What is the pulmonary circuit? Systemic circuit?

• The pulmonary circuit carries deoxygenated blood between the heart and lungs, while the systemic circuit carries oxygenated blood between the heart and the rest of the body.

• The pulmonary circuit carries oxygenated blood between the heart and the rest of the body, while the systemic circuit carries deoxygenated blood between the heart and lungs.

• The pulmonary circuit carries oxygenated blood to the body, while the systemic circuit carries deoxygenated blood to the lungs.

• The pulmonary circuit and systemic circuit both carry oxygenated blood between the heart and the rest of the body.

What are baroreceptors and what do they do?

• Baroreceptors are sensors located in the blood vessels that help regulate blood pressure by detecting changes in blood pressure and sending signals to the central nervous system.

• Baroreceptors are cells in the liver that help in the digestion of fats by producing bile.

• Baroreceptors are enzymes in the stomach that aid in the breakdown of proteins.

• Baroreceptors are hormones released by the adrenal glands to increase heart rate.
