Excretion Test

Question 1

How is Carbon Dioxide produced? (Metabolic waste)

Answer 1

Co2 is produced in the body during cellular respiration which is the break down of glucose in cells to create ATP.

Question 2

How is Water produced? (Metabolic waste)

Answer 2

Water vapor is produced by cellular respiration (breakdown of glucose in cells to create ATP) and is discarded when we exhale.

Question 3

How is Ammonia produced? (Metabolic waste)

Answer 3

Amino acids are produced and broken down in the liver, here is where ammonia is found.

Question 4

How is Urea produced? (Metabolic waste)

Answer 4

Ammonia is shifted to be urea in the liver which is less harmful and can transport excessive nitrogen.

Question 5

How are Mineral Salts produced? (Metabolic waste)

Answer 5

Body produces mineral salts from breaking down food and absorbing water in the digestive system.

Question 6

Skin, Lungs, Kidneys, and the Large Intestine are the major what?

Answer 6

The four major excretory organs

Question 7

What do the Lungs excrete?

Answer 7

Carbon Dioxide and Water Vapor

Question 8

What does the skin excrete?

Answer 8

Excess water, excess salts, and urea

Question 9

What do the Kidneys excrete?

Answer 9

Water and some salts

Question 10

Why is the liver not considered an excretory system?

Answer 10

Its a site of metabolic waste production which is not considered excretion.

Question 11

What is the function of the Kidney?

Answer 11

The kidney filters blood to remove waste, and extra water, and produce urine.

Question 12

What is the function of the Renal Artery?

Answer 12

A large blood vessel branches into smaller vessels until the blood reaches the nephrons. Blood flows into the kidney through this artery.

Question 13

What is the function of the Renal Vein?

Answer 13

Cleansed blood goes into this vein carrying blood from the kidneys and back to the heart. From the heart, the cleansed blood will recirculate through the body.

Question 14

What is the function of the Renal Medulla?

Answer 14

The inner part of the kidney has a “stripped” appearance because it contains microscopic coiled tubules called nephrons.

Question 15

What is the function of the Renal Pelvis?

Answer 15

The Renal Pelvis collects the urine that was produced in the kidneys and leads it out through a central “stem” called the ureter.

Question 16

What is the function of the ureter?

Answer 16

Where urine flows down the ureter and empties into the urinary bladder; urine is stored.

Question 17

What is the function of the Urinary Bladder?

Answer 17

Where urine is stored, it can hold 600mL of fluid from 2-5 HRS. Nerves in the bladder send a message to the brain when the bladder is full.

Question 18

What is the function of the Urethra?

Answer 18

Urine is released from the bladder, flowing through the urethra and out of the body.

Question 19

What is the function of the Urinary Sphincter?

Answer 19

Controls the drainage of urine from the bladder to the urethra. Its made of two rings (internal and external) that control the bladder from the urethra.

Question 20

What are the three processes that nephrons undergo to rid the blood of waste?

Answer 20

1. Filtration
2. Reabsorption
3. Secretion

Question 21

What are the 6 things detected when using a urinalysis test?

Answer 21

1. Kidney Disease
2. Diabetes
3. Liver Disease
4. UTI’s
5. Recreational Drugs
6. Pregnancy

Question 22

Describe the Visual Examination method when looking at urine.

Answer 22

Visual examination when looking at urine is when someone is looking at the color and clarity of urine.

Question 23

Describe the Dipstick method

Answer 23

Using a chemically treated stick to determine the PH level of the urine.

Question 24

Describe the Microscopic method

Answer 24

Small samples of urine are examined under a microscope.
