Hemodynamics le popego ya methapo carotid

Sebopeho anatomical tsa aortic Arch khethehileng, kaha e ke elasticity ea methapo ea mali. Ho nka ba bang ba mali a lumen eona, carotid methapo jara ho hlooho. Hoo e ka bang 25% ea khumo cardiac oela boko dinama tse nyenyane tse, e leng e hlalosa ka caliber phahameng tsa methapo carotid. Hang pelo ea karolo e latelang ea phokotso ea leleka mali ka aorta, ba ile ba fumana e le kotara.

Sebakeng sa ho makala a ba tloaelehileng carotid mothapo thutong e 'meli e itseng e fumaneha, eo ho thoeng ke bolo tšoeroe ke boroko. sebakeng sena ka molala batho, moo mothapo carotid e teng ka bohale ka holimo ea laryngeal thyroid lefufuru.
