Lub biochemical muaj pes tsawg leeg ntshav

Ntshav - ib lom kua uas muab nruab nrog cev thiab cov ntaub so ntswg nrog cov as-ham thiab oxygenic. Ua ke nrog cov qog system nws cov ntaub ntawv ib tug circulating nyob rau hauv lub cev. Nws ua ib tug xov tooj uas tseem ceeb heev functions: noj haus, excretory, kev tiv thaiv, ua pa, neeg kho tshuab, ntxawg, kub tswj.

Muaj pes tsawg leeg ntawm tib neeg cov ntshav mas nws txawv considerably nrog lub hnub nyoog. Nws yuav tsum tau hais tias cov me nyuam yog khaus heev metabolism, yog li lawv lub cev nws loj npaum li cas nyiaj rau ib 1 kg ntawm lub cev hnyav piv rau cov neeg laus. Nyob rau nruab nrab, ib tug neeg laus txog tsib los sis rau litres ntawm no lom kua.

Muaj pes tsawg leeg muaj xws li ntshav ntshav (kua feem) thiab tsim ntsiab (erythrocytes, leukocytes, platelets). Lub concentration ntawm cov ntshav liab nyob ntawm nws cov xim. Cov ntshav yog devoid ntawm protein (fibrinogen) yog hu ua ntshiab. Qhov no lom kua muaj ib tug me ntsis alkaline ras txog.

Lub biochemical muaj pes tsawg leeg ntawm cov ntshav - tsis systems. Lub hom ntshav buffers xws li bicarbonate (7% ntawm tag nrho cov loj), phosphate (1%), protein (10%), hemoglobin thiab oksigemoglobinovaya (rau 81%) thiab acidic (txog 1%) ntawm lub cev. Nyob rau hauv ntshav yeej los ntawm bicarbonate, phosphate, protein thiab acid nyob rau hauv cov ntshav liab - hydrogen carbonate, phosphate, cov qe ntshav liab - oksigemoglobinovaya thiab acid. Muaj pes tsawg leeg acidic tsis system muaj cov organic acids (acetate, lactate, pyruvic, thiab lwm yam) thiab lawv cov ntsev nrog muaj zog bases. Qhov tseem ceeb tshaj yog hydro thiab hemoglobin tsis system.

Cov tshuaj nyob tus yeees ntawm cov ntshav. Ntshav yog yus muaj los ntawm qhov tshuaj nyob tus yeees. Cov ntshav yog 55-60% ntawm tag nrho cov ntshav ntim thiab 90% ntawm cov dej. Khib nyiab comprise organic (9%) thiab mineral (1%) ntawm cov khoom. Organic yooj yim tshuaj yog cov nqaijrog, feem ntau ntawm uas yog tsim nyob rau hauv lub siab.

Lub protein muaj pes tsawg leeg ntawm cov ntshav. Tag nrho cov protein cov ntsiab lus nyob rau hauv cov ntshav ntawm cov tsiaj yog hom twg los ntawm 6 mus rau 8%. Muaj txog ib puas thiab protein Cheebtsam ntawm ntshav. Lawv yuav tsum tau muab faib ua peb feem: albumin, globulin thiab fibrinogen. Ntshav cov nqaijrog, uas tseem tom qab qhov kev tshem tawm ntawm fibrinagena hu ua ntshav ntshiab proteins.

Albumins yog muab kev koom tes nyob rau hauv cov thauj ntawm ntau cov as-ham thiab biologically active tshuaj (carbohydrates, fatty acids, vitamins, inorganic ions, bilirubin). Muab kev koom tes nyob rau hauv cov kev cai ntawm cov dej thiab mineral metabolism. Ntshiab globulins raug sib cais rau hauv peb cov zauv feem alpha-, beta- thiab gamma-globulins. Globulins thauj fatty acids, steroid cov tshuaj hormones, fat-soluble vitamins, yog tiv thaiv kab mob lub cev.

Cov carbohydrate muaj pes tsawg leeg ntawm cov ntshav. Cov ntshav muaj monosaccharides (qabzib, fructose), glycogen, glucosamine monosaccharides phosphates thiab lwm yam intermediate khoom ntawm carbohydrate metabolism. Lub ib thooj ntawm carbohydrates sawv cev los ntawm qabzib. Qabzib thiab lwm yam monosaccharides nyob rau hauv cov ntshav ntshav nyob rau hauv dawb thiab protein-ua txhua yam lub xeev. Cov ntsiab lus ntawm txuas zib nce mus txog 40-50% ntawm tag nrho cov carbohydrate cov ntsiab lus. Cov carbohydrates intermediate metabolic khoom lactate zoo tu qab tso acid, cov ntsiab lus ntawm uas tsub kom sharply tom qab hnyav ib ce muaj zog.

Cov piam thaj concentration yuav varied nyob rau hauv ntau cov kab mob kas. Cov tshwm sim ntawm hyperglycemia cov yam ntxwv ntawm cov ntshav qab zib, hyperthyroidism, poob siab, tshuaj loog, ua npaws.

Lub lipid muaj pes tsawg leeg ntawm cov ntshav. Cov ntshav muaj txog li 0.7% thiab ntau lipids. Lipids yog nyob rau hauv dawb thiab protein-ua txhua yam lub xeev. lipid concentration nyob rau hauv cov ntshav hloov nyob rau hauv lub pathology. Piv txwv li, nyob rau hauv tuberculosis, nws yuav ncav cuag 3-10%.

Ntshav roj cua. Qhov no biofluid comprises Pa (oxygen), carbon dioxide thiab Nitrogen nyob rau hauv lub dawb thiab khi lub xeev. Yog li, piv txwv li, hais txog 99,5-99,7% nrog rau oxygen txuam nrog hemoglobin, thiab 03-0,5% yog nyob rau hauv lub dawb lub xeev.
