Lydia R Leonardo DrPH Biology 133 The Human Heart The first functional organ to develop Begins beating and pumping blood around day 21 or 22 a mere three weeks after fertilization Emphasizes the critical nature of the heart in distributing blood through the vessels and the vital exchange of nutrients oxygen and wastes both to and from the developing baby . 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 .

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.. Heart and circulatorydiseaseis an umbrella term forall diseases of the heart and circulation. It includes everything from conditions that are inherited or that a person is born with, to those that dev blood vascular system. is composed of the following structures:. The . heart,. an organ whose function is to pump the blood.. The . arteries,. a series of efferent vessels that become smaller as they . The main role of the circulatory system is to bring oxygen, nutrients such as sugar to the cells and remove waste products such as carbon dioxide.. Multicellular. organisms , or living things made of many cells need a system to deliver oxygen and food and remove wastes in order to survive..
