What dose the left atrium do?

Answer 1

Left Auricle and AtriumEach auricle slightly increase the capacity of an atrium so it can hold greater volume of blood.

Answer 2

It is the intake for deoxygenated blood, via the superior and inferior vena cava (huge veins), from all of the body other than the lungs. It pumps into the the right ventricle, which in turn pumps the blood via the pulmonary artery (the only artery without O2) to the lungs to get reoxygenated.

Answer 3

The function of the left atrium is to pass oxygenated blood from the pulmonary veins into the left ventricle.
The function of the atrium is to force the last bit of blood into the main pumping chamber (ventricle) before the power stroke to increase the efficiency of pumping.

The function of the left atrium is to receive blood from the right and left pulmonary veins and conduct that blood into the left ventricle.
The function of the left atrium is to pass oxygenated blood from the pulmonary veins into the left ventricle... i think?? that's my answer :)
It receives oxygenated blood from the pulmonary veins, and pumps it into the left ventricle, via the mitral valve. Atria facilitate circulation primarily by allowing uninterrupted venous flow to the heart, preventing the inertia of interrupted venous flow that would otherwise occur at each ventricular systole

Answer 4

The heart is made of four chambers. The top is the atrium, divided into two parts (left and right). The bottom are the ventricles, also divided into two parts (left and right).

So, the left atrium would be the left top compartment of the heart.

Answer 5

The oxygenated blood that came from the lungs enters the left atrium. After the systole of the left atrium the blood flows into the left ventricle, and from there into the aorta and throughout the body.

So, their role is to supply the body with oxygenated blood.

The left atrium and ventricle are sometimes called "the left heart", and the right atrium and ventricle "the right heart".

The right heart pushes the blood into the lungs circulatory system where the blood is being oxygenated, after which the blood goes to the left atrium etc.

Answer 6

It fills the left Ventricle with oxygenated blood

Answer 7

the purpose of the right atrium of the heart is to pull the none oxiginated (or blue) blood into the heart and pump it into the right ventrical

Answer 8

The left atrium is the upper chamber of the left side of the heart. It receives blood from the pulmonary vein and pumps it into the left ventricle.

Answer 9

carrys blood

Answer 10

Pumps blood into the left ventricle
