The circulatory system is responsible for transporting oxygen and nutrients through an animal's body. To arrive at this answer, you can break down the options provided and evaluate each one:
1. The respiratory system primarily deals with the exchange of gases, such as oxygen and carbon dioxide, between an organism and its environment. While it is involved in obtaining oxygen, it is not responsible for the overall transportation of oxygen and nutrients throughout the body.
2. The digestive system is focused on the breakdown and absorption of nutrients from food. It plays a crucial role in obtaining nutrients, but it does not actively transport them throughout the body.
3. The central nervous system consists of the brain and spinal cord. Its main functions include processing information, coordinating responses, and controlling body functions. Though vital for overall bodily functions, it is not responsible for the transportation of oxygen and nutrients.
4. The circulatory system, also known as the cardiovascular system, is composed of the heart, blood vessels, and blood. It is specifically designed to transport oxygen, nutrients, hormones, and other substances throughout the body. Therefore, the circulatory system is the internal system responsible for transporting oxygen and nutrients in animals.
By considering the functions of each system and eliminating the ones that do not fit the description, you can deduce that the circulatory system is the correct answer.
