Cov lymphatic hlab ntsha ntws mus rau hauv khaws cov ducts, uas khoob lawv cov ntsiab lus rau hauv ob lub subclavian leeg, nyob rau hauv lub collarbones. Cov leeg no koom nrog rau tsim qhov zoo tshaj plaws vena cava, cov hlab ntsha loj uas tso ntshav los ntawm lub cev sab saud mus rau hauv plawv.
Ua li no, qhov lymphatic system khoob rau hauv cov hlab plawv cov lus nug li cas?
Txoj cai sab sauv sab xis, txoj cai sab sauv, thiab empties rau hauv txoj cai subclavian leeg uas nws nkag mus rau hauv circulatory system.
Qhov thib ob, puas yog cov qog ntshav ua ib feem ntawm cov hlab plawv? Cov lymphatic system yog ib feem ntawm cov hlab ntsha , muaj xws li ib tug network ntawm inter-txuas raj hu ua cov hlab ntsha lymphatic uas nqa cov kua ntshiab hu ua lymph mus rau plawv . Cov lymphatic system thauj cov qe ntshav dawb uas yog qhov tseem ceeb hauv kev tiv thaiv kab mob tiv thaiv kab mob.
Cov lus nug tseem yog, cov lymphatic system ua haujlwm li cas nrog cov hlab plawv?
Cov lymphatic system ua haujlwm nrog cov hlab plawv kom rov qab cov kua hauv lub cev mus rau cov ntshav. Cov lymph, cov kua ntshiab pom nyob rau hauv lub lymphatic system , tau txav mus los hauv cov hlab ntshav los ntawm qhov kev txiav txim ntawm cov leeg du thiab cov leeg pob txha.
Cov qog ntshav rov qab los rau lub siab li cas?
Cov kua dej no hu ua lymph . Tsis muaj plawv -Zoo li lub twj tso kua mis rau lymphatic qhov system. Hloov chaw, thaum koj ua pa thiab txav koj cov leeg, lub lymph txuas ntxiv tau thawb mus rau plawv los ntawm sab nraud ntawm koj lub cev. (Nws zoo ib yam li cov ntshav depleted ntawm oxygen txav rov qab mus rau koj plawv los ntawm cov leeg.)

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
Hom hlab ntshav twg txuas cov hlab ntsha thiab cov hlab ntshav?
Hom hlab ntsha Capillaries yog feeb nyias-walled hlab ntsha uas txuas cov hlab ntsha thiab venules; Nws yog los ntawm cov capillaries uas cov as-ham thiab cov pov tseg tau pauv ntawm cov ntshav thiab cov ntaub so ntswg ntawm lub cev
Cov hlab ntsha twg tuaj yeem khaws cov qog ntshav los ntawm lub hauv siab thiab hauv qab hauv lub cev?
Cev thoracic
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
