Course Of BiologyObjectives:

What Is The Biology?• Branches Of Biology• Cell• Branches Of Cells• Skeleton System• Life Process• Bones• Types Of Bones


Sub Division Of Biology:Micro Biology = The Study Of Micro Organisms.

Ecology = The Study Eqelation Ship B/ween Organism And Their Environment.

Cell Biology (Ey tology) = The Study Of Living Cell

Embryology = The Study Of Development Of Embryo

Genetics = The Study Of Traits And Character ties Parents To Pass Through Into Their Children.


What Is Cell ?The Building Block Of Life Or The Smallest And Functional Structure Of Unit.

- Plant And Animals Are Unicellular Organisms - Multi Cellular Organism Are Made Up Of Number Of Cells

Example : Human BeingAnimal Cell Plant Cell * Vacuole - Nuclevs - Nuclevs * Chloroplast- Cytoplasm - CytoPlasm * Cell Wall - Cell Membrane - Cell Membrane


a) Movement b) Growth - Muscle + Bone - Muscle - Bone

c) Reproduction d) Excretion - Female - Skin -> Sweet - Male - Kidney -> Urine - Liver -> Posions e) Respire f) Respon- Gas – Exchange - Sense Of Organs

- In = Oxygen - Out= Carbondioxide

g) Feed - In Mouth

Human And Other AnimalsHuman Have 206 Of bones SkeletonAppendicular AxialSkeleton Is a System Of Bones And Other Materials Supporting

Function Of the Skeletono It Gives Support = Frame Work. (eg) Skullo It Gives Protection For Softer Tissue (eg)=

Craniumo It Gives Anchor In Muscles (eg) = Triceps.


Joints The Places Where Two Bones Meet Is Called Joints Types Of Joint• Synovial – Freely Movable (e.g) Pettela• Fibrous – Immovable (e.g) Cranium • Cartegenous - Slightly Movable (e.g) Vertabrea.

Types Of Bones- Shorter- Longer- Irregular- Flat


From Cell To OrganismSpecialized Cell Are • Tissue - To Carry Chemical• Organ - To Carry Message • System - To Provide Protection• Organism - To Absorbing Water• Species


Organ System:A. Digestive System - Broken Down Of Food B. Breathing System - Gas Exchange C. Circulatory System - Transport SubstanceD. Excretory System - Get Rid Of Passions E. Nervous System - Carries Message Around

a The Body


Sex Cells And Life Cycle:In Animals The Male Sex Cells – Are Sperm Which Are Made In The Testes. The Female Gamates - Are Eggs And Medeil Ovaries. Sperm: Has• Neck • Tail • Head Contain Nucleus.


Adult:Male Female Sperm Egg

2) Human and Others Animal Skeleton Is a System Of Bones Supporting Materials Human – Has 206 Of Bones Skeleton Has Divided • Appendicular Skeleton• Axial Skeleton


Digestion Food :Digestion Food Is Taken Place Digestive System Digestive Chemical Mechanical•Stomach * Mouth•Intestine * Teeth * TongueIn the Stomach Food Is Mixed With Gastric Juice Which Contains Pepsinogen .Bile Is A Liquid Made The Liver And Stores Gall Bladder .


Saliva + Food = Bolus Enzyme + Food = Chyme Salivary GlandSub-Maxilary Patoriod Gland
