The Cardiovascular System

The heart is made up of

• one chamber

• two chambers

• three chambers

• four chambers

The thick muscular wall that separates the left and right side of the heart is called the

• suture

• septum

• superior vena cave

• sternum

Blood that passes through the right side of the heart is known as:

• oxygenated blood

• deoxygenated blood

Blood vessels that transport blood away from the heart are called:

• capillaries

• veins

• thoracic duct

• arteries

Which type of blood vessel contains valves to stop blood from flowing backwards?

• veins

• arteries

• capillaries

• aorta

The superior and inferior vena cava

• carries deoxygenated blood from the body into the right atrium

• carries oxygenated blood from the lungs into the left atrium

• carries oxygenated blood from the left ventricle to the body

• carries deoxygenated blood from the right ventricle to the lungs

Capillaries

• have thick muscular walls to withstand the high pressure of blood that is pumped through them

• have thinner walls and contain valves to prevent the backflow of blood

• are only a single cell thick, which is semi-permeable

• carry blood away from the heart

What is the name of the pigment that gives red blood cells their colour?

• Thrombocytes

• Keratin

• Melanin

• Haemoglobin

The pulmonary vein

• carries deoxygenated blood from the right ventricle to the lungs

• carries oxygenated blood from the lungs into the left ventricle

• carries deoxygenated blood from the body into the right atrium

• carries oxygenated blood from the lungs into the left atrium

What carries oxygenated blood from the left ventricle to the body?

• Aorta

• Pulmonary artery

• Pulmonary vein

• Vena Cava
