Circulatory System
Abstract This paper will contain some important and main information about humans’ circulatory system. One of the most important systems our body has if not THE most important since one of its organs is the heart. We will focus on senior citizens. As we age, our organs’ working mechanism becomes slower and our muscles tend to be less flexible or elastic and that is why we think the information we will provide, will be very useful. Some of the talking points will be:
• General function of the system and how the organ system contributes to physiological homeostasis of the human organism
• How the organ system (circulatory) does interacts with other organ systems in the human body.
• Organs in this system and its functions.
• Representative organ – its structure (including cells and tissues) and how the structure relates to the specific function of the organ.
• One disease and how it affects the system and human health.

The Circulatory System The circulatory system circulates blood throughout all the organs in the human body; and blood delivers oxygen and nutrients to every single cell and picks up waste and carbon dioxide from these cells it passes through. The heart (main system’s organ) pumps blood to the organs, cells and tissues of your body through arteries, arterioles, and capillaries and it is sent back to the heart through veins and venules (Texas Heart Institute, 2010).
The human body has a closed circulatory system where blood is confined to the heart and blood vessels which branch elaborately throughout the tissues and organs of the body to allow exchange of nutrients and wastes. The circulatory system performs the following functions which contribute to the physiological equilibrium of the human organism and interaction with other systems such as digestive, lymphatic, respiratory (lungs), etc:
• Transports oxygen from the lungs and gills to the tissues, and transports carbon dioxide from the tissues to the lungs or gills.

    The main function of the respiratory system is gaseous exchange. This refers to the process of Oxygen and Carbon Dioxide moving between the lungs and blood. This occurs during gaseous exchange as the blood in the capillaries surrounding the alveoli has a lower oxygen concentration of Oxygen than the air in the alveoli which…

    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 cardiovascular system which impacts deeply on human consciousness. The heart and the body’s blood-transporting network of arteries, veins, and smaller vessels form the circulatory or cardiovascular system. As blood is continuously pumped out from the heart and around the system in two circuits, it carries oxygen and vital nutrients to all parts of the body and removes harmful waste products from tissues.

    The heart is a muscular pump that makes blood around the body through a system of blood vessels (arteries, veins and capillaries). Blood carries dissolved oxygen to the body cells and at the same time removes the waste products of respiration (carbon dioxide and water). Blood is also important in distributing heat around the body, along with hormones,…

    The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed through the mouth and nostrils into the lungs. The gas then diffuses through the alveolar walls and into red blood cells (erythrocytes). Carbon dioxide carried back within red blood cells diffuses back through the alveolar walls and is exhaled out through the mouth.…

    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…

    The Circulatory System is the main transportation for the body, made up of blood vessels, the blood and the heart. The blood is comprised of the red blood cells, white blood cells (lymphocytes and phagocytes which make up part of the immune system, engulfing invading pathogens), platelets which help the blood to clot preventing infection all transported around the vessels amongst the plasma. The blood plasma contains dissolved substances including carbon dioxide, urea and nutrients.…

    The cardiovascular system, also known as the circulatory system, is composed of the heart, blood vessels, and blood. The term cardiovascular refers to the heart (cardio-) and blood vessels (vascular). The term circulatory refers to the circulation of the blood. The heart is a muscular pump and its regular contractions send blood into tough, elastic tubes called arteries, which branch into smaller vessels and convey oxygen-rich blood through the body. The arteries eventually divide into tiny capillaries, which have such thin walls, that oxygen, nutrients, minerals, and other substances pass through to surrounding cells and tissues. Waste substances flow from the tissues and cells into the blood for disposal. The capillaries join and enlarge to create tubes that eventually become veins, which take blood back to the heart. Vessels carrying oxygenated blood (usually arteries) are shown in red and those carrying deoxygenated blood (usually veins) are blue.…

    The cardiovascular system, also known as the circulatory system, consists of the heart, blood vessels and approximately 5 litres of blood. 55% of the blood is straw coloured yellow and 45% of the blood is made up of red and white blood cells and tiny particles called platelets. This system is powered by the heart and is responsible for transporting oxygen, nutrients, hormones and cellular waste throughout the body. Oxygen is very important to blood and to the cells as it is necessary for cell growth and energy. Red corpuscles (red blood cells) transport oxygen to the body’s cells and carry away carbon dioxide from the cells. Inside the blood there is plasma. The plasma carries minerals, vitamins, sugar and other foods to the body’s cells.…

    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…
