by Katrina Cain. Tweet. Your appendix is located in your lower right abdomen, attached to the large intestine. Just past the ileocecal valve; the gateway between the small and large intestine, is the cecum; a bulbous mass located at the bottom of the ascending colon.artially digested food and foreign antigens can become stuck in the appendix because of its remote location. Your appendix is a closed tube, making it difficult for your body to clear away debris, should any infection causing bacteria or other matter become stuck.
