Final answer:
The trunk contains several areas of the body, including the abdomen, chest or thoracic cavity, and back. It houses organs and systems like the central nervous system, digestive and respiratory systems, and is supported by core muscles that maintain posture. (options a, b & c are the correct answers).
Step-by-step explanation:
The trunk of the human body includes several key areas. These are the abdomen, the chest (also known as the thoracic cavity), and the back. Within these regions, different components of the human body are contained and served by various systems.
For example, the dorsal cavity includes both the head and the back of the trunk, housing the brain and spinal cord which are part of the central nervous system.
The ventral cavity, located at the front of the trunk, is divided into the thoracic cavity, containing the lungs and heart, and the abdominopelvic cavity, encompassing organs like the stomach, intestines, and reproductive organs.
The deep muscles of the trunk, such as those in the vertebral column, thorax, and abdominal wall, play an important role in maintaining posture and balance.
