Pākīpihi a me nā pahūnū
Hoʻokomoʻia nā'alepona tricuspid a me nā'aleleke he'elventricular, no ka mea, aia lākou ma waena o nā'āpana a me nā ventricles i ka'ākau a me ka hapa hema o ka puʻuwai. He mauʻaha pili lōʻihi lākou a ua uhiʻia me endocardium - he'ōwili lahilahi e paʻa ana i kaʻaoʻao o ka naʻau. ʻO ka ma luna o nā mālia he maʻemaʻe, a ma kaʻaoʻao lalo he mau loulou pili pono e pili ana e kau i nā pepa. ʻO ka māmā tricuspid heʻekolu ukali, a heʻelua valves (a kapaʻiaʻo ia he bivalve). Loaʻa ka inoa o ka pulve valve no ka like like me ke kāwili o ka bishop.
ʻO ke kuhuma o ka wāwae pulmonary
Ke kuhi nei ka pulveary valve i ka puka o ka pahu pulmonary mai ka ventricle pono. ʻO ke kīʻaha pulmonary e lawe i ke koko mai ka puʻuwai i nā māmā. Aia ma luna o nā'ōmole o ka pulmonary loga, kahi kīʻaha liʻiliʻi piha i ke koko a pale i ka piliʻana o nā kaula i ka paia o ka pahu kōmā i ka wā e weheʻia ai ka valve. I ka wā o ka systole o ke kaiapuni, ke holo nei ke koko ma loko o nā'alea wahaheʻe a me nā pahūnele niho i loko o ka ventricles. I ka wā o ka systole o nā ventricles, hiki i ka piʻiʻana o ka hopena i ka hopena o nā pahū o nā kauwela. Mālama kēia i ka hoʻihoʻiʻia o ke koko i ka atria. Hoʻopiliʻia nā pāhapa Valve e nā loea,ʻaʻole lākou e hiki iā lākou e wehe i ke kaomi i loko o ka ventricles. Ma hope o ka pauʻana o nā pahūwaena o nā wāwae, hiki i ke koko ke hele i loko o nā hiʻona maʻamau i loko o ke kāpuni pulmonary a me ka aorta. Hoʻouluʻia nā kīnā o nā māmā no ka ikaika nui o ka ventricles a e hāʻule ana i ka wā e pau ai ke pūnaha a hoʻomaka ke diastole.
Hana Hana
Me ka phonendoscope, hiki iāʻoe ke lohe e pili pū ana nā naʻau a pau me keʻano o nā leo naʻauʻelua. ʻO ka leo mua ke hōʻikeʻia i ka manawa o ka pauʻana o nā valves o ka wā kahiko, aʻo ka lua - i ka manawa o ka hoʻopauʻana i ka valve o ka hana o ka pulmonary valve. Hiki i nā liona mai nāʻaoʻao a me ka lalo lalo o nā kaulawa o nā māmā valve a me nā maneho, a laila ua alakaʻiʻia lākou i lalo a pili i nā mīhini papillary e hele i loko o kaʻaha makani.
ʻO ke kulekele o ka hana o nā bele
Kōkuhi e hōʻole i ka hoʻololiʻana o nā valve o nā valves atrioventricular i loko o kaʻanuʻu atrial under the action of high blood pressure during ventricular systole. Hoʻopiliʻia lākou i nā vili e pili ana, kahi e hoʻopaʻa ai i ka paʻa i ka wā o systole ventricular a hikiʻole ke kahe o ke koko i ke kumu. Ke kapaʻia nei ka valve a me ka pulveary arc valve i ka hapalua. Aia lākou ma ke ala o ke koko mai ka puʻuwai a pale i ke hoʻiʻana o ke koko i ka ventricles i ka diastole. ʻO kēlā me kēia mau pahuwaʻelua he hapa i hoʻohālikeʻia i ka hapalua mahina, e like me nāʻeke. Aia lākou i loko o ka lole pili a ua uhiʻia me ka endothelium. ʻO Endothelium ka maʻalahi o nā kaula.
