Aorta--> Arteries--> Arterioles--> Capillaries--> venuoles--> Veins--> Vena Cava--> right atrium--> right ventricle--> pulmonary arteries--> pulmonary veins--> left atrium--> back to left ventricle
The blood in the atria moves into the ventricles through the atrioventricular valves (tricuspid valve in the right atrium and mitral valve in the left atrium). From the ventricles, the blood is pumped out through the semilunar valves into the pulmonary artery from the right ventricle and the aorta from the left ventricle to circulate throughout the body.
Systematic circulation in frogs occurs eve though they only possess a single ventricle. Arterial blood is returned by the pulmonary veins and only slightly gets mixed with their venous blood. The mixed blood is passed through systemic arches while the head region is supplied with pure arterial blood through the carotid vessels. The highest levels of venomous blood is sent through the pulmo-cutaneous vessels to the lungs and skin of frogs.
Both! Blood enters the atria (upper chambers) on both sides of the heart at the same time. Blood from the body, carrying carbon dioxide, enters the right atrium. Blood from the lungs, carrying oxygen, enters the left atrium. The two atria contract together, pumping the blood into the two ventricles (lower chambers). The ventricles then contract, pumping blood out of the heart. Blood from the right ventricle goes to the lungs, where it loses its carbon dioxide and picks up oxygen. It then goes to the left atrium. Blood from the left ventricle goes to the body, where it delivers oxygen and picks up carbon dioxide. See: http://www.bbc.co.uk/science/humanbody/body/factfiles/heart/heart.shtml
the blood entering the right atrium is deoxygenated blood returning to the heart from the rest of the body. from there it goes to the right ventricle into the lungs where it picks up oxygen. from the lungs it enters the left atrium then into the left ventricle. the left ventricle then pumps the blood through the aorta and into the body.
The chordae tendinae in the left ventricle act as festoons and when left ventricle contracts,these help to close the mitral valve(bicuspid vale) which is between the left atrium and left ventricle.If these chordae are damaged then the closure of this valve is not perfect fit and the blood can regurgitate into the left atrium while the left ventricle is contracting.this is called mitral incompetence.This all depends on the severity of the damage.
left ventricle
blood leaves the left ventricle through what blood vessel
After blood leaves the left ventricle, it goes through the aortic valve to be pumped throughout the body.
After blood leaves the left atrium, it flows into the left ventricle through the mitral valve. From the left ventricle, the blood is then pumped into the aorta, the main artery of the body, which distributes oxygenated blood to all parts of the body.
The left Ventricle pumps blood out to your body
The left ventricle receives oxygenated blood from the left atrium. Blood flows from the left atrium through the mitral valve into the left ventricle, which then pumps the blood out into the aorta to supply the body.
right ventricle
the pulmonary vein bring oxygenated blood from the lungs into the left atrium, where it is pumped into left ventricle, ad up and our through the aorta to around the body. But NO is the answer to your question, it enters into the left atrium, and leaves the heart to go to eh body from the ventricle
arteries
Oxygenated blood passes through the left ventricle of the heart. After being enriched with oxygen in the lungs, the blood returns to the heart and enters the left atrium, from which it flows into the left ventricle. The left ventricle then pumps the oxygenated blood out to the rest of the body through the aorta.
Lung
The aortic valve allows the blood to leave the left ventricle.
