What is the flow of a drop of blood through the heart, it’s structures, and the vessels from the right atrium to the right hand and back?
1 Answer
rt atrium to rt ventricle to pulmonary artery to capillaries to pulmonary vein to left atrium to left ventricle to aorta to arteries to capillaries to veins to rt atrium
Explanation:
Oxygen poor blood from the bodies cells travel to the right atrium. The heart beats and the blood is pumped into right ventricle. The right ventricle a larger heart chamber pumps the blood into the pulmonary artery. This is the only artery with Oxygen poor blood.
The pulmonary artery carries the blood to the lungs. In the lungs the blood moves into capillaries where Carbon Dioxide is released from the blood and the Oxygen is absorbed into the blood.
The capillaries now rich in Oxygen passes into the pulmonary veins .The pulmonary veins carry the blood to the left atrium. The blood is pumped into the left ventricle. The left ventricle is a very strong muscle that pumps blood into the aorta. The aorta is the largest artery. The blood then flows under pressure to smaller arteries. These arteries carry blood into the capillaries in the body that pass near the cells. Oxygen is released into the cells for cellular respiration and Carbon dioxide is absorbed. The capillaries carry blood to the veins that carry the blood back to right atrium
