Drugs & Excretion in humans Flashcards
Carbon dioxide is excreted through
The lungs
The kidneys excrete
urea and excess
water and ions
The function of the glomerulus is
ultrafiltration from the blood of water, glucose, urea and
ions.
The function of the nephron
reabsorption of all the glucose, some of the ions and
most of the water back into the blood.
Urine contains
urea, excess water and excess ions.
Role of liver
the assimilation of amino acids by converting them to proteins.
Urea is formed in the
liver from excess amino acids.
Deamination
emoval of the nitrogen-containing part of amino acids to form urea
Urea is toxic
it can lower the pH of the body and denature the enzyme. Denaturing
of enzyme might lead to death of the individual therefore excretion of urea is
important.
Drug
any substance taken into the body that modifies or affects chemical reactions
in the body
Antibiotics are used to
treat bacterial infections.
Some bacteria are resistant to antibiotics which
the effectiveness of
antibiotics.
Antibiotics kill bacteria but do not affect
