Explanation:

1. The diaphragm is the muscle that separates the thoracic cavity from the abdominal cavity. It is a dome - shaped muscle crucial for respiration.
2. The term for all the organs in the abdominal and pelvic cavities is viscera. These organs are involved in digestion, excretion, and reproduction among other functions.
3. Bilateral symmetry is typical of all vertebrates. This means the body can be divided into two mirror - image halves along a single plane.

For labeling Figure 1 - 2 and filling the table, without seeing the actual figures, the cranial cavity contains the brain, the vertebral cavity contains the spinal cord, the thoracic cavity contains the heart and lungs, the abdominal cavity contains organs like the stomach, liver, and intestines, and the pelvic cavity contains organs such as the bladder and reproductive organs in males and females.

Answer:

1. Diaphragm
2. Viscera
3. Bilateral symmetry

For table:
Cranial: Brain
Vertebral: Spinal cord
Thoracic: Heart, Lungs
Abdominal: Stomach, Liver, Intestines
Pelvic: Bladder, Reproductive organs
