Skeletal-muscle pump : ウィキペディア英語版 | Skeletal-muscle pump
The skeletal-muscle pump is a collection of skeletal muscles that aid the heart in the circulation of blood. It is especially important in increasing venous return to the heart, but may also play a role in arterial blood flow. ==General== The skeletal pump is vital in negating orthostatic intolerance when standing. When moving upright the blood volume moves to the peripheral parts of the body. To combat this the muscles involved in standing contract and help to bring venous blood volume to the heart.〔 The pump is important in affecting the central and local supply of blood output. Venous return, cardiac output, and stroke volume were all increased during exercise experiments, as well as affecting the local muscle being used, blood volume.
