Although orthostatic hypotension has many causes, in the elderlyit can be due to age-related decreases in neural and cardiovascular responses. Decreased fluid intake while feeling ill and sweating due to a fever can result in dehydration. Dehydration candecrease blood volume and lower blood pressure, increasing thelikelihood of orthostatic hypotension.a. Describe the normal response to a decrease in blood pressureon standing.b. What happened to Molly’s heart rate just before she fainted?Why did Molly faint?c. How did Molly’s fainting and falling to the floor help establishhomeostasis (assuming she was not injured)?

Hematology

Hematology is the branch of biology. Hematology is the medical field that deals with the treatment of blood disorders and cancers, such as hemophilia, leukemia, lymphoma, and sickle-cell anemia. Hematologists and hematopathologists are medical professionals who specialize in illnesses of the blood and its components.
