UNIT : THE CHEMISTRY BEHIND THE 
RESPONSES 
STANDARD: 10 
OBJECTIVES : To understand about the 
functions adrenal gland 
TOPIC: ADRENAL GLAND
TOPIC : ADRENAL GLAND
ADRENAL GLAND & HORMONES
introduction 
 Endocrine glands 
 Suprarenal glands 
 Sit at the top of the kidneys 
 Right handed triangular shaped 
 Left handed semilunar shaped 
 responsible for releasing hormones
ADRENAL GLAND 
Two distinct parts 
 Outer adrenal cortex 
 Inner adrenal medulla
ADRENALGAdreno
Adrenal cortex 
 Corticoids 
 Divided into 3 layers 
1. Zona glomerulosa(outer layer) 
2. Zona fasciculata(middle layer) 
3. Zona reticularis(inner layer)
Adrenal cortex 
 Zona glomerulosa 
 mineralocorticoids 
 mainly aldosterone 
 functions of aldosterone: 
salt and water balance in body, 
Reabsorb sodium iones and water, 
Excretion of k+ and phosphate iones 
 Deficiency:Addison’s disease
Adrenal cortex 
 Zona fasciculata 
 Gluco corticoids 
 Cortisol, Cortisone, corticosterone 
 Functions : 
Increases blood glucose level, 
Promote gluconeogenesis, 
Stimulates RBC production, 
Breaks down Protiens & Fats, 
Stores glycogen in liver , 
Produces anti inflammatory reactions & 
suppresses the immune response 
 Cushing’s syndrome
Adrenal cortex 
 Zona reticularis 
 Gonado corticoids 
 Androgen & Oestrogen 
 Helps growth & functions of sex organs 
 Masculinisation - females 
 Gynaecomastia - males
ADRENAL MEDULLA 
 Adrenaline & Noradrenaline 
 Catecholamines 
 Emergency hormones or Hormones of fight / flight 
 Secreted in response to stimulation by sympathetic nerve 
 Functions : Increases heart beat ,Increase Pupilary dilation 
,Piloerection ,Sweating,Increase strength of heart 
contraction & rate of respiration , Breakdown of glycogen 
resulting in an increased concentration of glucose in blood, 
Breakdown of lipids & proteins,Increase Blood 
pressure,Increase blood supply to the extrimities
CONCLUSION 
 They modulate the functioning of every tissues , 
organ , glands 
 Have important effects on the way you think and feel 
 Enable your body to deal with stress from every 
possible source , ranging from injury and disease 
 To keep your body’s reactions to stress in balance so 
that they are appropriate and not harmful
QUESTIONS ?????............
Thank you
