Analyse how the cardiovascular and the digestive system interrelate to perform energy metabolism. Energy is used up all the time for body processes. Energy starts at conception and continues to carry on until you die. The amount of energy you need depends upon your age‚ sex and your level of activity. Food provides the energy we use; our foods bring us the vital energy that our body is burning throughout the day. Body growth‚ development and functioning are some of the vital and fundamental aspects

The myocardium (cardiac muscle)‚ is the thickest section of the heart wall and contains cardiomyocytes‚ the contractile cell of the heart. 2. What part of the heart is the pacemaker and why? The SA Node is located in the right atrium of the heart. It is made up of a group of cells (myocytes) positioned on the wall of the right atrium‚ at the center of the heart and near the entrance of the

the lungs for oxygenation (pulmonary circulation). The left cavity composed of the left atria and left ventricle receives the oxygenated blood from the lungs and pumps this blood to all body parts through the aorta (systemic circulation). The heart has four valves that regulate the flow of blood through its chambers. Blood flow from the right atrium to the right ventricle is regulated by the tricuspid valve. The pulmonary valve regulates blood flowing into the pulmonary artery from the right ventricle

veins help bring that blood back to the heart. Arteries carries oxygenated blood away from the heart‚ and veins carry deoxygenated blood back to the heart. This process is called circulation. The roles are revered in pulmonary circulation. The pulmonary arteries bring deoxygenated blood to your lungs‚ while the pulmonary veins will bring
Premium Heart Blood Circulatory system
Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac muscle) is a specialised form of muscle
