Question

What muscles are involved for horses to breathe in and out?

Answer 1

The main muscles involved in a horse's ability to breathe in and out include the diaphragm, intercostal muscles, and the muscles of the abdomen. The diaphragm, which is a dome-shaped muscle located at the base of the ribcage, contracts to create a negative pressure in the chest cavity, allowing air to be drawn into the lungs during inhalation. The intercostal muscles, located between the ribs, help expand and contract the ribcage to facilitate breathing. The muscles of the abdomen assist in exhalation by pushing the diaphragm upwards to help expel air from the lungs.
