Quizplus · Accepted Answer

The respiratory system works to bring in oxygen and remove carbon dioxide from the body through breathing, while the cardiovascular system circulates these gases to and from the cells of the body. The urinary system helps to eliminate waste products from the body, and the digestive system works to break down and absorb nutrients from food, but they do not play as direct of a role in gas exchange as the cardiovascular system does. The endocrine system is responsible for hormonal regulation in the body, but does not directly contribute to gas exchange.
