1. Upper Chambers (Atria):
- Right Atrium: Yeh heart ke upper right side mein hota hai. Right atrium oxygen-se-poora blood ko body se receive karta hai jo veins ke through aati hai. Yeh blood fir right ventricle ko bheja jata hai.
- Left Atrium: Yeh heart ke upper left side mein hota hai. Left atrium oxygen-se-bhara blood ko lungs se receive karta hai. Yeh blood phir left ventricle ko bheja jata hai.
2. Lower Chambers (Ventricles):
- Right Ventricle: Yeh right atrium se aayi hui blood ko receive karta hai. Right ventricle se blood lungs ki taraf pump hota hai taaki woh oxygen se bhar jaye.
- Left Ventricle: Yeh left atrium se aayi hui oxygen-se-bhari blood ko receive karta hai. Left ventricle se yeh blood body ke baaki parts ki taraf pump hota hai.
Jab heart beat karta hai, to yeh process kuch is tarah se hota hai:
- Diastole: Heart ke chambers relax hote hain aur blood right aur left atrium mein bhar jati hai.
- Atrial Systole: Atrium contract karte hain aur blood ventricles mein bhej dete hain.
- Ventricular Systole: Ventricles contract karte hain, right ventricle se blood lungs ki taraf aur left ventricle se blood body ke baaki hisson ki taraf pump hota hai.
Yeh chaar chambers ek coordinated way mein kaam karte hain taaki blood ko efficiently pump kiya ja sake. Right side ke chambers (right atrium aur right ventricle) oxygen-se-khaliya blood ko lungs tak bhejte hain, jahan se woh oxygen se bhar jati hai. Phir yeh oxygen-se-bhari blood left side ke chambers (left atrium aur left ventricle) se body ke har hisson tak bheji jati hai.
Yeh cycle lagatar chalta hai aur body ke organs aur tissues ko zaroori oxygen aur nutrients pahuchata hai. Heart ke chambers ka yeh coordination blood circulation ko smooth aur efficient banata hai
