The document discusses the adrenal gland and its hormones. The adrenal gland sits atop the kidneys and has two parts - the adrenal cortex and adrenal medulla. The adrenal cortex secretes corticosteroids like aldosterone and cortisol which regulate salt balance, blood sugar, and the immune system. The adrenal medulla secretes catecholamines like adrenaline and noradrenaline which trigger the body's fight or flight response and increase heart rate and blood pressure. In summary, the adrenal gland regulates important bodily functions through the hormones it secretes from its cortex and medulla.

3. ADRENAL GLAND & HORMONES

4. introduction
 It is an Endocrine gland
 It also know Suprarenal glands
 Sit at the top of the kidneys
 It has Right handed triangular shaped and
Left handed semilunar shaped
 It is responsible for releasing hormones

5. ADRENAL GLAND
It has two distinct
parts
 Outer adrenal cortex
 Inner adrenal medulla

7. Adrenal cortex
 Hormone secreted by adrenal cortex called Corticoids
 Adrenal cortex is divided into 3 layers
1. Zona glomerulosa(outer layer)
2. Zona fasciculata(middle layer)
3. Zona reticularis(inner layer)

8. Adrenal cortex
Hormone secreted by 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

9. Adrenal cortex
 Hormones secreted by 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
 Deficiency :Cushing’s syndrome

10. Adrenal cortex
Hormones secreted by Zona reticularis
 Gonado corticoids
 Androgen & Oestrogen
 Functions :Helps growth & functions of sex organs
 Masculinisation - females
 Gynaecomastia - males

11. ADRENAL MEDULLA
Hormones secreted by Adrenal medulla are 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

12. 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
