Body System Olympic Interactions Checkpoint Station 1: Heart Rate &Breathing Which 3 body systems were working together and affecting your body during the Station 1 breathing activity? Circulatory, Digestive, Respiratory because breathing fast makes my stomach hurt. Circulatory, Muscular, Respiratory because my diaphragm helps me breath and my blood circulates the oxygen through my body. Integumentary, Muscular, Respiratory because my diaphragm helps me breath and that makes my skin sweat.

## Step 1<br />The problem is asking us to identify the three body systems that work together during the breathing activity. The options provided are:<br />- Circulatory, Digestive, Respiratory<br />- Circulatory, Muscular, Respiratory<br />- Integumentary, Muscular, Respiratory<br /><br />## Step 2<br />We need to consider the functions of each system in relation to breathing. The circulatory system is responsible for transporting oxygen and nutrients throughout the body, the digestive system is responsible for breaking down food and absorbing nutrients, and the respiratory system is responsible for the exchange of gases (oxygen and carbon dioxide).<br /><br />## Step 3<br />The circulatory system works in conjunction with the respiratory system to deliver oxygen to the body's cells and remove carbon dioxide. The muscular system, specifically the diaphragm, plays a crucial role in breathing by contracting and relaxing to allow air to enter and exit the lungs.<br /><br />## Step 4<br />The integumentary system, which includes the skin, does not play a direct role in the breathing process. Therefore, the option that includes the integumentary system is not correct.
