u03a1 Heart and Lungs Dr. Henry Zeidan 10/30/12 Todd Jones The heart is a hard working muscle responsible for pumping blood throughout blood vessel via continuous rhythmic contractions. It exists in all living things having a circulatory system (Maton, 1993). Function of the Heart The right ventricle The right ventricle is the pumping chamber of the pulmonary circuit. The mechanism of the right ventricle is that, deoxygenated blood flows to the right atrium from veins that are in the body

Differentiate Living things from non-living things according to: Organization All living organisms have a definite shape and size as well as physical and chemical composition inherited from their parents. This is possible because of a high degree of organization. The molecules of which an organism is made up are organized into cells, which in turn are organized into tissues, organs and organ systems making the whole individual. This kind of complex organization is not found in non-living things

blood throughout the body. How It’s Connected to Other Parts in the Body It supplies oxygen and nutrients to our bodies by working with the respiratory system. At the same time, the circulatory system helps carry waste and carbon dioxide out of the body. Hormones — produced by the endocrine system— are also transported through the blood in the circulatory system. Pacemaker: The pacemaker is a group of cells in the right atrium. By sending a signal that makes heart muscle cells contract, the

not and cigarettes are easily accessible to almost anyone who wishes to partake, so informing people of what they are doing to themselves and the people around them is the first line of defense against this killer lifestyle choice. The human respiratory system is responsible for providing the body with oxygen and ridding it of carbon dioxide (Editorial Board, 2012).
