|
Where are the kidneys located
|
level of T12 and L3
|
|
|
What are the functions of the Kidneys
|
1)maintain homeostatis
2)fluid volume and balance 3)PH balance 4)hormone production 5)urine production a- glomerulus filtration b- tubular reabsorbtion of nutrition and electrolytes c-tubular secretion of waste and toxins |
|
|
What two horones do the kidneys produce
|
Erythropoietin- signals bone marrow to make more red blood cells
Prostaglandins- regulates blood pressure and water retention |
|
|
What are the Ureters
|
A one-way system that leads from the renal pelvis to the bladder
|
|
|
Urinary Bladder
|
1- Micturition (to pee)
2- urine |
|
|
Urethra
|
is the continuation of the neck of the bladder
|
|
|
Difference between the male and female urethra
|
Male is longer and thinner and more prone to blockages. In addition to urine it also carries sperm and seminal fluid during ejaculation.
The Females is shorter and straigher and carries urine only |
|
|
What is a nephron
|
A Kidney cell. Basic funtional unit of the kidney
|
|
|
How many Neprons are found in a med. sized dog kidney
|
about 700k
|
|
|
What are the neprons composed of
|
Renal corpuscle, proximal convoluted tubule and the distal convoluted tubule
|
|
|
What is urine production governed by
|
glomerular fultration, tubular reabsorption and tubular secretion
|
|
|
What is the decide factor of water excretion or retention
|
sodium levels. the higher the sodium the more water is retained- the lower more is excreted
|
|
|
Describe the urinary system process
|
blood enters the glomerulus via the afferent glomerular arteriole to the capallaries which forces plasma into the bowmans capsule where it moves to the proximal convoluted tubule then the loop of henle to the distal convoluted tubule and then the collecting duct- from there is it passed to the ureters and then the bladder
|
|
|
Name two benefits of massage to the urinary system
|
1)Increases urine output
2)promotes excretion of wastes in the urine |
