ORGAN SYSTEMS OF THE BODY

 Brief Description:

Skeletal system:

Which consists of BODY BONES & CARTILAGE JOINTS

Functions: 
Support, Protection, give form and shape to the body; Act as levers for movement.

Muscular system:

Which consists of BODY MUSCLES ATTACHED TO SKELETON

Functions:
Skilled and gross body movement.

Nervous system:

Which consists of BRAIN,SPINAL CORD,ALL PERIPHERAL NERVES & ORGANS OF SENSATION.

Functions:
Co-ordination & direction of activities of body organs.

Integumentary system:

Which consists of SKIN & APPENDAGES (HAIR,NAILS,GLANDS)

Functions:
Protection against invasion from outside, Dehydration, Injury, and temperature regulation.

Digestive system:

Which consists of MOUTH,ORAL CAVITY,PHARYNX,ESOPHAGUS, STOMACH,INTESTINES,LIVER, PANCREAS,RECTUM.

Functions:
Ingestion,Digestion absorption of nutrients and ejection of residues.

Respiratory system:

Which consists of NOSE,NASALCAVITIES,LARYNX,TRACHEA,LUNGS.

Functions:
Exchange of Gases(Oxygen & Carbon dioxide),Acid base regulation.

Circulatory system:

Which consists of HEART,ARTERIES,VEINS, CAPILLARIES,BLOOD & BLOOD VESSELS.

Functions:
Transport of all nutrients, Cell products & wastes from all parts of the body.

Immune system:

Which consists of WHITE BLOOD CELLS, ANTIBODIES,BONE MARROW,LYMPH NODES,SPLEEN,THYMUS.

Functions:
Defense against foreign particles, micro-organisms, baterial,viral & parasitic bodies.

Urinary system:

Which consists of KIDNEYS,URETERS, URINARY BLADDER & URETHRA.

Functions:
Regulation of blood composition; Formation & elimination of urine.

Reproductive system:

Which consists of 
 FEMALE: OVARIES,FALLOPIAN TUBES,UTERUS,VAGINA,EXTERNAL GENITALIA,MAMMARY GLANDS.
MALE: TESTES,EPIDIDYMIS,VAS DEFERENS, SEMINAL VESICLES, PROSTATE GLAND & EXTERNAL GENITALIA.

Functions:
Production of sex cells (OVA & SPERM); Hormone production.

Lymphatic system:

Which consists of LYMPH NODES,NODULES,VESSELS,THYMUS & SPLEEN.

Functions:
Return of fluid to circulation; clearing of dead cells from body; As a part of immune system it acts as defence mechanism.

BACTERIAL GROWTH CURVE

  BACTERIAL GROWTH CURVE MEANING OF GROWTH: GROWTH means as we all know INCREASE. SO, hear  we speak about GROWTH OF BACTERIA but in DIFFERENT STAGES. GROWTH is the orderly increase in the sum of all the components of an organism. The increase in size that results when a cell takes up water or deposits lipid(fats) or polysaccharide is not true growth. CELL MULTIPLICATION is a consequence of cell division of unicellular organisms, growth leads to an increase in the number of single bacteria making up  a population, referred to as a culture. Measurement of microbial concentrations:   These concentrations can be measured in terms of cell concentration(the number of viable cells per unit volume of culture) or of biomass concentration (dry weight of cells per unit volume of culture).   CELL CONCENTRATION: The viable cell count is considered the measure of cell concentration. The Turbidity of cell concentration, measured by photoelectric means , ...

VIROLOGY

  VIROLOGY What is meant by VIROLOGY?  It is part of microbiology or pathology which deals with viruses or viral agents, their taxonomical properties, disease producing properties, cultivation and genetics.. There are different types of viruses - mainly ENVELOPED & NON ENVELOPED Viruses are seen only under ELECTRONIC MICROSCOPE. Only one virus is big enough to see under LIGHT MICROSCOPE ie POX VIRUS. LARGEST VIRUS - POX VIRUS SMALLEST VIRUS - PARVO VIRUS NON ENVELOPED / NAKED VIRUS  are more RESISTANT. ENVLOPED VIRUS are more SENSITIVE. All DNA virus are DOUBLE STRANDED except  PARVO VIRUS. All RNA virus are SINGLE STRANDED except REO VIRUS. MEMONICS: How to remember DNA VIRUSES ? HHAPPPPy H-  HERPES VIRUS H - HEPATITIS VIRUS A - ADENO VIRUS P -  POX VIRUS P -  PARVO VIRUS P - POLYOMA VIRUS P - PAPILLOMA VIRUS 2. Naked viruses: Give  PAPP smears and  CPR to a naked virus DNA:  P - PARVO A - ADENO P - POLYOMA P - PAPILLOMA RNA: ...
