Bowman’s capsule glomerulus proximal tubule (cortex) (medulla) thin descending limb of loop of henle loop of Henle thin ascending limb of loop of Henle thick ascending limb of loop of Henle (medulla) (cortex) distal tubule collecting duct c. Blood supply i. Afferent arteriole Glomerulus in Bowman’s capsule efferent arteriole peritubular capillary along proximal/distal tubule Vasa recta (down loop of Henle) venule vein II. Urine- purpose of kidney a. Glomerulus i. Filtration- where blood filtrates ii. Bowman’s space- starling equation 1. Increase K, and Pc 2. Glucose, water, water solubles, small proteins, amino acids, urea 3. Small peptides cross ok 4. Large proteins- cross poorly 5. RBC- don't cross iii. Glomeluar filtration rate (GFR) 1. ~125 mL/min 2. fairly constant- even with change in BP 3. overall a. filtrate like plasma- isoosmotic to plasma b. few proteins iv. Reabsorption- filtrate to blood v. Secretion- blood to filtrate b. Proximal tubule i. Reabsorbs 1. 100% of glucose and proteins, amino acids- don't want to pee out 2. 70% of water and electrolytes 3. 50% of urea ii.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
