a)
It is producing more hormones than usual.
b)
It is causing the kidneys to filter more blood.
c)
It is not correctly signalling the kidneys to remove excess water.
d)
It is sending signals to increase water reabsorption.
4.
A person drinks a large amount of water. Based on the reading, what action would the hypothalamus prompt the kidneys to take?
a)
Decrease the amount of urine produced.
b)
Increase the amount of urine produced.
c)
Increase the amount of water returned to the blood.
d)
Stop filtering blood entirely.
5.
How does kidney failure fundamentally disrupt the body's processes, considering the function of nephrons?
a)
It causes the bladder to expand too much.
b)
It makes the ureters unable to transport urine.
c)
It prevents blood from being properly filtered.
d)
It stops the liver from producing urea.
6.
Imagine the urinary system is a plumbing network. What would be the silliest thing to use instead of a proper ureter tube?
a)
A flexible, clear plastic straw.
b)
A smooth, straight drainage pipe.
c)
A fluffy, soft piece of string.
d)
A tiny, winding garden hose.
7.
A student states, 'The liver is not part of the excretory system because it doesn't directly remove waste from the body.' Is this statement accurate?
a)
Yes, waste removal is solely the kidney's job.
b)
No, the liver mainly stores urine.
c)
No, the liver produces urea, which is a waste product.
d)
Yes, the liver only processes nutrients, not waste.
8.
If a blockage occurs in the tubes carrying urine from the kidneys to the bladder, which organ is directly affected by this blockage?
a)
The urethra.
b)
The ureters.
c)
The liver.
d)
The hypothalamus.
9.

a)
Mild irritations.
b)
Blockages of tubes.
c)
Harmful germ attacks.
d)
Tiny growths.
10.
If a doctor asks for a urine test, what is a likely reason for this in a real-world setting?
a)
To measure how fast someone can run.
b)
To see if the person has an allergic reaction.
c)
To check how much water a person drinks.
d)
To find out about possible health problems.
11.
The reading describes cellular respiration as cells using oxygen to release energy. How does this compare to the overall process of 'breathing'?
a)
Breathing removes oxygen, while cellular respiration provides it.
b)
Both breathing and cellular respiration happen only in the lungs.
c)
Breathing moves air in and out, while cellular respiration uses oxygen within cells.
d)
Breathing is a chemical reaction, while cellular respiration is mechanical.
12.
What is the role of the epiglottis, a tissue flap in the pharynx?
a)
To allow gas exchange with the capillaries.
b)
To filter out pathogens from inhaled air.
c)
To produce vocal sounds.
d)
To prevent food or liquid from entering the airway.
13.
Which organ of the respiratory system contains the vocal cords used for speaking?
a)
Trachea
b)
Bronchi
c)
Larynx
d)
Pharynx
14.
In which part of the respiratory system does oxygen enter the blood and waste products exit the blood?
a)
Alveoli
b)
Bronchioles
c)
Pharynx
d)
Trachea
15.

It remains the same.
b)
It increases.
c)
It stops completely.
d)

c)
To contract and relax to move gas.
d)
To filter out dust from inhaled air.
18.
What is a major effect of chronic bronchitis on the respiratory system?
a)
The epiglottis fails to prevent food from entering the airway.
b)
Too much mucus is produced, and cilia can be damaged.
c)
The vocal cords become permanently damaged.
d)
The alveoli lose their ability to exchange gases.
