Nco ntsoov tias cov kua hauv cov ntshav hu ua li cas: erythrocytes, ntshav ntshav lossis lymph? Muaj teeb meem teb? Cia wb nco ntsoov ua ke.
Dab tsi yog ntshav
Nws nyuaj rau ntseeg, tab sis ntshav yog hom kab mob sib txuas. Thiab nws yooj yim txaus los ua pov thawj nws. Cov ntshav muaj ib feem ua kua thiab cov qe ntshav. Thawj yog cov tshuaj intercellular. Muaj ntau ntawm nws, yog li tag nrho cov ntaub so ntswg ntawm ib puag ncig sab hauv yog xoob thiab tsim lub hauv paus ntawm lub cev. Thiab cov ntshav yog cov hlwb uas nyob hauv nws. Lawv tseem hu ua cov khoom zoo li tus.
Plasma thiab kua dej hauv lub cev
Cov kua dej ntawm cov ntshav hu ua plasma. Nws lub xeev ntawm kev sib sau ua ke thiab lub cev muaj zog feem ntau txiav txim siab ua haujlwm ntawm cov ntaub so ntswg. Nws yog cov kua daj daj, uas muaj viscosity tseem ceeb vim muaj cov proteins thiab tsim cov ntsiab lus hauv nws. Nws feem hauv cov ntshav yog kwv yees li 60%.
Ib puag ncig sab hauv ntawm lub cev yog cov ntshav, lymph, cov kua dej. Dej yog qhov tsim nyog yuav tsum tau ua ua ntej rau cov txheej txheem tshuaj lom neeg ntawm kev sib txuas thiab kev tawg ntawm cov khoom, nrog rau lawv txoj kev thauj mus los hauv lub cev.
Plasma chemistry
Cov kua dej ntawm cov ntshav hu ua plasma thiab yog nws cov tshuaj intercellular. Nws yog 90% dej. Proteins yog nyob rau hauv feem pua, tus nqi uas nce mus txog 8%. Cov no yog fibrinogen, albumins thiab globulins. Cov proteins no muab cov dej metabolism thiab kev tiv thaiv kab mob humoral, thauj cov tshuaj hormones, thiab tswj osmotic siab.
Ntau yam tsawg dua lwm cov organic hauv cov ntshav plasma. Carbohydrates ua 0.12%, thiab cov rog tsawg dua - 0.7%.
Cov khoom xyaw ntxhia ntawm cov ntshav ntshav yog sawv cev los ntawm cov ntsev. Cov tshuaj no muaj nyob rau hauv daim ntawv ntawm cov nqi them. Cov no yog sodium, magnesium, potassium, calcium, hlau, thiab tooj liab cations. Cov khoom tsis zoo muaj xws li cov seem ntawm chloride, carbonate, orthophosphoric thiab lwm yam ntxhia acids. Lub luag haujlwm tshwj xeeb ntawm cov tshuaj no yog rau saline. Nws cov ntsiab lus hauv plasma yog ib txwm nyob rau theem tsis tu ncua. Qhov no yog ib qho kev daws ntawm sodium chloride nyob rau hauv dej, ntsev concentration nyob rau hauv uas yog 0.9%. Nyob rau hauv cov ntaub ntawv ntawm cov ntshav poob, qhov no yog siv los kho nws qhov xav tau ntim. Qhov no tseem ceeb heev, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas nws tsis tuaj yeem tsim pab pawg thiab Rh yam ntawm tus neeg xav tau kev pab kho mob.
qe ntshav
40% ntawm cov ntshav yog nws cov khoom tsim, txhua hom uas yog tus cwj pwm los ntawm qee yam qauv thiab kev ua haujlwm. Yog li, erythrocytes yog cov pob liab liab ntawm cov duab biconcave. Cov hlwb no tsis yog nuclear thiab muajhemoglobin. Lub luag haujlwm tseem ceeb ntawm erythrocytes yog pauv roj. Lawv thauj cov pa oxygen los ntawm lub ntsws mus rau txhua lub cell hauv lub cev, nrog rau cov pa roj carbon dioxide nyob rau sab nraud.
Leukocytes yog cov tsis muaj xim nucleated uas tsis muaj cov duab tas mus li. Lawv yog cov yam ntxwv ntawm amoeboid txav. Nyob rau tib lub sijhawm, los ntawm phagocytosis, lawv neutralize cov kab mob pathogenic uas tau nkag mus rau hauv cov hlab ntsha thiab tsim kev tiv thaiv tib neeg.
Platelets nqa cov ntshav txhaws. Cov no yog cov hlau uas tsis muaj xim. Nrog lawv cov kev pab, ib tug complex enzymatic hloov dua siab tshiab ntawm fibrinogen protein nyob rau hauv nws daim ntawv insoluble yog nqa tawm. Yog li ntawd, lub cev tiv thaiv los ntawm kev poob ntshav ntau dhau, uas tuaj yeem ua rau muaj kev phom sij rau lub neej.
ntshav muaj nuj nqi
Lub neej tsis muaj ntshav tsuas yog ua tsis tau. Tom qab tag nrho, plasma (cov kua ib feem ntawm cov ntshav yog hu ua), ua ke nrog cov khoom tsim, ua kom lub cev ua pa ntawm cov kab mob nyob.
Lwm txoj haujlwm tseem ceeb yog muab zaub mov. Tom qab tag nrho, cov organic tshuaj los ntawm lub digestive channel mus rau hauv cov hlab ntsha, uas lawv twb thauj mus rau txhua lub cell. Txij li cov ntshav plasma yog cov tshuaj aqueous, nws koom nrog hauv kev tswj hwm homeostasis thiab lub cev kub tsis tu ncua. Cov kev tiv thaiv ntawm cov ntshav tuaj yeem suav nrog txhaws thiab tsim kev tiv thaiv.
Yog li, cov kua hauv cov ntshav hu ua plasma. Nws yog ib yam khoom intercellular uas tsim cov ntsiab lus nyob. Ua ke lawv ua kev thauj mus los, ua pa,excretory thiab ua pa ua haujlwm.
