Document Summary
Dr. p. bryant chase"s oice hours: friday 12:30-2:30pm. Physiology - the science of biological funcions funcion is closely related to structure: to study physiology, we looked at atoms and ions, cells, issues, organs, and organ systems that make up and organism. Changes in physiology associated with diseases (geneic. Pathophysiology mutaions, infecions, environmental factors, etc. : helps understand disease mechanisms, response to disease, ind treatments/ cures, and understand people we know. Biomedical research is helping us to understand normal and pathophysiology, with beneits for individuals, families, and society. Blood part of the circulatory system connects issues and cells in the body. Blood composiion: cells i. red blood cells (erythrocytes) specialized to transport o2, bi-concave shape: short difusion distance for o2. Cytoskeleton: o2 transport: bound to hemoglobin (hb) protein called spectrin maintain the shape (frame) protein) and myoglobin (not, myoglobin binds 1 oxygen molecule while hemoglobin binds 4 oxygen molecules cooperaively.
