The blood pressure is usually high when blood leaves the small arteries and enters the capillaries.
The blood pressure is usually high when blood leaves the small arteries and enters the capillaries.
The arteries are connected to the veins through capillaries. Blood leaves the heart through arteries, goes throughout the body, then by way of capillaries to the veins and returns to the heart.
The systemic arteriole, then the capillaries, the venule, the vein, the vena cava, the heart, the pulmonary artery, the pulmonary arterioles, capillaries, the pulmonary veins, the heart, into the aorta, and back into the artery.
After blood leaves the arteries, it enters smaller blood vessels called arterioles which help supply the body with blood and then they break down into even smaller vessels called capillaries which then carry the oxygenated blood to the tissues, organs and all cells of the body. Then after the body uses up all the oxygen, the blood becomes deoxygenated which then enters venules and then veins which lead up back to the vena cava of the heart. It then enters the right atrium then passes through the tricuspid valve and then enters the right ventricle, then leaves the heart via the pulmonary artery which enters the lungs to oxygenate the blood.
carbon dioxide
It enters the arteries.
Yes, capillaries form a network around the alveoli. It is through the alveolar walls and into the capillaries that oxygen enters the blood stream. Carbon dioxide leaves the blood by the reverse route.
Aorta--> Arteries--> Arterioles--> Capillaries--> venuoles--> Veins--> Vena Cava--> right atrium--> right ventricle--> pulmonary arteries--> pulmonary veins--> left atrium--> back to left ventricle
blood, at first it is deoxygenated but by the time it leaves the lungs it is full of dissolved oxygen
More fluid leaves the capillaries than returns.
It always flows the same way. It leaves the heart through the Aorta. This is the largest artery in the body. The blood then branches off into progressively smaller arteries until it gets to the tissues. It enters the capillaries at the cell level and then moves into the veins. The reverse process then happens where the blood enters progressively larger arteries until it gets back to the heart where it starts the journey all over again.
Carbron Dioxide/Oygen ExchangeThe oxygen gas molecules enter the alveoli (air sacs) in the lungs. Carbon dioxide leaves the blood in the capillaries and enters the sacs, changing form from solution to gas, while oxygen moves into the capillaries, changing form from gas to solution.Into the Red Blood CellsMost of the oxgyen is picked up by the hemoglobin in red blood cells for transport. The blood carries the oxygenated blood through the pulmonary arteries to the heart.Out to the BodyAs the heart beats, the oxygenated blood flows out of the heart through the aorta and into arteries throughout the body.Into the TissueThe oxygenated blood flows from large arteries to smaller arterioles and into capillaries that nourish cells of the tissues.Oxygen/Carbon Dioxide ExchangeOxygen leaves the capillaries and flows into the cells. At the same time, carbon dioxide leaves the cells and enters the venous capillaries to return to the lungs.FunctionOxygen provides the fuel that allows the cells to carry out their functions.
