Question

how do the human heart work

Answer 1

the right Atrium receives deoxygenated impure blood from various parts of body by large when that is vena cava the left Atrium receives oxygenated blood from lungs by pulmonary veins both the atria contract at the same time and the Cuspid valves open up the blood from left Atrium comes in the left ventricle and from right Atrium into the right ventricle both the Atria relax and ventricles contract the cuspid valves are Slam shut and semilunar valves open up the oxygenated blood from left ventricle is formed into outer and is distributed to all the body parts bhaiya trees in the deoxygenated blood from right ventricle is formed into pulmonary out and transported to lungs by the pulmonary arteries for oxygenation.

$\large\textbf{\underline{HERE\:IS\:YOUR\:ANSWER}}$

The heart is a muscular organ. It has different chambers to prevent the mixing of Oxygenated and De-oxygenated blood. The blood containing carbon dioxide has to reach the lungs to remove carbon dioxide and the oxygenated blood from the lungs has to brought back to the heart and then pumped to the rest of the body.

$\underline{Different\: parts\: of\: heart\:are:-}$

⏩ Left Atrium

⏩ Left Ventricle.

⏩ Right Atrium.

⏩ Right Ventricle.

⏩ Pulmonary arteries.

⏩ Pulmonary veins.

⏩ Upper Vena Cava.

⏩ Lower Vena Cava.

⏩ Septum.

⏩ Aorta.

$\huge\mathfrak{Working \:of \:heart}$

⭕️ Oxygenated blood from the lungs comes to the thin walled upper chamber of the heart on the left, the left atrium.

⭕️ The left atrium relaxed when it is collecting this blood. It then contrast, while the next chamber, the left ventricle, expands, so that the blood is transferred to it.

⭕️ When the muscular left ventricle contracts in its turn, the blood is pumped out to the body.

✔️ De-oxygenated blood comes from the body to the upper chamber on the right, the right atrium, as it expands.

✔️ As the right atrium contracts, the ventricle collects the blood.

✔️ Then this blood it pumped into the lungs for oxygenation.

✔️ Then it is brought back to heart and then pumped to the rest of the body.
