A patient with severe allergies experiences systemic vasodilation and increased capillary permeability, leading to a dangerous drop in blood pressure. To maintain homeostasis, the body's compensatory mechanisms would primarily involve:

  1. Positive feedback to further dilate vessels and deliver more blood to tissues.
  2. Negative feedback via sympathetic activation to increase heart rate.
  3. Parasympathetic stimulation to slow the heart and conserve energy.
  4. The release of insulin to stabilize the metabolic rate of the vascular smooth muscle.
