triangular opening that forms exit of inguinal canal, located in anterior wall of abdomen
superficial inguinal ring
36
cord-like structure in males formed by vas deferens and surrounding tissue that run from deep inguinal ring down to each testicle
spermatic cord
37
round ligament leaves pelvis via deep inguinal ring, passes through inguinal canal and continues on to the majora, originates at uterine horns in parametrium
round ligament of uterus
38
blood vessel that carries oxygenated blood and arises from internal thoracic artery. anastomoses with inferior epigastric artery at umbilicis.Supplies anterior part of abdominal wall and some of diaphragm.
superior epigastric artery
39
artery that arises from external iliac artery and anastomoses with superior epigastric artery.
inferior epigastric artery
40
horizontal line that demarcates lower limit of the posterior layer of rectus sheath
arcuate line ***
41
small protrusions of extraperitoneal fand and /or peritoneum and omentum and sometimes bowel. Result from increased intraabdominal pressure in presence of weakness or incomplete closure of anterior abdominal wall after ligation of umbilical cord at birth
umbilic hernias
42
thin aponeurotic membrane which lies between inner surface of transversus abdominis muscle and extraperitoneal fascia

49
ductus (vas) deferens - transport sperm from epididymis to ejaculatory ducts in anticipation of ejaculation
50
what is this organ?
liver - detoxification, protein synthesis, and production of biochemical necessary for digestion
51
gall bladder - bile is stores before it is released to small intestines - can live without.
52
important organ for digestive tract. involved in second phase of digestion following chewing ( mastication)
stomach
53
organ that acts as a blood filter. Located in left upper quadrant of abdomen. Synthesizes antibodies in white pulp and removes antibody coated bacteria and antibody coated blood cells through blood an dlymph node circulation.
spleen
54
lesser omentum
55
greater omentum
56

57
glandular organ in digestive system and endocrine system. Produces hormones such as insulin, glucagon, somastatin
pancreas
58
ave peritoneum on their anterior side only. Structures that are not suspended by mesentery in the abdominal cavity and that lie between the parietal peritoneum and abdominal wall are classified as
retroperitoneal
59

61
right lower quandrant; union of ileum ot cecum
ileocecal junction **
62
cecum - pouch, considered beginning of large intestine - receives chyme from ileym and connects ascending colon of large intestine.
63

64
What are the four sections of the colon?
ascending, transvers, descending, and sigmoid
65
differentiate the different parts of the large intestine

70
fundus - formed by upper curvature of stomach
71
Body - region between fundus and pylorus
72
