Human Respiratory System and it’s Mechanism! The human respiratory system consists of a pair of lungs and a series of air passages leading to the lungs. The entire respiratory tract (passage) consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. Air enters the nose through the nostrils.

Types of respiration present in all living organisms are: 1. Anaerobic Respiration 2. Aerobic Respiration All living organisms require energy to carry out life processes. This energy comes from food. However, processes carried out in cells cannot use the energy locked in stored food, fats, etc., directly. Cellular processes get usable energy from a process called respiration. Respiration commonly involves [...]
