The Body and Normal Aging, Part II Selec t from the following set of readings for this unit. The human body depends on the constant flow of air and blood to carry the nutrients vital to survival.
Air flows into the body whereupon oxygen is removed and transferred into the blood.
Oxygen and other nutrients flow through the body to a purposeful destination. The byproducts of metabolism such as carbon dioxide and waste then travel to their destination for removal. The lungs, heart, blood and its vessels, and the spleen are the organs facilitating the intake, storage, and transportation of the products. All processes require a constant movement or flow through the body to effectively reach every cell of the body. The upper respiratory system is responsible for the warming and filtering of inspired air.
