Case Study a&P1
Case Studies
1. A small family was traveling in its van and had a minor accident. The children in the back seats were wearing lap belts, but still sustained numerous bruises about the abdomen, and had some internal organ injuries. Why is this area more vulnerable to damage than others? Name specific organs that would be injured, as well as the abdominopelvic quadrant and region in which they are found. What injuries might you suspect in the damaged organs?
The area is vulnerable because all of the visceral organs in the peritoneal cavity are not protected by the rib cage. The rib cage only protects the pleural half, which contains the heart, lungs. The kidneys, stomach, liver and other peritoneal visceral organs are unprotected by apparatus. The reason for this is that unlike the heart and lungs, the digestive track, particularly the stomach, can expand and moves considerably a lot more than the heart and lungs. In order for peristalsis to occur, the muscles in these visceral organs contract and relax. If there were a rib cage around it, it would restrict movement of visceral organs. A&P 9th ed. Pg. 17
2. The client was admitted to the hospital with hypertension. The development of arteriosclerosis has increased peripheral resistance to blood flow, worsening his hypertension. This is an example of what type of feedback loop and why? Once you have identified the type of feedback loop present in this case study, please discuss how it differs with the opposite feedback loop.
This is a Positive feedback as referred as “cumulative causation”, a situation where some effect causes more of itself. A system undergoing positive feedback is unstable; it will spiral out of control as the effect amplifies itself. Negative feedback is a way for counteracting an effect and it control body temperature thermoregulation. A&P 9th ed. Pg. 12
3. Mr. Martinez read that cholesterol was bad for his health, so he eliminated all foods and food products
