Question

Which is the second heart of the human body?

Answer 1

Calf Muscle:

1. The soleus muscle is the second heart of the human body.
2. Our calf veins function as a reservoir for blood that our body does not need to circulate at the moment.
3. The veins that function as reservoirs are known as muscle venous sinuses.
4. As the calf muscle contracts, blood is pushed out of veins and transferred down the venous system.
5. One-way valves in leg veins keep blood flowing in the appropriate direction toward the heart.
6. These valves also keep blood from flowing back down the veins in your legs due to gravity.
