BIOC33H3 Lecture Notes - Lecture 14: Mucin, Abdominal Wall, Elastin
Document Summary
We are talking about pulmonary ventilation last time we talk about airway resistance we got to how we can regulate broncho constriction and dilation. Another disease asthma - not unlike cystic fibrosis excess production of mucous restricts the capacity for air to get through respiratory tract excess mucous production. How did we end up with constricted bronchiole filled with mucous and swelling that cause asthma - Which makes asthma that kind of disease it is over reacting to situation normal reaction would be fine over reaction too much. The muscular part of chest wall is made up of intercostal muscles which are muscles that lie in between the ribs as well as the diaphragm (not shown) occupies dome space at floor of thoracic cavity. The other structural component important when we are thinking about pressure difference generation by the respiratory system is the plural membranes and plural cavity.
