How are villi, nephrons, and alveoli similar in their functions?

• all three are vital for intake of nutrients into the body

• all structures are responsible for gas exchange within the body

• all three increase surface area for the absorption of materials in the body

• all play a role in providing protection for cells of the body

Which best explains a result of the body systems working together?

How does your skin help the body maintain homeostasis?

• When you’re hot, your skin excretes sweat to “cool” the body down.

• When you’re cold, you shiver to produce heat through muscle contractions just under your skin.

Which explains the relationship between the digestive system and circulatory system?

• The circulatory system assists the digestive system in breaking down food for the body.

• The digestive system digests products of the circulatory system.

• The circulatory system carries products from the digestive system to various parts of the body.

Which best describes the common functions between the respiratory, excretory, and digestive systems?

• all three are vital for intake of nutrients to the body

• all play a role in removing waste or unused products from the body

• all three work together to provide energy for the body

• all work with the circulatory system to move blood through the body
