List 2 substances that are secreted from our blood

This preview shows page 2 - 3 out of 3 pages.

16. List 2 substances that are secreted from our blood into the convoluted proximal tubule?(i) Uric acid(ii) Organic acid 17. The loop of Henle is all about? 18. In the descending limb of the loop of Henle water is reabsorbed back into our blood. 19. In the ascending limb of the loop of Henle sodium chloride is reabsorbed. 20. In the distal convoluted tubule these 2 substances are reabsorbed: (i) Sodium chloride (ii)Water

21. Our nephrons reabsorb NaCl (salt) and this enables water to be then be reabsorbed. The water moves because it follows the osmotic gradient. 22. In the distal convoluted tubule these 2 ions are secreted from our blood into the filtrate: (i) Potassium (ii) Hydrogen 23. Reabsorption is done mostly by the Proximal tubule Secretion is done mostly by the Proximal tubule Concentration of the filtrate is done mostly by the loop of Henle Fine tuning of the concentrations is done mostly by the Distal tubule 24. One last bit of reabsorption occurs in the collecting duct. List the 3 substances that are reabsorbed:(i) Urea(ii) Sodium chloride (iii) Water 25. List the 6 main components of the filtrate that are excreted.(i) water(ii) Sodium chloride(iii) Potassium(iv) Bicarbonate(v) Creatinine(vi) Urea 26. Which of these six substances is used as a marker for glomerular filtration rate (because it enters the nephron via filtration and is not reabsorbed or secreted)? 27. The rate of water excretion is controlled by two hormones. List these 2 hormones: (i) Aldosterone (ii) ADH Anti-diuretic hormone, also known as Vasopressin.

    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.
