Question

explain the action of Diaphragm in human respiration​

Answer 1

Answer:

$\huge{\star{Role\:of\:Diaphragm\:in\:Respiratory\:System}}\\\\{\Rightarrow{Upon \:inhalation,\: the\: diaphragm\: contracts \:and\: flattens\: and \:the \:chest \:cavity \:enlarges.}}\\{This \:contraction\: creates\: a\: vacuum,\: which \:pulls \:air \:into \:the\: lungs.}\\{Upon \:exhalation, \:the \:diaphragm \:relaxes\: and\: returns\: to\: its\: domelike \:shape}\\{and \:air \:is \:forced \:out \:of \:the \:lungs.}$

Answer 2

Answer:

The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs
