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.

What returns blood to heart?
The veins return blood from the body back to the heart, then out of the heart to the lungs where it is oxygenated, then back to the heart and carried back out into the body by arteries. The blood in the veins is blue but is seen through you skin as a dark green.
What chambers of the heart pushes blood out?
The ventricles. These are the two lower chambers, one on each side. The ride ventricle pushes blood to the lungs, for oxygenation and the left ventricle pumps the oxygenated blood through the body.
How many compartments does the heart have?
The heart is divided into 4 chambers: 2 on the right hand side and 2 on the left. Each upper chamber is known as an atrium and each lower chamber as a ventricle. The 4 compartments are known as: the right atrium; the right ventricle; the left atrium and the left ventricle.
How many areas ia your heart made up of?
The heart is made up of four different blood-filled areas, and each of these areas is called a chamber. There are two chambers on each side of the heart. One chamber is on the top and one chamber is on the bottom. The two chambers on top are called the atria (say: ay-tree-uh). If you're talking only about one, call it an atrium. The atria are the chambers that fill with the blood returning to the heart from the body and lungs. The heart has a left atrium and a right atrium.The two chambers on the bottom are called the ventricles(say: ven-trih-kulz). The heart has a left ventricle and a right ventricle. Their job is to squirt out the blood to the body and lungs. Running down the middle of the heart is a thick wall of muscle called the septum (say: sep-tum). The septum's job is to separate the left side and the right side of the heart.The atria and ventricles work as a team - the atria fill with blood, then dump it into the ventricles. The ventricles then squeeze, pumping blood out of the heart. While the ventricles are squeezing, the atria refill and get ready for the next contraction. So when the blood gets pumped, how does it know which way to go?Well, your blood relies on four special valves inside the heart. A valve lets something in and keeps it there by closing - think of walking through a door. The door shuts behind you and keeps you from going backward.Two of the heart valves are the mitral (say: my-trul) valve and the tricuspid (say: try-kus-pid) valve. They let blood flow from the atria to the ventricles. The other two are called the aortic(say: ay-or-tik) valve and pulmonary (say: pul-muh-ner-ee) valve, and they're in charge of controlling the flow as the blood leaves the heart. These valves all work to keep the blood flowing forward. They open up to let the blood move ahead, then they close quickly to keep the blood from flowing backward.
What does the function of the heart valves?
Heart valves control the flow of blood into, out of, and within the chambers of the heart. The main function is to let blood flow in one direction only, ensuring that blood does not flow backwards.
Why cant the heart have only two chambers either than four?
Because each chamber has its own function, the blood goes somewhere else from each chamber.
Between the chambers of the heart are?
Between each chamber of the heart, there is one of two things, depending on the relationship of the chambers. If blood flows from one chamber to the other, there is a 1-way valve preventing backup. If blood never goes from one chamber to another, ie, the left ventricle and the right ventricle, then there is a layer of tissue blocking passage of blood from one chamber to the other.
What type of blood in each chamber of the heart?
The bloody kind
Anterooms of the heart?
Atriums? Right Atrium Left atrium Ventricles Right Ventricle Left Ventricle These are chambers is the heart with valves that pump blood into each chamber
What keeps the blood from flowing back into a chamber of the heart?
A specific chamber? It's valves and each one has a different name. I'll list the chamber and the valve which stops 'backflow':- Right Atrium: Tricuspid valve Right Ventricle: Pulmonary valve Left Atrium: Mitral valve Left Ventricle: Aortic valve The valves basically open when the relevant chamber is pumped but when pressure goes back towards the chamber they snap shut, stopping blood from going back through the heart/circulatory system.
What returns blood to heart?
The veins return blood from the body back to the heart, then out of the heart to the lungs where it is oxygenated, then back to the heart and carried back out into the body by arteries. The blood in the veins is blue but is seen through you skin as a dark green.
What is the difference between the atria and the ventricles of the heart?
The atria are the two upper chambers in the heart, and they receive blood entering from outside of the heart. The ventricles are the two lower chambers of the heart and they each receive blood from an atrium and then send it out of the heart.
How many chambers does each type of vertebrae have in there heart?
The heart of fish have two chambers. The heart of reptiles and amphibians have three chambers. The heart of mammals have four chambers.
On each side of the heart a value allows blood to travel from the upper chamber to the lower chamber why is this important?
It is important because if the blood stayed in the upper chamber forever there can become a major problem with your body
What chambers of the heart pushes blood out?
The ventricles. These are the two lower chambers, one on each side. The ride ventricle pushes blood to the lungs, for oxygenation and the left ventricle pumps the oxygenated blood through the body.
The heart is made of muscle and has 4 chambers two on each side the left side contains mostly what kind of blood?
Oxygenated blood,
How the blood circulates through the hearts?
The heart contracts and expands due to it's muscles. The blood is made to go one way only, by the use of Valves between each chamber. Blood circulates through the heart in arteries and veins. They pass through various valves and chambers. Because the heart itself is an automatic pumping machine (or a muscle) the blood is pumped into different organs of the body via the bloodstream.
