Lesela phoofolo - hore na ke eng?

From masela akarelletsa lintho tse ea limela le liphoofolo lefatšeng. Ba fapaneng, 'me e mong le e mosa ea lesela o etsa mesebetsi ea eona.

Seo ke karolo lesela?

Ho tse nyenyane mehaho e le karolo ea 'mele ke seleng. Tsena, 'me a qapa mefuta eohle ea lisele - bobeli limela le liphoofolo.

sebopeho seleng ea

sebopeho sena se ka ba teng e le 'mele oa ka thoko. seleng e 'ngoe a ntse a hlahiswa tse kang libaktheria le protozoa eukaryotes. Sena se karolo ea e phelang phelang e na le likarolo tse joalo: lero la mali lera, cytoplasm, e emeloang tharollo colloidal, motheo le organelles - dibopeho ka ho sa feleng, e mong le e ba tse etsang mosebetsi itseng. Ka kaheho ea sele ka phoofolo eo ho na le organelles: setsi seleng, ribosomes, lysosomes, mitochondria, sethusathuto Golgi le endoplasmic reticulum. lisele tse dimela fapana ho tsona ka hore ba na le vacuoles (pele tse seng kae, 'me le botsofali ea lisele, ba kopane ka' ngoe e bohareng) le plastids: chromoplasts, leucoplasts le chloroplasts.

The lero la mali lera ea seleng ea phoofolo e na le dikarolo tse tharo: ya e 'meli protheine le lipid therebetween. khetla ena, le eena, e pota-potiloeng ke glycocalyx, e leng e entsoe ka polysaccharides, glycolipids, glycoproteins. Organelles phetha mesebetsi latelang: setsi seleng e - kabo ea chromosomes nakong fission, ribosomes - the tswakana ea lihaha-'mele, ho lysosomes - petsoha dintho le potlakisang tsebetso ea lik'hemik'hale, mitochondria - matla molokong o mong ka, Golgi sethusathuto - ho bokella le ho sokoloha dintho tse itseng, endoplasmic reticulum (reticulum) - lipalangoang tsa metsoako lik'hemik'hale. Palo ea ba bang organelles ka seleng e itšetlehile ka hore na ho ke ke e le karolo ea mofuta ofe kapa ofe oa lesela.

lisele sebopeho phoofolo

Phoofolo dinama tse nyenyane tse e entsoe ka lisele tse, ho kopantswe intercellular ntho. Ho itšetlehile ka sebakeng sa lesela, ho ka ba le sebopeho sa tšoaneng, joale ka tekanyo e khōlō kapa e monyenyane. Dinama tse nyenyane tse ka liphoofolo, ho na le mefuta e latelang:

• mateano;
• epithelial;
• tšohile;
• mesifa.

connective dinama tse nyenyane tse

Ba tlile ka mefuta e joalo: teteaneng le hlephileng fibrous, lefufuru, lesapo, mali le lisele tsa mmele, mafura, reticulum. Kaofela ha bona li tšoana ke kgolo palo ea lenaane-thalo le kantle ho sele. The le letšo-letšo fibrous dinama tse nyenyane tse e na le haholo-holo ea likhoele hlephileng faeba - ho tloha le boima amorphous. Bone o na le e kholo chelete ea tiileng ntho intercellular entsoeng ka metsoako lik'hemik'hale inorganic. Intercellular ntho ea lefufuru dinama tse nyenyane tse e na le lintho tse phelang. Lesela reticular kenyelletsa ditokiseletso lisele tse bakoang eo lisele tsa mali tse thehoa. The ho hlophisoa mali a le lisele tsa mmele akarelletsa kholo chelete ea mokelikeli. Sebōpeho sa mofuta ona wa dinama tse nyenyane tse phoofolo e entsoe ka lisele tse itseng, ba ile ba ba boetse o bitsoa le ka liseleng tsa mali. Mefuta bona:

• lisele tse khubelu tsa mali;
• leukocytes;
• liplatelete.

E mong le e ba bona ba etsa mesebetsi ea eona. Erythrocytes tse hlahisoang e le mehaho e chitja e nang le hemoglobin. Ba na le boikarabelo bakeng sa ho tsamaisa oksijene ho pholletsa le 'mele. lisele tse tšoeu mali phetha mosebetsi 'mele. Liplatelete ba ikarabellang bakeng sa ho hoama ha mali tabeng ea tšenyo e ea letlalo.

lisele Epithelial ea liphoofolo

epithelium e arotsoe ka mefuta e 'maloa:

• a bataletseng;
• dikhubu;
• cylindrical;
• ciliated;
• ame;
• glandular.

Squamous epithelium hlahisa lisele tse pantshisi-tse, eo na le sebōpeho sa dikhutlontsi. lesela Sena ke ka metso le ho nyanyana litho tsa botona cavity. Dikhubu epithelial dinama tse nyenyane tse ea liphoofolo lined le a liphio tubules, cylindrical - mala le mala, ciliated - Lufthansa, thetsana - the nasal cavity. Glandular karolo e litsoelesa. Lisele tsa dinama tse nyenyane tse ena e khethehileng, 'me a ho hlahisa li-hormone, lebese le lintho tse ling D..

mesifa dinama tse nyenyane tse

Ba ile ba boela ba arotsoe ka mefuta e 'maloa:

• mechato;
• boreleli;
• pelo.

The dinama tse nyenyane tse mesifa ya mefuta pele phoofolo ke karolo ea mesifa ea ea tsamaiso ea musculoskeletal. Tsa mesifa le boreleli la litho tse ka hare di thehoa, tse kang 'a mala, mala, popelo, joalo-joalo pelo e tšoauoa ka' nete ea hore likhoele tsa eona li lohellana le e mong le e nngwe - .. Ho lumella hore ba ikhule ka lebelo.

lisele methapo ea liphoofolo

mofuta ona wa lesela na le veretenopodobnyh, stellate, kapa lisele tsa chitja - methapo ea kutlo, le dintho intercellular - mesogloea eo e fana ka limatlafatsi tse ngata ho methapo ea kutlo e. Methapo ea kutlo bopilwe 'mele, e axon le dendrites - dithulaganyo ke eo lisele tse di amanang. Ba hlokahala bakeng sa pontšo ena.
