The muscle cells are loaded with mitochondria to allow large amounts of ATP production while the macrophages have abundant lysosomes to digest the debris and dead organisms like bacteria. 
Mitochondria are known as the powerhouse of a cell. This is because most of the ATP production used by various systems in their operation is produced by mitochondria. A chemical called NADH is produced in the mitochondrial matrix through the Krebs cycle. The enzymes embedded in the mitochondrial membrane use this chemical to produce Adenosine Triphosphate, generally known as ATP. 
Macrophages are phagocytic white blood cells involved in engulfing and killing pathogens. They are involved in the innate immune response of the body. Lysosomes have specialized enzymes that can kill these pathogens. 
Muscle cells need to contract or expand for which they require energy. Thus, they have abundant mitochondria. Whereas, the macrophages have abundant lysosomes to help them kill disease-causing pathogens like a virus or bacteria.

Explanation:
Answer: The higher animals needs and internal transport system so that the innermost cells can get nutrition which cannot be left on diffusion and osmosis to transmit. They also needed an internal transport system and so that they get oxygen to the internal cell...
