Term
examples of heart problems
Definition
hypertension- high blood pressure (can lead to heart attacks)
Term
examples of digestive problems
Definition
colitis (colon inflammation) and gastric ulcers
Term
examples of how ANS can reduce resistance to disease
Definition
glucocorticoids- hormones released by the adrenal glands during stressful times depressed the activity of the immune system

Term
symptoms of neuroblastoma
Definition
increased heart rate, sweating, and high blood pressure (known for spontaneous remission)
