PPT-Circulatory System – General Aspects

In small invertebrate organisms no circulatory system is necessary as diffusion distances are short With greater size diffusion from the external environment becomes insufficient and a circulatory system is required to transport materials within the body. It also returns oxygen poor blood to the lungs The circulatory system consists of The heart w hich pumps blood into the vessels Blood vessels tubes that carry blood to your en tire body and back to the heart The lungs which supply oxygen to the bloo The blood delivers nutrients and oxygen to your cells and removes waste products and carbon dioxide The heart ensures that blood flows constantly by pumping it through the blood vessels Blood vessels are tubes of all different sizes that transport b and .

General Functions of the Circulatory System Heart: The heart plays an important role because it keeps all the blood flowing in the circulatory system.
