Answer:
A. . Blood from the veins enters the ventricles.
C. Atria push blood into the ventricles
Explanation:
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
1. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve.
2.The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.
3. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve.
4. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

Explanation:
Scleroderma- In medical terminology, this is defined as a chronic hardening and tightening of the skin or connective tissues. This is mainly due to the overproduction of collagen (a type of protein) in the tissues. A person with scleroderma experience various symptoms such as<em> cold fingers or toes, small red spots on face and chest, swollen joints, muscle weakness, ulcers on fingertips, etc. </em>
This condition is often considered as mild but there are some cases when it can also lead to a fatal situation. It can cause heart and lung disease. The building up of collagen in the body thickens the tissues in the lungs, which is known as<u> fibrosis. </u>Fibrosis makes it hard for oxygen to be transported into the blood. Scleroderma can also scar the heart tissue. This can cause damage to the heart.
<u>Take note that scleroderma cannot be treated nor cured.</u> The overproduction of collagen cannot be stopped. However, the symptoms that a person experiences can be lessened with medications. This is the reason why the answer is letter b. The nurse needs to correct the patient on this because there is no potential cure for scleroderma.
