Describe the Physiology of the Cardiovascular System in Relation to Energy.
Describe the physiology of the cardiovascular system in relation to energy.
A.T.P is stored, chemical energy in the cell, without A.T.P we would die. To make A.T.P we need glucose oxygen. Carbon dioxide and heat are the waste products.
The main function of the cardiovascular system in relation to energy is to transport the oxygen and glucose to the cells, and to transport the waste products such as carbon dioxide and urea (waste product from protein digestion) away from the cells and to the lungs or kidneys.
Blood is a liquid connective tissue as it is made up of living cells (red and white). Oxygen is transported in red blood cells, attached to a protein called haemoglobin while nutrients, including glucose, are dissolved in the plasma (the liquid content of the blood). The red blood cells also carry iron; Iron is a mineral that is found in every cell in the body. It’s an important part of red blood cells, which carry oxygen as iron will attract the oxygen and without the significant amount the body would not function properly. Our cells use oxygen to make energy. Iron also is needed to keep the immune system healthy and help brain cells work normally.
There are four main organs organ’s in the cardiovascular system.
Heart:

The main organ of the cardiovascular system is the heart this is a fist sized organ located in the central chest cavity. The heart is a strong, powerful organ, consisting of cardiac muscle. The heart pumps continuously, without resting and without becoming tired. Its function is to pump blood to the lungs and around the body.
The heart consists of four chambers and is divided into left and right by a wall of muscle called the septum. The right side of the heart consists of an atrium which receives blood returning from the body, and the right ventricle, which then pumps blood out to the lungs, via the pulmonary artery.
The left side again contains an atrium and a ventricle. The left atrium receives the oxygenated blood returning

    The heart is what some determine to be the most important organ in our bodies and one of the biggest contributors. It is one of the major organs that if we did not have, it would not be possible for us to live. The heart is about the size of a fist and is broken down into four chambers, the aorta, superior vena cava, pulmonary artery, and the coronary artery. The four chambers include the right and left atrium and the right and left ventricle. The heart is responsible for supplying oxygen and blood to the entire body. Blood passes through these four chambers and then exits and pumps into the rest of the body. The heart also has three layers of walls…

    The myocardium, commonly referred to as the heart, acts as a pump for transporting blood around the body via a collective system, known as the cardiovascular system. This system has various components; blood vessels; mainly arteries, veins and capillaries. The cardiovascular system has four main functions within the body. Firstly to transport dissolved oxygen, hormones, nutrients, salts, enzymes and urea to cells located around various places within the body, whilst at the same time eliminating any waste products such as carbon dioxide and water. Secondly, to protect the body from infection and blood loss. Thirdly, to distribute heat around the body to enable a healthy temperature of 37oc and finally to aid the body to maintain fluid balance. This ‘human pump’ can be regarded as two pumps. The fist sized organ contains two muscular chambers; the upper chamber; the atrium and the lower; the ventricle. The right side of the heart pumps deoxygenated blood from the veins to the lungs for oxygenation, whilst the left side pumps oxygenated blood from the lungs to the body. It is important to note that the two sides are separated by a septum. The blood flows through the heart twice within one cycle, this is known as ‘double circulation’.…

    The heart consists of four hollow chambers two atria that receive blood from the body’s veins. And two ventricles that pump blood into the body’s arteries. There is a thin wall between the atria’s that is called the interatrial septum. There is a wall between the ventricles called interventricular septum.…

    Moving right along, we now can see the right atria. The right atria is part of the heart, which is the upper chamber, which receives the de-oxygenated blood form our body from the vena cava and is then pumped into the right ventricle of the heart, which is the lower chamber of the heart. After it has done so it will move its way to the lungs under low pressure, which is via the pulmonary artery and there the blood will be turned into oxygenated blood. Between the right atria and the right ventricle…

    The function of the heart is to pump blood throughout the body. The heart pumps blood containing oxygen from the lungs to body. It passes blood without oxygen back to the lungs for more oxygen. The heart has four chambers; the two upper chambers are called atriums, and the two lower chambers are called ventricles. The left atrium is located above the left ventricle, and they are separate by a valve called the mitral valve. The…

    1. The left atrium gets blood from the lungs then passes it into the left ventricle. The heart pumps oxygenated blood out through the large aorta and carries blood to the rest of the body. 2. The blood drains back to the heart then goes into the right atrium and the right ventricle pumps blood to the lungs.…

    The heart lies in the thoratic cavity, organs associated with the heart are inferiorly, the hearts apex rested on the tendon of the diaphragm, superiorly, the great blood vessels, posteriorly the oesophagus, trachea and the left and right bronchus, laterally, the lungs and anteriorly the sternum and ribs. (Waugh& Grant 2014). The heart provides a constant blood circulation action and the blood vessels provide a network for the blood flow. The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body, ( www.le.ac.uk) the right side of the heart pumps blood to the lungs (pulmonary circulation) and the left side receives oxygenated blood and supplies it to the rest of the body (systemic circulation). There are three types of blood vessel, arteries, capilleries and veins. Blood is pumped from the heart through the arteries at high pressure which could damage the tissue so it needs to go through the capillaires which are smaller low pressure blood vessels that are responsilbe for providing oxygen to the tissues, they also absord excess carbon dioxide and then deliver the blood into the veins which then supply the blood back to the heart. The heart generates its own electrical impulses, it does not rely on any other external mechanisn to make it beat. A normal heart rate is 60-80 times per minute, factors which can decrease or…
