Kidney Functions

Front 1

One of the major functions of the kidney is to:

Back 1

Purify blood

Front 2

What part of the kidney must the blood first enter in order to get purified?

Back 2

The first step is filtering the blood in a structure called the glomerulus.

Front 3

What happens to cells and proteins that are too large to pass thru the glomerulus?

Back 3

cells and large proteins that do not pass through the glomerulus are retained in the blood stream

Front 4

What happens after products get purified in the kidney?

Back 4

They are lost via urination

Front 5

How does the kidney prevent water, digested food, hormones, salts,etc from leaving the body?

Back 5

water, digested food, hormones, salts, would leave the body if the kidney did not have a means of putting them back into the blood stream. This replacement is called reabsorption

Front 6

Which two mechanisms are needed in order to allow molecules to re-enter the blood stream?

Back 6

Diffusion and osmosis are the mechanisms by which necessary molecules re-enter the blood stream

Front 7

Where do molecules move to during diffusion?

Back 7

diffusion is the movement of molecules from an area of higher concentration to one of lower concentration.

Front 8

What is Dialysis Tubing used to measure?

Back 8

Dialysis tubing can be used to create an artificial cell to study the movement of molecules across a membrane.

Front 9

Define Osmosis:

Back 9

Osmosis is the passage of water across a semi-permeable membrane.
