Question

Hello, I am unsure of this question. Can someone please help me? Please explain the flow chart as well, just so I can understand what the flow chart means.

Write a flowchart that describes the path that a molecule of urea takes from its entry into the renal artery to its arrival in the collecting duct.

Answer 1

the glomerulus is the nephron's cup shaped Bowmans Capsule surrounds a knot of blood capillaries .more quantity of the bloods fluid filters into the glomerulus due to high pressure from the circulatory system.the things that are Left behind are large proteins and whole cells, which are too large to fit through. This filtrate is then passed through the nephron tubule. which has 4 main parts ( loop of Henle, proximal convoluted tubule, distal convoluted tubule, and the collecting duct).
In the proximal convoluted tubule, a small amount of resorbtion occurs. Small proteins, glucose, and ions are returned to the blood by active transport. Negatively charged ions follow passively, followed by the process of osmosis of water. About 75% of the filtrate is returned in this section of nephron.
The loop of Henle, lie in the medulla of the kidney, the other parts of the nephron lie outside of the medulla in the cortex. Salt is actively transported out of the filtrate, and since this area impermeable to water, water cannot follow the ions out here.
The distal convoluted tubule, urine is then passed through here to the collecting duct where it is concentrated due to its permeability to water. It leaves the collecting duct into the pelvis of the kidney, which leads to the ureter and the bladder where it is store the urine
