The function of the cardiovascular system is to make sure your body gets the oxygen, nutrients and other things it needs and gets rid of things it doesn’t.
Why is the cardiovascular system important?
Your heart and blood vessels, the parts of the cardiovascular system, are important because they bring oxygen, nutrients and other good things to every cell in your body. They also take away carbon dioxide and waste. This supply of nutrients and the removal of waste is the main function of the cardiovascular system.
What system supplies the body with oxygen and nutrients?
The cardiovascular system (your heart and blood vessels) supplies your body’s organs with oxygen and nutrients so your organs can do their jobs. Your blood vessels also carry carbon dioxide and other waste away for disposal.
Why is it so hard to deliver oxygen to the cardiovascular system?
Many of the problems with the components of the cardiovascular system have to do with slowdowns or blockages in the blood vessels. Since your blood vessels supply your entire body with oxygen, a blockage in any of the blood vessels makes it harder to deliver that oxygen.
What is the role of the heart in the circulatory system?
Your heart uses the far-reaching, intricate network of blood vessels to deliver oxygen and other necessary things to your whole body. This network also removes the things your body doesn’t need and takes them to organs that can get rid of the waste. Your blood carries the oxygen, nutrients and waste through your entire body.

How does the heart work?
The heart makes blood circulation by acting as a pump, and the blood carries oxygen and nutrients to all tissues of the rest of the body. If the heart stops working for a few minutes, the blood will not be circulated throughout the body, and the whole body will stop working, and the whole life will fall in danger. The heart has two sides, as left and right sides, and four chambers.

What is the heart's pericardium?
The heart is suspended in its own membranous sac, the pericardium. The strong outer portion of the sac, or fibrous pericardium, is firmly attached to the diaphragm below, the mediastinal pleura on the side, and the sternum in front. It gradually blends with the coverings of the superior vena cava and the pulmonary (lung) arteries and veins leading to and from the heart. (The space between the lungs, the mediastinum, is bordered by the mediastinal pleura, a continuation of the membrane lining the chest. The superior vena cava is the principal channel for venous blood from the chest, arms, neck, and head.)
How are the heart and ventricles divided?
The heart is divided by septa, or partitions, into right and left halves, and each half is subdivided into two chambers. The upper chambers, the atria, are separated by a partition known as the interatrial septum; the lower chambers, the ventricles, are separated by the interventricular septum. The atria receive blood from various parts of the body and pass it into the ventricles. The ventricles, in turn, pump blood to the lungs and to the remainder of the body.

The apex of the heart is formed by the tip of the left ventricle and lies just above the diaphragm at the level of the fifth intercostal space to the left.
Where is the heart located during cardiopulmonary resuscitation?
It is level with the second rib below the sternum. Posteriorly, the heart rests on the bodies of the fifth to the eighth thoracic vertebrae. Because of its position between the sternum and the spine, rhythmic compression of the heart can maintain blood flow during cardiopulmonary resuscitation.

How does the circulatory system help you?
Your circulatory system plays a critical role in keeping you alive. Blood vessels carry blood to the lungs for oxygen. Then your heart pumps oxygen-rich blood through arteries to the rest of the body. Your veins help your body get rid of waste products. Conditions like high blood pressure, high cholesterol and atherosclerosis can affect the health of your circulatory system. If you have one of these conditions, talk to your healthcare provider about steps you can take to protect your cardiovascular health.

Your heart pumps blood to the body through a network of arteries and veins (blood vessels). Your circulatory system can also be defined as your cardiovascular system. Cardio means heart, and vascular refers to blood vessels.
Which system pumps blood to the lungs?
The circulatory system ( cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.

What is the fluid that carries oxygen and nutrients vital to the function of the body?
Blood. Blood is the fluid that carries the oxygen and nutrients vital to the function of the body, as well as the waste that needs to be removed. Without blood, the human body could not function. Blood flows between the heart and the rest of the body, with red blood cells providing oxygen and white blood cells fighting foreign invaders.
How does blood help the body?
In addition to providing oxygen and nutrients, blood also helps cleanse the body by collecting waste products like carbon dioxide. The continuous, controlled circulation of the blood the cardiovascular system provides is what maintains homeostasis. With oxygen provided and waste removed, the body can perform its normal functions.
How many chambers does the heart have?
In terms of structure, the heart has two sides and is divided into four chambers: the left atrium, the right atrium, the left ventricle, and the right ventricle. The thin-walled atria receive blood from the veins, and the thick-walled ventricles pump blood out of the heart. On the left and right sides of the heart, the atrium and ventricle work together to pump blood through and out of the heart.
