Which of the following systems is responsible for transporting nutrients and oxygen to cells in the body?

• Digestive System

• Respiratory System

• Circulatory System

• Nervous System

Explain how the respiratory and circulatory systems work together to support cellular function.

• The respiratory system provides oxygen to the blood, and the circulatory system transports it to cells.

• The circulatory system provides oxygen to the blood, and the respiratory system transports it to cells.

• The respiratory system removes waste from cells, and the circulatory system transports nutrients to cells.

• The circulatory system removes waste from cells, and the respiratory system transports nutrients to cells.

Which of the following is an example of an organ in the human body?

• Blood

• Muscle

• Nerve

Identify the system that includes the brain and spinal cord.

• Circulatory System

• Digestive System

• Nervous System

• Respiratory System

Describe how the digestive system and the circulatory system interact to provide nutrients to the body.

• The digestive system breaks down food into nutrients, which are absorbed into the blood by the circulatory system and transported to cells.

• The circulatory system breaks down food into nutrients, which are absorbed into the blood by the digestive system and transported to cells.

• The digestive system transports nutrients to cells, and the circulatory system breaks down food.
