ANSC 3080 Lecture Notes - Lecture 21: Rib Cage, Defensin, Muscle Tissue
Document Summary
Move o2 from air to pulmonary blood. Lungs receive 95% cardiac output from rv. Filter blood (get toxic out of the blood such as alcohol since it is volatile), chemical processing, maintenance (regulate ph) and defenses (part of first line of defence) Interchanges of gases between atm and the cells of the body that uses o2. Transport of air to and from the lungs. O2/co2 exchange between the air in the lungs and cells in the body. Oxidation of cellular molecules that produces co2, water and atp. Ventilation: movement of bulk airflow, deliver air to the respiratory zone (alveoli) where exchange occurs. Lung diffusion: o2 and co2 movement in and out between alveoli and blood vessels. Circulation: between blood and tissues (refer to individual gas molecules) Require adequate function of the pulmonary and systemic circulation. Tissue diffusion: between rbc and tissue cells = passive diffusion (refer to individual gas molecules) Internal respiration: metabolism using o2 and producing co2.
