Usulhoi tanzimi funksiyahoi organizm

Dar organizmi odam hujayraho, boftaho, azo va sistemai onho hamchun yak chizi yagona va butun kor mekunand. Kori onho bo du roh: humorali (moddahoi khimiyavi tavassuti moei muhiti dokhilii organizm –khun, limfa, moei baynihujayra surat megirad) va asabi tanzim karda meshavad.

Moddahoi kimiyovi ba hujayraho, boftaho, uzvho va umuman digar ravandhoi organizm tasir rasonida, kori onhoro tanzim menamoyand. Miqdori kami moddaho qobiliyati balandi tasirkuni dorand. Binobar in onhoro moddahoi faoli biologi menomand, ki hujayrahoi makhsusi organizm az khud judo mekunand. Ba in uzvho, pesh az hama, gadudhoi tarashshuhi (sekretsiya) dokhili taalluq dorand.

Az jihati tarashshuh onho ba du guruh judo meshavand. Gadudhoi tarashshuhi beruni mahsuli khudro ba kovokihoi badan khorij mekunand. Gadudhoi tarashshuhi dokhili mahsuli khudro faqat ba khun medihand. Ba gadudhoi tarashshuhi beruni gadudhoi luobi dahon, ashkbaror, araqjudokunanda, jigar va gadudhoi medayu rudaho dokhil meshavand.

Tanzimi asabii vazifaho. 

Magzi sar va harommagz tavassuti torhoi asab tamomi uzvhoi organizmro bo ham aloqamand mekunand. Sistemai asab ham ba monandi hormonho ba uzvho tasir rasonida, korashonro tez yo sust mekunad. Binobar mavjudiyati magzi sar organizm az tagyiryobii sharoiti muhit muntazam bokhabar meshavad, chunki bayni magzi sar va tamomi uzvho aloqamandii tarafayn mavjud ast.

Tanzimkunandahoi asabi va humorali aloqamandii dutarafa va kori bo ham muvofiqi sistemai uzvhoro amali megardonand. Az hamin sabab organizm hamchun yak chizi butun (tom) amal mekunad. In du sistema poydorii muhiti dokhili va ustuvorii tamomi vazifahoi organizmro dar natijai khudtanzimkuni tamin mekunand. Hudtanzimkuni gufta, holatero menomand, ki har yak digarshavii tarkibi muqarrarii muhiti dokhilii organizmro sistemai asabi va humorali ba holati avvalaash barmegardonad.  Misol, dar vaqti ziyod shudani miqdori qand (glyukoza) dar khun sistemai asabi va humorali ba kor daromada, miqdori qandro kam mekunand. 

Savolho

  1. Faoliyati ba ham muvofiqi hujayraho, boftaho, uzvho va sistemai onho bo chi tamin megardad?
  2. Tanzimi humorali chist?
  3. Farqi bayni gadudhoi tarashshuhi beruni va dokhili dar chist?
  4. Tanzimi asabi chist?
  5. Hudtanzimkuni chist?
