What is the Cardiovascular System? The cardiovascular system refers to the heart, blood vessels and the blood. Blood contains oxygen and other nutrients which your body needs to survive. The body takes these essential nutrients from the blood. At the same time, the body dumps waste products like carbon dioxide, back into the blood, so they can be removed. The main function of the cardiovascular system is therefore to maintain blood flow to all parts of the body, to allow it to survive. Veins deliver used blood from the body back to the heart. Blood in the veins is low in oxygen (as it has been taken out by the body) and high in carbon dioxide (as the body has unloaded it back into the blood). All the veins drain into the superior and inferior vena cava which then drain into the right atrium. The right atrium pumps blood into the right ventricle. Then the right ventricle pumps blood to the pulmonary trunk, through the pulmonary arteries and into the lungs. In the lungs the blood

  An Introduction to the Cardiovascular System The cardiovascular system can be thought of as the transport system of the body. This system has three main components: the heart, the blood vessels and the blood itself. The heart is the system’s pump and the blood vessels are like the delivery routes. Blood can be thought of as a fluid which contains the oxygen and nutrients the body needs and carries the wastes which need to be removed. The following information describes the structure and function of the heart and the cardiovascular system as a whole. Structure and Function of the Heart Function and Location of the Heart The heart’s job is to pump blood around the body. The heart is located in between the two lungs. It lies left of the middle of the chest . Structure of the Heart The heart is a muscle about the size of a fist, and is roughly cone-shaped. It is about 12cm long, 9cm across the broadest point and about 6cm thick. The pericardium is a fi

In this blog you will get the information related to the first aid to be provided in case of cardiac arrest. Cardiopulmonary resuscitation ( CPR )  Is an emergency procedure that combines chest compressions often with i n an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest . It is recommended in those who are unresponsive with no breathing or abnormal breathing. CPR involves artificial ventilation chest compressions for adults between 5cm (2.0in) and 6cm (2.4in) deep and at a rate of at least 100 to 120 per minute. The rescuer may also provide artificial ventilation by either exhaling air into the subject's mouth or nose or using a device that pushes air into the subject's lungs. Current recommendations place emphasis on early and high-quality chest compressions over artificial ventilation; a simplified CPR method involving chest compres
