The reasons for efficient respiratory and circulatory systems evolved as animals’ energy demands increased. Concept introduction: The major function of the respiratory system is to supply oxygen for cellular respiration and disposal of the carbon dioxide that is a waste product of the cellular respiration. The circulatory system is responsible for bringing oxygen, nutrients, and hormones to the cells of the body.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.
