Why are the lungs, the major organ of the respiratory system, also considered an excretory organ?

• They get rid of carbon dioxide, a cellular waste

• They get rid of oxygen, a cellular waste

• They get rid of urea, a cellular waste

• They get rid of salt, a cellular waste

In humans, the gases oxygen and carbon dioxide must be exchanged between the environment and cells. During this exchange, oxygen is delivered to the red blood cells so that they can function properly in the blood stream. Which two body systems are working together to achieve this goal?

• Endocrine and Reproductive

• Skeletal and Muscular

• Respiratory and Circulatory

• Digestive and Excretory

When your body comes in contact with a sharp object, an impulse sent you your brain triggers a reflex that causes you to move away from the object. What body systems are interacting to cause this response?

• Nervous, Respiratory,

• Nervous, Muscular

• Nervous, Skeletal

• Nervous, Digestive

An infectious disorder that produces lesions on the brain in lab animals is caused by parasites. When gonads (testes or ovaries) are removed from the lab animals, the resistance to the infection increases and fewer lesions are produced. The two systems working together are

• digestive and circulatory

• immune and endocrine

• reproductive and muscular

• skeletal and endocrine

Pathogens are disease causing agents such as bacteria, virus, or fungi. What systems work together to protect the body from these would be invaders?

• endocrine and reproductive

• circulatory and immune

• digestive and skeletal

• lymphatic and respiratory

The systems that regulate the process of birth in mammals would include

• endocrine (hormones), muscular (contractions), and reproductive (gestation)

• endocrine (hormones) and muscular (contractions)

• endocrine (hormones) and reproductive (gestation)

• endocrine (hormones), reproductive (gestation) circulatory (blood to organs)
