Blood pressure is measured as two numbers, such as 120/80. The first number (120) represents systolic pressure, which is the highest level of blood pressure when your heart beats. The second number (80) represents diastolic pressure, which is the lowest level of blood pressure when your heart rests between beats.
Blood pressure is very important for your health. If your blood pressure is too high or too low, it can damage your heart, brain, and other organs.
Now the question arises why this happens? So when the blood coming out of the heart puts pressure on the walls of the veins, it is called blood pressure. The body has two major systems for controlling blood pressure: one short-term and one long-term.
The short-term system includes baroreceptors and chemoreceptors. The main function of baroreceptors is to control blood pressure, while chemoreceptors help in correcting the balance of chemical elements present in the blood.
On the other hand, in the long run the renin-angiotensin-aldosterone system (RAAS) comes into play, which has the greatest impact on blood pressure. This system plays an important role in keeping blood pressure stable and maintaining the body's water and sodium balance.
Both baroreceptors and chemoreceptors work in different ways. Baroreceptors send signals to the medulla oblongata of our brain, while chemoreceptors keep track of the chemical composition of our blood.
