Answer:

FALSE

Explanation:

Papillary muscles are found in the bottom chambers of the heart and attaches to the tricuspid  and bicuspid valve through tendons to facilitate blood flow during systole. It also prevent prolapse. These muscles contract before the contraction of ventricular muscles (or before the contraction of ventricles) by pulling chordae tendinae till the ventricles are relaxed. This helps in preparing the valves for high ventricular pressure

Hence, the given statement is false

Answer:

1. Aorta

2. Left atrium

3. Right ventricle

4. The pulmonary artery

5. Left ventricle.

Explanation:

The aorta is the main artery of the body that carries the oxygen-rich blood to all the body parts except the lungs from the left ventricle. It is divided into main coronary arteries or blood vessels.

The left atrium is one of the heart chambers, it is located in the upper part of the heart on the right side that receives the oxygenated blood from the lungs through the pulmonary vein.

The right ventricle is the chamber of the heart that pumps the deoxygenated blood to the pulmonary valve to MPA to the lungs to get oxygenated.

The pulmonary artery or the main PA (MPA) carries the oxygen-depleted blood from the right ventricle into the lungs, where blood becomes oxygenated.

The Left ventricle is the thickest muscle chamber of the heart responsible for the pumping oxygen-rich blood to the circulatory system and to the body through the aorta.
