Chomaliza pakhomo mpweya inspiratory

Pamene mpweya umalandira alveoli, izo ojambula maukonde thinnest Mitsempha - capillaries m'mapapo mwanga. Erythrocytes (maselo ofiira) mukhoza kudutsa capillaries ndi chimodzi chokha, kotero yopapatiza diameters. Kudzera thinnest khoma (0.5 mm) mpweya woipa umadutsa mu alveolus lapansi. Mpweya masamba alveoli, pokhala chosakanikirana ndi maselo ofiira.

Only atatu kotala ya yachiwiri maselo ofiira magazi amakhalabe capillaries lapansi. Panthawi imeneyi yochepa mpweya ndi mpweya ndi nthawi swapped. Zimenezi chodabwitsa kuwombola mpweya wotchedwa mayamwidwe. Magazi apindula ndi mpweya akulowa mitsempha m'mapapo mwanga ndipo kenako kumanzere kwa mtima, ndipo kuchokera kumeneko amawapopa thupi lonse.

Tangoganizani magazi yonse muyenera yokha kuti anapatsidwa kwathunthu lamavutoli kupuma kulandirana zonse!
