Major organs involve include the nose and mouth,nasal passages,tranchea,bronchi
(singular:bronchus),lungs,alveoli and diaphragm
Respiratory system has a close relationship with circulatory system,oxygenating blood for tissues to survive and expelling carbon dioxide as waste
alveoli-Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body. Carbon dioxide travels in the blood from the body's tissues and passes through the alveoli to be breathed out.
Bronchi are the main passageway into the lungs. When someone takes a breath through their nose or mouth, the air travels into the larynx.
Trachea or windpipe, is a tube that starts from the end the mouth, upper respiratory system and extends all the way to the bronchial tree. Trachea is the pathway through which the air travels to the lower respiratory system, bronchial tree, lungs, and aveloli. Trachea connects the upper respiratory system to the lower respiratory system.
nasal passage for inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract.
What are bronchioles?
ANSWER
Inside your lungs, tubes split again and again, like the branches of a tree. The smallest of those branches are called bronchioles, and they end in tiny air sacs called alveoli. The alveoli are where the oxygen is picked up by your blood.
