BIOD 151 MODULE 2 EXAM FROM EXPERT Respiratory Rate (RR) - the number of breaths taken in one minute determines MV Minute Volume (MV) - the total volume or amount of air breathed in 1 minute Emphysema - disease in which the alveoli are damaged. inner walls of alveoli become week and rupture, causing a loss of alveolar ventilation ability and loss of total gas exchange because of the loss of alveoli often caused by smoking cystic fibrosis - A genetic disorder that is present at birth and affects both the respiratory and digestive systems. causes epithelial cells to produce mucus w/o enough saline. mucous gets too thick and clogs resp tract. Auscultation - listening to sounds within the body (usually with a stethoscope) pulmonary edema - accumulation of fluid in the lungs caused by several diseases such as infections, cancers, and congestive heart diseases crackle sounds b/c fluid filled alveoli "pop" open with each breath pleurisy (pleuritis) - inflammation of the pleura due to infection, cancer, or injury pleural space fills with air, pus, blood, other fluids etc sharp pain when breathing b/c layers rub together causing friction Bronchi - the branches located at the lower end of the trachea that carry air into the lungs. the two main ones enter left and right lungs they further divide what happens as bronchial tubes divide and subdivide - they get thinner and the cartilaginous rings aren't present two main (primary) bronchi - divides into lobar (secondary) bronchi lobar (secondary) bronchi - 3 on the right and 2 on the left each supplying one lung lobe divides into tertiary bronchi and are then bronchioles when at 1mm diameter Bronchioles - Airways in the lungs that lead from the bronchi to the alveoli interface b/w conducting and respiratory portions of system terminal bronchioles - smallest air conducting bronchioles
