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 from...
