100% correct, have a lovely day!
To answer question 1, "Which of these body systems performs the function of getting rid of chemical wastes?" you need to understand the functions of each body system. The immune system is responsible for defending the body against diseases, the skeletal system provides structural support, and the nervous system controls body functions. The correct answer is the urinary system as it is responsible for eliminating waste products, including chemical wastes, from the body through urine production and excretion.
To answer question 2, "Which two systems work with the muscular system to allow the body to move?" you need to consider the systems that cooperate with the muscular system. The digestive system is responsible for processing and extracting nutrients from food, while the urinary system is responsible for eliminating waste products. The integumentary system protects the body and regulates temperature, and the endocrine system regulates body functions through hormones. The immune and lymphatic systems protect the body against diseases. The correct answer is the skeletal and nervous systems, as the skeletal system provides the framework for muscle attachment, while the nervous system controls muscle contraction and movement.
To answer question 3, "Which of the following body systems works with the circulatory system to exchange oxygen and carbon dioxide?" you need to understand the function of each body system. The digestive system breaks down and absorbs nutrients from food, the nervous system controls body functions, and the urinary system eliminates waste products. The correct answer is the respiratory system, as it is responsible for the exchange of oxygen and carbon dioxide in the lungs, which is necessary for the circulatory system to transport oxygen to cells and remove carbon dioxide.
To answer question 4, "Which of the following phrases describes the function of the integumentary system?" you need to understand the role of the integumentary system. The integumentary system consists of the skin, hair, and nails, and its main function is to protect the body from external factors such as pathogens and environmental damage. It also helps regulate body temperature and prevents water loss. Therefore, the correct answer is "protective barrier."
By understanding the functions of each body system and their relationships, you can successfully answer these questions related to human body organization.
