•As we discuss the pathways that air and
food must travel, count how many systems are
involved.

What system do you think of when you think of getting air?
What is the pathway for a cell to get oxygen (air)?

Why do doctors want a urine sample from you?
![Page 24: Needs of the Organism are met at the Cell level Identify the steps of how cells of the body use organs and tissues to get food and air and get rid of wastes?](https://reader035.vdocuments.site/reader035/viewer/2022070305/5515ba4555034674578b62ce/html5/thumbnails/24.jpg)
• It is possible to discover diseases of many different organs of the body with a urine test.
• The sample can be taken alone if, for instance, the purpose is to find out if you suffer from cystitis. In other cases it will be taken along with other tests (such as stool or blood tests) as part of the investigation process.
• A urine test is a cheap, simple test that can provide a lot of important information, for example:
-blood in the urine may be a sign of different diseases in the kidneys, the urinary system or the bladder.
-sugar in the urine may be a sign of diabetes.-protein in the urine may be a sign of a kidney disease and can be used to detect the early signs of kidney
damage from long-standing diabetes.

• Take turns and see if you can tell your partner the pathways for a cell to get:
• Oxygen• Food/Water
• Get rid of Waste
