Organ Systems 3) Urinary Flashcards
6 Functions of the kidney
1) Excretion - filter blood to remove toxins and ions
2) Regulation of blood volume and pressure
3) regulation of solute level of the blood
4) Regulation of excrecellular fluid PH; by secreting H+
5) Controll rate of cell production
f) regulation of vit D levels
What hormone stimulates the producion of red blood cells?
a) Erythroprotein
What structure filters blood?
Glomerulus
Where is water and solutes reabsorbed?
- Proximal convoluted tubule
- descending Loop of Henle
Where are salts reabsorbed?
ascending Loop of Henle
What happends in the Distal Convoluted Tubule and Collecting Duct.?
More water and salts are reabsorebd hormone depedent
What is the system controlling blood pressure called?
The Renin-Angiotensin-Aldosterone mechanism
What is produced when blood pressure falls?
Renin
Describe the The Renin-Angiotensin-Aldosterone mechanis
Renin turns angiotensun into angiotensin 1
ACE turns angiotensin I in to angiotensin II
Angiotensin ii is a vasoconstrictor so blood pressure rises
Angiotensin ii causes a release of Aldosterone w
causes a reduction in urine production so blood pressure can rise
What is another name for the anti duoretic hormone?
Vasopressin
Where is vasopressin produced and in response to what?
- In the pituitary gland
- Reduced blood pressure
What does vasopressin do?
acts upon ghe distal conbeluted tuble and collecting duct to increase reabsorbtion of water and NA
- Reduces urinne and increases blood pressure
