Human ventilation such as Pulmonary ventilation, alveolar ventilation and machine ventilation is one of the biggest factors of the human body. Without ventilation which is breathing human life would not exist.. Pulmonary Ventilation is commonly known as breathing. It is the process of airflow into the lungs. Alveolar Ventilation refers to the amount of gases that reaches the alveoli during a breath. Inspiration and expiration, during each cycle a volume of gases moves in and out of the respiratory tract of the ventilation machine. The act of respiration is an automatic process that allows for oxygen to be gained into red blood cells, through diffusion via either passive or active transport. through diffusion via either passive or active …show more content…
The volume measured during either cycle is called tidal volume. To achieve ventilation the respiratory muscles have to generate change in pressure so that gas will flow on, in or out of the Lungs. The respiratory system is everything that exist between the pressure measured at the airway opening and the pressure measured at the body surface.(Kacmarek, 2017)
Respiration and ventilation
The difference between respiration and ventilation. When your diaphragm flattens and your breath. The act of respiration is an automatic process that allows for oxygen to be gained into red blood cells, through diffusion via either passive or active transport the physical movement or pulling or pushing air throughout the body is breathing/ventilation. Air in lungs need to be refreshed always. When breathing you are ventilating your lungs. Air fills the lungs due to pressure within the thoracic cavity, containing the lungs less then automatic pressure. When you exhale, the internal intercostals muscles contracts movement which moves the ribs down and in. Ai. (Kacmarek, 2017) Air exits the lungs because the pressure within the thoracic cavity, containing the lungs, is greater than the atmospheric pressure. Air continues to flow until the pressure inside the lungs drops to the atmospheric

(Boulton. J) (2010) Branching off the tracheobronchial tree increases the cross-sectional area of each airways generated as gas moves from the mouth to the Alveoli, the combined cross-sectional area of the airway increases exponentially. Turbulent flow predominates in the mouth, trachea, and the primary bronchi gas velocity is higher in the bigger airways. As you move deeper into the lung segments, the airways branch into smaller, but more airways and more cross-sectional
