Pastga yo‘naluvchi aorta (aorta descendens) aortaning eng uzun qismi bo‘lib,
arcus aortae dan IV Ko‗krak umurtqasi oldida boshlanib, mediastinum posterius
orqali diafragma teshigidan qorin bo‘shlig‗iga tushadi va bel umurtqasining oldiga
kelganda ikki katta tarmoqqa bo‘linadi.
Aorta descendens ning Ko‗krak bo‘shlig‗ida joylashgan bo‘lagi aorta thoracica
(Ko‗krak aortasi) deb ataladi va undan Ko‗krak bo‘shlig‗ining devoriga (ramus
parietalis) va Ko‗krak bo‘shlig‗ida joylashgan a‘zolar uchun rami viscerales
tarmoqlari chiqadi.
