The blood reaches the lungs where it will be package with oxygen. This now oxygen and glucose rich blood with leave the lungs on its way back to the heart by the pulmonary veins.

Coronary artery bypass surgery‚ also coronary artery bypass graft (CABG‚ pronounced "cabbage") surgery‚ and colloquially heart bypass orbypass surgery is a surgical procedure performed to relieve angina and reduce the risk of death from coronary artery disease. Arteries or veins from elsewhere in the patient ’s body are grafted to the coronary arteries to bypass atherosclerotic narrowings and improve the blood supply to the coronary circulation supplying the myocardium (heart muscle).

After goes through those valves‚ it then goes through the lungs‚ and the lungs turn the blood into red‚ thus stating that it contains oxygen. Pass the lungs‚ and then into the pulmonary vein‚ and the left atrium and onto the left ventricle. From the left ventricle‚ it goes though the aorta and arteries‚ and then into the arterioles. After passing through the arterioles‚ it goes into the capillaries

Questions Circulatory Compare and contrast veins and arteries in blood traveling to or from the heart and containing oxygenated or deoxygenated blood (and the exception). The arteries job is to take oxygenated blood and transport if to the other organs and cells of the body‚ away from the heart. Then the veins carry deoxygenated blood back to the heart from the organs. The two exceptions to this is the pulmonary arteries and veins. The pulmonary arteries take deoxygenated blood and delivers it to

Tube 12-7-15 Anatomy Cardiovascular System The Cardiovasuclar system is one of the most important systems in your body and it is also one of the largest systems in your body. This system consists of the heart‚ and a system of vessels called arteries‚ veins and capillaries. They are responsible for transporting‚ nutrients hormones‚ oxygen and waste throughout the body. All of these play an important part in this system and the system would fall apart if one wasn’t there. This system is is powered

Alright folks lets get started with our tour by getting a better understanding of our starting point! We are located in the femoral vein in the right leg. The femoral vein is right next to the femoral artery‚ which is by the femur. The femur is a large bone located in your thigh. This vein has a large blood supply which pumps at a fast speed

through the vana cava (vein) returning the deoxygenated blood from the upper part and the lower parts of the body to the heart. This large veins lead into the right atrium where the pumping heart forces the red blood cells through the tricuspid valve into the right ventricle. The valve stops blood from flowing backwards into the right atrium once it’s in the right ventricle they are then pumped through the pulmonary valve into the pulmonary artery and on to the lungs. The arteries carry blood away from

bladder‚ urethra and renal vessels which include the renal artery and the renal vein. The main blood supply comes from the renal artery which passes from the abdominal aorta into the kidneys. Each artery divides into small branches within the kidney tissues. The blood leaves kidneys via the renal vein. Kidneys We have two kidneys of which are bean shaped and dark red in colour. The ureter and renal vein both emerge from the kidney and the renal artery enters the kidney at the hilum. There is a capsule of
