Very hard because of collagen and calcium

salts.

Consist of bone cells : osteocyteOsteocyte form by osteoblast

Haversian canal system : lamela, lakuna,

kanalikuli, dan saluran havers.

Is a concentrically matriks layer

consist of minerals, and collagen fiber.

Minerals make the bones solid, tight. Collagen fiber make the bones

strong.

is a small space between lamela

Osteocycte inside

is a canal to nutrition needed bybones and to take out residuesubstance.

is a specialized connective tissue to carry

nutrition and metabolism residue.

Plasma and cellsConsist of eritrosit, leukosit, trombosit,

and blood plasma.

the average human has 5 litres of bloodit is a transporting fluidit carries vital substances to all parts

of the body

Biconcave shape, diameter 8m. No nucleus sitoplasm : hemoglobinRed blood cells carry oxygen to

body tissues and remove carbondioxide

They are red because they containa protein called hemoglobin that isred in color.

Have nucleusNo hemoglobin

the bodies defencepart of the immune systemAmoeboidmuch larger than RBCsBased granule divide to :

- Granulose- A granulose


12/34

Granulosit

Have granule in cytoplasmAround 60 % - 70 % from whole leukocyteConsist of : Neutrofil, Eosinofil, and

Basofil

Neutrofil Eosinofil Basofil

AgranulocyteDont have granule

Divide to : Limfocyte and monocyte

Limfocyte onocyte

If a blood vessel is cut, plateletsstick to the edges of the cut andto one another, forming a plug

that stops bleeding.They then release chemicals that

react with fibrinogen and otherclotting proteins, leading to the

formation of a blood clot.The blood vessel can then heal

over the cut area.

Responsibility of movement

Movement : contraction of

contractile fiber Actins andmyosin

plasma membrane : sarcolema

Sitoplasma : SarcoplasmaFiber : miofibril

- Muscles are the motors of

vertebrate bodies- Three kinds: smooth, skeletal and

cardiac

- Skeletal and cardiac muscles arealso known as striated muscles

- Skeletal muscle is under voluntary

control, whereas contraction of theother two is involuntary

are found in walls of bloodvessels and visceral organs :

blood vessels, eye, glands,uterus, Cells are mono-nucleated. involuntarily

- is composed of smaller,

interconnected cells

- Each with a single nucleus- Interconnections appear as dark

lines called intercalated disks

- Enable cardiac muscle cells to form

a single functioning unit

are tissues that have possibility to

accompany impuls (signal) to whole body.

nerve cell : neuronBased on function neuron divide to :

sensory : from receptors to effector

(Brain)

motory : from effector (brain) toreceptors

Sinapsis : space betweenneurons

Neurotransmitter : carry impuls

futhermoreNeutransmitter : asetilkolin
