Final Exam Lecture 4 Flashcards
If no Impediment to filtration, the tip of Bowman’s capsule should have the same fluid composition as what?
What was filtered from the Glomerular Capillaries
What organ is the long term BP and pH regulator?
*Short Term pH regulator
Kidney
*Lungs
If your HCT is low, what will the Kidneys release in order to increase RBC production?
EPO
How do the kidneys regulate pH?
Produce Bicarb and rid excess protons
What is an example of nitrogenous compounds in DM2?
Urea
What hormone does the kidney use to regulate osmolarity?
ADH
In order from Large to small, list the Renal Arteries
Renal Artery - Segmental Artery - Interlobar Arteries - Arcuate Arteries - Interlobular Arteries
In order from in to out, list the Renal Veins
Interlobular veins - Arcuate veins - Interlobar Veins - Segmental Veins - Renal Vein
What is the functional unit of the kidney
Nephron
How many nephrons do we have?
*Per each kidney?
2 million
* 1 million each
90-95% of Nephrons are which kind?
*Where do their capillaries dip into?
*Superficial or Deep
Cortical Nephrons [Superficial]
*Outer medulla
5-10% of Nephrons are which kind?
*What are their capillaries called
*Superficial or Deep
Inner Medullary Nephrons
*Vasa Recta
*Deep
In the Vasa Recta, are there more ascending or descending portions?
*Why
More ascending than descending
*b/c it slows blood velocity, which keeps solutes from being washed out in the deep inner medullary interstitium
If ascending vasa recta blood flow is increased, what would happen to inner medullary osmolarity?
It would be decreased, as you are washing out all of the solutes
Which part of the kidney/nephrons is most sensitive to hypotension/ischemia?
Inner medullary Nephrons
