Cardiovascular system

The cardiovascular system is an integral system responsible for maintaining homeostasis in the body. It is composed of the muscular pumping organ, the heart, and a closed system of vessels called arteries, veins, and capillaries. “A baby 's heart begins to develop at conception, but is completely formed by eight weeks into the pregnancy” (Stanford Children’s Health). As the heart reaches structural and functional maturation, it will involuntarily pump blood to the blood vessels to nourish cells…

Cardiovascular System Have you ever felt your heart racing before a big exam? How about after running a marathon? That fast, steady pace, making you breathe heavily. This is part of your cardiovascular system. A larger system made up of your heart system and circulatory system. The heart works to push out about 5 liters, on average, of blood every minute, to the organs, tissues and cells of the human body. This hard working organ, fully matured is only about the size of your clenched fist. Each…

A PMI located outside these landmarks indicates possible cardiac enlargement, such as with left ventricular hypertrophy. Cardiac enlargement is not necessarily associated with atherosclerosis or carotid artery disease. DIF: Cognitive Level: Apply (application) REF: 697 TOP: Nursing Process: Assessment MSC: NCLEX: Physiological Integrity 4. To auscultate for S3 or S4 gallops in the mitral area, the nurse listens with the a. bell of the stethoscope with the patient in the left lateral position. b.…

M1 outline the adaptations to cardiovascular, respiratory, musculoskeletal and energy systems, brought about by regular exercise Cardiovascular System The cardiovascular system consists of the blood vessels and the heart. They function is to circulate the blood around the body to all the muscles. The red blood cells carry oxygen to all the muscles through the vein (carries blood to the heart). The veins have thin walls and contain blood under the low pressure. The arteries (carries blood away…

- Inner Layer; An inner endothelial cell layer called tunica intima lines the arteries and veins. The tunica intima, is a single layer of squamous epithelial cells that lines the inner surface of the entire cardiovascular system. In many veins, the tunica intima is equipped with pockets that act as one-way valves. These valves prevent the back flow of blood and allow the veins to act as supplemental pumps that help to keep the blood following in one direction, back toward the heart. The activity…

Article Critique In the article, Case management to reduce risk of cardiovascular disease in a county health care system, Ma et al. (2009) acknowledge that given the hundreds of billions spent in addressing the cardiovascular disease (CVD), embracing innovative approaches is necessary to supplement the conventional healthcare models. Besides, they recognize that the CVD, along with its causative factors, affects individuals across different ethnic, social class, and racial groups. However, they…

transport blood from the heart to the systemic circulation, and veins that transport blood back again into the heart. A remarkable change in blood vessel structure and function happened, with the emergence of a high-pressure, pulsatile circulatory system in vertebrates. Blood vessels then evolved from simple tubes for channeling blood or other body fluids from a low-pressure heart. According to their sizes and structures, arteries can be subdivided into four categories: large elastic arteries,…

The Autonomic Nervous System also influences metabolism and thermal regulation. There are three main parts of the Autonomic Nervous System: the sympathetic nervous system, enteric nervous system, and parasympathetic nervous system. Ganglions are components of the autonomic nervous system and therefore has preganglionic and postganglionic fibers. Sympathetic Nervous System has thoracombular outflow. On stimulation of the body, its effects are widely spread across the body system. This is in…

Heavy Drinking and Increased Cardiovascular Risk The article ‘Heavy drinking may raise cardiovascular risk by aging the arteries’ by Ana Sandoiu establishes that the excessive alcohol abuse could potentially lead to cardiovascular problems in the future. In this news article, alcohol consumption is an environmental factor, and arterial stiffness is the developmental outcome. This news article is based on the research ‘Twenty-five-year alcohol consumption trajectories and their association with…

Article 69: Ayurvedic Management of Hridroga Introduction The cardiovascular system consists of the heart and blood-vessels (with their contained fluid, blood). The heart is a muscular organ and pumps blood to all parts of the human body by the process of contraction. Pure-.oxygenated blood is carried by the dhamani (arteries) and impure-deoxygenated blood by the sira (veins). Some common cardiac ailments and there Ayurvedic management is discussed below High blood pressure (Hypertension)…
