Question

working of heart in detail for class 10

Answer 1

with the help of upper venacava from (upper parts of the body)

and lower venacava from lower parts of the body the deoxygnated blood from all the parts of the body reaches the right atrium and then flows into the right ventricle. from here than with the help of pulmonary atrey the blood reaches the lungs where exchange of gases takes place and the blood gets the oxygen.from the lungs the blood reaches the heart via pulmonary vein. the blood enters the left atrium and then the left ventricle

then with the help of aorta the oxygynated blood reaches all parts of the body.

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

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.
