The respiratory system of birds differs significantly from that found in mammals‚ containing unique anatomical features such as air sacs. The lungs of birds also do not have the capacity to inflate as birds lack

Aging is something that continuously happens throughout life‚ which produces a lot of changes throughout the body. With that being said‚ many changes throughout the body affect the respiratory system. As individuals age‚ bones of the body become thin‚ weak‚ and change shape. The ribcage is affected by this change and can alter a person’s breathing as it becomes unable to expand and contract the way it used to. Muscles in the body also become weak. If the muscle that supports breathing‚ called the

OF THE RESPIRATORY SYSTEM The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. Respiration is achieved through the mouth‚ nose‚ trachea‚ lungs‚ and diaphragm. Oxygen enters the respiratory system through

rib cage moves down and in diaphragm relaxes. The lungs are the main part of the respiratory system. The respiration system produces energy from taking oxygen and produces carbon dioxide which is takes place in the cells. The oxygen goes to the mitochondria inside the cell where it combines with sugar to create energy and produce carbon dioxide and water. The respiratory system connects to circulatory the system because blood goes to the lungs and to picks up oxygen and releases carbon dioxide
