Describe the path that the blood takes as it travels through the kidney, and the changes that take place in its composition as it moves through each structure of the kidney

What will be an ideal response?


Blood enters the kidney through arteries, whose small branches lead to glomeruli. The pressure in the vessels causes much of the plasma to leave the glomerulus and enter the nephron. Blood proteins and cells remain in the circulatory vessels. The blood then leaves the glomerulus into a second set of capillaries that surround the remainder of the nephron. As blood travels through these vessels it regains glucose, salt, and water removed from the urine by the nephron. The blood then enters the veins leading from the nephron, having lost urea, some water, some salt, and having retained most other organic molecules and blood cells.
