Transporting oxygen to cells

Producing red blood cells

Previous problemNext problem

Verified step by step guidance

Identify the main functions of the digestive system, which include breaking down food into nutrients, absorbing these nutrients into the bloodstream, and eliminating waste products.

Understand that regulating body temperature is primarily a function of the integumentary system and the hypothalamus in the brain, not the digestive system.

Recognize that transporting oxygen to cells is a function of the circulatory and respiratory systems, involving the heart, blood vessels, and lungs.

Acknowledge that producing red blood cells is a function of the bone marrow, which is part of the skeletal system, not the digestive system.

Conclude that the primary function of the digestive system from the given options is breaking down food into nutrients, as this is directly related to its role in processing and absorbing food.
