Inspiration/ inhalation is the first half of the respiratory cycle where breath is drawn. Several muscles in the respiratory system contribute to the process of inhalation. However‚ the diaphragm and the external and internal intercostals are the primary muscles of inhalation. The diaphragm originates at ribs 7 through 12‚ the xiphoid process‚ and the first 3 lumbar vertebrae. The diaphragm inserts on its’ central tendon which it pulls down and forwards through contraction in order to increase the

constancy of alveolar gas tensions. Firstly it is important to understand what the anatomical dead space and FRC actually are. The anatomical dead space refers to the gas in the conducting areas of the respiratory system where air does not come into contact with alveoli. Examples of places in the respiratory system where anatomical dead space is present are the mouth and trachea. The functional residual capacity is the amount of air that remains in the lungs after a normal and passive expiration. It is usually

process where oxygen diffuses into the body or bloodstream and carbon dioxide diffuses out of the body or blood stream. This process is different for Humans‚ Fish. Frogs and Insects. Humans: In humans the gas exchange system is known as the Respiratory system. The respiratory surface is the Alveoli located on Bronchial tubes inside of the lungs. The average human adult has about 600 million alveoli which comes together to form a surface area of over 100 metres squared. There is only 2 thin walls
