1 Hip muscles. Lunges work all of the gluteal muscles in the hips, primarily the gluteus maximus that is used to extend your hips. Taking large steps during a lunge can further engage this muscle. The gluteus minimus and gluteus medius are also used to stabilize your body throughout the lunge.  Thigh muscles.
1 Movement of air into and out of the lungs is called pulmonary ventilation, or breathing (Figure 13.3). 2  When inspiratory muscles contract, intrapulmonary volume increases, its pressure decreases, and air rushes in (inspiration).3  When inspiratory muscles relax, the lungs recoil and air rushes out (expiration). Each plunges into the hilus of the lung on its side. 2  The lungs are paired organs flanking the mediastinum in the thoracic cavity. 3  The lungs are covered with visceral pleura; the thorax wall is lined with parietal pleura. 4  Pleural secretions decrease friction during breathing.
