(Heart Failure, 2015, para. 2) The American Heart Association and American College of Cardiology defines heart failure as “a complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricles to fill with or eject

para. 8) A drop of blood contains large amount of red cells and each cell contains millions of molecules of hemoglobin. Circulatory system transports blood and oxygen from the lungs to the rest of the body. The average sized adult carries about 9 pints of blood. (Circulatory System, n.d para. 1) An extension of the human circulatory, the lymphatic system, includes cell-mediated immune systems.

B.) Nutrition- absorbs and carries nutrients from food substance to the cells of the body. C.) Waste removal- disposes of waste products and toxins that are harmful if they accumulated. D.) Immunity-Helps in protecting the body from diseases.
