Sila, ki omogoča prehajanje plinov, je razlika med <a href="/wiki/Delni_tlak" title="Delni tlak">delnimi (parcialnimi) tlaki</a> respiracijskih plinov v alveolnem zraku in mešani venski krvi na začetku pljučnih kapilar. Ko pride mešana venska kri v pljučne kapilare, se začne izmenjava plinov med krvjo in zrakom v mešičkih. Količina plina, ki preide skozi alveolokapilarno membrano, je odvisna od velikosti gradienta tlaka, fizikalno kemijskih karakteristik opazovanega plina (<a href="/wiki/Topnost" title="Topnost">topnost</a> v <a href="/wiki/Ma%C5%A1%C4%8Doba" class="mw-redirect" title="Maščoba">maščobah</a>, velikost plinskih molekul itn.), velikosti površine alveolokapilarne membrane, kakovost alveolokapilarne membrane (debelina, sestava), količine <a href="/wiki/Hemoglobin" title="Hemoglobin">hemoglobina</a> v kapilarni krvi, ki je sposoben sodelovanja pri plinski izmenjavi, in velikosti pretoka krvi prek pljučnih kapilar. Brez funkcionalnega hemoglobina bi bila izmenjava respiracijskih plinov med alveolnim zrakom in krvjo zelo nizka, saj se kisik in ogljikov dioksid le v majhnem delu raztapljata v krvi in vezava na hemoglobin je bistvena. Koncentracije plinov se med zrakom v mešičkih in krvjo izredo hitro izenačijo, tako da so praktično že na polovici pljučne kapilare delni tlaki respiracijskih plinov v kapilarni krvi in alveolnem zraku enaki. Meja izenačitve se pomika proti koncu kapilare, če se pretok v pljučni kapilari močno poveča.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> Iz alveolarnih kapilar se nato oksigenirana kri zliva v pljučne vene, po katerih potuje do <a href="/wiki/Srce" title="Srce">srca</a>.<sup id="cite_ref-Cebasek_2-1" class="reference"><a href="#cite_note-Cebasek-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Glej_tudi">Glej tudi</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Plju%C4%8Dni_me%C5%A1i%C4%8Dek&veaction=edit&section=3" title="Uredi razdelek: Glej tudi" class="mw-editsection-visualeditor"><span>uredi</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Plju%C4%8Dni_me%C5%A1i%C4%8Dek&action=edit&section=3" title="Urejanje izvorne kode razdelka: Glej tudi"><span>uredi kodo</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Plju%C4%8Dno_dihanje" title="Pljučno dihanje">pljučno dihanje</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Sklici">Sklici</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Plju%C4%8Dni_me%C5%A1i%C4%8Dek&veaction=edit&section=4" title="Uredi razdelek: Sklici" class="mw-editsection-visualeditor"><span>uredi</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Plju%C4%8Dni_me%C5%A1i%C4%8Dek&action=edit&section=4" title="Urejanje izvorne kode razdelka: Sklici"><span>uredi kodo</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="reflist" style="list-style-type: decimal;"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text"><a rel="nofollow" class="external free" href="http://lsm1.amebis.si/lsmeds/novPogoj.aspx?pPogoj=alveol">http://lsm1.amebis.si/lsmeds/novPogoj.aspx?pPogoj=alveol</a> <a rel="nofollow" class="external text" href="https://web.archive.org/web/20131110211202/http://lsm1.amebis.si/lsmeds/novPogoj.aspx?pPogoj=alveol">Arhivirano</a> 2013-11-10 na <a href="/wiki/Wayback_Machine" title="Wayback Machine">Wayback Machine</a>., Slovenski medicinski e-slovar, vpogled: 10. 11. 2013.</span> </li> <li id="cite_note-Cebasek-2"><span class="mw-cite-backlink">↑ <sup><a href="#cite_ref-Cebasek_2-0">2,0</a></sup> <sup><a href="#cite_ref-Cebasek_2-1">2,1</a></sup></span> <span class="reference-text">Čebašek V.
