How does the heart work
Answers
Your heart is a specialised muscle that pumps blood around your body. Blood carries oxygen and nourishment to all parts of your body and carries waste products to several organs, notably your lungs and kidneys to eliminate.
Your heart is divided into two pumps which work together. Blood coming back from the organs and tissues of your body enters the right side of your heart which then pumps it to your lungs. Your lungs remove waste carbon dioxide from the blood and recharge it with oxygen.
The oxygen-rich blood returning from your lungs enters the left side of your heart, which then pumps it to all parts of your body, including your heart muscle itself.
This process ensures that there is always enough oxygen and nourishment for your body to work efficiently.
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.

⭕️ 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.
