Respiration, a vital automatic process crucial for life, is finely regulated through a series of complex mechanisms involving various parts of the nervous system and the respiratory tract. Understanding these mechanisms is essential for comprehending how the body responds to different physiological demands and medical conditions. Regulatory Mechanisms in the Medulla The primary control of […]
Human Respiratory System Respiratory System is an anatomical system that helps in the exchange of gases. We need energy for doing external activities and for carrying out the functions of the internal organs. Energy is released with the help of oxygen present in the air, oxygen reacts with the food and releases energy by a […]
Mechanism of Human Respiration Oxygen is required by the cells for oxidising the food and to release the energy. The cells cannot utilise the oxygen directly. Air is taken into the lungs first and the oxygen present in the air diffuses into the blood and the carbondioxide diffuses out. This part of respiration is called […]
Human Body Our Human Body represents the entire structure of the human organism. It consists of trillions of cells that are organised biologically to form the entire human body. Human body contains different organ systems consisting of various organs. These organ systems are constructed wonderfully to perform various functions. All the organ systems are structurally […]
The contraction of the diaphragm and the inter coastal muscles produces expansion of the chest cavity, so air enters into the lungs during inspiration. A forced inspiration can produce additional expansion, so more air can enter the lungs . Similarly, a forced expiration can expel an extra volume of air. The various respiratory volumes are: […]
