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.

Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

How do you fight despair and learn to meet the world with a loving heart? How do you overcome shame? Stay faithful in spite of failure? No matter where people live or what their circumstances may be, everyone needs boundless, restorative love. Gorgeous and uplifting, Tattoos on the Heart amply demonstrates the impact unconditional love can have on your life. As a pastor working in a neighborhood with the highest concentration of murderous gang activity in Los Angeles, Gregory Boyle created an organization to provide jobs, job training, and encouragement so that young people could work together and learn the mutual respect that comes from collaboration. Tattoos on the Heart is a breathtaking series of parables distilled from his twenty years in the barrio. Arranged by theme and filled with sparkling humor and glowing generosity, these essays offer a stirring look at how full our lives could be if we could find the joy in loving others and in being loved unconditionally. From giant, tattooed Cesar, shopping at JCPenney fresh out of prison, we learn how to feel worthy of God’s love. From ten-year-old Lula we learn the importance of being known and acknowledged. From Pedro we understand the kind of patience necessary to rescue someone from the darkness. In each chapter we benefit from Boyle’s wonderful, hard-earned wisdom. Inspired by faith but applicable to anyone trying to be good, these personal, unflinching stories are full of surprising revelations and observations of the community in which Boyle works and of the many lives he has helped save. Erudite, down-to-earth, and utterly heartening, these essays about universal kinship and redemption are moving examples of the power of unconditional love in difficult times and the importance of fighting despair. With Gregory Boyle’s guidance, we can recognize our own wounds in the broken lives and daunting struggles of the men and women in these parables and learn to find joy in all of the people around us. Tattoos on the Heart reminds us that no life is less valuable than another.
