Chii chinoratidza chimiro masero? sero chimiro

Nhasi tichakurukura mubvunzo: "? Chii chinoratidza sero chimiro". Chokutanga, tinoona kuti muviri wedu rinoumbwa zvachose masero nomumwe. Uye zvose dzedu dzomukati uye zvimwewo zvomukati - ndiye constructor, rokuti mitezo iyo - sero duku, tinogona kuona chete nemaikorosikopu.

Chii chinoratidza chimiro masero? Pano unogona kusarudza zvinhu zvinoverengeka, izvo tichaita kunyora gare gare. Chokutanga tinofanira tinyatsoziva marongerwo (nemamiriro) muchitokisi. Zvinokosha kuziva chokwadi kuti vose inogona kupatsanurwa muzvikwata:

• muriwo;
• mhuka;
• Mabhakitiriya masero.

Tichaongorora mumwe mhando yoga.

chitokisi

Zvose zvipenyu nezvinhu zvakatipoteredza rinoumbwa masero, izvo uri mhango takapoteredzwa membrane. nzvimbo iyi mukaha izere nemvura uye kuramba mhinduro, yakavakirwa - mvura.

Saka tinogona kutaura: Sero - inokosha Unit, havagoni chete kuumba zvakawanda, asi kuvapo tisingatungamirirwi. Vane dzinoverengeka zvinhu zvakadai:

• muviri;
• kuvapo vayo;
• nokuzvidzora kubereka;
• budiriro.

Zvakakosha kuziva kuti vanogona zvitarisiko siyana uye hukuru. Chii chinoratidza pezvakaita pamakamuri, isu ichaongorora pashure kuziva mamiriro avo. Cell, sezvinoita zvose zvipenyu zvinhu yedu yakavepo, isu hatingazvirumbidzi nezvazvo nedanho yokutendeutsa, uye ane ano Kutarira mugumisiro.

mamiriro

Pasinei chokwadi kuti sero chimiro, ukuru uye rwendo kungava kusiyane, vane fananei marongerwo. Ziva zvakafanana STRUCTURAL dzakabatana:

• muchitokisi Kamudzira;
• cytoplasm;
• core.

Ndiko, kune vatatu STRUCTURAL dzakabatana, iyo inogona kuwanikwa kakawanda. Zvisinei, pane kunze. Tora tsandanyama, masero awo akaumbwa Kamudzira, cytoplasm, uye vakawanda cores. Zvino takaona muenzaniso kana vakachengeta muchitokisi chete akawanda cores, asi pane kushayikwa wavo wakakwana. Muenzaniso wechipiri musimboti kungava erythrocyte. Ekupedzisira havana sezvo vazhinji zvinhu uye zvinogonekwa, saka hazvibviri kuti nokuzvidzora vandudzai uye tinobereka (nekuti pasina neerekitironi riri kuchengetwa).

Zvakakosha kuziva uye chii protoplasm. commonality ino neerekitironi cytoplasm. Zvino tichati ongororei chii inoshanda anoitwa mumwe chezvinonhuwira muchitokisi. The Kamudzira anoshanda anonyanya chipingamupinyi basa unoravura protoplasm ari kupinda pakati vasingadiwi zvinhu.

The cytoplasm afanane mondo uye inoumbwa zvitatu zvinoti:

• hyaloplasm;
• organelles;
• inclusions.

It cytoplasm ndiye anokonzera rinokosha sero pezvakaitwa: muviri, simba uye ruzivo exchange.

Pakati zvose tsanga mabasa ndedzinotevera: mutemo muviri, RNA usage, kuchengetwa uye kupararira magene mashoko.

shepi

Chii chinoratidza chimiro masero? chinangwa chavo - ndiye wokutanga uye mukuru. Muchikamu chino, isu pfungwa zvichibvira kusarudza. Asi zvisati kuti zvinokosha kuona hukuru zvavo, izvo uyewo yakasiyana chaizvo. Somuenzaniso, vamwe utachiona vane saizi vanenge 0.2 microns. Kana mumwe anoziva 1 micron vakaenzana mumwe kuzviuru 1 mm. Sero akadaro haichaonekwi pamwe kusimira ziso, asi panewo kurei mienzaniso (huku zai, zvihuta, nemhou zvichingodaro). Kutaura zvazviri - ari muchitokisi chimwe chete, uye miganhu yacho kusvika 18 masendimita pakureba.

Tinosiyanisa mamwe marudzi:

• bhora;
• polyhedron;
• nyeredzi;
• humburumbira uye zvichingodaro.

Munoonaka, pane siyana maumbirwo uye hukuru kwamakamuri. Nyore chimiro lymphocyte - bhora, mumwe polyhedron protrude hepatocytes (chiropa masero), nyeredzi - osteoblast (pfupa rinenge) uye zvichingodaro.

chirimwa masero

Form chirimwa masero nguva ndiwo chete, asi mhuka inozviisa kuchinja. Plant kuva goko hwakasimba kuti haabvumiri kuti rokuchinja.

Dimensions yemanyorero siyana pakati 10 uye 100 microns (kukura rokumusoro chirimwa masero). Asi pane masero yakakura, vari kushandiswa mumatanda nezvinovaka muviri uye mvura. Ava mbatatisi tubers kana dzine zvibereko. Tinogona kuona navo akashama masero ziso ndimu pulp, visi kana orenji, sezvo pakukura kwavo - a millimeters shoma. Vamwe fibers (furakisi, yorukato) kusvika kureba 80 millimeters.

masero mhuka

Zvino isu anofanira ongororei Zvekare zvimiro zvemhashu uye hukuru nemasero mhuka. Zvakakosha kuziva kuti vane siyanei chivako pane romuriwo. Enzanisa mapikicha kare, uye chikamu ichi. Kazhinji, masero mhuka akanyatsojeka diki (anenge 50 microns). Saka, vanofanira kuva vakadzidza nemaikorosikopu. Shapes uye hukuru akasiyana chaizvo. Somuenzaniso:

• tsandanyama Sero - elongated chimiro;
• eropa - denderedzwa chimiro;
• Skin masero - sandara kana mukombe serin'i chimiro.

masero kwemabhakitiriya

Takatoona akafukidzwa siyana mhuka uye chirimwa masero, asi Zvinoonekwa masero kwemabhakitiriya? Mabhakitiriya All inogona kupatsanurwa muzvikwata (muchimiro):

• idenderedzwa;
• tsvimbo;
• crimped.

Unogona kuona mimwe mienzaniso mumufananidzo dzaitaurwa chikamu. Mabhakitiriya chaizvo mupfupi, masero aya anogona chete kuonekwa pasi kumusoro magnification maikorosikopu.
