how does blood run through the human heart?

Answer 1

from the right atrium to the right ventricle to the lungs, back to the left atrium, to the left ventricle, and back to the body

Answer 2

In order!

You can think of the circulatory system as a closed loop of pipes that begin and end at the heart. Blood gets pumped through those pipes by the heart muscle. Blood leaves the heart and goes out to all tissues of the body through the arteries, delivers oxygen and picks up CO2 in the capillaries, and returns to the heart through the veins.

The blood from the veins enters the heart through the right atrium, gets pumped into the right venticle and out to the lungs, where the blood gets oxygenated.

Blood from the lungs returns to the heart through the left atrium, and gets pumped to the left ventricle, and then back out through the arteries.

And this cycle repeats with every heartbeat many times each minute for an entire lifetime.

Answer 3

Deoxygentated blood enters the right atria through the inferior and superior vena cava, as well as the cardiac sinus and travels into the right ventricle. From there, blood flows into the pulmonary arteries to the lungs, where gas exchange occurs and the blood become oxygenated. The blood returns to the left atria through the pulmonary veins. It then passes into the left ventricle, into the aorta and out into the rest of the circulatory system.

Answer 4

Deoxygenated blood arrives to the Right Atrium from the superior and inferior vena cava, flows through thr tricuspid valve into the right ventricle, through the pulmonary semilunar valve to the lungs where it receives oxygen. The oxygenated blood is brought back to the heart by four pulmonary veins into the left atrium, passes through the mitral valve into the left ventricle,which forces the blood through the Aortic valve into the aorta and to the body.

Answer 5

Flow of Blood
Blood from the body flows:

1. to the Superior and Inferior Vena Cava,
2. then to the Right Atrium
3. through the Tricuspid Valve
4. to the Right Ventricle
5. through the Pulmonic Valve
6. to the Pulmonary Artery
7. to the Lungs

The blood picks up oxygen in the lungs, and then flows from the lungs:

1. to the Pulmonary Veins
2. to the Left Atrium
3. through Mitral valve
4. to the Left Ventricle
5. through the Aortic Valve
6. to the Aorta
7. to the body

Answer 6

The pure blood from the lungs enters the heart through the pulmonary veins from the left and right lung into the left auricle/atrium and then it flows down into the left ventricle through the bicuspid/mitral valve and due to the contraction of the ventricular muscles stimulated by the sinoauricular node,it flows into the systemic aorta through the semi lunar valves,it supplies pure blood to all parts of the body
The impure blood is collected by the 2 anterior precaval veins or the anterior vena cava which collects the blood from anterior part of the body and opens into the right auricle/atrium,and the posterior postcaval vein or the inferior vena cava collects impure blood from the posterior parts of the body and opens through the eustachian valve into the right atrium/auricle.it flows into the right ventricle through the tricuspid valve and from the right ventricle it flows into the pulmonary aorta through the semi lunar valves.the pulmonary aorta bifurcates into left and right and goes to the left and right lungs respectively.
The closing of the bicuspid and tricuspid valves produce the LUBB sound and the closing of the semi-lunar valves produce the DUBB sound.

Answer 7

quickly, very very quickly. And in the pathway that pdigoe described.

Answer 8

It is pumped...
