A patient stands up quickly after lying down for several hours and briefly experiences dizziness. Which physiological mechanism is primarily responsible for restoring arterial blood pressure within seconds?

Chemoreceptors in peripheral tissues detect reduced oxygen levels and directly increase stroke volume

Stretch receptors in the carotid sinus decrease their firing rate, leading to increased sympathetic output

Osmoreceptors in the hypothalamus stimulate water retention to immediately increase blood volume

Coronary artery receptors activate parasympathetic pathways that constrict systemic arteries
