👉 The term "introthoracic" is a medical term used to describe the position of the thorax (chest) relative to the abdomen. This position is often described as being in the middle or lower third of the chest, with the left arm and right arm extended into the air at shoulder height. The term can also refer to the position of the heart relative to the thoracic cavity, where it may be positioned in a manner that allows for better circulation and oxygenation of the blood.
