Question

Which muscle acts as second heart in the lower limb?

Answer 1

Since they act as a pumping system, the calf muscles (gastrocnemius) are called the 'second' or the 'peripheral' heart. The muscles of the calf play an important role in circulation. Contractions of these muscles help in the venous return frm the lower limb.
