When we engage in running or exercise, our cardiovascular and respiratory systems respond to the increased demand for oxygen and nutrients by our muscles. The nervous system plays a role in facilitating these responses, with the sympathetic nervous system activating and increasing our heart rate. Our respiratory system also responds by increasing our breathing rate, allowing for more oxygen intake. The respiratory and cardiovascular systems work together to ensure that the oxygen is efficiently taken up by our muscles during running. Next, we'll learn about the lymphatic and integumentary systems from Griffin. Thanks, Sabrina. Now I'm going to connect both systems to running. When you engage in running or any form of physical exercise, your body's cardiovascular and respiratory systems respond to meet the increased demand for oxygen and nutrients by the working muscles. The involvement of the nervous system plays a crucial role in facilitating these responses during running with cardiac conduction. As you start running, the demand for oxygen and nutrients in your muscles rises. The sympathetic nervous system is activated, leading to an increase in heart rate. The SA node in the right atrium acts as the pacemaker, generating electrical impulses at a faster rate, which translates to a higher heart rate. When you start running, the respiratory system also responds by increasing the rate and depth of breathing. This elevated respiratory rate also allows for a higher intake of oxygen. The respiratory and cardiovascular system work together to optimize oxygen intake. As the heart rate increases due to cardiac conduction system, the respiratory rate also elevates to meet the heightened oxygen demand. This ensures that the oxygen transported by the blood is efficiently taken up by the working muscles during running. Now we'll go to Griffin to learn about the lymphatic and integumentary systems.
