Excretion
Removal of metabolic waste from the body
1 of 13
Metabolic waste
Substances produced in excess from the metabolic processes in cells, it may be toxic
2 of 13
Hepatic portal vein
Connects the intestine to the liver
3 of 13
Ornithine Cycle
Series of biochemical reactions that convert ammonia into
4 of 13
Nephron
a functional unit of the kidney
5 of 13
Ultrafiltration
filtration of the blood at molecular level under pressure
6 of 13
Hypothalamus
part of the brain that coordinates homeostatic responses
7 of 13
Endotherms
an organism that uses heat from metabolic reactions to maintain body temperature
8 of 13
Ectotherms
rely on external sources for heat and body temperature fluctuates with external temperature.
9 of 13
Urea
synthesised from excess amino acids which the body cannot store
10 of 13
Deamination
Breaking down amino acids into ammonia .(Removing amine group from amino acid). amino acid+oxygen -> keto acid and ammonia
11 of 13
Detoxification of alcohols
Conversion of toxic molecules into less/non txic molecules
12 of 13
Basement membrane
contains a network of collagen fibres and glyoproteins. This prevents anything greater than 6900 RMM from being filtered in.
