This time we are talking about the nervous system in correlation with the cardiovascular system! The cardiovascular system refers to the heart, veins and arteries. As you know, our heart is what keeps us alive! Our heart has four valves and four chambers that pump our blood out to our arteries so they can deliver the oxygenated blood to our muscles and organs. Then our veins return the deoxygenated blood to our heart so it can send it through our lungs to be oxygenated once again before the whole process is repeated. And this is happening all the time! It’s so crazy how our body regulates this on its own.
Speaking of regulation, it is actually the nervous system that regulates our heart rate and blood pressure. Blood pressure ensures the correct distribution of blood to the body. Baroreceptors are what ensures that this is accomplished. Baroreceptors are pressure sensors that detect the arterial pressure through negative feedback loops. The most important baroreceptor is the carotid sinus. If the blood pressure suddenly jumps and the arterial walls expand then the frequency of the sending of the action potential is increased. This leads to blood pressure falling back to normal and the frequency firing of the receptors to fall as well.
Overall, I really enjoyed learning about the cardiovascular system because this was honestly a system I didn’t know much about! I’m glad that I learned to identify the different veins and arteries as well as the basic functions of the heart because it is just good basic knowledge. I would recommend that everyone know about the basics of heart because it is something that affects all of us.
