Explanation:

Question 6

The thoracic cavity is the chest cavity that houses the lungs, heart, and other thoracic organs. The mediastinum is the central compartment of the thoracic cavity (not where the lungs are located), the abdominal cavity holds digestive organs, and the cranial cavity holds the brain. So the lungs are in the thoracic cavity.

The biological organizational levels from lower to higher are: organelle, cell, tissue, organ, organ system. So an organ is higher than tissue (tissues group to form organs), while system is higher than organ, cell is lower than tissue, and organelle is lower than cell.

The coronal (or frontal) plane divides the body into anterior (front) and posterior (back) portions. Sagittal planes divide into left/right, median is a type of sagittal (midline), and transverse divides into superior/inferior.

Answer:

A. thoracic cavity.
