Cardiovascular Pathology The heart has many components to it and all of them are essential to keep the heart pumping. Three problems that can occur in a heart are atria or ventricles not functioning properly‚ the electrical activity‚ or coronary artery disease. While all of these problems are different they can all be deadly if left untreated. The heart is a very important organ and should be taken care of properly. When an atria or ventricle goes isn’t working right it completely changes your

1.1 The skin is the largest organ of the body and it acts as a waterproof protector for all the internal organs and it consist of four distinct layers: The epidermis‚ the basement membrane zone‚ the dermis and the subcutaneous layer. The epidermis which is the outer layer and is a protective multi-layered self-renewing structure which varies in thickness depending on which part of the body it covers. The dermis is underneath the epidermis‚ this is a layer of connective tissue which provides the

FROG MUSCLE PHYSIOLOGY 2) What was the smallest voltage required to produce max contraction? What proportion of the muscle fibers in the muscle do you think were contracting to produce this maximal response? Muscle fibers act in response to isolated stimuli in an all or none fashion. However‚ a muscle organ‚ such as the gastrocnemius muscle‚ is composed of many individual muscle fibers. It is known that all of the fibers in a muscle do not have the same threshold and that a stimulus applied to

ANATOMY AND PHYSIOLOGY Chronic Kidney Disease Cardiovascular System The cardiovascular system is sometimes called the circulatory system. It consists of the heart‚ which is a muscular pumping device‚ and a closed system of vessels called arteries‚ veins‚ and capillaries. As the name implies‚ blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various "circulations" of the body.
