About this document
Respiratory System Flow Chart for Class 10 by Alina Ather is a document available to read on EtoBox.
The human respiratory system allows for gas exchange between the lungs and blood. Air enters through the nasal cavity where it is warmed and filtered before moving to the pharynx and trachea into the lungs. In the lungs, air moves through branching bronchioles until reaching tiny air sacs called alveoli. Oxygen from the alveoli passes into blood vessels and carbon dioxide passes from the blood into the alveoli to be exhaled. Breathing is driven by muscles that expand and contract the rib cage and diaphragm
