Arteries to the Thoracic and Abdominal Walls

Blood reaches the thoracic wall through several vessels. These include branches from the subclavian artery and the thoracic aorta (fig. 15.50).

The subclavian artery contributes to this supply through a branch called the internal thoracic artery.

This vessel originates in the base of the neck and passes downward on the pleura and behind the cartilages of the upper six ribs. It gives off two anterior intercostal arteries to each of the upper six intercostal spaces; these two arteries supply the intercostal muscles, other intercostal tissues, and the mammary glands.

The posterior intercostal arteries arise from the thoracic aorta and enter the intercostal spaces between the third through the eleventh ribs. These arteries give off branches that supply the intercostal muscles, the vertebrae, the spinal cord, and deep muscles of the back.

Branches of the internal thoracic and external iliac arteries provide blood to the anterior abdominal wall. Paired vessels originating from the abdominal aorta, in cluding the phrenic and lumbar arteries, supply blood to structures in the posterior and lateral abdominal wall.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
