Anatomy and Physiology
| Question | Answer |
|---|---|
| The ability to control micturition is often lost after a stroke, Alzheimer's disease, or other CNS problems affecting the cerebral cortex or hypothalamus? True or False | True |
| Inflammation of the urinary bladder lining, usually from infection is called? | Cystitis |
| Which vessels form the plexus that supplies the proximal and distal convoluted tubules? | Peritubular capillaries |
| Blood enters the glomerulus by the: | Afferent arteriole |
| Blood exits the glomerulus by the: | Efferent arteriole |
| This structure filters the fluid out of the blood: | glomerulus |
| This capsule collects the fluid filtered out of the glomerulus: | Bowman's |
| Name the two segments within the loop of Henle: | Descending and Ascending |
| The location where blood vessels, nerves, and the ureter enter and leave the kidney is the: | Hilum |
| The portion of the nephron in charge of making urine is the: | Renal tubule |
| Most sodium is reabsorbed from the glomerular filtrate in the: | Proximal convoluted tubule |
| Which of the following substances should not be found in urine? | Glucose |
| A triangular-shaped smooth area on the floor of the bladder is called: | Trigone |
| Many diuretics work by blocking tubular reabsorption of: | Sodium |
| This calyx collects urine leaving the papilla: | minor calyx |
| Two to three minor calyx join together to form a | major calyx |
| The kidney region that is the site for urine production: | Renal cortex |
| The kidney region that is the site for urine collection: | Renal medulla |
| These extensions extend from the renal cortex and divide the interior region into cone-shaped sections: | renal columns |
| The point of the pyramid is called: | renal papilla |
| The renal corpuscle consists of what two structures | glomerulus and Bowman's capsule |
| The juxtaglomerular cells response to a drop in blood pressure and decreased blood volume. What enzyme is released? | renin |
| Renin converts inactive plasma protein ______________ made in what organ,into what? | angiotensinogen, liver, angiotensin I |
| Angiotensin I via the circulatory system goes to the__________ where it is converted into __________________, by what enzyme? | lungs, angiotensin II, angiotensin-converting enzyme (ACE). |
| The adrenal glands are stimulated by what to secrete what? | Angiotensin II, aldosterone |
| What hormone causes the DCT to retain Na+ and this in-turn causes an increase in what & other events? | aldosterone, water retention and increase in blood volume in-turn increases your BP :-) |
| What always follows Na+? | chloride and water |
| What does Antidiuretic hormone(ADH)do that the end result is decrease urine volume and increase in blood volume. | permability to the DCT & collecting duct to water goes into the peritubular capillaries |
| The atrial natriuretic peptide is secreted when BP increases which in-turn causes what? That the end result is DCT excretes more Na+Cl- and water reducing blood volume and BP | inhibits secretion of aldosterone and ADH. |
| The wall of the bladder is called the: | detrusor muscle |
