Document Summary
Therefore it drinks little water and excretes a lot of it. It replenishes salt through the gills. i. ii. i. excrete dilute urine, salt diffuses out: land - faces dehydration because of water loss through feces, urine, across skin, and from surfaces of gas exchange organs. Each bulb has a tubule cell and a cap cell and a tuft of cilia projecting into the tubule. During filtration, beating of the cilia draws water and solutes from interstitial fluid through the flame bulb, releasing the filtrate into the tubule network, which then moves outward through the tubules and empties as urine. Arteries and veins travel in/out of the glomerulus toward/away from the bowman"s capsule (capillaries). Then salt and water go into the peritubular capillaries. Glucose, amino acids, potassium, and other nutrients are transported into the interstitial fluid. Toxic materials are secreted into the filtrate by the transport epithelium. Secretion of h+ and reabsorption of hco3- ph regulation.
