When a person’s body needs water, the brain
helps maintain homeostasis by sending
signals that make the person

Atherosclerosis is a condition
in which
blood pressure is consistently higher than normal.
muscles in artery walls lose their ability to contact.
capillaries widen and release too much fluid.
artery walls thicken as the result of a buildup of fatty
materials.
Right ON! Atherosclerosis
can lead to heart attacks.
