The Excretory System Flow Chart day 7

nephron

The functional unit of the kidney that filters blood and makes urine.

Nephron Structure

Glomerulus:

Bowman's Capsule:

Proximal Convoluted Tubule (PCT): T

Loop of Henle:

Distal Convoluted Tubule (DCT):

Collecting Duct:

Glomerulus function

It works like a filter, letting small molecules, water, and waste pass into Bowman's capsule, while bigger things like proteins and blood cells stay in the blood.

Bowman's Capsule

A cup-shaped structure that filters blood and collects water, waste, and small molecules.

Proximal Convoluted Tubule (PCT)

Reabsorbs useful substances like glucose, amino acids, salts, and water back into the blood.

Loop of Henle

Reabsorbs water and salts to help control water balance in the body.

descending limb of the Loop of Henle

Reabsorbs water from the filtrate.

ascending limb of the Loop of Henle

Reabsorbs salts but not water.

What is the distal convoluted tubule (DCT)

Adjusts salt, water, and pH levels in the filtrate.

Collecting Duct

Collects urine and reabsorbs water before urine leaves the kidney.

capillaries in the nephron

Small blood vessels that help with reabsorption and secretion.

kidney location and how is it protected

near the spine in at the middle of the back

protected by lower ribs and covered by layers of fat.

excretory system

helps to remove waste products such as nitrogenous wastes, salts and minerals from the body.
