• nervous

• excretory

• cardiovascular

What are the main functions of the human skeleton?

• exchange of gases

• support and movement

• sensing the environment

• digestion and excretion

Instinctive reactions are easily observed in human body functions. When an individual smells food, the body releases certain hormones that trigger salivation and increase appetite. Hearing a sudden, loud noise causes other hormones to circulate through the body, preparing it for a possible threat. Based on this information, it can be concluded that instinctive responses are controlled by the

• reproductive system.

• digestive system.

• circulatory system.

• endocrine system.

Which of the following is NOT a function of the integumentary system?

• to provide the body's defense against infection

• to transport nutrients throughout the body

• to help maintain the body's temperature

• to help sense objects outside the body

What is the main function of the immune system?

• to stimulate the transmission of disease-fighting enzymes

• to recognize and attack disease-causing organisms

• to alert other systems in the body of foreign cells

• to maintain a constant flow of blood to wounds

An animal's skin protects it from extreme temperatures. When an animal senses it is too cold, it curls into a ball. During this process, the skin works in conjunction with which body system?

• the digestive system

• the immune system

• the reproductive system

• the nervous system

The brain signals the body of an animal to move by transmitting electrical impulses through neurons. An animal is then able to walk or run because

• the heart of the circulatory system works with the stomach of the digestive system.

• the muscles of the muscular system work with the bones of the skeletal system.

• the glands of the endocrine system work with the skin of the integumentary system

• the kidneys of the excretory system work with the white blood cells of the immune system.

The respiratory system supplies oxygen to the blood in the body, while removing carbon dioxide. Which system directly interacts with the respiratory system to maintain homeostasis?

• the excretory system when it sends out liquid waste as urea

• the skeletal system when oxygen and glucose around the ribs are absorbed

• the nervous system when the brain regulates the body's breathing and heart rate

• the digestive system when food is broken down for nutrients
