Final answer:
The appropriate suture for intestinal mucosa closure is Vicryl, an absorbable suture material suitable for the healing process required in the gastrointestinal tract. The greater omentum is the membrane covering the stomach but is not listed in the provided options. Lacteals are associated with villi and aid in the absorption of fats.
Step-by-step explanation:
The suture most appropriate for closure of the intestinal mucosa is Vicryl (option a). Vicryl is an absorbable suture made of polyglactin 910, which is commonly used in gastrointestinal surgery because of its ability to maintain tensile strength for the time needed to heal, yet eventually be absorbed by the body. Using non-absorbable sutures like silk or Prolene could lead to complications as they remain in the body indefinitely, potentially causing irritation or infection. Dexon, while absorbable, is not as commonly used as Vicryl for this purpose.
When discussing the membranes covering the stomach, the correct answer is not the falciform ligament but rather the greater omentum, which is an extension of the peritoneum and protects the abdominal organs. The greater omentum is not listed in the provided options; however, it is the structure that is closely associated with the stomach.
As for which of these is most associated with villi, the correct answer is b. lacteals. Villi are small, finger-like projections that line the small intestine and are key to nutrient absorption. Embedded within these villi are the lacteals, which are part of the lymphatic system and help to absorb fats from the digested food.
