The Different Organs Of The Cardiovascular System

Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work

The hearts function as a double pump that serves two circulations. The pulmonary pump in the right side of heart is provided for the gas exchange in the body, and the systemic circulation in the left side provides the functional blood supply to all body tissues. The functional blood to the heart is provided by the coronary arteries. Right coronary artery supplies the heart through the posterior interventricular and marginal artery branches; and the left coronary artery supplies the heart via anterior interventricular artery and the circumflex artery. The myocardium is drained by great, small, and middle cardiac veins which

Our cardiovascular system is composed of the heart and blood vessels. The main purpose of this system is to transport substances throughout the body. Even though transportation is the main function of the cardiovascular system, it is not the only function. Along with transportation we have protection and regulation.

Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.

The heart pumps the blood around the body through the blood vessels which is made of mostly veins and capillaries. The blood carries the dissolved oxygen around the bodily

A heart attack occurs when an artery that supplies blood to the heart becomes blocked. The loss of oxygen and nutrients damage the heart's muscle tissue, causing the remaining healthy tissue to pump even harder to keep up.

Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns

Oxygen and nutrients the body requires for function are pumped around this complex network of blood vessels by the heart. At roughly the size of a human fist, the heart is a four-chambered muscle and performs two functions of circulation simultaneously and continuously. Systemic and pulmonary circulation. The heart is made up from three separate layers of cardiac tissue; the outer layer called the pericardium, which is a double sac-like outer covering with serous fluid inside to keep the middle layer, the myocardium from adhering to the outer layer. This middle layer of the heart is the heart muscle which is thicker on the left side, to aid with the pressure needed to sustain systemic circulation. The inner layer of the heart is the endocardium. It’s lining is smooth to help prevent the blood which circulates around the inside of the heart from clotting. The heart is the human body’s in-built pacemaker, and the electrical signals sent through the it cause the heart to contract and relax. This process is triggered by the autonomic nervous system and the contraction and relaxing cycle is

The right atrium is where the process begins. Then, blood travels through the tricuspid valve to the right ventricle, and from there to the pulmonary artery. Once the blood travels through the pulmonary artery, it reaches the lungs. While in the lungs, the blood goes through a gas exchange: deoxygenated blood gets oxygenated (The gas exchange takes place in the alveoli, which are tiny air sacs in the bottom of the lungs

Tim Taylor, 2012) has argued that cardiovascular system referred to as the circulatory system, is composed of blood within the blood vessels and heart. The function of the heart is pumping the blood through the blood vessels of the body.

On the right side of your heart, it is collecting and pumping blood to the lungs through the pulmonary arteries, in which your lungs are refreshing the blood with a new supply of oxygen, and removing any waste products (Heart Disease- Mayo Clinic). On the left side of your heart, it pumps more blood throughout the aorta ( the main artery), to supply tissues throughout the body with oxygen and nutrients( Heart Disease- Mayo Clinic).

The second body framework is the cardiovascular system which contains the blood, heart, and vessels. The cardiovascular system heart pumps blood through veins, blood conveys oxygen and supplements to cells and carbon dioxide and waste far from cells. It manages body temperatures and water substance of body fluids and blood. This system contains of the heart, veins, and arteries. The heart is somewhat little and lays on the diaphragm which rests on the mediastinum and is located in the thoracic cavity. The mediastinum reaches out from the sternum to the vertebral column. From the first rib to the diaphragm and sits between the lungs. The heart has an apex which is the pointed end of a cone shaped structure, and a base which is the posterior

The heart is located beneath the rib cage, between the lungs, to the left of the sternum (breastbone). Most people believe that the heart is located on the left side of the chest because the bottom of the heart is tipped to the left. Therefore, you feel more of your heart on the left side. The heart is a powerhouse with muscular walls that contract, thrusting blood throughout the body’s blood vessels. The blood must flow in one direction in order for the heart to function properly. The three focal types of vessels are arteries, capillaries, and veins which form the circulatory system. These vessels, like elastic tubes, transport blood to every portion of the body. Arteries carry oxygen-rich blood away from the heart to all of the body’s tissues. They progressively become smaller as blood is carried further away from the heart. The capillaries are the small, thin blood vessels that connect the arteries to the veins. Nutrients, carbon dioxide and waste products are allowed to pass to and from the tissue cells by their thin walls. Veins, on the other hand, carry the oxygen-poor blood back to the heart. These vessels gradually become larger as they get near to the heart. The blood vessel system runs over 60,000 miles long.

The cardiovascular systems function is to pass blood through ones body keeping their muscles oxygenated, to keep nutrients that are needed in the body and to help get rid of metabolic waste. The cardiovascular system is made up of three components, these are; the heart, the blood and the blood vessels.
