Which of the following best describes the main function of the circulatory system?

• to deliver nutrients and other essential materials to cells and remove waste products
• to break down the nutrients found in food so that they can be used by all cells in the body
• to produce the chemical signals that allow parts of the body to communicate with other parts
• to coordinate all other body systems so that they can function together to maintain homeostasis and carry out life processes

Muscle cells in athletes often have more mitochondria than muscle cells in non-athletes. Based on this observations, it can be inferred that the muscle cells in athletes

• have a smaller demand for cell proteins than the muscle cells of non-athletes
• have nuclei containing more DNA than nuclei in the muscle cells of non-athletes
• reproduce less frequently than the muscle cells of non-athletes
• have a greater demand for energy than the muscle cells of non-athletes

The human skeletal system is an example of how function depends on structure. Which statement describes the relationship between the structure and function of the human skeletal system?

• The skeletal system breaks down food into nutrients that the body can use.
• The skeletal system returns fluids to blood vessels and helps get rid of bacteria and viruses.
• The skeletal system provides a frame to support and protect the body and allows the body to move.
• The skeletal system receives information about the body and the environment and responds to that information.

Which of the following best explains an interaction between the digestive system and the respiratory system?

• To use the energy in food broken down by the digestive system, the body needs oxygen obtained by the respiratory system.
• The main function of the respiratory system is to control, coordinate, and regulate most of the functions of the digestive system.
• Coordination between the respiratory and digestive systems is necessary because the digestive system obtains oxygen needed by the respiratory system.
• The digestive system obtains nutrients from the food that is eaten, and the respiratory system transports the nutrients to the brain

Sam had a disease that weakened his heart so it could not pump properly. This caused him to have low energy because his cells couldn’t get the nutrients they needed. Based on this information, Sam’s disease primarily affected the functions of which two systems?

• skeletal system and digestive system
• muscular system and cardiovascular system
• integumentary system and muscular system
• excretory system and cardiovascular system
