This course on the digestive system aims to help learners understand the anatomy and functions of the gastrointestinal tract. By the end of the course, students will be able to identify and describe the different digestive organs, layers of the GI tract, and accessory digestive organs. They will also learn about the vascular supply and innervation of the GI tract. The course teaches skills such as recognizing the arterial supply to different parts of the GI tract, understanding the functions of organs like the liver, gallbladder, pancreas, and spleen, and grasping the role of sympathetic and parasympathetic innervation in digestion. The teaching method involves a video tutorial format with a detailed breakdown of each topic. This course is intended for students, medical professionals, or anyone interested in gaining knowledge about the human digestive system.
