Diaphragm and intercostals
Veins are assisted in maintaining one way flow by the skeletal muscles' contrations. Valves also ensure one-way flow.
Skeletal muscles work in pairs: flexors and extensors
They allow your body to move.

A muscle is either contracting (doing work) or relaxing (not under tension). Some muscles do not ever completely relax under normal conditions.
The muscles that connect to bones are called skeletal muscles. These muscles are attached to bones via tendons and enable voluntary movements of the body. Skeletal muscles work in pairs to facilitate motion, contracting to pull on bones and allowing for a wide range of physical activities.
False. While many skeletal muscles do work in antagonistic pairs (e.g. biceps and triceps), not all skeletal muscles function this way. Some skeletal muscles work alone or in synergy with other muscles to produce movement.
These muscles are called "skeletal muscles".
Your triceps and your biceps. These muscles are part of the skeletal muscle group they move by contracting and relaxing.
When a runner uses her leg muscles to run, she is primarily using skeletal muscles. Skeletal muscles are under voluntary control and are responsible for movement by contracting and relaxing. These muscles work in coordination to provide the strength and agility needed for running. In addition to skeletal muscles, some smooth muscles may be involved in regulating blood flow and digestion during exercise.
