what does the zona glomerulosa secrete
mineralocorticoids - aldosterone controlling levels of sodium and potassium in the blood -
3 of 18
what does the zona fasciculata
secretes glucocorticoids - control metabolism of different respiratory substances in the body - increases glucoses concentration - converts fats in glucose
4 of 18
zona reticularis
releases cortisol - precursors for sex hormones - bring about secondary sexual characteristics

adrenal medulla
secretion of adrenaline - response to stress

what detects threat
cerebrum then passes to the hypothalamus - activates sympathetic nervous system and then stimulates anterior pituitary gland

increases heart rate and pupil dilation - releases noradrenaline which binds to adrenaline and causes adrenal medulla to release adrenaline
peptide hormone - amino acid or steroid - lipids hormone

type 1
body cannot produce enough insulin - autoimmune attack - glucose rises to a high level

type 2
the body produces insulin but the cells do not respond properly to it - insulin receptors are less sensitive - permanently raised level of blood glucose

risk factors of type 2
obesity, high sugar diet and lack of exercise, being from Asia or having a family history of type 2 diabetes

treating type 1
insulin injection, attached pumps, replace dead beta cells in the pancreas - transplanting beta cells or whole pancreas transplant or use stem cells
