Reconstruction of the ACL (anterior cruciate ligament) and repair of a torn meniscus are among the most commonly performed arthroscopic surgeries. Within the knee, these structures perform distinct functions. The ACL helps stabilize and support the joint. There are two menisci in the knee.
â¢ LIQUID (noun) The noun LIQUID has 4 senses: 1. a substance that is liquid at room temperature and pressure. 2. the state in which a substance exhibits a characteristic readiness to flow with little or no tendency to disperse and relatively high incompressibility. 3. a substance in the fluid state of matter having no fixed shape but a fixed volume.
Liquid is just one of the several states of matter. Along with solids and gas, liquid is the middle phase with regard to the phases of water change (from ice, to melted ice, and then to water vapor). A solid ice cube becomes water because of melting. Melted water turns to water vapor because of evaporation.
