The respiratory system is a biological system that allows animals and plants to exchange gases. The anatomy and physiology of the respiratory system varies depending on the organism's size, environment, and evolutionary history. The human respiratory system includes the following structures: Nose, Mouth, Pharynx, Larynx, Trachea, Bronchi, Lungs. The lungs are a pair of cone-shaped organs that take up most of the space in the chest. The lungs take in oxygen, which the body's cells need to live and function. The lungs also get rid of carbon dioxide, a waste product of the cells. Here are... Show more The respiratory system is a biological system that allows animals and plants to exchange gases.

The lungs also get rid of carbon dioxide, a waste product of the cells. Here are some other parts of the respiratory system: Trachea Also known as the windpipe, the trachea is a tube that extends from the larynx into the thoracic cavity. The trachea branches to form the right and left main bronchi. Bronchi The trachea divides into two bronchi, each leading to a lung. The bronchi carry air to and from the lungs, and help moisturize the air and screen out foreign particles. Pharynx Also known as the throat, the pharynx is a passageway that extends from the base of the skull to the sixth cervical vertebra. It serves both the respiratory and digestive systems. Larynx The larynx houses the vocal cords, and is located just below where the pharynx splits into the trachea and the esophagus. Show less
