The carotid body senses changes in what?

Blood Pressure
Carbon Dioxide
Oxygen
Blood Sugar

The correct answer is: Oxygen

The carotid body is a small cluster of chemoreceptors located near the bifurcation of the carotid arteries in the neck. It plays a crucial role in sensing the levels of oxygen in the blood. When the oxygen level decreases, the carotid body sends signals to the brain to increase the rate and depth of breathing, helping to ensure that the body receives an adequate supply of oxygen. In contrast, options A, B, and D are not specifically sensed by the carotid body. Blood pressure is sensed by baroreceptors, carbon dioxide levels are primarily sensed by the central chemoreceptors in the brain, and blood sugar levels are monitored by various organs including the pancreas.
