Urinary System-Advance Anatomy & Physiology

I've added some comments in the quoted text that should point you in right direction. Of course it has been 30+ years since I took A&P, so you should review the information in your text.

So we recently had a substitute teacher for my college course and it was horrible!!! He taught us stuff we really didn't need to know and I was so confused and currently teaching myself the whole lesson I am stumped on a few questions to my homework, if anyone knows the answer, please tell me mine are wrong and correct me because I don't want to get the wrong information to study for the test! I have like 7 pages of homework! I did look up online and my book doesn't teach us crap.
1) From filtrate formed about 148(females)/180 (Males) liters/day of fluid are reabsorbed. This is about _____% of the glomerular filtrate. The total amount of urine eliminated from the kidneys daily is usually about _____liters/quarts.
----is it 82% and 2 Liters? I don't get what they are saying.
I think they are asking about glomerular filtration rate. Of the blood that is pumped every minute by the heart, about 20% enters the kidney to be filtered. Most of that fluid is returned to the body. Only a small amount is excreted as urine. What % of the fluid is reabsorbed? How much is typically excreted?
They tell you that in females 148L per day is reabsorbed. In males 180L per day is reabsorbed.
You know that only about 1-2L are excreted. That should tell you the total amount of fluid that is filtered each day -
148L reabsorbed + 1-2L excreted = total fluid filtered
That should tell you what % of the fluid is reabsorbed
amount reabsorbed / total fluid filtered = % that is reabsorbed/B]
2)If you sat down and ate a complete 5 pound box of candy you would likely result in a urinary condition called ______?
-----Diabetes mellitus?
3) ______re]sults from left side heart failure?
-----Failure of left ventricle?
4)Blood in most capillaries of the body flow into vessels called _______, but blood in glomerular capillaries flows into ________?
----Arteries and bowman's capsule?
I think you are not seeing the important word in the question. I've underlined it. Does blood flow FROM capillaries INTO arteries?
5) Blood pressure in glomerular capillaries is about 55mm Hg. Which is ____that in other capillaries in the body is about ______mm Hg
-----Less and 120/80
6) The total amount of urine eliminated from the kidneys daily is usually about ______liters/quarts. (This amount is highly variable)
----2 liters/quarts?
7) When blood pressure drops ________cells of the kidney release ____which ultimately catalyzes the formation of ______. This substance _______blood pressure by vasoconstriction and indirectly stimulates the release of ______from the adrenal cortex.
-----Juxtaglomerular, Renin, afferent arterioles, increase, aldosterone
8) Acidosis/alkalosis imbalance problems are most effectively regulated by the ______, but take longer to eliminate the imbalance. Quick responses occur in the _____, by removing carbon dioxide, and in the _____by removing H+
-----The first one I got bicarbonates but the rest I can't think of the names
Acid-Base Regulation - Endocrine and Metabolic Disorders - Merck Manuals Professional Edition
9) Reabsorption of ______is the key in the regulation of fluid and electrolyte homeostasis.
-----ANP
10) Sodium (The Na+ in salt) is very hard to get rid of because ADH is produced almost continuously to reabsorb sodium in the kidney tubules. To GET RID of sodium, the body must produce ____, which decreases the reabsorption of sodium and thus allows more of it (and water) to end up in urine.
----I thought of vasopressin....but that is what ADH is....
11) Diabetes ____refers to "Sugar diabetes" caused by a "malfunction" in the pancreas, while diabetes _______refers to "water diabetes" caused by a "malfunction" in the posterior pituitary gland.
----Mellitus, pancreas, insipidus, posterior pituitary gland
12) WHen you are thirsty the viscosity of the blood becomes thicker and this is detected by the thirst center in the _____. To return the viscosity of your blood back to homeostasis takes probably 12-30 mins for water to be absorbed and actually affect the blood's viscosity. But we do not drink for 12-30 minutes until this happens. Our thirst is satisfied by:
1) Relieving the dryness in our ____and ____
2) Stretching out the ______
-----Mouth, skin.....and I am not sure what its stressing....a layer of some sort?
