What are the three ways PH is regulated in the body? - correct answer ? How do the kidneys function to combat acidosis? - correct answer ? Describe the equation for net filtration pressure? - correct answer Describe the pressures that drive and reduce the glomerular filtration rate? - correct answer net filtration pressure drives it. How does blood flow to the following region the body? Brain, skin, kidney, Gi and skeletal muscle - correct answer ? Once feedback comes into action, what happens to feedforward? - correct answer ? Why is tubular reabsorption important for the body? - correct answer bring nutrients back to the body. What is insensible water loss? - correct answer ? Describe the trend cellular and paracellular routs that molecules take during tubular reabsorption? - correct answer transcellular means it is going through the cell via membrane transporters on the apical side of the cell, then they will get pumped out by membrane transporters of the lateral side of the cell. paracellular route have leaky cell junctions (also counts of reabsorption.) What is the range of osmolarity in the renal medulla and what is an osmolarity gradient? - correct answer ? shows passive movement of water from descending limb to vasa recta and in reading concentration of filtrate to 1200 mOsm but fluid in vasa recta 280? - correct answer ? Describe how plasma leaves the glomerulus to enter the glomerular capsule? - correct answer plasma leaves through openings of capillaries, podocyte legs (slide 6 kidney function) Which energy substrate is favored in a resting state vs. maximal exercise intensity? - correct answer carbohydrates and fats, fats are favored in resting, maximals exercise carbohydrates Describe how hydrogen ions are buffered in the blood with bicarbonate ions - correct answer ? Steeper part of the work intensity and cardiac output graph is because both SV and HR increase, but after 40% vow max just hr increase, so its less steep? - correct answer Yes Why is lactic threshold a good estimator for marathon finish times? - correct answer no good reason, it happens to corolate with marathon finish times How does mean arterial pressure change with work intensity - correct answer it barely changes What two substructures make up the renal corpuscle? - correct answer glomerous and glomerus capsule( bowmans capsule) What substrcutes make - correct answer procumal tubule, nevron loop Myogenic and tubuloglomerular feedback and where they occur - correct answer (slide 15 kidney) two forms of autoregulators: myogenic mechanism and tubuloglomerular mechanism for GFR
