Maintain oxygen levels in blood

Large, thick walled blood vessels are:

• Veins

• Capillaries

• Arteries

• Haemoglobin
