Study Notes
Blood Pressure and Regulation
- Blood pressure is the force of blood pushing against the walls of arteries.
- Baroreceptors are specialized sensors that detect changes in blood pressure and help regulate it.
- Baroreceptors are located in the walls of certain arteries, such as the carotid artery and aortic arch.
- The function of baroreceptors in the autonomic nervous system is to detect changes in blood pressure and send signals to the brain to regulate it.
- Pressorreflexes are reflexes that help increase blood pressure in response to low blood pressure.
- The role of pressorreflexes in regulating blood pressure is to help maintain a stable blood pressure by increasing it when necessary.
- Systole is the phase of the cardiac cycle when the heart muscle contracts and pumps blood out of the heart.
- Diastole is the phase of the cardiac cycle when the heart muscle relaxes and fills with blood.
- Baroreceptors respond to changes in blood pressure, specifically the stretch of the arterial walls.
