Cardiovascular System

What is Cardiovascular System mean?

The Cardiovascular system consists of the heart and blood vessels. Its primary function is to transport nutrients and oxygen through the blood to all organs of the body and exchange carbon dioxide (Co2) from the blood, Cardio means heart vascular is Blood vessels so its mean Cardiovascular is heart and blood vessels.

What is Function of the Cardiovascular System?

Its have many functions such as Transport nutrients and oxygen in the blood to all parts of the body.

• Carry deoxygenated blood back to the lungs.

• Protect against disease and infection.

• Maintain body temperature.

Organs of The Cardiovascular System

What are the Blood Vessels?

The 3 main types of blood vessels are: arteries — these carry blood pumped away from the heart; they are the largest and strongest blood vessels. veins — these return Co2 from blood to the lung. capillaries — these are tiny vessels that connect arteries and veins.

What are the Heart parts?

The Jobs of these Organs

What is the job of the Pulmonary Arteries?

Your pulmonary arteries carry oxygen-poor blood from your heart to your lungs. This is a vital function. Your blood needs to reach your lungs to gain oxygen and get rid of waste products like carbon dioxide. This blood then returns to your heart, and your heart pumps it out to the rest of your body.

What is the job of Aorta?

The aorta is very essential because it is the main artery that supplies the body with oxygenated blood. Every tissue and organ in the body needs oxygenated blood to survive. As a result, any problem with the aorta - such as a blockage or rupture - can put the rest of the body and all organs at risk.

What is the job of the Tricuspid Valve, Pulmonary Valve, Aortic Valve and Mitral Valve

The heart has four heart valves – the aortic, mitral, pulmonary and tricuspid valves. All four valves open and close to help move blood from one area to another. Two of the valves, the mitral and the tricuspid valves, move blood from the upper chambers of the heart (the atria) to the lower chambers of the heart (the ventricles).

What is the job of Coronary Arteries?

Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart.

What is the job of Superior vena cava?

The superior vena cava is a vital structure in the human circulatory system that helps drain large amounts of deoxygenated blood from the head, eyes, and neck.

What is the job of pulmonary veins?

The four pulmonary veins play an important role in the pulmonary circulation by receiving oxygenated blood from the lungs and delivering it to the left atrium, where it can then enter the left ventricle to be circulated throughout the body.

What is the job of inferior vena cava?

The inferior vena cava is a large vein that carries blood from the torso and lower body to the right side of the heart. From there the blood is pumped to the lungs to get oxygen before going to the left side of the heart to be pumped back out to the body.

What is the job of Conduction system?

Your heart's conduction system is the network of signals that keeps your heart beating. These electrical signals make your heart contract or relax contraction is called systole and relaxing is called diastole. Each contraction also controls blood flow through your heart.
