Question

Briefly explain the mechanism of the heart

Answer 1

HEART IS ONE OF THE MOST IMPORTANT PART OF OUR BODY WHICH PUMPS BLOOD TO EVERY PART OF OUR CELL SO IT IS KNOWN A PUMPING ORGAN .

STRUCTURE OF HEART :

HEART IS DIVIDED INTO TWO PARTS:

1) AURICLES

2) VENTRICLES


AURICLES ARE OF TWO TYPES :
LEFT AURICLE AND RIGHT AURICLE

VENTRICLES ARE OF TWO TYPES:
LEFT VENTRICLE AND LEFT AURICLE

BLOOD VESSELS ARE OF 3 TYPES

ARTERIES (TRANSFERS OXYGENATED BLOOD FROM HEART)

VEINS ( TAKES DEOXYGENATED BLOOD FROM OUR BODY )

CAPILLARIES ( A CONNECTION BETWEEN ARTERIES AND VEINS )

AND

BLOOD IS OF TWO TYPES:
OXYGENATED BLOOD (RED)
DEOXYGENATED BLOOD (BLACK)

HOW HEART WORKS :

FIRST OF ALL, RIGHT AURICLE TAKES DEOXYGENATED BLOOD FROM OUR BODY
THROUGH, SUPERIOR VENA CAVA (FROM BRAIN)
AND INFERIOR VENA CAVA (FROM BODY).


THEN,THROUGH VALVES RIGHT AURICLE TRANSFERS ALL THE BLOOD TO RIGHT VENTRICLE AND FROM THERE RIGHT VENTRICLE TAKES AND TRANSFERS OXYGENATED BLOOD FROM LUNGS THROUGH "PULMONARY ARTERY".


FROM PULMONARY ARTERY, BLOOD GOES TO LEFT AURICLE THROUGH PULMONARY VEIN AND LEFT AURICLE MAKES ALL THE BLOOD OXYGENATED AND THROUGH"VALVE"IT GOES TO LEFT VENTRICLE AND FROM THERE THE BLOOD IS READY TO GO TO EVERY CELL AND PART OF OUR BODY THROUGH "AORTA".


AND THIS CYCLE CONTINUES..............



HOPE IT HELPS
