执医记忆（Memory of the medical） The physiological Factors that affect the oxygen - off curve Convert the pH value to [H +] to memory: [H +], pCO2, temperature, 2, 3 - DPG up, So were going to move the oxygen to the right. Aeration/blood flow ratio memory Blood - the river into the alveolar oxygen - people of red blood cells in the blood - manned - that is, when the ship ventilation/blood flow ratio increase oxygen, blood flow is relatively less, as: water is the ship, less people cross the endless means to take a boat (oxygen), blood flow to () the river dry ship (RBC) less, cant all reach the destination, cannot perform the normal physiological function, like pulmonary dysfunction. The ratio of ventilation to blood flow is reduced by an hour, which means that the ventilation is insufficient and the blood flow is relatively more abundant. Also cannot perform normal physiological function, can be seen in lobule pneumonia, pulmonary real change and so on. Features of microcirculation: Low, slow, big, change; Influencing venous reflux factors: Blood volume, body position, three pumps (heart, respiration, skeletal muscle); General characteristics of hormones: No tube, target, small amount, high efficiency; The metabolism of glucocorticoid: Raise sugar, egg, grease; The physiological role of aldosterone: Keep sodium, water, potassium, etc. The vegetative nerve can regulate the internal organs Sympathetic heart rate, blood pressure rise sweat, The pupil dilated and the gastrointestinal peristalsis was suppressed. The secondary excited heart rate, the bronchial narrow gland secretion, The pupil constrictor the gastrointestinal tract and can relax the sphincter Electrical activity characteristics and mechanisms of ventricular myocytes 01234 sodium potassium calcium potassium source, internal and external pumps Explanation: the ventricular muscle action potential is divided into five periods (except that) Phase 1, 2, 3, 4 (complex phase), 0 sodium Internal flow, 1 potassium outf
