The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out. When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward.
How is respiration different from breathing?
Breathing and respiration are two completely different but interrelated body processes which assist body organs to function properly. Breathing is the physical process of exchanging gases whilst respiration is a chemical process which takes place at a cellular level and produces energy.
What is alveolar ventilation equal to?
Although alveolar ventilation is usually defined as the volume of fresh air entering the alveoli per minute, a similar volume of alveolar air leaving the body per minute is implicit in this definition.
What is the difference between respiratory and circulatory systems?
Unlike the respiratory system, circulatory system is a network of blood. Circulatory system pumps blood around the body and the Respiratory system is to take oxygen in and expel carbon dioxide. Both systems involve oxygen for the body to work. I hope this was helpful!

What is alveolar sac?
(al-VEE-oh-ly) Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
What is the most important body system in the human body?
While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The human nervous system is responsible for coordinating every movement and action your body makes.
