Cecum, Appendix, Colon (Ascending, Transverse, Descending, and Sigmoid), Rectum, and Anal Canal
52
What is the muscle that goes around the Colon?
Teniea Coli- Longitudinal Muscle. When its shortened it creates the pockets called Haustra

Important for segmental mixing to get last remnants of nutrients and water of almost fecal matter.
54
Colitis
Inflammation of the haustra
55
Region where the LI turns are called
Right/Left Colic/HepaticFlexures. Right Colic Flexure is lower than splenic flexure because the liver is bigger than the spleen.
56
Cecum is found in what region
Right groin/Inguinal Region
57
If there is an issue with Ascending part of a patient, what region will the physician most likely to see
Right Flank/Lumbar region
58
If there is an issue with Transverse part of a patient, what region will the physician most likely to see
All top 3 regions consist of Right Hypochondrium, Epigastric, and Left Hypochondrium
59
A patient with pain in Descending portion of his colon will have what portion of the Abdominal cavity looked at
Left Flank/Lumbar Area
60
Sigmoid is in what region
Left Inguinal/Groin and also Pubic/hypogastric area
61
LI is part of almost all the regions except
Umbilical Region
62
Where is Cecum found
Its the First part of the LI. It sits in the Right Iliac fossa
63
Cecum gets its blood supply from
Anterior and Posterior Cecal Arteries which branches off of Illiocolic artery that comes directly from SMA
64
Where does Appendix originates
Where Tenaie coli begins in the cecum. Contains aggregation of Lymphoid tissue
65
