How does a drop of blood move through the body?
How blood circulates in the body. As the heart pumps, blood is pushed through the body through the entire circulatory system. Oxygenated blood is pumped from the heart to the rest of the body, while deoxygenated blood is pumped to the lungs where it is reoxygenated before returning to the heart.
Do veins carry oxygen-rich or oxygen-poor blood?
Arteries (red) carry oxygen and nutrients from your heart to the tissues of your body. Veins (in blue) bring oxygen-poor blood back to the heart. The arteries begin with the aorta, the large artery branching from the heart. They carry oxygen-rich blood from the heart to all the tissues of the body.
What brings the blood back to your heart?
There are three main types of blood vessels. Arteries (red) carry oxygen and nutrients from your heart to the tissues of your body. Veins (in blue) bring oxygen-poor blood back to the heart. The arteries begin with the aorta, the large artery branching from the heart.
Where does blood enter and leave the heart?
Oxygen and carbon dioxide travel to and from tiny air sacs in the lungs, through capillary walls, into the blood. Blood leaves the heart through the pulmonary valve, through the pulmonary artery and into the lungs.
What are the stages of blood flow in the heart?
14 stages of blood flow through the heart. 1 superior vena cava and inferior vena cava. The vena cava is the largest vein in the body that carries oxygen-poor or deoxygenated blood to the right 2 left atrium and the right atrium. 3 Left ventricle and right ventricle. 4 pulmonary arteries and pulmonary veins. 5 Aorta and coronary arteries.
How does the circulatory system of the heart work?
The blood circulatory system (cardiovascular system) supplies nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels that run through the whole body. The arteries carry blood away from the heart; the veins bring it back to the heart.
