Enrichment Questions
Instructions: This is an honors level course. Answer all questions fully using complete sentences. If you want full credit, please provide plenty of details. 1. How is the concept of homeostasis related to aging and disease? Provide examples to support your thinking.
-The lack of homeostasis (called homeostatic imbalance) can cause several different types of diseases and disorders. Homeostasis will make sure of the efficiency in control functions of the body. Diabetes, gout, and any disease caused by a toxin in the bloodstream result from homeostatic imbalance. 2. When we are dehydrated, we are thirsty and drink water. Is this part of negative or positive feedback control systems? Explain your reasoning.
-Positive, as the body has a response to lack of water by signaling to the brain the urge for a drink, 'thirst', which needs quenched and will wake you from a deep sleep, being thirsty is quite an urgent which will distract the person until they quench it and then when enough fluids have been taken, the body switches off the “thirst mode.” 3. Why would you have a hard time understanding physiology if you did not also understand anatomy?
-Because one would not know that the two terms are virtually the same in some ways they use the same processes. Both anatomy and physiology have their differences but one cannot understand anatomy without knowing physiology and vice versa. 4. Describe the different body cavities. -dorsal body cavity -cranial cavity, enclosed by the skull and contains the brain, eyes, and ears. -spinal canal, enclosed by the spine and contains the spinal cord. -ventral body cavity -thoracic cavity, enclosed by the ribcage and contains the lungs and heart. -abdominopelvic cavity -abdominal cavity, enclosed by the ribcage and pelvis and contains the kidneys, ureters, stomach, intestines, liver, gallbladder, and pancreas -pelvic cavity, enclosed by the pelvis and
