Answer 2

Duodenum

Question 3

Four Parts of the Duodenum:

Answer 3

Superior Duodenum
Descending Duodenum
Transverse Duodenum
Ascending Duodenum

Question 4

– is the first part of the duodenum that extends up and to the (R) including the duodenal cap or bulb.

Answer 4

Superior Duodenum

Question 5

Answer 5

Descending Duodenum

Question 6

– passes to the (L) across the midline.

Answer 6

Transverse Duodenum

Question 7

– passes up behind the stomach to join with the Jejunum.

Answer 7

Ascending Duodenum

Question 8

is about 8ft in lenght an extend from duodenum to ileum

Answer 8

jejunum

Question 9

is the part of the small intestine about 15ft in length the extends from jejunum to the junction of colon at the ileo-cecal junction

Answer 9

Ileum

Question 10

The Ileo-Cecal junction has a sphincter called the

Answer 10

Ileocecal sphincter

Question 11

is about 1.5 meters (5 feet) long and extends from the lleo-cecal junction to the anus. It forms an inverted “U” shaped structure that passes up from the (R) lower abdomen to the (R) upper abdomen. It descend to the (L) lateral abdomen to the pelvis.

Answer 11

Large intestine or colon

Question 12

– is that part of the colon that forms a pouch below the ileo-cecal junction. Its lower end is rounded and closed except an opening to the appendix where it is attached

Answer 12

Cecum

Question 13

varies in length from 2-6 inches in length. It usually lies below the cecum but may also lie behind, medial or lateral to the cecum.
The lumen or the cavity of the appendix is a continuation with the cecum that is why, feces or fecal material from the cecum may pass in and back out of the appendix.

Answer 13

Vermiform Appendix

Question 14

– passes up from the Cecum to the under surface of the liver anterior to the (R) kidney.

Answer 14

Ascending Colon

Question 15

– is a bend of the colon to the (L) under the (R) liver surface.

Answer 15

Hepatic Flexure/(R) Colic

Question 16

– passes across the upper abdomen from the hepatic flexure to the spleen in the (L) upper abdomen.

Answer 16

Transverse Colon

Question 17

– is a bend of the colon where the transverse colon ends.

Answer 17

Splenic Flexure / (L) Colic

Question 18

– extends down from the splenic flexure to the brim of the pelvis in the (L) lateral abdomen

Answer 18

Descending Colon

Question 19

• is the “S” shaped curved part of the distal colon extending from the descending colon to the rectum.

Answer 19

Sigmoid/Pelvic Colon

Question 20

– is the final part of the colon that extend from the sigmoid to the anus.

Answer 20

Rectum

Question 21

– is the lower 1 ½ inch of the rectum and ends at an opening— the “anus.”

Answer 21

Anal Canal

Question 22

composed of skeletal muscle

Answer 22

voluntary external anal sphincter

Question 23

composed of smooth muscle.

Answer 23

involuntary internal anal sphincter

Question 24

large intestine, the longitudinal muscle layer of the muscularis externa is reduced to three longitudinal muscle bands called the

Answer 24

tenia coli

Question 25

– are the puckered folds of the colon caused by the arrangement of the longitudinal muscle called the “Tenia Coli”. They are sacculations in the wall of the colon produced by the adaptation of its length to the Tenia Coli.

Answer 25

HAUSTRA

Question 26

major function of the large intestine

Answer 26

is to consolidate and propel the unusable fecal matter towards the anus and eliminate it from the body.
