MOST IMPORTANT SYSTEM OF HUMAN BODY

1. IMMUNE SYSTEM
• COMPONENT ORGAIN OF IMMUNE SYSTEM
• FUNCTIONS OF IMMUNE SYSTEM
• ENDOCRINOLOGY-ENDOCRINAL GLAND,
HORMONES, THEIR FUNCTIONS

2. IMMUNE SYSTEM
• The immune system is a complex network of
cells and proteins that defends the body
against infection. The immune system keeps a
record of every germ (microbe) it has ever
defeated so it can recognize and destroy the
microbe quickly if it enters the body again

3. COMPONENT ORGAIN OF IMMUNE
SYSTEM
• IMMUNE SYSTEM COMPONENTS.
• PRIMARY ORGANS: (lymphocyte production and
differentiation)
• BONE MARROW: B LYMPHOCYTE
• THYMUS: T LYMPHOCYTE
• SECONDARY ORGANS: (capture and processing of
antigens)
• SYSTEMIC:LYMPH NODES
• SPLEEN
• MUCOSAS:GROUPED:TONSILSPEYER'S PATCHES
• ISOLATED:FOLLICLES

8. FUNCTIONS OF IMMUNE SYSTEM
• The role of the immune system — a collection of
structures and processes within the body — is to
protect against disease or other potentially
damaging foreign bodies.
• The major function of the immune system is to
protect the host from environmental agents such
as microbes or chemicals, thereby preserving the
integrity of the body. This is done by the
recognition of self and response to non-self.

11. ENDOCRINOLOGY

12. HYPOTHALAMUS
• The hypothalamus is a
small region of the brain.
It's located at the base of
the brain, near the
pituitary gland. While it's
very small,
the hypothalamus plays a
crucial role in many
important functions,
including: releasing
hormones. regulating
body temperature

13. PITUTORY GLAND

14. PINEAL GLAND

15. THYMUS GLAND

17. THYROID GLAND

18. PANCREASE GLAND

19. ADRENAL GLAND

20. OVARIES GLAND

21. TESTICLE GLAND
• The main hormone secreted by
the testes is testosterone, an
androgenic hormone. Testosterone is secreted
by cells that lie between the seminiferous
tubules, known as the Leydig cells.
