Answer 1

Answer:

1. In the heart, there are valves that prevent backwards flow of the blood. The Tricuspid and Bicuspid valve prevent backwards flow of the blood in atria and ventricles.
2. Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
3. The universal blood type is O negative (O-). Donors with type O- blood have the unique power to help anyone in need of a blood transfusion. Red blood cells from O- donors can be transfused to anyone, regardless of the person's blood type.

AB positive blood type is known as the “universal recipient” because AB positive patients can receive red blood cells from all blood types.
