Final answer:
The ventral cavity, at the front of the trunk, contains the majority of vital organs such as the heart, lungs, and liver, necessary for survival and proper body function.
Step-by-step explanation:
The portion of the body that contains most of the vital organs is known as the ventral cavity. This cavity houses organs that are critical to the body's operations, including the heart, lungs, stomach, intestines, and reproductive organs. The human body contains five organs that are considered vital for survival: the heart, brain, kidneys, liver, and lungs.
The ventral cavity is at the anterior, or front, of the trunk, and it allows for considerable organ support and protection, particularly for the liver which is the largest gland and functions in metabolism and regulation.
