a

HEART - Double circulation process

hello guys this issue around here and I

warmly welcome you all if you guys

remember in the last lecture I have

explained the structure of heart all

these four chambers blood vessels valves

and so for everything now today I'm

going to make you understand

the function of heart means the double

circulation process with this heart

expands the deoxygenated blood from all

the different parts and organs of the

body comes to the right atrium through

inferior vena cava and superior vena

cava

then this deoxygenated blood is passed

to the right ventricle through tricuspid

vaults okay first of all let me make you

clear with the mechanism of this walls

then this heart expands this tricuspid

valve open ups simultaneously this

pulmonary valve closes and when this

heart contracts this tricuspid valve

closes and simultaneously the pulmonary

valve open ups okay when the heart

expands the deoxygenated blood comes to

the right edge film through inferior and

superior vena cava and then it is passed

to the right ventricle through tricuspid

walls and when then this heart contracts

this like a speed vault closes and the

pulmonary vault open apps and the

deoxygenated blood is passed to the

lungs through this pulmonary artery in

the lungs this deoxygenated blood

releases carbon dioxide into the alveoli

and simultaneously absorbs oxygen to get

oxygenated and when again the heart

expands the oxygenated blood from the

lungs comes to the left atrium of the

heart through pulmonary vein and this

oxygenated blood is passed to the left

ventricle through bicuspid wall or

mitral valve as it is labeled here say

here also when the heart expands the

bicuspid or mitral open apps and chaotic

valve closes and when the heart

contracts this chaotic valve open

and mitral valve closes similarly

similar as we have seen in the left

chamber or sorry right chambers so when

the oxygenated blood from the lungs

comes to the left atrium and passes to

the left ventricle through bicuspid

valve or mitral valve and when then this

heart contracts second time this

oxygenated blood through this chaotic

vault passes to the different parts and

organs of the body through aorta yota is

the largest artery of the body it's

another it's another name is truncus

arteriosus so that's all about double

circulation process this process is

called double circulation because the

blood from the parts of the body comes

to the heart twice first in the right

chambers then in the left chambers

that's why it is called double

circulation it is circulated twice in

the heart so that's all about double

circulation process see you guys in the

next video have a nice day
