The Heart Work

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.

Provides a simple introduction to how the heart and circulatory system work.

Burnout is common among doctors in the West, so one might assume that a medical career in Malawi, one of the poorest countries in the world, would place far greater strain on the idealism that drives many doctors. But, as A Heart for the Work makes clear, Malawian medical students learn to confront poverty creatively, experiencing fatigue and frustration but also joy and commitment on their way to becoming physicians. The first ethnography of medical training in the global South, Claire L. Wendland’s book is a moving and perceptive look at medicine in a world where the transnational movement of people and ideas creates both devastation and possibility. Wendland, a physician anthropologist, conducted extensive interviews and worked in wards, clinics, and operating theaters alongside the student doctors whose stories she relates. From the relative calm of Malawi’s College of Medicine to the turbulence of training at hospitals with gravely ill patients and dramatically inadequate supplies, staff, and technology, Wendland’s work reveals the way these young doctors engage the contradictions of their circumstances, shedding new light on debates about the effects of medical training, the impact of traditional healing, and the purposes of medicine.

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.

Nine simple mindfulness practices anyone can use to generate compassion--toward oneself, others, and the world--and to live from that place of intelligent kindness in the face of life's difficulties. Compassion is the urge to understand and alleviate the suffering of another being. And if that being happens to be you, then the technique called self-compassion can be the greatest of blessings—for the compassion you learn to apply to yourself naturally extends to all the other people in your life. With the nine simple mindfulness practices she presents here, Radhule Weininger provides a step-by-step course in self-compassion. Using stories drawn from her own life and those of others she shows that, with the right intention and practice, we can all deepen our capacity to respond skillfully to our own suffering and thus to that of others and our world.
