Active Learning Assignment #21.Please describe the anatomy of the airway from the glottic opening to the alveoli, and comment on the asymmetry (areas where there are differences in the anatomy on the right and left).2.We discussed oxygen transport, and how it informs our understanding of the importanceof hemoglobin. We also discussed oxidative phosphorylation as the primary means of ATP generation in humans. In the context of that information, why is cardiac output (andtissue perfusion) essential for cellular health?which is then taken up by tissue myoglobin. Thus oxygen, is now available for cells of thebody to use power metabolism through oxidative phosphorylation. 3.Describe clonal selection, and which of the formed elements are important in antibody production.Clonal selection is when bone marrow fives rise to B cells, mature B cells migrate to lymphoid organs, and a mature B cell recognizes epitopes. IgM antibodies are the first antibody to be produced in response to infection.4.What are the functions of the pancreas that make it unique as both an endocrine and exocrine organ?The pancreas is both an endocrine and exocrine organ because the endocrine portion has pancreatic islets that secrete insulin and glucagon. The exocrine portion is 99% of the pancreas that secretes 1200 to 1500 mL of pancreatic juice per day.5.What is a zymogen?Zymogens are digestive enzymes secreted as inactive proteins. They are converted to active enzymes by removing some of their amino acids.
