PHYSIOLOGY - Cellular physiology: homeostasis; the properties of the plasma membrane; transports (the diffusion, primary and secondary active transport); osmosis. Basic Electrophysiology: membrane potential; action potential; nerve impulse propagation; synapses. Muscle physiology: muscle contraction; electromechanical coupling; relationships between force-length and strength-speed into the muscles; types of motor-neuron units. Cardiovascular system: hemodynamic of circulation; systemic pressure and mechanical properties of blood vessels; adjustment of systolic and diastolic pressure; blood velocity; systemic and pulmonary circulation; the venous system. The heart as a mechanic pump: mechanical work of the heart; cardiac output; self-regulation of cardiac output; regulation of heart rate and electrocardiography. Physiology of the interstitial tissue: exchange of liquid between capillaries and interstitium; the function of the lymph: the volume control of the interstitial fluid. Respiratory system: functional anatomy of the respiratory system; pulmonary ventilation; the ventilation-perfusion mismatch; mechanical properties of the lung and chest wall; the diffusion of gases: the alveolar-capillary units; hemoglobin saturation curve; gas transportation. The kidneys function: functional anatomy of the nephron; the mechanism of glomerular filtration; the renal clearance: filtration function, reabsorption and secretion; proximal tubular functions, Henle's loop functions; sodium and water balance. Digestive system: gastrointestinal motility; gastrointestinal secretions and digestion; absorption of food nutrients and dietary balance.
