write the function of the heart with labelled diagram

Answer 1

$\huge{\bold{\underline{Answer\: \colon}}}$

$\bold{\underline{ Working \: of \: heart }}$


------------------------------------------------------------------------------------------------------------------


$\bold{\underline{Function \: \colon}}$


1). Pump blood in human body to the different organs.


2). Indirectly through blood heart sent oxygen to the body cells and organs.


3) Heart every time beats non stop called a main part of $\bold{human\:circulatory \: system}$

------------------------------------------------------------------------------------------------------------------

Terms in the working of heart :

$[A]\: The \: blood \: carrying \: oxygen \: is \: known\: as\: \bold{oxygenated\: blood}.$

$[B]\:The \: blood \: having\: no \: oxygen \: is \: known \:as\: \bold{deoxygenated \:blood}.$

------------------------------------------------------------------------------------------------------------------


Step - by - step working pattern of heart :


Note :


$[1] \:\bold{Heart\: beats \: circulate\: the \: blood \: in \: human \: body}.$


$[2]\: \bold{Our\: heart\: is \: \underline{double\: pump}}.$


------------------------------------------------------------------------------------------------------------------


$[3]\: When\: the \: muscles \: of \: \bold{all \: four\: chamber} \\ of \:the \: heart \: are\: relaxed\: , the\: oxygenated\\ blood \: from \: the \: lungs \: into \: the \\ \bold{left \:atrium} of heart.$


$[4]\: The \: \bold{left\: atrium} \: contract\: the \: oxygenated \: blood \: pushed\\ into \: the \: \bold{left\: ventricle} \: through \: the \: valve \: V_1 .$


$[5]\:When\: the \: \bold{left\: ventricle\: contracts} \: , the \: oxygenated \\ blood \: is forced\: into \: the \: \bold{aorta}.$


$[6]\:Then \: main \: artery \: divided \: into \: small \: to \\ the \: different \: \bold{organs}.$


$[7]\: Then \: these \: arteries \: divided \: into\: \bold{capillaries}.$


$[8]\: Then \: it \: will \: transfer \: blood \: with \: oxygen \: \\ to \: the \: various \: \bold{organs}\: of \: the \: body\\ and \: gives \: oxygen \: to \: body \: cell.$


$[9]\:Now \: blood \: \bold{losses} \: oxygen\: and \: change \: into\: \\ \bold{deoxygenated\: blood}.$


$[10]\:The \: deoxygenated \: blood \: carry\: \bold{ CO_2}.$


$[11]\: Then\: transfer \: to \: the \: \bold{ vena\: cava} \: and \: to \\ the \: \bold{right \: atrium} \: of \: the \: heart.$


$[12]\:Now , \: blood \: pushed \: into\: the \: \bold{right \: ventricle}\: through \\ valve \: V_2.$


$[13]\:Then\: the \: blood\: is \: pumped\: into\: \bold{lungs}\: through \\ the \: \bold{pulmonary\: artery}.$


$[14]\:Then \: lungs \: absorbs\: oxygen \: from\: air \: and \: releases \\ it's \: \bold{CO_2}.$


Then blood sent again to the left atrium of heart by pulmonary vein for circulation in body.

It's repeated again and again
