5 Questions
What is the purpose of a transport system in mammals?
The purpose of a transport system in mammals is to efficiently supply nutrients and rapidly remove wastes.
What are the limitations of diffusion in providing nutrients to cells?
The limitations of diffusion in providing nutrients to cells include a small surface area to volume ratio and longer diffusion distance, which results in slow and insufficient diffusion.
What is the term for the movement of fluid down a pressure gradient?
The term for the movement of fluid down a pressure gradient is mass flow.
Why is a transport system necessary for mammals with high metabolic rates?
A transport system is necessary for mammals with high metabolic rates because diffusion alone would be too slow and insufficient to meet their high energy demands.
What role do blood vessels play in the circulatory system?
Blood vessels carry blood and allow for an efficient supply of nutrients and rapid removal of wastes.
