The Respiratory System

Respiratory system includes all the organs and tissues associated with the exchange of gas between the animals and its environment leading to the release of energy. This system is responsible for the gaseous exchange. The components of this system are trachea and lungs. Trachea branches to two bronchi which divide into bronchioles which all terminate in small sack-like alveoli. The lungs consist of the bronchioles, alveoli and blood vessels. The blood carries oxygen away from the lungs to the tissues and carbon (iv) oxide from tissues back to the lungs. Gaseous exchange takes place around the alveoli. The entrance to the trachea is guided by the epiglottis which permits only air to pass through. Anatomy, Physiology and Reproduction of Farm Animals - Respiratory system
