Urine Formation/Urin Production

What are the 4 processes of urine formation ?i i

1. Glomerular Filtration

2. Tubular Reabsorption

3. Tubular Secretion

4. Water Reabsorption

Where does urine formation happen ?i i

Urine formation happens in the nephrons .i i

What does glomerular filtration move and where ?i i

Glomerular filtration moves water and solutes, except proteins, from the plasma into the nephron .i i

What 2 factors affect glomerular filtration ?i i

1. The opening in the capillaries are small to block blood proteins and cells .i i

2. The blood pressure is 4x greater in this region.

What is the fluid called when it leaves the glomerulus and enters the Bowman’s Capsule ?i i

The fluid is called filtrate .i i

Describe the process of tubular reabsorption .i i

This process removes useful molecules from the filtrate and returns it to the blood (capillaries) for further use in the body .i i

Describe the process of tubular secretion .i i

This process moves more wastes and excess substances from the blood into the filtrate .i i

Describe the process of water reabsorption .i i

This process removes water from the filtrate and returns it to the blood for reuse in the body .i i
