Tsamaiso ea endocrine e na le eng?
Litho tsa sehlooho tsa endocrine system ke:- tšoelesa ea qoqotho le thymus;
- gland ea gine le gland ea pituitary;
- litšoelesa tsa adrenal;
- manyeme
- testicles ho banna kapa mae a bomme ho basali.
Bakeng sa ho khetholla pakeng tsa lisele tsa sephiri tse kopaneng le tse hasaneng, sisteme eohle ea endocrine ea motho e arotsoe ka:
- glandular (e kenyelletsa le litšoelesa tsa endocrine)
- ferekanya (khetlong lena re bua ka lisele ka bomong).
Mesebetsi ea litho le lisele tsa tsamaiso ea endocrine ke eng?
Karabo ea potso ena e tafoleng e ka tlase:

| Hypothalamus | Taolo ea tlala, lenyora, boroko. Ho romella litaelo ho ea gland ea pituitary. |
| Tšoelesa ea tlhaho | E ntsha lihormone tsa kholo. Hammoho le hypothalamus e hokahanya tšebelisano ea endocrine le tsamaiso ea methapo. |
| Thyroid, parathyroid, thymus | Laola lits'ebetso tsa kholo le kholo ea motho, mosebetsi oa tsamaiso ea hae ea methapo, ea boits'ireletso le ea motor. |

Endocrine system le lefu la tsoekere
Makhopho a pancreas a etselitsoe ho hlahisa insulin ea hormone. Kantle ho eona, tsoekere e ke ke ea robeha 'meleng. Mofuta oa pele oa lefu lena, tlhahiso ea insulin e nyane haholo, 'me sena se senya mekhoa e tloaelehileng ea metabolic. Mofuta oa bobeli oa lefu la tsoekere o bolela hore litho tsa ka hare li hlile li hana ho amohela insulin.
- Ha ho karohano ea glucose e etsahetseng 'meleng.
- Ho batla matla, boko bo fana ka letšoao la ho felisoa ha mafura.
- Nakong ea ts'ebetso ena, ha ho thehiloe glycogen feela e hlokahalang, empa le likhomphutha tse khethehileng - li-ketones.
- 'Mele oa Ketone o chefo mali le kelello ea motho. Liphetho tse sa rateheng ke ho ba le lefu la tsoekere le lefu.
Ehlile, ena ke nyeoe e mpe ka ho fetisisa. Empa sena se ka etsahala ka lefu la tsoekere la mofuta oa II.
Endocrinology le karolo ea eona e ikhethang, lefu la tsoekere, li kenelletse ho ithuteleng lefu la tsoekere le ho batla kalafo e sebetsang.
Hona joale bongaka ha bo e-so tsebe ho etsa makhopho a sebetse, ka hona mofuta oa pele oa lefu la tsoekere o phekoloa feela ka kalafo ea insulin.
