State And give one function each of five organs of respiratory system in humans
1) Nose: The nose filters, warms, and moistens the air we breathe in before it reaches the lungs. It also contains olfactory receptors that help us to smell.
2) Lungs: The primary function of the lungs is to facilitate the exchange of oxygen and carbon dioxide between the inhaled air and the bloodstream. The lungs oxygenate the blood while removing waste gases (carbon dioxide) from it.
3) Trachea: The trachea, also known as the windpipe, serves as a pathway for air to travel from the nose and mouth to the lungs. It is composed of cartilage rings which keep it open and prevents its collapse.
4) Bronchi: The bronchi are the two main branches that extend from the trachea and lead to the lungs. Their function is to divide the airflow into smaller bronchioles, allowing air to reach different regions of the lungs.
5) Diaphragm: The diaphragm is a dome-shaped muscle located beneath the lungs. It contracts and relaxes during inhalation and exhalation, aiding in the expansion and contraction of the chest cavity to facilitate breathing.
