Answer 1

Answer: (A), (B)

The correct options are

B The cardiac muscles do not contract in a coordinated manner rhythmically.

Human heart basically has 3 vessels that enter the heart and 2 vessels that leave the heart.

The vessels that enter the heart are:

* Anterior Vena Cava - Brings deoxygenated blood from upper part of the body to the heart.

* Posterior Vena Cava - Brings deoxygenated blood from the lower part of the body to the heart.

* Pulmonary Vein - Brings oxygenated blood from the lungs to the heart.

The vessels that leave the heart are:

* Pulmonary Artery - Carries deoxygenated blood to the lungs for oxygenation.

* Aorta - Carries oxygenated blood to all parts of the body.
