Monga mbali madzi a m'magazi otchedwa?

Kumbukirani, monga gawo madzi a m'magazi otchedwa: maselo ofiira magazi, madzi a m'magazi kapena lymph? Wovuta kuyankha? Ndiye tiyeni tikumbukire pamodzi.

magazi Kodi

Kukhulupirira, koma mwazi - ndi mtundu wa minofu connective. Ndipo ziri zophweka zokwanira kutsimikizira. Magazi imakhala gawo madzi ndi maselo a magazi. Choyamba ndi chinthu intercellular. Ake kwambiri ndithu, kotero onse a mkati zimakhala chilengedwe ndi lotayirira ndi kupanga maziko a thupi. maselo A magazi - ndi maselo zimapezeka izo. Iwo akutchedwanso zinthu anapanga.

Madzi a m'magazi madzimadzi ndi chilengedwe mkati

Mbali madzi a m'magazi otchedwa plasma. uliri wa loitanirana ndi thupi katundu kwakukulukulu kudziwa ntchito ya mtundu wa minofu. Izi madzi chikasu, lomwe lili ndi kukhuthala kwambiri chifukwa kukhalapo m'menemo mapulotini corpuscles. cholowa mu magazi ndi pafupifupi 60%.

Milieu intérieur - magazi, lymph, interstitial madzimadzi. Madzi ndi chikhalidwe zofunika pakutchulidwa njira zovuta mankhwala kaphatikizidwe ndi pogawanikana pamawere wothandizila ndi mayendedwe awo mwa thupi.

Mipweya ya madzi a

Mbali madzi a m'magazi otchedwa plasma ndipo ndi chinthu intercellular. 90% tichipeza madzi. Yotsatira kenako kuchuluka kwa mapulotini, mlingo umene ukufika ku 8%. Izi fibrinogen, albumin ndi globulins. mapulotini izi kupereka madzi kuwombola ndi humoral chitetezo chokwanira kusamutsidwa mahomoni zonse kuthamanga osmotic.

Anaiwononga mu madzi a m'magazi zinthu zina organic. Chakudya zimapanga 0,12% ndipo ngakhale zochepa za mafuta - 0,7%.

Maminolo zigawo za madzi a m'magazi amene timapemphera salt. zinthu izi muli mawonekedwe a particles mlandu. Izi cations sodium, magnesium, potaziyamu, calcium, chitsulo ndi mkuwa. Pakuti particles zoipa mlandu ndi zotsalira za enaake, carbonate, phosphoric ndi zidulo zina mchere. A udindo wapadera mwa zinthu izi ndiye njira thupi. wokhutira ndi madzi nthawi zonse ali pa mlingo zonse. Izi sodium kolorayidi njira mu madzi, mmene mchere ndende ndi 0,9%. Pa nkhani ya imfa ya magazi ntchito kuchepetsa voliyumu chinkafuna. Izi ndi zofunika kwambiri makamaka pa nthawi imene sikutheka kukhazikitsa gulu ndi RH chinthu munthu amene akufunika thandizo kuchipatala.

maselo magazi

40% ya magazi amapanga zinthu mphako aliyense fomu imene amakhala ndi dongosolo yeniyeni ndi ntchito. Mwachitsanzo, maselo ofiira - wofiira biconcave chimbale mawonekedwe. Maselo amenewa ali nyukiliya ufulu ndiponso ali hemoglobin. Waukulu ntchito maselo a magazi ndi kuwombola mpweya. Iwo kunyamula mpweya wochokera ku mapapu kuti iri yonse yochepetsetsa ya thupi, komanso mpweya woipa mu njira iwowo.

Leukocytes ndi colorless nucleated maselo amene alibe mawonekedwe nthawi zonse. Iwo yodziwika ndi kayendedwe amoeboid. Choncho iwo n'chongoletsa tizilombo toyambitsa matenda ndi phagocytosis wa particles otsekeredwa mu magazi ndi kupanga chitetezo chokwanira munthu.

Othandiza kunyamula magazi clotting. Izi anamaliza mbale colorless. Mothandizidwa awo anagwira enzymatic mapuloteni zovuta kutembenuka kwa fibrinogen mu mawonekedwe ake insoluble. Chifukwa, thupi zimatetezedwa ku imfa kwambiri magazi, zimenezi kufa.

ntchito magazi

moyo wa munthu popanda magazi sangathe. Pambuyo pa plasma (mbali madzi a m'magazi otchedwa choncho) pamodzi ndi zinthu mawonekedwe imapereka mpweya wa zamoyo.

Ntchito inanso yofunika ndi kupereka mphamvu. Pambuyo nkhani organic akubwera kuchokera njira m'mimba mu magazi, amene kale amapezeka yonyamula iwo yonse yochepetsetsa. Popeza madzi ndi amadzimadzi, izo nawo kukhalabe homeostasis ndi kutentha zonse thupi. Ndi ntchito zoteteza magazi mwina mulinso kungomanga ndi mapangidwe chitetezo chokwanira.

Motero, mbali madzi a m'magazi otchedwa plasma. Ndi chinthu intercellular, imene pali mphako zinthu. Pamodzi iwo akuchita zoyendera kupuma, excretory ndi ntchito kupuma.
