EXCRETORY SYSTEM

EXCRETORY SYSTEM IN HUMAN

EXCRETION ORGAN CONSIST OF:
1. KIDNEY / REN = URINE
2. SKIN / INTEGUMAN = SWEAT
3. LIVER = GALL / BILE
4. PULMO / LUNG = WATER VAPOR + CO2

Kidney have 3 layer. There are :
1. cortex
2. medula
3. pelvis renalis

The function of kidney is filtering of blood.
Blood vessel that go into the renal is renal artery (arteri renalis)
Blood vessel coming out of the renal is renal vein (vena renalis)

The kidney compose many nefron.
The part of nefron devided 2, there are:
1. malphigi body
2. tubula

Malphigi body consist of:
1. glomerolus
2. capsula bowman

Tubula consist of:
1. tubulus contortus procsimal
2. tubulus contortus distal

The process of urine produce as follows
1. Filtration = it occur in the glomerolus
                       it produce primary urine
                       the substance filtration is globulin and protein
2. Reabsorbtion = it occur in tubulus contortus proksimal
                              it produce secondary urine
                              the substance reabsorbtion is glucose
3. Augmentation = it occur in the tubulus contortus distal
                               it produce urine
                               the waste substance from metabolisme, adding water etc.
after tubulus contortus distal urine distributed to tubulus kontortus colectifus.
Urine saved temporarily in pelvis renalis.
after pelvis renalis

The composed of skin layer consist of:
                  1. epidermis
                  2. dermis
                  3. hipodermis
Epidermis consist of 2 layer, there are:
                  1.
                  2.
Color of skin 
The function of skin (integumen) consist of :
                 -
                 -
The function of liver consist of:
                 - degradation the eritosit become iron substance, globin and heme.
                   Than heme produce gill/bile
                 - degradation of insulin
                 - degradation amonia become urea
 The function of pulmo (lung) consist of:
                - excretion of water vapor and
                - carbon dioxide
