Describe what happens during the following stages in urine forma-tion in the mammalian nephron: filtration, tubular reabsorption, tubular secretion.
Please define/describe the following 3 renal functions in mammals: filtration, reabsorption and secretion. Describe at least one location in the nephron where each of these functions takes place. How does each of these functions contribute to homeostasis of the organism?
Compare and contrast ion and water balance in animals that use protonephridia, metanephridia, and kidneys. Which of the 6 functions of a vertebrate kidney are accomplished by each, and how do they achieve these functions?

- Although the kidneys are probably best known as filtration organs, tubular reabsorption (the second step of urine formation in a nephron) actually reclaims molecules that have already been filtered from the blood. Describe the tubular reabsorption process, including the structures and molecules involved, and explain why these molecules need to be reabsorbed. please helparrow_forwardThe fluids deep in the medulla of the kidney have a much highersolute concentration than those in the cortex.
