c) middle-aged woman experiencing menopause due to loss of estrogen stimulation
Explanation:
Cellular atrophy is based on the quantitative reduction of structural components and cellular functions, resulting in decreased cell volume in the affected organs or tissues. It consists in the reduction of cell size resulting from the loss of proteins and other cellular materials (as well as organelles), the reduction of cells is also reflected in the reduction of the affected tissue or organ. Usually occurs when the body is already aging. An example of this is a middle aged woman with menopause due to loss of estrogen stimulation.
Answer:
The atria and ventricles are separated by the mitral and bicuspid valves.
Explanation:
The atria undergo atrial systole, a brief contraction of the atria that ejects blood from the atria through the valves and into the ventricles.
Sickle cell anemia is cause when normal, healthy red blood cells morph into an oblong crescent moon shape. Because of the abnormal shape, the red blood cell die quicker resulting in a reduced red blood cell count. White blood cells are elevated because they are constantly trying to get rid of the unhealthy red blood cells. Hemoglobin is an oxygen-carrying protein that is mostly found in red blood cells, and with reduced RBC's, hemoglobin is also reduced.
