This is in order to increase the surface area available to the blood that carries the red blood cells in it, in order to maximize the amount of oxygen and carbon dioxide transfer that is needed to keep you alive.
The digestive system is made up of many structures. Humans need different structures to process the varieties of foods we eat on a daily basis.
You need a respiratory system to bring oxygen into your body and to remove carbon dioxide from your body..
so that they can breath. If you do not know the respiratory system is used for breathing
Many simple organisms, such as single-celled organisms like bacteria and protozoa, do not require specialized respiratory systems because they can exchange gases directly through their cell membranes. Additionally, small aquatic animals like jellyfish and flatworms also rely on diffusion for gas exchange, as their thin body structures allow oxygen and carbon dioxide to pass through easily. These organisms thrive in their environments without the need for complex respiratory structures.
This system is called the respiratory system. It exchanges oxygen that the cells need to make energy for carbon dioxide which is a waste product that the cells make.
Actually, earthworms have no respiratory system at all, they get the oxygen and nitrogen that they need from the soil.
The respiratory system consists of living tissue that requires food to survive. The digestive system processes the food you eat and turns it into a form that can be carried to the cells of the respiratory system so they can be well nourished and keep the respiratory system functioning properly..
