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