Describe The Structure Of The Nephron

Question 1

What does the collecting duct do? What structures support the collecting ducts?

Answer 1

Transport urine through the pyramids to the calyces.
The collecting ducts are supported by connective tissue, containing blood. Easels, nerves and lymph nodes

Question 2

Describe a nephron with its parts

Answer 2

Each nephron is essentially a tubule that is closed at one end and open into a collecting duct at the other.

The closed or blind end forms the cup-shaped glomerular (Bowman’s) capsule.
Which almost completely encloses a coiled tuft of capillaries, the glomerulus.

Question 3

What 3 parts of the nephron that come after the glomerulus?

Answer 3

1. The proximal convoluted tubule
2. The medullary loop (loop of Henle)
3. The distal convoluted tubule, leading into a collecting duct.

Question 4

Describe the function overview of the kidney

Answer 4

Renal blood and lymph nodes, the ureter and nerves enter and leave the kidney via the hilum (concave part in the middle)

Urine formed in the kidney passes through one of several openings in a renal papilla into the drainage system that begins at a minor calyx.

Several minor calyces merge into a major calyx, and two or three major calyces combine to form the renal pelvis

Walls of calyces and renal pelvis are lined with transitional epithelium and contain smooth muscle.

Peristalsis, intrinsic contraction of smooth muscle, propels urine through calyces, renal pelvis and ureter to the bladder.

The blood supply to the kidney is via the renal artery, a large branch of the abdominal aorta.
