Aortic sac
Aortic sac
The aortic sac is an embryological structure that forms the initial segment of the aortic arches. It is a dilation of the truncus arteriosus, which is the embryonic precursor of the aorta and pulmonary artery. The aortic sac gives rise to the aortic arches, which in turn form the major arteries of the body.
Etymology[edit | edit source]
The term "aortic sac" is derived from the Greek words "aorte" meaning "that which is hung up," and "sac" from the Latin "saccus," meaning "bag" or "pouch." This refers to the sac-like structure of the aortic sac in the embryonic stage.
Development[edit | edit source]
The aortic sac develops from the truncus arteriosus during the fourth week of embryonic development. It gives rise to the aortic arches, which are a series of six paired embryonic vascular structures that give rise to several major arteries. These include the brachiocephalic artery, the left common carotid artery, and the left subclavian artery.
Function[edit | edit source]
The aortic sac serves as the initial segment of the aortic arches, which are responsible for distributing oxygenated blood from the heart to the rest of the body. The aortic sac, therefore, plays a crucial role in the development of the circulatory system.
