Answer #1

Answer

- Loop of henle helps to create an osmotic gradient in order to reabsorb more water and produce concentrated urine.

  • The descending limb of the loop is permeable to water and impermeable to ions. It promotes water reabsorption.
  • The ascending limb of the loop is permeable to ions but impermeable to water. It actively pumps sodium ions out of the renal tubule.
  • As the concentration of sodium ions increase in insterstiital fluid, a high osmotic gradient is formed that aids more water reabsorption from the collecting duct.

Imagine two different aberrant kidneys. One has all the extracellular solution throughout the cortex and all of the medulla changed so that it now had an osmolarity of 300 mosm throughout; the other has an osmolarity of 1400 mosm throughout. Imagine that both kidneys are also bathed in high levels of antidiuretic hormone (ADH). Draw a diagram of the nephron indicating and labeling all its parts and show how the osmolarity of the solution in the lumen of the nephron...

Rewrite the function to use a single for Loop. The one-loop implementation and the two-loop implementation shall return the same 2darray. Sample: if X = np.array([[2, 3, 5], [4, 5, 6]]); Y = np.array([[4, 5, 6], [2, 3, 5], [3, 4, 5]]), then euclid_dist(X, Y) returns array([[3., 0, 1.414], [0, 3., 1.732]]). in python program it will return array([[3., 0, 1.414], [0, 3., 1.732]]).
