Question

write the working process of heart ?

Answer 1

The heart has four chambers ...i.e left atrium , left ventricle , right atrium and right ventricle . the oxygenated blood from the lungs enters the left atrium through pulmonary vein , it then enters left ventricle. from the left ventricle it passes through the aorta to pump to various parts of the body.

From the various parts of the body the deoxygenated blood is carried by the vena cava to pour into the right atrium and then it passes through the right ventricle and is pumped into the pulmonary artery to the lungs for oxygenation ..

WORKING OF A HUMAN HEART IS VERY EASY TO STUDY WITH A DIAGRAM ... IT IS PROVIDED AS AN ATTACHMENT

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

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.
