KEY POINT 1 A pH between 0 and 7 is acidic a pH of exactly 7 is neutral a pH between 7 and 14 is basic KEY POINT 2 The more free unattached H ions there are in a solution the more acidic it is KEY POINT 3 HCO3 is a buffer that makes pH less acidic by absorbing H ions in the blood so they re not free anymore KEY POINT 4 The kidneys control the amount of H excretion and amount of HCO3 conservation in the body in order to maintain the pH of the blood 1 If the pH of a system is rising is it becoming more acidic or more basic 2 Does that mean that it has more or less H ions 3 Does that mean that the kidney wants to excrete more or less H ions

Application Diabetic ketoacidosis is a complication of diabetes that occurs when cells cannot take in and use glucose for energy Instead cells break down fat instead of glucose As a result of this shift in metabolism a class of molecules called ketone bodies build up in the blood at a pace faster than the kidneys can compensate for The ketone bodies make the blood more acidic 1 In this situation would the kidneys try to excrete more or less H ions to compensate Why 2 Would the kidneys try to conserve more or less HCO3 to compensate Why

Application Hypertension high blood pressure could possibly be caused by which of the following clinical abnormalities Select all answers that apply a Low renin levels b High renin levels Low aldosterone d High aldosterone

5 Because water behaves this way what is aldosterone s effect on blood volume Why 6 Taking into account how aldosterone affects blood volume what is the effect of aldosterone on blood pressure Why Application Spironolactone is a medication that binds to the same receptor as aldosterone and blocks its action Think about how a coin cannot fit into a slot if the slot is jammed by something else and how this would cause the coin machine to not work Explain why excessively high blood potassium levels are a possible adverse side effect associated with this medication

1 Renin is an enzyme that converts angiotensinogen into angiotensin I It is released in response to low blood pressure 2 Angiotensin I is converted into Angiotensin II by ACE Angiotensin Converting Enzyme 3 Angiotensin II exerts the following physiological effects Binds to smooth muscles surrounding blood vessels causing their diameter to constrict b Causes the release of aldosterone and ADH in ratios that depend on how you want to affect osmolarity of body fluid 1 How would systemic vasoconstriction narrowing the diameter of blood vessels all over the body affect blood pressure Why 2 Would a drug that inhibits ACE these are called ACE inhibitors increase or decrease blood pressure Why ID 62 63

Application When patients are dehydrated doctors administer IV fluids Explain why IV fluids cannot simply be pure water and why they would have to include some salt Remember that there is some salt inside each and every cell

5 When ADH reaches the kidneys does blood volume increase or decrease Why 6 When blood volume is affected in this way does blood pressure increase or decrease Why Application Caffeine inhibits the secretion of ADH from the part of the brain that produces it Explain why caffeine 1 causes people to pee more and 2 become dehydrated

Key points 1 Aldosterone binds to its receptor in the distal convoluted tubule DCT Key point 2 This binding causes the cells in the DCT to make channels that allow for the exchange of sodium Na and potassium K Follow the directions of the arrows to answer the questions below 2 Aldosterone causes Na to move from a The tubule into the blood b The blood into the tubule 3 Aldosterone causes K to move from a The tubule into the blood b The blood into the tubule 4 Water follows 5 Because water behaves this way what is aldosterone s effect on blood volume Why 6 Taking into account how aldosterone affects blood volume what is the effect of aldosterone on blood

Body compartments capillary wall cell membrane plasma ECF interstitial fluid intracelluar fluid ICF ECF extracellular fluid compartment fluid outside cells ICF intracellular fluid compartment fluid inside the cells Interstitial fluid fluid that surrounds the cell Plasma liquid component of blood The line between plasma and interstitial fluid is dotted the cells that line the capillaries are slightly leaky which means that ions can move freely between plasma and the interstitial fluid This results in solute concentration being identical in plasma and interstitial fluid 1 Based on the diagram above and the caption what are the two major compartments in which body Fluids can be found 2 The plasma component of the blood is in which of these compartments 3 In the human body solute concentration in the extracellular fluid influences cell volume How would high salt concentration in this compartment affect cell volume

Efferent arteriole Glomerulus Afferent arteriole KEY S E Bowman s capsule Peritubular capillaries Proximal tubule Filtration blood to lumen Reabsorption lumen to blood Secretion blood to lumen Excretion lumen to external environment Loop of Henle Distal tubule Collecting duct To To bladder and external environment renal vein Application The diagram above shows the peritubular capillaries wrapping around the kidney tubule The exchange of many substances like water occurs between the blood and the lumen of the tubule lumen just means the inside of the tube Use the concept of osmosis to explain what effect eating salty foods would have on blood pressure Hint Think about which direction water would move in if the blood were salty into the tubule from the blood or out of the tubule into the blood and how this would affect blood volume Then think about how blood volume would affect blood pressure

2 The plasma component of the blood is in which of these compartments 3 In the human body solute concentration in the extracellular fluid influences cell volume How would high salt concentration in this compartment affect cell volume 4 Water follows Use the osmosis review to answer this question Application Na is the primary extracellular cation It is what physicians refer to as salt in the body Explain how moving Na from one compartment to another can manipulate osmosis there is another question on the next page

Remember cell walls are semi permeable which means they only allow certain substances to pass through freely For these questions it s not the solute that moves it s the water A way to quickly visually assess the direction of water movement Water follows salt if there s salt on both sides of the semipermeable membrane then water moves toward the side with more salt to balance out the concentration on both sides and make them equal 1 Define osmolarity You can use its mathematical definition or describe what it is in words Describe the net direction of fluid movement in each of the cases above into or out of the cell 1 Hypotonic solution 2 Isotonic solution 3 Hypertonic solution

1 Under what conditions in the blood is ADH released a High solute concentration b Low solute concentration 2 In which direction does water diffuse after ADH is released From the tubule into the blood b From the blood into the tubule 3 How does this movement of water affect the osmolarity of the blood It dilutes the blood b It makes the blood more salty 4 How does this movement of water affect the osmolarity of the urine It dilutes the urine b It makes the urine more concentrated salty
