Excretion System

Question 1

Large Intestine

Answer 1

Removes toxic waste

Question 2

Liver

Answer 2

1) converts toxins into soluble compounds
2) Destroys old RBC by converting hemoglobin into bile
3) removes nitrogen wastes produces urea

Question 3

Lungs

Answer 3

Removes CO2

Question 4

Kidney

Answer 4

1) removes waste such as urea
2) balances blood PH
3) maintains water balance in blood
Cortex - filtration
Medulla- reabsorbtion
Renal pelvis - secretion

Question 5

Skin

Answer 5

maintains heat by producing sweat

sweat helps to excrete water

Question 6

Ureter

Answer 6

Brings waste to bladder

Question 7

Urinary Bladder

Answer 7

Temporary urine storage

Question 8

Urethra

Answer 8

Brings waste from bladder out of system

Question 9

Renal Artery

Answer 9

Brings oxygenated blood to kidneys

Question 10

Efferent Arteriole

Answer 10

Leaves glomerulus takes the blood to the capillary net

Question 11

Afferent Arteriole

Answer 11

Brings blood to glomerulus from the renal Artery

Question 12

Renal vein

Answer 12

Brings deoxygenated blood back into the heart

Question 13

Glomerulus

Answer 13

Ball of capillaries- site of pressure filtration

Question 14

Bowman s’ Capsule

Answer 14

Surrounds the Glomerulus, fluid from the blood that are to be urine enter the nephron here ( filtration )

Question 15

Proximal Tubule

Answer 15

( near to Bowman’s capsule)

important for reabsorbtion

Question 16

Distal Tubule

Answer 16

( distanced from the Bowman’s capsule)
leads to collecting duct
Site of secretion

Question 17

Collecting Duct

Answer 17

Collects urine from many nephron And empties waste to renal pelvis

Question 18

Renal Pelvis

Answer 18

Collecting site for all nephron, empties waste out to ureter (secretion)

Question 19

Nephron

Answer 19

Filters blood makes urine

Question 20

Deamination

Answer 20

amino acids ( nitrogen and hydrogen ) is removed.
occurs in the liver
used to produce ammonia

Question 21

urea

Answer 21

a compound of nitrogen that is dissolved in the urine

Question 22

ADH

Answer 22

Stored in the pituitary gland which releases it into blood

hormone that absorbs water

Question 23

Aldosterone

Answer 23

Produced in adrenal gland

Conserves sodium

Question 24

Kidney Dialysis

Answer 24

Cleaning of blood

Question 25

Hemodialysis

Answer 25

1-Blood is pumped to a machine/filter (artificial kidney)
2-Wastes diffuse from the blood into a solution low in solute
3-Cleaned blood is pumped back into the arm

Question 26

Diabetes Insipidus

Answer 26

Water is not being absorbed by ADH hormone

Huge urine output
