Sarah was playing soccer on a hot day when she accidentally tripped and scraped her knee. After a while, she noticed that her knee had changed in appearance and became painful. Her coach, who has some basic knowledge of the human body, explained that this change was due to the body's natural response to an injury. Which of the following best describes the role of the lymphatic system in this situation? The lymphatic system transports oxygen to the injured area to aid in recovery. The lymphatic system carries red blood cells to the injury site to promote healing. The lymphatic system transports the pain signal from the injury site to the brain to start the recovery process.
