Cardiovascular System
The cardiovascular system plays a vital role in circulating blood throughout the body to maintain human life. The system consists of a heart and blood vessels that help delivers blood containing oxygen and nutrients to the body organs and tissues for function. The heart is a muscular body organ located on the left side of a human chest. The heart has four chambers are known as the right atrium, right ventricle, left atrium and the left ventricle. Blood travels through the four chambers by the heart muscle contracting and relaxing pumping blood to the body and lungs. Blood vessels such as the arteries and veins are what transport the blood away from the heart and to the heart. The arteries transport blood away from the heart to the body organs,

    Bio 202 Exam 1: Summary

    The cardiovascular system consists of : heart (심장), and vessels (혈관), arteries (동맥), capillaries (모세혈관) and veins (정맥). A functional cardiovascular system is vital (필수적인) for supplying oxygen and nutrients to tissues and removing wastes from them. Paths of Circulation: Pulmonary(폐의) Circuit : carrying blood to the lungs and back 1. The pulmonary circuit is made up of vessels that convey blood from the right ventricle to the pulmonary arteries to the lungs, alveolar capillaries, and pulmonary veins leading from the lungs to the left atrium. 2. Carries the deoxygenated blood away from the heart to the lungs, and there by it brings the oxygen containing blood from lungs to the heart. Systemic Circuit : carrying blood from the heart to the rest of body 1. The systemic circuit includes the aorta (대동맥) and its branches leading to all body tissues as well as the system of veins returning blood to the right atrium. 2. Carries the oxygenated blood from the heart to the body, and also brings back the deoxygenated blood from the body to the heart. Structure of the Heart A. Size and Location of the Heart 1. The heart lies in the mediastinum under the sternum; its apex extends to the fifth intercostal space. 2. Approximately the size of the fist (주먹) 3. Location - Superior surface of diaphragm - Left of the midline - Anterior to the vertebral column, posterior to the sternum Coverings of the Heart 1. The pericardium(심장막) which encloses the heart. - Protects and anchors the heart - Prevents overfilling of the heart with blood - Allows for the heart to work in a relatively friction-free environment 2. It is made of two layers: I. The outer, tough connective tissue fibrous pericardium II. visceral pericardium (epicardium; 외심막) that surrounds the heart. 3. At the base of the heart, the visceral pericardium folds back to become the parietal pericardium that lines the fibrous pericardium. 4. Between the parietal and visceral pericardia is a potential space (pericardial cavity) filled…

    The heart is what some determine to be the most important organ in our bodies and one of the biggest contributors. It is one of the major organs that if we did not have, it would not be possible for us to live. The heart is about the size of a fist and is broken down into four chambers, the aorta, superior vena cava, pulmonary artery, and the coronary artery. The four chambers include the right and left atrium and the right and left ventricle. The heart is responsible for supplying oxygen and blood to the entire body. Blood passes through these four chambers and then exits and pumps into the rest of the body. The heart also has three layers of walls…

    p4 explain the physiology of two named body systems in relation to metabolism

    The myocardium, commonly referred to as the heart, acts as a pump for transporting blood around the body via a collective system, known as the cardiovascular system. This system has various components; blood vessels; mainly arteries, veins and capillaries. The cardiovascular system has four main functions within the body. Firstly to transport dissolved oxygen, hormones, nutrients, salts, enzymes and urea to cells located around various places within the body, whilst at the same time eliminating any waste products such as carbon dioxide and water. Secondly, to protect the body from infection and blood loss. Thirdly, to distribute heat around the body to enable a healthy temperature of 37oc and finally to aid the body to maintain fluid balance. This ‘human pump’ can be regarded as two pumps. The fist sized organ contains two muscular chambers; the upper chamber; the atrium and the lower; the ventricle. The right side of the heart pumps deoxygenated blood from the veins to the lungs for oxygenation, whilst the left side pumps oxygenated blood from the lungs to the body. It is important to note that the two sides are separated by a septum. The blood flows through the heart twice within one cycle, this is known as ‘double circulation’.…

The blood carries food and oxygen to the cells and carries away carbon dioxide and waste materials. The right hand side of the heart receives de-oxygenated blood from the body tissues, and pumps it to the lungs. The left-hand side of the heart receives oxygenated blood from the lungs and pumps it into the body, so that the oxygen can be delivered to cells.…

The term “cardio” is derived from “cardiac” meaning Heart and the term “vascular” means blood vessels. So the name itself indicates that cardiovascular systems is the system of heart and blood vessels. Cardiovascular system is also known as “Circulatory System”. Cardiovascular system is made up of three major components; Heart, Blood vessels and blood. The heart is a hollow muscular organ made of strong cardiac muscles. The heart can push the blood through the circulatory system with great force. In fact push of the heart is the major force that causes circulation of blood throughout human body. Heart is made up of three layers; Pericardium, Myocardium and Endocardium. Human beings, unlike other some other species, have a closed circulatory system which essentially means that blood does not come into direct contact with body tissues. Rather, the blood flows in restricted pathways…

The Circulatory System is the core transference and cooling system for the body. The heart is located in the midpoint of your chest considerably to the left. The heart contains four wall chambers that blood flow throughout the heart. The valves of the heart forces blood to flow throughout the ventricles into the arteries to prevent blood from backing into the arteries. The heart beats between 60 and 100 beats per minute.…
