1. Cardiovascular, Digestive, Respiratory and Excretory systems are all integrated in their functions in order to maintain homeostasis. What is the common component that must be considered in the function of the digestive, respiratory and excretory systems ?
2. In the body's systems above, there is usually a transport component and a component where the main purpose of the organ system takes place. For example, blood has to be transported via veins and arteries, but exchange takes place in the capillaries. Name as many other examples as you can think of within these systems.
3. How does each system work? What are the general mechanisms (for example, enzymatic action, mechanical action, diffusion, active/passive transport, osmosis, receptor-mediated actions, etc.)?
