The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Biological systems are made up of group of organs that perform a particular function.

Biological systems are peculiar to higher organisms. Examples include:

  • Digestive system: this system consists of organs that brings about the assimilation and digestion of food. It carries out this function through the mouth, stomach, small intestine and large intestine.
  • irculatory system: this system serves the basic function of transporting soluble food, excretory products and oxygen, throughout the body. This system consists of the heart, arteries, veins and so on.

The division of labour in the body systems leads to efficiency of their various functions.

But the two biological systems mentioned above are interconnected. Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System which then carries those nutrients where they need to go.
