2. Torso

The torso is the central core of the body, divided into three primary regions: anterior (front), posterior (back), and lateral (sides).

A. Anterior (Front) Torso

Thorax (Chest): Houses the heart and lungs; includes ribs, sternum, and the upper part of the spine.
Abdomen: The central and upper abdominal region containing organs such as the stomach, liver, intestines, and pancreas.

Posterior (Back) Torso:

Lumbar Region: The lower back area with five robust vertebrae at the base of the spine.
Thoracic Spine & Vertebral Column: Supports the ribcage and upper back.
Gluteal Region: Though part of the pelvis, the buttocks are often grouped with the lower back.

B. Pelvic Region

Located at the inferior end of the torso, the pelvis supports the organs of the lower gastrointestinal and reproductive systems, and bears much of the body’s weight.
