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

and _conductivity___. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the __sodium-potassium pump______. This system moves _sodium____ out of the cell and ___potassium___ into the cell. The inside of the cell membrane is negative‚ not only due to the active transport system but also because of _intracellular proteins_‚ which remain negative due to intracellular pH and keep the inside of the cell membrane negative

Fluid balance is when the quantity of water we gain each day is equivalent to the amount we lose to the environment. The upkeep of normal fluid balance includes regulating the content and sharing of body water in the ECF and the ICF. The digestive system is the main source of water gains; a small amount of extra water is generated by metabolic activity. With electrolyte balance‚ it involves balancing the amounts of absorption across the digestive tract with amounts of loss at the kidneys. Everyday
