Hauv duodenum, plab hnyuv acid yog neutralized los ntawm sodium bicarbonate. Qhov no tseem thaiv plab hnyuv enzymes uas muaj lawv cov optima nyob rau hauv lub acid ntau ntawm pH. Kev tso dej ntawm sodium bicarbonate los ntawm cov txiav txiav yog ua los ntawm secretin.
Hauv qhov no, lub luag haujlwm ntawm HCl hauv koj lub plab yog dab tsi?
HCl yog ib ntawm gastric kua txiv secreted los ntawm plab . HCl hloov cov enzyme tsis ua haujlwm pepsinogen rau hauv nws daim ntawv nquag pepsin. Pepsin zom cov protein thiab zom lawv rau hauv cov amino acids. HCl tseem tua cov kab mob phem los yog cov kab mob hauv peb zaub mov thaum nws ncav cuag lub plab los ntawm txoj hnyuv plab.
Tsis tas li, HCl tsoo cov zaub mov li cas? Cov hydrochloric acid hauv plab kua txiv tawg cov zaub mov thiab cov zom zaub mov zom cov protein. Cov kua qaub kua qaub kuj tua tau cov kab mob. Ua ke nrog cov bicarbonate, qhov no ua kom lub plab phab ntsa nws tus kheej tsis puas los ntawm cov hydrochloric acid.
Ntawm no, yuav ua li cas thaum lub plab acid neutralized?
Proper digestion nyob rau hauv lub plab tau xwb tshwm sim hauv qhov nqaim pH ntau, thiab thaum peb neutralize plab acid , cov nyhuv domino raug pov tseg. Cov plab yog acidic heev thiab zom cov zaub mov mus rau hauv ib qho ntxiv acidic paste hu ua chyme.
Puas yog HCl hauv plab concentrated?
Thaum stimulated, parietal hlwb secrete HCl ntawm a siab ntawm kwv yees li 160 mM (sib npaug rau pH ntawm 0.8). Cov kua qaub tau tso rau hauv cov cannaliculi loj, kev sib sib zog nqus ntawm cov ntshav ntshav uas txuas ntxiv nrog lumen ntawm plab.

Dab tsi yog qhov nruab nrab nruab nrab txhim kho rau?
Thaum lub sijhawm embryonic kev txhim kho, lub nruab nrab lub paj hlwb (tseem hu ua mesencephalon) tshwm sim los ntawm ob lub vesicle ntawm cov hlab ntsha neural, thaum sab hauv ntawm lub raj no dhau los ua lub paj hlwb. Nws tsis faib mus rau lwm qhov chaw hauv hlwb
Qhov nruab nrab nyob nruab nrab txhais li cas?
Medial hais txog txhua yam mus rau nruab nrab ntawm lub cev. (Qhov tsis sib xws yog ib sab.) Qhov sib thooj hais txog lub ntsiab lus ze rau qhov taw tes siv. (Qhov sib txawv yog nyob deb.) Peripheral hais txog txhua yam uas nyob deb ntawm qhov chaw thiab paub qhov sab ntug ntawm yam
Qhov nruab nrab nruab nrab ntawm tus ncej puab ua dab tsi?
(Qhov nruab nrab nruab nrab yog nyob hauv nruab nrab txoj cai.) Qhov nruab nrab nruab nrab ntawm tus ncej puab yog ib qho ntawm fascial compartments ntawm tus ncej puab thiab muaj lub duav adductor nqaij thiab cov leeg gracilis. Lub paj hlwb obturator yog thawj lub paj hlwb muab cov khoom no. Obturator artery yog cov ntshav xa mus rau tus ncej puab nruab nrab
Dab tsi yog qhov txawv nruab nrab ntawm lub plab plab thiab lub plab zom mov?
Cov plab hauv plab yog qhov tsis txaus ntseeg hauv lub plab uas qhia txog kev nkag mus rau 3-5 tubular zoo li lub plab hnyuv. Lawv tob hauv cov pylorus dua li lawv nyob hauv lwm qhov ntawm lub plab. Tib neeg lub plab muaj ob peb plhom ntawm cov qhov no uas teev rau saum npoo ntawm daim tawv nqaij epithelium
Vim li cas cov hlab ntshav nruab nrab nruab nrab siv rau venipuncture?
Nws muaj feem cuam tshuam nrog chaw kho mob raws li nws tau siv tas li rau venipuncture (noj ntshav) thiab ua qhov chaw rau txhaj tshuaj cannula. Nws txuas cov basilic thiab cephalic leeg thiab ua qhov tseem ceeb thaum siv lub siab. Nws nyob hauv qhov cub fossa superficial mus rau kev ua haujlwm aponeurosis
