What do the digestive system and circulatory system of the human body have in common?

• They work together to help give the body the ability to speak, smell, and breathe.

• They work together to give cells the nutrients needed to produce energy.

• They work together to reduce waste and keep the body clean.

• They work together to pump blood throughout the body.

How do the digestive and circulatory systems differ in how they help the body obtain nutrients?

• The digestive system breaks down food into red blood cells, and the circulatory system carries these red blood cells throughout the body.

• The digestive system breaks down food into usable nutrients, and the circulatory system carries these nutrients throughout the body.

• The digestive system breaks down food, and the circulatory system moves the food from the stomach to the large intestines.

• The digestive system mixes food with water, and the circulatory system moves the mixture through the intestines.
