Resulting in the loss of a specific senses or action
54

55
What is the synapse
A gap between nurons
56
How do electrical impulses cross the synaps
Electrical impulse will be turned into a chemical call neurotransmitter wich diffuses across the gap
57
9 hormonal glands and where it is
Pineal - brain
Pituitary - brain

Pancreas - behind the stomach
Adrenal cortex - top of each kidney
Ovary
Testis
Hypothalamus - brain
Thymus - upper part of chest
58
Adrenal gland - hormone produced and what it does
Adrenalin
Prepares body for action [ increase heart rate]
59
Pancreas - hormone produces and what it does
Insulin
Lowers blood sugar levels to promote uptake of glucose
Glucagon
Raises blood sugar level, by converting carbohydrate store in muscles and the liver into glucose
60
Thyroid - hormone produced and what it does

Removal of urea
Regulations of water
63
What is rapid exit of plasma called
Ultrafiltration
64
Kidney - what is absorbed in reabsorption
Water 95%
Glucose
Amino acids
Vitamins
Most mineral salts
65
Regulation of water in the kidney
Loss of water increases the concentration of the blood and if left uncorrected it could result in our cells losing water by osmosis, as water now diffuses into the concentrated plasma.
The hypothalamus detects this rise in blood concentration and sends impluse to pituitary gland, releasing ADH, hormone travels all over the body till cells in the kidneys collecting ducts walls
66
Liver - what is deamination
Remove surplus amino acids, resulting in the production of urea
67
Liver - detoxification
Remove poisons (alcohol) by breaking them down into harmless components
68
What breaks down and recycle red blood cells
Liver cells ( as RB has no nucleus and only live for 3 months
69
Whats produced by recycling red blood cells and what do they do
Biliverdin
Bilirubin
Give the characterisic colour of faeces
70
What happends if biliverdin and bilirubin cant pass in the bile and if not treated
The chemical pass into the blood and results in a yellow tinge ( jaundice ).
