Cardiovascular system

The 3 main components of the cardiovascular system are

• Lungs, heart, veins

• Lungs, heart, blood vessels

• Blood Vessels, heart, blood

• Blood, plasma, heart

------ circulation carries away deoxygenated blood from the body and returns back oxygenated blood to the <3

The heart structure contains

• 5 chambers

• 3 chambers

• 2 chambers

• 4 chambers

There are three layers of the heart wall (outer to inner)

• Epicardium, endocardium, myocardium

• Epicardium, myocardium, endocardium

• Myocardium, epicardium, endocardium

• Endocardium, myocardium, epicardium

The aorta is the body's most important

The ----- valve separates the left atrium from the left ventricle.

• Tricuspid

• Pulmonary

• Aortic

• Mitral

Choose the correct one

• Veins have less pressure and can hold more blood than arteries.

• The walls of arteries are thinner than veins walls.

• Arteries have less pressure and can hold more blood than veins.

• The walls of veins are thinner than artery walls.

The 4 blood main components are

• Erythrocytes, Leukocytes, Lymphocytes and Platelets

• Plasma, Leukocytes, Platelets, White blood cells

• Red blood cells, Platelets, Erythrocytes, Lymphocytes

• Plasma, Erythrocytes, Platelets, White blood cells

These cells have no nucleus, which means they can easily change shape as they move through the body’s arteries and veins.

• Leukocytes

• Prokaryotic

• Red Blood cells

• Plasma

The functions of the blood are

• Maintains body temperature and chemical balance

• Hydrated our skin and bones

• Transports Nutrients absorbed by the GI tract

• Delivers O2 throughout the body
