Short report

Cardiac Arrest The circulatory system along with the heart make are what make up the cardiovascular system. The heart works as a pump that pushes blood to tissues, organs and cells in your body. The blood can be pumped throughout the body through a series of arteries, veins and capillaries. Arteries and capillaries send blood from the heart to all areas of the body, while veins help bring that blood back to the heart. Arteries carries oxygenated blood away from the heart, and veins carry deoxygenated blood back to the heart. This process is called circulation. The roles are revered in pulmonary circulation. The pulmonary arteries bring deoxygenated blood to your lungs, while the pulmonary veins will bring

    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…

    Blood is the liquid that flows through various vessels in our body. The teacher demonstrates a drawing of how when the doctor takes plasma from our body how it is mixed into a small tube. The materials that are used are red blood cells, white blood cells, and platelets. In the tube the combination of the two liquids is called blood. The liquid (plasma) is on the top and the materials are on the bottom. We discussed why the heart is important and what it does. The heart is important because it pumps the blood through our body and how the vessels travel to and from the heart. The heart has two parts the right and left atrium, they send oxygen blood to lung and is a power circulation the body. We talked about the 2 types of Circuits (pulmonary and systemic). The pulmonary circuit pumps blood to the lungs and back, where the red blood cells can get oxygen while the systemic circuits blood pump from the heart to the body tissues and back. Another part we learned about being the vessels and three parts. According to google online dictionary the blood vessels are the part of the circulatory system that transports blood throughout the human body. We discussed the three parts the vessels consist of, arteries, veins, and capillaries. An artery (red blood) is a larger blood vessels that carry blood ways from the heart, veins (blue) is a large blood vessel that carry blood back to the heart and capillaries is the smaller blood vessels to smaller body…

    Assignment: How Two Body Systems Interrelate to Perform Named Functions

    The circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body organs and returns with deoxygenated blood.…

    The main parts of the cardiovascular system are the heart, blood and the blood vessels (arteries and veins). The function of the heart is to pump blood around the body. The function of the blood is to supply nutrients and oxygen to the cell. The blood vessels (arteries and veins) role is to transport blood to and from the heart. However, the general function of CVS is to remove waste products such as CO2 and protect the body, for example the white blood cells in the body. “It also distributes heat around the body and assists in temperature regulation and helps regulate water.”…

    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’.…

    Heart is associated to cardiovascular system, heart is also known as the blood-pump of the body. It pumps blood through the circulatory system to all parts of the body. 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.…

    How the cardiovascular and respiratory systems are linked chloes work

    Oxygen is carried through the blood via capillaries and veins (cardiovascular system) and is entered into the body by breathing it in (respiratory system) it then travels down the lungs (as explained in the first paragraph) until it reaches the alveoli, its then diffused into the blood but due to oxygen not being able to dissolve easily, most of it is carried by the haemoglobin in red blood cells and then transported into the parts that need a supply of oxygen e.g. if aerobic respiration is being carried, the working muscles will need a good supply of oxygen to prevent fatigue and to allow them to carry on working for longer until a limiting factor. Without the cardiovascular system then the oxygen taken into the lungs via the respiratory system will have nowhere to be transported to which means the heart and other vital organs wouldn’t be getting their supply of oxygen, so it shows that both systems are linked together for either to actually work.…

    The human transport system is a system of tubes with a pump and valves to ensure one way blood flow. We need a transport system to deliver oxygen, nutrients and other substances to all our body cells, and take away waste products from them. The oxygenated blood (high in oxygen, red in color) comes to the heart from the lungs in the pulmonary vein; the heart pumps it to the aorta (an artery) to the rest of the body. The deoxygenated blood returns to the heart from the body in the vena cava (a vein), the heart pumps is to the lungs to get rid of the carbon dioxide. Oxygenated Blood: Red color, high oxygen low Carbon dioxide. Deoxygenated Blood: Blue color, low oxygen high Carbon dioxide. Did you notice that during one circulation, the blood went through the heart twice, this is why we call it double circulation. When the blood is flowing away from the heart, it has a very high pressure, when it is flowing towards the heart it has a lower pressure.…

    The heart lies in the thoratic cavity, organs associated with the heart are inferiorly, the hearts apex rested on the tendon of the diaphragm, superiorly, the great blood vessels, posteriorly the oesophagus, trachea and the left and right bronchus, laterally, the lungs and anteriorly the sternum and ribs. (Waugh& Grant 2014). The heart provides a constant blood circulation action and the blood vessels provide a network for the blood flow. The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body, ( www.le.ac.uk) the right side of the heart pumps blood to the lungs (pulmonary circulation) and the left side receives oxygenated blood and supplies it to the rest of the body (systemic circulation). There are three types of blood vessel, arteries, capilleries and veins. Blood is pumped from the heart through the arteries at high pressure which could damage the tissue so it needs to go through the capillaires which are smaller low pressure blood vessels that are responsilbe for providing oxygen to the tissues, they also absord excess carbon dioxide and then deliver the blood into the veins which then supply the blood back to the heart. The heart generates its own electrical impulses, it does not rely on any other external mechanisn to make it beat. A normal heart rate is 60-80 times per minute, factors which can decrease or…
