As health research and technology continue to advance, more information about the human body is being discovered. Anyone who is pursuing higher education about the human body and how it performs receives advanced information about the human circulatory system. This system is the combination of the body's organs and tissues working together to transport blood, oxygen, and nutrients throughout the body. A pamphlet would benefit a biology or medical student because it would be a tool for learning and studying.

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Did you know that the average adult has about 60,000 miles (95,500 kilometers) of blood vessels? Blood flows through the body in two circuits, or pathways, that begin and end at the heart. Discover more fascinating facts in Circulatory System, a title in the Body Systems series. Each title in Body Systems guides readers through the fascinating inner workings of the human body. The human body contains several complex systems that work closely together to support fife and allow the body to function properly. Each book explores the characteristics and interactions of these systems, their makeup, and their importance. This is an AV2 media enhanced book. A unique book code printed on page 2 unlocks multimedia content that brings the book to life. This book comes alive with audio, video, weblinks, slideshows, activities, quizzes, and much more.
