Your final journal of the semester is here. This one is a bit more relaxed.
One of the hopeful and apparent themes throughout the course is how all of the systems are interrelated in one way or another. No one system functions in isolation or independent of any other system.
With that said. Select any system within the body (even from A&P I) and link it to at least 2 other systems. Explain the homeostatic, endocrine, negative feedback (as appropriate) mechanisms that help to link the systems together. Discuss and shared or common organs between these systems, or functions that are shared.
Yes, I am leaving this topic kind of vague so as to allow you maximum freedom in creating your response. No need to cite your responses because this is BASED ON WHAT YOU HAVE LEARNED... this question is not intended for you to research. If you do research portions of your response, then yes! You must cite that information.
Any questions, please let me know!

HUNTINGTON’S DISEASE is an autosomal dominantly inherited, degenerative human disease of the nervous system. Individuals homozygous for this dominant gene almost always die as a fetus. The disease has no obvious phenotypic effects in a heterozygous individual, until a person is about 35-40 years old, well into child-rearing years. There is no known cure for this genetic disease.
E. Determine the results of a mating between two parents, both of whom will get Huntington’s disease.

Sickle cell anemia is inherited as an autosomal, recessive disorder. Individuals who inherit the mutated gene from both parents will show symptoms of sickle cell, including a stiffening of the red blood cells when the individual is under conditions with low oxygen levels in the air (e.g. on top of a mountain). This can lead to low red blood cell count (anemia), shortness of breath, fatigue, jaundice, and joint pain. Most critically, the stiffened red blood cells can clog small blood vessels, blocking blood flow to critical organs (e.g. brain, lungs, liver, etc.) that can lead to death. Curiously, heterozygous carriers have a certain amount of resistance to malaria. The malaria parasite must invade red blood cells in order to develop and apparently the cell surface is altered in heterozygous individuals, thereby limiting the ability of the malaria parasite to enter the red blood cells. Recall that the rules for autosomal recessive diseases are that only the homozygous recessive individuals experience the symptoms of sickle cell anemia.
C. Determine the results of a mating between two parents that are both heterozygous for sickle cell anemia.
