1)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. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

2)The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.

3)Realdo Columbo (1515–1559) confirmed the pulmonary circulation on vivisection. He also discovered that the heart's four valves permitted flow of blood in one direction only: from the right ventricle to the lungs, back to the left ventricle, and from there to the aorta.

4)William Harvey was born on 1about 45 seconds

Answer: On average, it takes about 45 seconds for blood to circulate from the heart, all around the body, and back to the heart again. An average adult's heart beats more than 100,000 times a day.

5)Your blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.
