Atherosclerosis (qee zaus hu ua "hardening" lossis "clogging" ntawm cov cov hlab ntsha ) yog txhim kho txo cov roj (cholesterol) thiab fatty deposits (hu ua plaques) nyob rau sab hauv phab ntsa ntawm lub cov hlab ntsha . Cov plaques no tuaj yeem txwv ntshav ntws mus rau lub plawv nqaij los ntawm lub cev clogging cov leeg los yog los ntawm ua rau txawv txav cov leeg laus thiab muaj nuj nqi.
Tsis tas li ntawd, yog qhov tshwm sim ntawm cov ntshav ntws mus rau lub plawv?
Cov txo cov ntshav khiav feem ntau yog tshwm sim ntawm ib feem los yog tag nrho blockage ntawm koj lub plawv cov hlab ntsha (cov hlab plawv). Myocardial ischemia, kuj hu ua mob plawv ischemia, cov tsos mob txo cov plawv cov leeg muaj peev xwm mus twj ntshav . Sudden, hnyav blockage ntawm ib qho ntawm lub plawv cov hlab ntsha tuaj yeem ua rau a plawv nres.
Qhov thib ob, cov cim ceeb toom ntawm cov hlab ntsha txhaws yog dab tsi?
- Mob hauv siab.
- Ua tsis taus pa.
- Lub plawv palpitations.
- Tsis muaj zog lossis kiv taub hau.
- Ntshai.
- Tawm hws.
Hauv qhov no, puas tuaj yeem thim rov qab cov roj ntsha hauv cov hlab ntsha?
Plaques pib hauv cov leeg phab ntsa thiab loj hlob ntau xyoo. Thaiv cov hlab ntsha tshwm sim los ntawm cov quav hniav txhim kho thiab cov ntshav txhaws yog qhov ua rau tuag hauv Asmeskas txo cov roj cholesterol thiab lwm yam kev pheej hmoo tau pab tiv thaiv cov cholesterol plaques los ntawm kev tsim. Qee zaum, nws tau txawm thim rov qab ib co plaque buildup.
Cov quav hniav ntawm cov ntshav ntws zoo li cas?
Atherosclerosis yog ib yam kab mob uas cov plaque tsim hauv koj cov hlab ntsha. Cov hlab ntsha yog cov hlab ntsha uas nqa cov ntshav uas muaj oxygen rau koj lub plawv thiab lwm qhov ntawm koj lub cev. Plaque yog tsim los ntawm cov rog, roj cholesterol, calcium, thiab lwm yam khoom muaj nyob hauv cov ntshav. Thaum lub sij hawm, cov quav hniav hardens thiab ua rau koj cov hlab ntsha.

Puas yog qhov txo qis ntshav ntws mus rau lub plawv tshwm sim los ntawm kev tsim cov rog rog hauv cov hlab ntshav?
Atherosclerosis (qee zaum hu ua 'hardening' lossis 'clogging' ntawm cov hlab ntsha) yog kev tsim cov roj (cholesterol) thiab cov rog tso (hu ua plaques) ntawm cov phab ntsa sab hauv ntawm cov hlab ntsha. Cov quav hniav no tuaj yeem txwv cov ntshav ntws mus rau cov leeg nqaij hauv lub cev los ntawm kev txhaws cov hlab ntshav lossis ua rau lub suab nrov txawv txav thiab ua haujlwm
Dab tsi tsuas yog lim los ntawm cov hlab ntshav los ntawm glomerulus thiab tsis rov qab nqus mus rau hauv cov hlab ntshav tab sis tawm los ntawm cov zis?
Creatinine yog cov khoom pov tseg los ntawm cov leeg tawg thiab raug tshem tawm los ntawm cov ntshav los ntawm glomerulus ntawm nephron. Nws tsuas yog cov khoom uas tsuas yog lim tawm ntawm cov ntshav tab sis TSIS tau rov ua dua rau hauv lub cev. Nws raug tso tawm los ntawm cov zis
Cov hlab ntsha qis hauv cov hlab ntsha ntws mus rau qhov twg?
Brachiocephalic leeg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
