Things to Know About The Cardiovascular System

Published on July 3, 2022

The cardiovascular system is the blood circulation system of the human body. Itincludes the lungs, the heart and a system of blood vessels. That carry oxygen to organs and muscles and take away waste products.

The cardiovascular system is responsible:

For transporting oxygen around the body once it has taken in via the respiratory system. This is done by pumping blood around the body through veins and arteries. Other key features of the cardiovascular system are the heart and lungs. The heart’s main job is to pump blood around the body and the lungs are responsible for oxygenating (giving oxygen to) the blood.

Blood carries oxygen around the body and is made up of several parts, including plasma and white and r blood cells. R blood cells carry oxygen to the working muscles. The process is continuous, starting at the lungs where r blood cells are oxygenat by haemoglobin being given oxygen from the capillaries after oxygen is taken from the lungs.

Once the blood has oxygenat:

The cardiovascular system then takes the blood to the heart. It first travels through the chambers and into the ventricles where it is then pump out through the arteries. The arteries pump blood to all of the muscles in the body and also to vital organs such as the liver and brain, which also ne a supply of blood. Working muscles require the most blood and the harder a group of muscles work, the more blood that is transport to that area of the body. This means that more oxygen can be given to the muscles where it can then be convert into energy that the body nes.

Cardiovascular oxygen has given to the muscles:

Via the process of osmosis (i.e. where oxygen molecules move from an area of high concentration. To an area of low concentration so the high concentration of oxygen. In the blood spreads into the muscles) the blood then passes into the veins. The next stage of the cardiovascular system. The veins take the deoxygenated blood back to the heart where they pass into the side opposite. Where it leaves through the artery, once more through a chamber, down into the ventricle. The heart then pumps the blood out and back towards the lungs. Where the red blood cells can stock up on oxygen again.

The heart made up of cardiac muscles.

As these are involuntary, we cannot choose how fast our heart pumps. It responds directly to how hard the body works. Sensors all over the body sense how hard the body is working at any given moment and send signals to the heart if the blood needs to pumped around the body faster.

In order to do this, we must understand the vascular system. The body is composed of some fifteen trillion cells, which grouped according to tissues, and cells and further categorized into various systems. The organ, cell, and the organ system have their own designated purpose.

In high blood pressure, the organs involved are the heart, skin, kidneys, lungs. Some glands while the systems involved are the excretory and the cardiovascular systems. Further, the muscle and vascular tissues also included.

The individual cell requires oxygen and plenty of nutrients.

When nutrients metabolize, there is buildup of waste products, especially carbon dioxide being the abundant, to removed. This is where the cardiovascular system will enter into the picture removing. The wastes and distributing the nutrients to every cell.

The heart will pump a bright red blood filled with oxygen to the aorta. The biggest artery, and to the arterioles and capillaries. The arteriole is the small blood vessel that extends. And branches from the artery, which connected to the capillaries (smallest blood vessels).

The arterioles and microscopic Cardiovascular:

Which have oxygen and other nutrients, will penetrate every tissue for distribution to each cell. The venous system returns the purified blood to the heart during circulation. By carrying the waste-laden blood to the lungs for carbon dioxide removal. And to the kidneys for removal of wastes. As an important function of the cardiovascular system, blood is cleansed and will returned. To the heart for another circulation, this time for distribution.

The peripheral circulatory system is the system when the arterioles. And veins transport the blood to and from the muscles and skin. The purpose of which is to bring nutrients and remove wastes in the cells, and regulate body temperature. The body temperature regulated an increase in the blood flow to emit heat. And the blood flow reduced when conserving energy.
