Sudaryti tik is vienasluoksnio endoteio, todel ju sieneles yra plonos, laidzios…

17
Q

Mazasis kraujo apytakos ratas

A

Kraujo kelias is sirdies i plaucius ir atgal i sirdi vadinamas mzuoju kraujo apytakos ratu. Is desniojo sirdies skilvelio pro pusmenulinius voztuvus isstumtas veninis kraujas plauciu arterijomis teka i plaucius. Cia vykstya duju - deguonies ir anglies dioksido - apykaita. I plaucius nuneses anglies dioksida, kraujas prisijungia deguoni ir virsta arteriniu krauju. Plauciu venomis arterinis kraujas grizta i kairiji priesirdi.

18
Q

Didysis kraujo apytakos ratas

A

Kraujo kelias is sirdies oi kitus organizmo organus ir audinius ir atgal i sirdi vadinamas didziuoju kraujo apytakos ratu. Is kairiojo sirdies skilvelio pro pusmenulinius voztuvus isstumtas arterinis kraujas plusta i aorta ir kitas arterijas. Kraujas kapiliarais cirkuliuoja po visa organizma, aprupindamas lasteles deguonimi ir pasalindamas is ju anglies dioksida. Taip jis virsta veniniu krauju. Virsutine ir apatine tusciomis venomis kraujas grizta i desniji priesirdi: virsutine tusciaja vena - is galvos.smegenu, ranku, o apatine - is vidaus organu ir koju.
