Why is it important that body reabsorbs bicarbonate (HCO3) ions? Excreting too much bicarbonate would cause you to be very acidotic and therefore very ill. 4. How does urine become more concentrated in the Loop of Henle? By reabsorbing water in descending limb which is highly water permeable and then reabsorbing 25% of the filtered sodium chloride in the ascending limb. This means that what we are left with is a higher concentration of waste products 5. What ions are secreted at the distal tubule? Some potassium and hydrogen ions 6. What is reabsorbed in the collecting duct? Some urea, some sodium chloride, and some water. 7. Why is creatinine used as a marker for the glomerular filtration rate? Because creatinine is not reabsorbed or secreted along the nephron. 8. How does aldosterone and ADH control the rate of water excretion? Aldosterone acts on the distal tubules and increase the rate of water reabsorption, and ADH also known as vasopressin which is released from the posterior pituitary and this causes more water to be reabsorbed by the

collecting ducts. Both these hormones act when the body is in a state of under hydration and needs to retain water.

    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.
