What is the flow of the blood as it enters until it leaves the heart?

Dexoygenated blood being brought back to the heart from the body via veins enters the superior or inferior vena cava (largest vein) which empties into the right atrium, it passes through the tricuspid valve into the right ventricle, it then passes through the pulmonary valve into the pulmonary trunk to the left and right pulmonary arteries which carries blood to the left and right lungs where blood picks up oxygen and drops off carbon dioxide, it then returns through the right and left pulmonary veins into the left atrium then it passes through the bicuspid valve into the left ventricle, then passes through the aortic valve into the aorta and back to the rest of the body through arteries

The blood always flows through the blood vessels in a certain way and how does the blood flow through the blood vessels once it leaves the heart?
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.
A nutrient is considered to be outside the body until it enters?
the blood or lymph system..... (:
What is blood circuit?
The blood circuit is the totalising of all the veins, aortas and capillaries in the body, through which the blood is pumped by the heart. The oxygenate blood is pumped by the heart until it reaches the capillaries where the blood switches to veins and comes back to the heart again.
What processes take place during the period after the blood enters the kidneys till the urine leaves the body?
Blood flows to the kidney through the renal artery. Once in the kidney the blood flows through a series of smaller and smaller arteries until it gets to the glomerulus. The glomerulus filters blood and to be very simplistic creates a filtrate of the blood or "urine". This urine then flows through a series of progressively bigger tubules and ducts until it gets to the renal pelvis. At this point urine exits the kidney, it enters the ureter (long tube connecting kidney and bladder), and flows into the bladder where it is held until one desires to urinate. At this time urine flows out of the bladder and into the urethra. The urethra connects the bladder to the outside of the body.
What blood vessels carry blood back to the heart?
The blood vessels that carry blood back to the heart are called veins.(Blood does not return to the heart until it passes through the spleen, where dead blood cells go.)
What are the parts found at the left of the heart and right of the heart?
In the right side of the heart, there are the superior and inferior vena cavas. They bring deoxygenated blood from the rest of the body to the heart. The deoxygenated blood enters the right atrium of the heart and is pumped to the right ventricle. They are chambers which temporarily stores blood until they are pumped out. In between the two is the tricuspid valve which prevents the backflow of blood from the ventricle to the atrium when the ventricle contracts. When the ventricle contracts, blood is then forced out the semi-lunar valves and into the pulmonary artery, which is also on the left of the heart. In the left of the heart, there is the pulmonary vein, which brings oxygenated blood from the lungs to the heart (the left atrium) . The left atrium and the left ventricle are chambers as well. The bicuspid valve in between the two act like the tricuspid valve in the other side of the heart. When the left ventricle contracts, blood is forced out the semi lunar valves and into the aorta, through which blood is pumped out of the heart and around the body. In between the left and the right sides of the heart there is the septum, which separates the chambers of the heart and prevents the mixing of blood in the heart, which may lead to inefficiency of oxygen transport.
What do blood vessels have to prevent blood flowing backwards?
Blood vessels cant flow backwards because there is other blood forcing it to move forward. This is propelled by the heart, which is like a pump, and pushes blood around the body until it reaches the heart again. The only way blood could flow backwards was if the heart stopped.
What is the process by which oxygen enters the blood in the lung and leaves it in the body tissues?
Oxygen enters the lungs through inhalation. It is transfered through the thin alveolar tissue to the red blood cells of the pulmonary arteries through an intricate diffusion process. More specifically, the oxygen is bound by the hemoglobin contained within the RBC's. This oxygenated (red) blood is circulated throughout the body until it reaches the capillaries. Tissue is then supplied oxygen by a process called perfusion, the unloading of the oxygen bound within hemoglobin to the surrounding cells. The deoxygenated blood is returned back to the heart for a new cycle. The oxygen is to be used in oxidative phosphorylation (the creation of cellular energy) to continue healthy tissue function
What are the similarities between the circulatory system and a circuit?
The pulmonary circulation is the portion of the cardiovascular system which carries oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated blood back to the heart while for the systemic circulation, it is the portion of the cardiovascular system which carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart... :D
What happens to a piece of lean meat from it enters your mouth until the amino acids it contains enter your blood stream?
as it enters the mouth it is broken down by mechenical digestion. then with the aid of the tounge it is pushed down into the oesophagus to the sttomach where it is furthur broken down chemiclly and mixeed with hydrochloric acid. it then leaves as a semi liquid substance into the small intestine where it is soluable it is absorbed. the waste is taken into the large intestine and gotton rid of
What are the 4 chambers of the heart and where does the blood go from each chamber?
The heart is split into two sides; the left and the right.The right side deals with all of the deoxygenated blood coming in from the rest of the body, from the head, lungs, and other organs.The Vena Cava carries the blood into the right side of the heart (or what is otherwise known as the right ventricle) from the body. This blood is then pumped through a small valve (to prevent back-flow*) into another smaller chamber, and then the Pulmonary Artery pumps this blood to the lungs where oxygen is then put back into the blood.This now oxygenated blood enters the left ventricle of the heart via the Pulmonary Vein. This blood passes through another valve (also to prevent back-flow*) and into the 4th chamber. The Aorta (Another artery) then pumps this oxygenated blood from this chamber and around the body. This blood will eventually enter through the Vena Cava again and the process is repeated.Note: Although arteries are defined as blood vessels containing oxygenated blood and veins deoxygenated, when the heart is involved these are simply reversed until the blood enters the Aorta.*If back-flow wasn't prevented then all the blood would be fighting itself. It would basically be like trying to keep a river flowing with another river heading in the opposite direction.
Where does blood go when it leaves the capillaries?
Renal vein It is not renal vein. It is venules. renal vein is only at one point of the body, were talking capillaries; which are all over the body.
