2. Ligamentum arteriosum:
The aortic arch loops over the left pulmonary artery and the bifurcation of the pulmonary trunk,
to which it remains connected by the ligamentum arteriosum, a remnant of the fetal circulation
that is obliterated a few days after birth.
3. Caecum:
The cecum is a pouch-like dead-end passage that branches inferiorly from the end of the ileum
(end part of small intestine). Fecal matter entering the large intestine from the ileum passes into
the cecum before being pushed superiorly into the ascending colon. The appendix is attached to
the inferior end of the cecum and is believed to store beneficial bacteria that help break down
undigested food.
