Verified step by step guidance

Begin by identifying the location of the muscles involved in the respiratory system. The intercostal muscles are located between the ribs, which is a key anatomical feature.

Understand the function of the intercostal muscles. These muscles play a crucial role in the mechanics of breathing by helping expand and contract the rib cage during inhalation and exhalation.

Differentiate between the types of intercostal muscles. There are external intercostal muscles, which aid in inhalation, and internal intercostal muscles, which assist in forced exhalation.

Consider the anatomical position of the diaphragm, serratus anterior, and pectoralis major. The diaphragm is located below the lungs and is the primary muscle for breathing, while the serratus anterior and pectoralis major are located on the chest but not between the ribs.

Conclude that the intercostal muscles are the correct answer as they are specifically located between the ribs and are directly involved in the respiratory process.
