Transport system in animals (10)

Pumps blood to lungs then to left side of heart.

Pumps blood to rest of the body which returns to right side of the heart.

Arteries that supply blood to the heart muscle.

Carries deoxygenated blood to the right lung.

Receives deoxygenated blood from the head and body.

Prevent the backflow of blood into ventricle.

Receives deoxygenated blood from the inferior and superior vena cavae.

Prevents backflow of blood into right atrium.

Receives deoxygenated blood from lower body and organs.

Pumps deoxygenated blood to lungs.

Double-walled membrane that surrounds heart.

Separates the ventricle.

Contracts and relaxes to maintain the rhythmical contractions of the heart.

Pumps blood from the left atrium to the aorta.

Serve as attachment for the tendinous chords.

Allow the valves to open and close.

Prevents the backflow of blood into the left atrium.

Carry oxygenated blood from the lungs to the left atrium.

Receives oxygenated blood from the lungs.

Carries deoxygenated blood to left lung.

Carries oxygenated blood to the head and body.

Arteries, capillaries, veins.

Carry blood away from heart to the organs. High blood pressure: small lumen and thick muscular walls maintain the blood pressure that comes from the heart. Elastic to withstand high blood pressure. Muscular walls to create a pulse and to maintain blood pressure. Rarely contain valves only at base of aorta and pulmonary artery (semi-lunar).

Carry blood away from the organs back to the heart. Low blood pressure: the large lumen and thin muscular walls accommodate the blood under low pressure. Not elastic. Very little muscle as blood pressure is low. Contain valves to control direction of blood flow.
