Hemodynamics a me physiology o ka carotid arteries

Ke anatomical 'ole o ka aortic e pio kūikawā, no ka mea, o ka elasticity o na moku koko. Lālau aʻela ia i kekahi o ke koko o kona lumen, ka carotid arteries lawe ia a hiki i ke poo. Kahi o 25% o cardiac auaiaea e hina ma ka lolo'aʻaʻa, a wehewehe i ka kiʻekiʻe caliber o ka carotid arteries. Once ka naau o ka mea e hiki mai ana hapa o ka ka ho'ēmiʻana kipaku koko i loko o ka aorta, loaa ia he hapaha ka mea.

I wahi o ka papa o ka mea pono carotid artery i loko o kekahi 'hoʻonaʻauao mau loaʻa, a ua kapaʻia he mea poepoe Pule Hoola. Kēia wahi ma ke kanaka ai, ma ka carotid artery ua aia ma ka luna kihi o ka laryngeal thyroid cartilage. Ua loaʻa he nui helu o receptors, a me kaʻike ākea hoailona loulou, hōʻikeʻana i ka hana ana o ka naau. Inā cardiac auaiaea mea uuku, no ka mea loaʻa'ōnaehana uaʻike piʻi i ka hōʻemi iki puʻe, a pela stimulates ka vasomotor waena. Inā ka puʻe i loko o ka arterial kahi moe mea kiʻekiʻe, ka paʻa manaʻo.
