Arteries of pulmonary circulation
肺循环的动脉
Pulmonary trunk 肺动脉干 • Arises from right ven
tricle • Runs up, back ,and to
the left • Bifurcates inferior t
o aortic arch into ri ght and left pulmonar y arteries, one for e ach lung
• Consist of four chambers (r ight and left atria, right and left ventricles)
• Artery 动脉 a. carry blood away from the hear t
• Veins 静脉 v. carry blood back to the heart
• Celiac trunk 腹腔干 • Superior mesenteric a.
肠系膜上动脉
• Inferior mesenteric a.
肠系膜下动脉
Parietal branches

Organization
• Heart 心
• A muscle pump to maintain t he flow of blood,
Abdominal aorta 腹主动脉
Visceral branches 脏支
• Paired branches
• Middle suprarenal artery
肾上腺中动脉
• Renal artery 肾动脉 • Testicular (ovarian) art
ery 睾丸（卵巢）动脉
• Unpaired branches
• Run on flexor surfaces
• Usually do not pass dire ctly through muscles, av oiding compression
• Together with the veins an d nerves in a sheath of fa scia to form neurovascular bundle 血管神经束
• Capillary 毛细血管microscopic v essels, the area of exchange b etween blood and tissue fluid
