Cov dej khov puas ua rau vasodilation lossis vasoconstriction?
Yuav tsum ua kom yooj yim, cov dej khov ua rau cov hlab ntsha hauv zos nqaim ( vasoconstriction), thaum tshav kub yuav ua rau cov hlab ntsha nce siab (vasodilation).
Cov tsos mob ntawm vasoconstriction yog dab tsi?
Ntshai thiab mob hnyav nrog vasoconstriction
- mob taub hau.
- kiv taub hau, poob nyiaj.
- loog lossis qaug zog ntawm ib sab ntawm lub ntsej muag thiab lub cev.
