A function of a thick-walled empty cell in a leaf vein could be to provide structural support and rigidity to the vein, helping it withstand mechanical stress and maintain its shape. Additionally, these cells may play a role in facilitating the transport of water and nutrients through the leaf vein by creating a channel for fluid flow. The thick walls of these cells can also help regulate the flow of substances by acting as a barrier or filter.
its all about blood flow blod
it carries blood throughout your entire body
Veins carry blood to the heart but never away from the heart. They do the opposite job of an artery.
because of it's shape the skeletal muscle can contract much easier.
