Endocrine System

Anatomy of Endocrine System:

Endocrine System Functions:

1. Regulate body activity

2. Regulate body metabolism

3. Regulate sleep, hungry, etc

4. Regulate blood pressure

5. Regulate body fluid

6. Regulate blood glucose level

Endocrine Glands Functions:
1. Hypothalamus:
Regulate endocrine system activity (releasing hormones, oxytocin & ADH)--> Stimulate   the glands

2. Pituitary glands:
Pituitary gland anterior: Produce hormones (TSH, GH, etc)Pituitary gland posterior: Store hormones (oxytocin & ADH)

3. Pineal glands: Produce melatonin--> Biology clock

4. Thyroid gland:
Produce FSH--> Regulate body metabolism
Produce calcitonin--> Decrease calcium level in the blood

5. Parathyroid gland: Produce Parathyroid hormone--> Decrease calcium level in the blood

6. Adrenal gland:
a) Cortex adrenal:
Steroid hormone:
Aldosteron--> Regulate body fluid & blood pressure
Cortisol--> Increase blood glucose level, protein & fat breakdown

Sex hormone: 
Testosterone--> Stimulate sperm production & secondary sex characteristic
Estrogen & Progesteron-->
- Stimulate ovum production & secondary sex characteristic
- Stimulate the development of uterus wall

b) Medulla adrenal: Produce adrenalin--> Increase heart rate

7. Pancreas:
Produce insulin & glucagon--> Regulate blood glucose level

8. Ovaries:
Produce progesterone & estrogen-->
- Stimulate ovum production &secondary sex characteristic (feminine effect)
- Regulate menstrual cycle & pregnancy

9. Testicles:
Produce testosterone-->
- Stimulate secondary sex characteristic (masculine effect)
- Sperms production
