Our Body Systems

The Respiratory System

Walt: We are learning about our body systems and how they work.

The Respiratory System (also called the Ventilatory System) is a biological system which has specific organs and structures. They are used for the process of respiration in a organism. The Respiratory System is involved in the intake and exchange or oxygen and carbon dioxide between an organism and the world. Respiration takes place in the respiratory organs called the lungs.
  • The passage of the air into the lungs to supply the whole body is known as inhalation and the one going out is known as exhalation.
  • The Trachea leads to the lungs through the windpipe
  • The windpipe splits into two different pipes
  • The first one is called the Bronchus and leads into the chest with many different pipes going off the main one
  • The air comes through our nose, through the windpipe to the lungs, then the carbon dioxide comes back up on the other side of the windpipe and out of the mouth

Circulatory System

The Circulatory system, (also called the cardiovascular system) is an organ system which helps to transport blood, gases (such as amino acids), oxygen and nutrients around the body. It helps to nourish the body, but also helps to fight off diseases in the body, keep body temperature as well. It is often composed as both the cardiovascular system (which distributes blood) and the lymphatic system (which circulators the lymph). The heart is made up of four chambers. There are two chambers on each side. The two chambers at the top are called atria, meanwhile the chambers on the bottom are called the ventricles.
