The urinary system includes: |
1 bladder 1 urethra 2 uterers 2 kidneys |
|
|
The indented area on the medial side of the kidney is |
The hilus |
|
|
The basic functional unit of the kidney is |
Nephron |
|
|
Tubular reabsorption and secretion occurs here |
Peritubular capillaries |
|
|
The blood in this vein contains the least amount of waste in the body |
Renal |
|
|
The blood pressure in the glomerular capillaries is _____ than the aorta |
Lower |
|
|
What helps cause the transfer of plasma out of the glomerular capillaries? |
High blood pressure |
|
|
Insufficient production of ADH by the P pituitary can result in |
Polyuria |
|
|
Aldosterone causes reabsorption of _____ in the DCT |
Na |
|
|
The urinary bladder is lined with |
Transitional epithelial cells |
|
|
An animal that is house trained has learned to control: |
The muscle sphincter around the neck of the urinary bladder |
|
|
In the male, the urethra has a reproductive function |
True |
|
|
This route removes nearly all the soluble waste products from blood and transports them out of the body |
Urinary system |
|
|
Which animals have an os penis? |
Dog Walrus Racoon |
|
|
The kidneys of these animals have a multipyramidal or multilobar appearance |
Pigs |
|
|
This part of the nephron descends into the medulla and returns to the cortex |
Loop of henle |
|
|
Na cotransport incolves the movement of amino acids and ______ from the tubular lumen into epithelial cells on the same protein |
Glucose |
|
|
What percentage of amino acids and glucose in the tubular filtrate are reabsorbed in the PCT? |
100% |
|
|
What percentage of all tubular reabsorption occurs in the PCT? |
65% |
|
|
Fenestrations in the epithelium of the DCT allow protein to be reabsorbed |
False |
|
|
There is a significant pressure difference between the fluid in bowmans capsule and in the renal pelvis |
True |
|
|
Reabsorption of Na in the DCT influences water to flow out of the tubular filtrate into the blood |
True |
|
|
Urea in blood is measured as blood urea nitrogen BUN |
True |
|
|
This is composed of the glomerulus and bowmans capsule |
Renal corpuscle |
|
|
These propel urine from the renal pelvis to the bladder |
Urethra |
|
|
This structure carries urine from the urinary bladder to the urethra |
Ureters |
|
|
This blood vessel enters the kidney at the hilus |
Renal artery |
|
|
These act as funnels that direct fluid into the renal pelvis |
Calyces |
|
|
The fluid that is filtered out of blood |
Glomerular filtrate |
|
|
The removal of excess water from plasma in the form of urine |
Diuresis |
|
|
Urine volume is regulated by ADH and |
Aldosterone |
|
|
This hormone acts on the DCT and collecting ducts to promote water reabsorption |
ADH |
|
|
This action moves urine through the uterers |
Peristalsis |
|
|
The production of little urine |
Oliguria |
|
|
This ion is reabsorbed in the ascending part of the loop of henle and the DCT in exchange for K, H, or NH3 |
Na |
|
|
This part of the kidney is lined with transitional epithelium |
Renal pelvis |
|
|
This part of the kidney is lined with cuboidal epithelial cells with brush border |
PCT |
|
|
Most tubular secretion occurs here |
DCT |
|
|
This is the process of transferring substances from peritubular capillaries to interstitial fluid to tubular epithelial cells to the tubular filtrate |
Secretion |
|
|
Oxygen transfer to cells of the nephron takes place here |
Peritubular capillaries |
|
|
The process by which glucose and amino acids enter epithelial cells of the PCT |
Sodium cotransport |
|
|
These play an important role in urine volume and are the primary site of action of ADH |
Collecting ducts |
