  • Volume 2 of the four-volume The Facts On File Encyclopedia of Health and Medicine presents the body systems that nourish, cleanse, and protect the body. These are the systems of cells and fluids and the structures that transport them throughout the body. Though distinct in their functions and purposes, these systems overlap and integrate with one another in inseparable ways. The Cardiovascular System Volume 2 opens with “The Cardiovascular System,” the structures and functions that carry blood throughout the body.

  • Chapter 4 - Blood and the cardiovascular system. This chapter commences with an overview of basic cardiovascular function, identifying the main anatomy and physiological functions of this system. Common diseases that affect the ability of the system to function will be explored, illustrating how an individual’s ability to perform the basic functions of life can be compromised; ultimately these diseases can result in the individual’s lifespan being shortened.

  • The study of the heart and vessels by Magnetic Resonance Imaging represents a relatively new field of application, especially if one considers the large-scale diagnostic use of the technique in the neurological and muscular fields. The explanation of the delayed application in the cardiovascular field can be sought in the methodological complexity linked to the study of moving anatomical structures.

  • In addition, the distributions of deaths by age and by cause in Delhi are very different from those in the U.S. In the U.S., over 70 percent of all deaths occur after the age of 65. In Delhi, over 70 percent of all deaths occur before the age of 65, with over 20 percent occurring before the age of five. Furthermore, 46 percent of all non-trauma deaths in the U.S. are attributable to cardiovascular disease compared to only 23 percent in Delhi.' Because the main effects of acute exposure to air pollution on daily deaths occur through impacts on...

  • The heart, located in the mediastinum, is the central structure of the cardiovascular system. It is protected by the bony structures of the sternum anteriorly, the spinal column posteriorly, and the rib cage. Clinical Tip:The cone-shaped heart has its tip (apex) just above the diaphragm to the left of the midline. This is why we may think of the heart as being on the left side, since the strongest beat can be heard or felt here.

  • All living cells require metabolic substrates (e.g., oxygen, amino acids, glucose) and a mechanism by which they can remove byproducts of metabolism (e.g., carbon dioxide, lactic acid). Single-cell organisms exchange these substances directly with their environment through diffusion and cellular transport systems. In contrast, most cells of large organisms have limited or no exchange capacity with their environment because their cells are not in contact with the outside environment.

  • Previous chapters emphasized physiologic concepts concerning cardiac and vascular function at the cellular and organ level. In addition, they examined mechanisms, such as baroreceptors and circulating hormones, that regulate overall cardiovascular function. This chapter integrates all the components of the cardiovascular system and shows how they work together to maintain normal perfusion of organs under conditions of increased organ demand for blood flow (e.g., during exercise and pregnancy) or during abnormal stressful conditions such as hemorrhage....
