EXCRETORY SYSTEM IN HUMAN
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
