Pick one system we have studied this year. Describe how that system changes over a lifetime. Cite three specific changes that occur. This can be, but is not limited to diseases that become more likely with age. Number your changes.
Solution
Sure, I'll choose the cardiovascular system for this question.
-
Arterial Stiffening: As we age, our arteries, which are the large blood vessels that carry blood from the heart to the rest of the body, can become stiff. This is due to the walls of the arteries thickening and the space inside the arteries narrowing. This condition is known as arteriosclerosis. It can lead to high blood pressure and other cardiovascular problems.
-
Heart Muscle Changes: Over time, the heart muscle can become thicker and less efficient at pumping blood. This can lead to a decrease in the amount of blood that the heart can pump with each beat, which can cause symptoms such as fatigue and shortness of breath.
-
Increased Risk of Heart Disease: With age, the risk of developing heart disease increases. This is due to a variety of factors, including the two mentioned above, as well as lifestyle factors such as diet and exercise habits. Other conditions, such as diabetes and high cholesterol, can also increase the risk
