A. The primary function of the musculoskeletal system is to provide support, posture, and heat production.

B. The primary function of the gastrointestinal system is to break down food into small molecules that can be absorbed by the cells of the body.

C. The primary functions of the integumentary system are to help regulate body temperature, aid in the synthesis of vitamin D, and provide sensory input.

Which of the following body systems contains cardiac, skeletal, and smooth tissues?

A. Lymphatic

B. Integumentary

C. Muscular

D. Endocrine

C. CORRECT. Cardiac tissue, skeletal tissue, and smooth tissue are all parts of the muscular system.

A. The lymphatic system is a series of vessels. It does not contain cardiac, skeletal, or smooth tissues.

B. The integumentary system is comprised of skin and accessory structures. It does not contain cardiac, skeletal, or smooth tissues.

D. The endocrine system is comprised of glands that secrete hormones. It does not

contain cardiac, skeletal, or smooth tissues.

Which of the following body systems works with the respiratory system to transport waste products from the body's cells?

A. Peripheral nervous

B. Endocrine

C. Cardiovascular

D. Reproductive

C. CORRECT. The cardiovascular system works with the respiratory system to remove waste from the body's cells.

A. The peripheral nervous system consists of spinal nerves that transmit information to and from the brain, but it does not aid in cellular elimination.

B. The endocrine system regulates metabolic activity, but it does not aid in cellular elimination.

D. The reproductive system produces hormones and facilitates reproduction, but it does not aid in cellular elimination.

Which of the following organ structures within the digestive system is primarily responsible for the absorption of nutrients?

A. Stomach

B. Small intestine

C. Bile duct

D. Esophagus

B. CORRECT. The small intestine is primarily responsible for the absorption of nutrients, which is the final process of digestion.

A. The patient's height is measured in meters, inches, or feet and is not a factor to consider when maintaining homeostasis.

B. The patient's weight determines the patient's mass in kilograms or pounds and is not a factor to consider when maintaining homeostasis.

C. The patient's oxygenation status is assessed by performing a pulse oximetry and is not a factor to consider when maintaining homeostasis.

When pain signals are received by the brain, which of the following body systems is alerted to initiate a movement response?

A. Muscular

B. Cardiovascular

C. Digestive

D. Integumentary

A. CORRECT. The muscular system receives signals from the nervous system in response to pain, which causes the muscles to contract or move.

B. The cardiovascular system does not control movement responses and would not be alerted.

C. The digestive system does not control movement responses and would not be alerted.

A. Cardiovascular

B. Respiratory

C. Muscular

D. Digestive

D. CORRECT. The digestive system experiences a decrease in peristalsis during a fight-or-flight response. The movement of food is slowed down as it passes through the digestive system, preventing vomiting or defecation as a response to fear or trauma. The system will remain in this state until the individual feels safe.

A. The cardiovascular system experiences an increase in heart rate during a fight-or-flight response.

B. The respiratory system experiences a widening of the bronchioles to increase the flow of oxygen during a fight-or-flight response.
