|
Retroperitoneal |
Behind the parietal peritoneum |
|
|
Erythropoiesis |
The production of red blood cells |
|
|
Renal blood flow rate |
The rate at which blood flows through the kidneys |
|
|
Glomerular filtration rate |
The rate at which filtrate is produced in glomerular filtration |
|
|
Tubular maximum |
The maximum rate of reabsorption by active transport through the nephron tubules |
|
|
Buffer system |
A mixture of an acid and a base which resists changes in pH |
|
|
2. Starting with the proximal tubule, order the structures listed below in terms of when they are encountered by filtrate as it travels out of the body |
Proximal tubule, loop of Henle, distal tubule, collecting duct, minor calyx, major calyx, and renal pelvis |
|
|
3. Label the structures pointed out below: |
a) renal corpuscle b) Bowman's capsule c) glomerulus d) descending limb of the loop of Henle e) loop of Henle f) ascending limb of the loop of Henle g) proximal tubule h) distal tubule i) collecting duct |
|
|
4. Which of the structures above change their permeability to water? What causes the change? |
The distal tubule + collecting duct. The amount of ADH present. |
|
|
5. In the drawing below, the arrows indicate the direction in which solutes travel between a capillary and the nephron. Indicate whether each arrow illustrates reabsorption or secretion. |
a) reabsorption b) secretion |
|
|
6. An increase in GCP will do what to GFR? |
Increase GFR |
|
|
7. Two substances are in the filtrate in equal concentration at the proximal tubule and both exceed their T-max concentration. If the reabsoprtion T-max is higher for substance A than substance B, compare the concentrations of A and B in the blood as it leaves the kidney. |
The concentration of A is greater in the blood than B |
|
|
8. What are juxtaglomerular cells and what do they do in the body? |
Cells in the kidney which sense and respond to low blood pressure and low sodium concentration in the blood. They secrete renin |
|
|
9. What is the normal range for the pH of blood? |
7.35 to 7.45 |
|
|
The pH of blood is 7.30. Is the person in acidosis or alkalosis? |
Acidosis |
|
|
11. Describe the three processes which regulate blood pH. Indicate the relative effectiveness of each one as well as the relative speed of each one. |
Buffer systems - least effective, very fast Respiratory system - more effective, a bit slower Secreting H+ in nephron - most effective, slowest |
|
|
12. In the bicarbonate buffer, which substance reacts if an acid is introduced in the blood? |
Bicarbonate |
