These simple vessels allowed early humans to navigate coastal waters and rivers for fishing and trading purposes.

It means circulatory system
With the exception of walking, cycling is the cheapest means of transport.
Two major means of active membrane transport are primary active transport, which directly uses energy in the form of ATP to transport molecules against their concentration gradient, and secondary active transport, which uses the energy stored in the electrochemical gradient of one molecule to drive the transport of another molecule against its gradient.
Active Transport
