The Excretory System
Draw the structure of the urinary excretory system in
humans
Label these parts -- kidney, ureter, urinary bladder, and
urethra
Give the basic function of the urinary excretory system in
humans
4
Explain the role of the kidney in regulating body fluids
5
Explain the role of the kidney extracting wastes and toxins
from the blood and recycling valuable substances
Explain the term filtration, reabsorption and secretion -thus regulating the body fluids and chemistry of the body
6
7
Explain the term filtration
8
Explain the term reabsorption
9
Explain the term secretion
10
Identification of the site of filtration and reabsorption in the
cortex, medulla and renal pelvis
11
Identify the position of secretion in the kidney
12
Describe the pathway of urine from the kidney to the
urethra
13
Recognise and label a T.S of human skin
14
Write a report on “Unhealthy Urinary Systems” include
 bacterial urinary tract infections
 formation of kidney stones
 renal tubule failure
 dialysis
 kidney transplants
15
Draw the Nephron and its associated blood supply
16
Explain how urine is formed
17
Why the blood is under pressure in the glomerulus
18
Why the plasma is force-filtered
19
Say what components of the plasma are not filtered and
why
20
Explain the term " Glomerular filtrate"
21
Explain the term "proximal convoluted tubule "
Red
Orange
Green
22
Explain what substances are reabsorbed into the blood
23
Explain how substances are reabsorbed into the blood
24
Give the roles of the Loop of Henle and the distal convoluted
tubule
25
Give some of the components found in urine
26
Give the pathway for urine from the nephron to the kidney
27
Explain how reabsorption of water in the collecting duct is
under hormonal influence
28
Explain the term osmoregulation
29
Show how osmoregulation is an example of a homoeostatic
mechanism
30
Give the pathway for urine from the nephron to the kidney
31
Explain how reabsorption of water in the collecting duct is
under hormonal influence
32
Give the full name for ADH
33
Say what conditions stimulate ADH release
34
Explain how ADH secretion [action] depends on the water
content of the blood.
