use the information below to answer questions 2 and 3
human organs
tooth
heart
lungs
skeleton

1. draw a line to match each function with the correct organ.

pump blood around the body
tooth
give shape and aids in movement
heart
chews and breaks down food
lungs
breathe in oxygen and exhale carbon dioxide
skeleton

Explanation:

To solve this problem, we match each function to the correct human organ based on their known roles:

1. pump blood around the body: The heart's main function is to pump blood throughout the circulatory system. So, match with "heart".
2. give shape and aids in movement: The skeleton (bones) provides structural support, shape to the body, and enables movement (along with muscles). So, match with "skeleton".
3. receive and interpret messages: The brain is the control center of the nervous system, responsible for receiving, processing, and interpreting sensory information and sending out responses. Wait, but in the given organs (brain, heart, lungs, skeleton) – wait, the user’s list has "brain", "heart", "lungs", "skeleton". Wait, the function "receive and interpret messages" is for the brain. But let's check the options again. Wait, maybe a typo? Wait, the original problem’s organs: "brain", "heart", "lungs", "skeleton". Let's re-express:

• pump blood around the body → heart (heart circulates blood).
• give shape and aids in movement → skeleton (bones provide structure and enable movement).
• receive and interpret messages → brain (brain processes neural signals).
• breathe in oxygen and exhale carbon dioxide → lungs (lungs are the site of gas exchange: O₂ in, CO₂ out).

So the correct connections are:

• pump blood around the body → heart
• give shape and aids in movement → skeleton
• receive and interpret messages → brain
• breathe in oxygen and exhale carbon dioxide → lungs

To answer the question (drawing lines to match), the pairs are:

• pump blood around the body — heart
• give shape and aids in movement — skeleton
• receive and interpret messages — brain
• breathe in oxygen and exhale carbon dioxide — lungs
