Circulatory system is an organ system that transports things around the body that are needed by cells. For example: Nutrients‚ such as: Oxygen‚ Food and Water. When Blood circulates around the body‚ it leaves the left ventricle of the Heart and travels to the Aorta (The largest artery in the Human body). The blood that leaves the Aorta is rich of oxygen then travels around the body in arteries‚ and to the organs. When the deoxygenated blood travels back to the lungs through a system of Veins‚ As

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
