a. Make a diagram showing the nine abdominopelvic regions, and name each region. Name two organs (or parts of organs) that could be located in each of the named regions. b. Make a similar sketch illustrating how the abdominopelvic cavity may be divided into quadrants, and name each quadrant.

Hi, everybody. Welcome back. Here's our next question. The abdominal pelvic cavity is located on the ventral side of the body separated from the thoracic cavity by the diaphragm. The abdominal pelvic cavity can be subdivided into quadrants. The organs spleen and stomach are located in which of the following quadrants. Choice. A right upper quadrant R U Q B, right, lower quadrant R L QC left, upper quadrant L U Q or D left, lower quadrant L L Q. And let's recall for the purpose of this question that right and left here are from the perspective of the person having the body, not from this perspective of someone looking at a diagram or a model. So the stomach is a large organ and easy to visualize the spleen is smaller. It's kind of tucked behind the stomach if you're looking uh head on at someone. So it's a little easier to if we're trying to recall to remember the location of the stomach. And that would be in choice c the left, upper quadrant when we think about our other quadrants and kind of the general layout there. Choice. A the right upper quadrant, the largest and most uh obvious organ there is the liver. So not what we're looking for. My stomach is on the left side. Choice B and D, the right, lower and left, lower quadrants. Of course, we think of as mainly containing the intestines as the most obvious um visibly in terms of organs in those areas, but not where the stomach is. So we cross them out. So the stomach and the spleen both in choice. See the left upper quadrant of the abdominal pelvic cavity. See you in the next video.
