Most Upvoted Answer
Diffrenciate between inhalation and exhalation?
Inhalation
Inhalation is the process of taking air into the lungs. It is a crucial part of the respiratory cycle and involves several key components:
  • Diaphragm Movement: During inhalation, the diaphragm contracts and moves downward, creating a vacuum that pulls air into the lungs.
  • Chest Expansion: The rib cage expands as the intercostal muscles contract, further increasing the volume of the thoracic cavity.
  • Airflow: Fresh oxygen-rich air enters through the nose or mouth, travels down the trachea, and fills the alveoli in the lungs.
  • Oxygen Exchange: Oxygen from the inhaled air diffuses into the bloodstream, while carbon dioxide is transported from the blood into the alveoli.

Exhalation
Exhalation is the process of expelling air from the lungs. This occurs after inhalation and also involves specific mechanisms:
  • Diaphragm Relaxation: The diaphragm relaxes and moves back to its dome shape, reducing the volume of the thoracic cavity.
  • Chest Contraction: The intercostal muscles also relax, allowing the rib cage to move inward and downward.
  • Airflow: The air, rich in carbon dioxide, is pushed out of the lungs and expelled through the nose or mouth.
  • Carbon Dioxide Removal: This process removes carbon dioxide from the body, maintaining acid-base balance in the blood.

Summary
Inhalation and exhalation are fundamental processes of respiration. Inhalation brings oxygen into the body, while exhalation removes carbon dioxide. Together, they ensure the efficient functioning of the respiratory system, allowing for essential gas exchange.
