What is the function of each atrium?

Answer 1

the main or central room of an ancient roman house open to the sky with a pool for collecting water.

A large open space in a building

Microscopic air sacs within the lungs

An anatomical structure within the heart

Atrium of the ventricular system of the brain (a cavity or passage in the brain)

Answer 2

The atria are the two upper chambers of the heart (the ventricles are the lower two)

The atria are the 'filling' chambers, so blood entering the heart passes through the atria first, which then push it down into the ventricles.

The two largest veins in the body (the superior and inferior venae cavae) empty deoxygenated blood returning from the body into the right atrium. The right atrium then contracts, pushing the blood into the right ventricle. The right ventricle then pumps the deoxygenated blood to the lungs where it is oxygenated.

After leaving the lungs, the newly oxygenated blood is returned via the pulmonary veins into the left atrium. The left atrium then contracts and pushes the blood into the left ventricle, which pumps the oxygenated blood around the rest of the body.

Answer 3

In the human heart atriums are used to store blood briefly between

beats. This blood is then pumped into the heart's two ventricles, and from there it travels to the body and lungs.

Answer 4

its location is in the upper heart chamber that is smaller than a ventricle.

Answer 5

Right atrium-receives Oxygen poor blood

Left atrium- receives oxygen rich blood

Right ventricles- sends oxygen poor to lung

Left ventricle-sends oxygen rich blood to body

Answer 6

To receive blood from veins and to make sure that the blood moves in only one direction, which is to the ventricle.

Answer 7

the heart
