what is the largst muscle in the muscular system
the heart
When a muscle contracts, it performs work. It does this byA)converting chemical energy to mechanical energy.B)converting mechanical energy into heat energy.C)converting mass into energy.D)creating energy.
Since three factors affect muscular strength simultaneously and muscles never work individually, it is misleading to compare strength in individual muscles, and state that one is the "strongest".1) physiological strength (muscle size, cross sectional area, available crossbridging, responses to training)2) neurological strength (how strong or weak is the signal that tells the muscle to contract)3)mechanical strength (muscle's force angle on the lever, moment arm length, joint capabilities)These are few of the strongest muscles-In lifting weights the jaw muscle is the strongest-The tongue is also considered as one of the strongest muscle, this could be true, but it is hard to say as the tongue is made up of 6 muscles-The heart has a claim to being the muscle that performs the largest quantity of physical work in the course of a lifetime.

Work is a scalar quantity.
Assuming that you are doing a whole-body strength routine, you should work your lower body first. The rule is this: work larger muscle groups before small muscle groups. Since your largest muscle groups are lower body groups such as quads and glutes, you should work your lower body before working your upper body. .

Work done is the amount of energy transferred by a force acting through a distance. It is a scalar quantity.
Work is a scalar.
The quantity of work refers to the amount of work that needs to be completed or has been completed within a specific time frame. It can be measured in terms of tasks, projects, hours worked, or output produced. Tracking and managing the quantity of work is essential for productivity and project management.
