Take a look at the following case studies that detail an outcome associated with a disease/organ malfunction. Select one study to investigate further for your assignment.

Critically evaluate the information provided and correlate it with the organ systems that are affected in the scenario. Use the information that you have gathered to answer the assignment questions that follow the case study. For assistance with your assignment, please use your text, the AIU Library, Web resources, and course materials.

On June 22, 2002 the St. Louis Cardinals were preparing for their upcoming baseball game against the Chicago cubs.

Answer the following assignment questions:

Describe the functions of both arteries and veins. Vertebrates and some invertebrates have a closed circulatory system. Explain the advantage of having a closed circulatory system over an open circulatory system? Briefly explain how the lymphatic system is associated with the circulatory system?
