Question

42 both the respiratory system and the digestive system involve the uptake of necessary molecules from an animals surroundings. alveoli are tiny sacs that aid in the exchange of carbon dioxide and oxygen in the lungs. intestinal villi are tiny projections along the lining of the intestines used to take in nutrients from food passing through. which system must interact with the respiratory and digestive systems to transport gases and nutrients throughout the body? a endocrine system b circulatory system c integumentary system d immune system

Explanation:

The respiratory system takes in oxygen and releases carbon - dioxide in the lungs via alveoli. The digestive system breaks down food and absorbs nutrients in the intestines via intestinal villi. To transport these gases and nutrients throughout the body, the circulatory system is needed. It carries oxygen - rich blood from the lungs and nutrients from the intestines to all parts of the body.

Answer:

c. Circulatory system
