The human respiratory system is responsible for the exchange of oxygen and carbon dioxide between the body and the environment. It primarily consists of the lungs, trachea, and diaphragm, which work together to facilitate breathing. Air is inhaled through the trachea, where it then travels into the lungs, where oxygen is absorbed into the bloodstream and carbon dioxide is expelled. The diaphragm plays a crucial role by contracting and relaxing to create the pressure changes necessary for airflow in and out of the lungs.

The human respiratory system helps us breathe by taking in oxygen and getting rid of carbon dioxide. It includes important organs like the lungs, trachea, and diaphragm. When we inhale, air goes through the trachea and into the lungs, where our blood picks up oxygen and gets rid of carbon dioxide. The diaphragm is essential because it moves up and down to help pull air in and push it out of our lungs.
