Final answer:
Rosa's body systems, specifically the circulatory and respiratory systems, work together to transport nutrients and oxygen to cells while removing wastes like carbon dioxide, thereby maintaining homeostasis.
Step-by-step explanation:
Rosa's body systems work together to break down food into smaller molecules that are then delivered to the body's cells via the bloodstream. This process ensures that nutrients and oxygen are supplied to the cells while removing waste products such as carbon dioxide. The circulatory system and respiratory system play pivotal roles in this process. The digestive system breaks down food into nutrients, which enter the bloodstream and are transported to cells by the circulatory system. The respiratory system ensures that oxygen is taken into the lungs, diffuses into the blood, and is then carried to cells for aerobic cellular respiration. This combined effort of organ systems maintains the body's homeostasis.
