The Baroreceptor Reflex and the Diving Reflex - 547 Words

The baroreceptor reflex and the diving reflex are both two great mechanisms that incorporate both the nervous system and cardiovascular system working together. The nervous system is connected through a series of vessels throughout the human body. The circulatory system is one of the bodies most important mechanisms that helps carry and transport nutrients and oxygen through blood circulation to help digest foods, fight off diseases, and keep the body at homeostasis. The nervous system is basically an extended system of the brain. Every action that the brain thinks, relays it through the nervous system to the specific body part to perform that action. Nerves send information from and to the brain to help regulate and operate organs and muscles in the body. Now how these two systems operate together can be described and explained through information about the baroreceptor reflex and diving reflex. The baroreceptor reflex is a homeostatic mechanism in the body which helps regulate a st able blood pressure. The way that the baroreceptor reflex works is that it provides a negative feedback loop so that when blood pressure increases, the reflex causes the heart rate to decrease in return decreasing blood pressure. When there is increased blood pressure, the carotid arteries and aorta stretches causing the baroreceptor reflex to increase it’s action potential generation. These action potentials are sent to the medulla oblongata through nerves in the body, and as a result,Show MoreRelatedChanges Of The Cardiac System1932 Words   |  8 Pagessystolic pressure is added to two thirds of the diastolic pressure. This gives us an accurate measurement of how much cardiac output by total peripheral resistance there is at one point and time. The mean arterial pressure is then monitored by baroreceptors that act to control blood volume, heart rate, stroke volume, and blood flow due to diameter of arterioles and veins (Sherwood, 374-380). The cardiac systems have many differing measurements to ensure proper function and response to situations
