1) The Cardiovascular System
The Cardiovascular system is constructed of the heart, blood vessels (arteries, veins and smaller vessels) and the blood.
The body needs this system to transport oxygen, nutrients and waste to the body 's tissues to maintain homeostasis (active process that maintains a constant internal environment despite external changes). (Tortora 1996)

The illustration shows the transport of blood to the body. The arteries and arterioles (Red) and veins and venules (Blue). However, there are some exceptions: the Pulmonary veins, the Pulmonary arteries and the capillaries.

The body also has two types of circulations:
The Pulmonary circulation takes deoxygenated blood from the heart to the lungs, picks up oxygen and goes back to the heart.
The oxygenated blood is then transported to the rest of the body before returning to the heart via the Systemic circulation. During this process blood goes to the stomach, intestines, spleen and pancreas, these have their own set of blood vessels (Hepatic portal vein and artery and the mesenteric veins) where absorption of nutrients and removal of toxins and waste takes place. (Ross & Wilson 2011)

    Blood enters the heart through the Superior Vena Cava which is the large vein at the top of the heart, and the Inferior Vena Cava, which is the large vein at the bottom of the heart. Blood flows into the right atrium, passes through the tricuspid valve, and makes its way into the right ventricle. It then moves through the pulmonic valve, into the pulmonary artery to the lungs.” After picking up oxygen in the lungs, the blood moves out of the lungs into the pulmonary vein, into the left atrium, through the mitral valve, and into the left ventricle that pushes blood to the body through the aortic valve. Once blood leaves the heart it is in the aorta where it flows to various parts of the body” (Whitlock, J. 2017).…

    A deoxygenated red blood cell coming from the body would enter the heart from the vena cava into the right atrium. It would then go into the right ventricle through the tricuspid valve. From the right ventricle, it would be pumped to the lungs through the pulmonary artery. The red blood cell would be oxygenated in the lungs and would return to the left atrium through the pulmonary vein. From the pulmonary vein, it would go through the bicuspid valves into the left ventricle and the left ventricle would pump it through the aorta to the rest of the body.…

    Right Ventricle- Inferior to the right atrium and it receives deoxygenated blood and ejects it into the pulmonary trunk or pulmonary artery. (Pulmonary trunk branches into right and left pulmonary arteries, which deliver deoxygenated blood to the lungs through a series of vessels called the pulmonary circuit).

    The blood then travel to the lungs where it will receive the oxygen to continue the process of circulation. Later, it drains out of the lungs via the pulmonary veins and then travels into the left atrium. While the blood is forced out through the aortic semilunar valve and into the aorta. The aorta and its branches carry blood to all the tissues of the body system. Reference, Essential of Human Anatomy and Physiology, 2012, by Elaine N.

    The flow of blood begins in the right atrium where it is deoxygenated. From there it goes to the tricuspid valve, right ventricle, pulmonary valve, pulmonary trunk and arteries, pulmonary capillaries (where the blood loses carbon dioxide and gains oxygen), pulmonary veins, left atrium, bicuspid valve, left ventricle, aortic valve, aorta and systemic arteries, systemic capillaries (where the blood loses oxygen and gains carbon dioxide), super vena cava, inferior vena cava, and coronary sinus, back to the right atrium.…

    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.…

    Breifly Describe the Importance of the Interaction Between the Interaction Between the Respiratory System and Cardiovacular System in Maintaining the Body's Internal Balance

    Oxygenated blood, which is pumped through the body via the arteries, supplies the body's tissues with oxygen that they need to live. Blood in the arteries is under high pressure; however, which could damage the tissue, so this oxygenated blood first needs to go to the capillaries, which are very small and low-pressure blood vessels that are responsible for supplying the oxygenated blood to the tissues. . Once the capillaries have delivered their oxygen, they also absorb excess carbon dioxide into the blood and then deliver it to the veins, which then supply the blood back to the heart.

    Blood transport happens in the circulatory system. The oxygenated blood gets transported from the lungs to the left atrium of the heart by the pulmonary vein. It then travels around the body by the aorta which sends it to the whole body. When the travelling is finished the oxygenated blood is now deoxygenated blood. The deoxygenated blood then travels back to the lungs by the vena cava to the right atrium into the heart. Now deoxygenated blood has reached the heart, the pulmonary artery carries the blood to…

    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 Cardiovascular System: The Circulatory System

    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.…
