Secretion and reabsorption throughout the nephron

Question 1

What is filtration?

Answer 1

Glomerular filtration rate (GFR) represents the flow of plasma from the glomerulus into Bowman’s space over a specified period and is the chief measure of kidney function.

Question 2

What is reabsorption

Answer 2

the proximal/distal convoluted tubules, loop of Henle, the collecting duct) as water and ions are removed as the fluid osmolarity (ion concentration) changes.

Question 3

What is secretion?

Answer 3

some substances such as hydrogen ions, creatinine, and drugs will be removed from the blood through the peritubular capillary network into the collecting duct.

Question 4

What is excretion

Answer 4

nitrogen (found in ammonia) to be removed from the body.

Urine also contains many salts and other waste components.

Question 5

What may indicate glomerulus injury and diabetes

Answer 5

Red blood cells and sugar found in urine
