Ligament & Meniscus. Related topic Background Each knee has two menisci. They are commonly called âthe cartilageâ, although this is not strictly accurate. There is one on the medial (inner) side of the knee and one on the lateral (outer) side of the knee. They are C, or crescent shaped, and serve to cup the femur as it sits on the tibia to improve the congruity of the joint.
expiratory reserve volume. Type:Term. Definitions. 1. the maximal volume of air (about 1000 mL) that can be expelled from the lungs after a normal expiration.
1 Residual volume (RV), about 1,200 mL, is the volume of air still remaining in the lungs after the expiratory reserve volume is exhaled.  The total lung capacity (TLC), about 6,000 mL, is the maximum amount of air that can fill the lungs (TLC = TV + IRV + ERV + RV).
