Name the process by which the fluid passes from the glomerulus into the renal tubule
ultrafiltration
1 of 7
One difference and one similarity between the processes of excretion and secretion
Excretion produces a metabolic waste product and secretion a useful product. They both are a part in homeostasis.
2 of 7
Name the tissue that lines the proximal convoluted tubule
Epithelial

Explain the relationship between the length of the loop of Henle and the water potential of urine
The longer the loop of Henle, the lower the water potential of the urine because ions pass from the ascending limb into the medulla, creating a low water potential in the medulla. More water is therefore reabsorbed from the collecting duct by osmosis

Why protein in the urine is often a symptom of chronic high blood pressure
High blood pressure in the glomerulus forces proteins through the fenestrations in the capillaries and damages them. They then are forced through and damages the basement membrane which no longer acts as a filter.

Proteins and DNA

Suggest how the kidney of a mammal living in the desert is adapted to reduce the volume of urine produced
Loop of Henle is very long to create a low water potential in the medulla and high concentration gradient. The collecting duct is more permeable to water due to having more aquaporins so more water diffuses out by osmosis (more sensitive to ADH)
