Masero ari mumuviri womunhu Vangani? Ndeapi kukosha?

Chii chinozivikanwa pamusoro womunhu? Vangani masero ari mukuru womunhu muviri? Zvavakanga akure, zvavari? Munyika, masayendisiti ari kuedza kugadzirisa Puzzles izvi.

Chii foni?

Masayendisiti vari kudzidza chirimwa Utachiona, mhuka, vanhu. Keji - This iduku chikamu chipi muviri. In muviri pane zvakawanda kupfuura matiririyoni 100.. The nhamba yacho chaiyo haizivikanwi. Vangani masero ari mumuviri womunhu ari kufa zuva? Mari inoenderana inozoshandisirwa kushandiswa. Somuenzaniso, muna intestinal epithelium - 70 bhiriyoni pazuva, ropa - 2 bhiriyoni, uye tsinga masero regai panoda pashure pokufa.

Kokutanga kwamakamuri inowanikwa 1665 Robert guk. Akaziva kuti vakuru munhu, zvikuru izvi STRUCTURAL zvinhu mumuviri wake. , потому что они отмирают и рождаются ежеминутно. Hazvibviri nhamba masero ari mumuviri womunhu, nokuti vanozvarwa uye kufa miniti ose.

Mamiriro uye basa

Hatigoni kutaura zvakawanda pamusoro masero ari mumuviri womunhu, asi masayendisiti ziva kuti havana kunzwisisa maumbirwo. Most ine:

• Musimboti, inonzi masero mwoyo;
• cytoplasm;
• nucleolus;
• mitochondria;
• Musimboti deko;
• endoplasmic reticular inotungamirwa;
• ribosomes;
• lysosomes;
• Makomba uye pores;
• Sero Kamudzira, izvo zvinoita kuvimbika, inodzora intracellular nomwero.

The mabasa chokuita kwetunhu zvinhu. masero Glandular pave mahormone kana makemikari. The mammary mumasero kubereka mukaka, rwatata - jekiseni. Vamwe regai synthesized, eg tsandanyama masero.

Pasinei vangani masero ari mumuviri womunhu, havagoni kurarama ndisina. Masero vari wezvidimbu zvinhu muviri chete.

masero eropa

Chezvakanaka nemvura inoyerera kuburikidza mutsinga vanhu? Rine plasma uye cellular zvinhu:

• masero matsvuku eropa - red ropa masero;
• maplatelet;
• chena masero eropa - chena ropa masero.

Dzavo kugutsikana kunobva arambe achirema uye ruvara ropa. It anoita kuchinjwa makemikari ari mumuviri. кровяных клеток. muviri mukuru kuti ropa masero anenge mabhiriyoni 50. Zviri pamusoro 5.5 litres.

ruvara masero

Melanocytes mumuviri womunhu anokonzera sedare ganda, bvudzi, maziso uye dzimwe nhengo dzomukati. masero kwakadaro ane mukati cytoplasm pigments, zvichikonzera zvavanoita. Melanocytes uyewo kuita rwokudzivirira basa pamusoro UV mwaranzi vane basa kusukuta matehwe. Masero ari mhando Woody.

The mumasero tsinga

Uyu ndiwo mumwe wevaya kuti hazvigoni kudzorerwa shure kwekufa. zita ravo dzesayenzi - Tutsinga tunofambisa mashoko utwu. basa ravo - kuti ribude nekufambisa mashoko zvemagetsi pulses zvinoberekwa navo. Tutsinga tunofambisa mashoko utwu akakamurwa marudzi akawanda:

• kutsinga dzinouya (anokonzera maitiro chiedza, ruzha);
• motokari;
• interneurons.

The maumbirwo rinosanganisira muviri sero, dendrite, axon. Maererano mamiriro avo, ivo vari rakakamurwa mapoka akawanda. The huta hwevanhu hurongwa rine anenge mabhiriyoni 10 Tutsinga tunofambisa mashoko utwu. Gore negore vanenge 10,000 kufa uye handichisiri akapora. Mukuru wacho, kashoma mapfupa.

Camadas masero

Vangani masero mumuviri vane basa kubereka? Vane mhando mbiri, ivo rakakamurwa varume - dzisingaoneki - nemukadzi - zai. Male dzokubereka Sero saizi iri yakakura zvikuru kupfuura nehadzi, sezvo rine mukuru yakawanda cytoplasm. Vakanga kutanga yakawanikwa 1677, asi mashoko okuti pachavo aonekwa kwezana remakore rechi19.

Nepo hazvibviri kutaura chaizvo zhinji masero mumuviri womunhu, vatsvakurudzi akatarisa zvinenge zvose zvipenyu dzavo. yavanopedza kwakabatana zvakananga kuvapo zvose upenyu Panyika. Masayendisiti ari kuedza kudzidza sei kukura masero dzevanhu pakutsvakurudza mumarabhoritari. Zvichida ivo uchabudirira.
