Cardiovascular system consists of the heart and it’s associated blood vessels. “Main functions of the cardiovascular system include the supply of oxygen and nutrients to all cellular tissues in the body while also removing metabolic wastes such as carbon dioxide” (Collins, 2013 p. 169). The heart is a four-chambered organ with two superior atria and two inferior ventricles. There is four valves located in the heart each function to prevent the backflow of blood into either atria or ventricular chambers

The cardiovascular system is a network of arteries, arterioles, capillaries, venules, and veins that move blood to and from the heart, lungs and other body tissues. It can perform many important tasks that are essential to the survival of the human body. When talking about the cardiovascular system, the main organ that is involved is the heart. The heart consists of four chambers that assist in the transport of blood throughout the human body. The right atria receives deoxygenated blood, from

ballooning of a blood vessel, or even an embolism (when any foreign body enters the blood stream). Blood vessels include arteries, capillaries and veins and therefore these events can occur anywhere in the body (i.e. the heart or the brain). There are different types of aneurysms including saccular, fusiform and pseudo-aneurysms. Saccular aneurysms only develop on part of the vessel wall and are spherical in shape. Fusiform aneurysms are ovoid in shape and develop over the entire vessel cross section.

consists of the heart and blood vessels circulating blood throughout the body, delivering water, oxygen, and nutrients to cells, and removing waste products such as carbon dioxide blood vessels working together to is system”. (Wiley) And now for the Circulatory system is also a major function of our body, “The basic circulatory system of vertebrate animals, which are those with a backbone, consists of a heart, the blood and the arteries and system of blood vessels. The heart pumps the blood first

types of blood vessels in the systemic system are arteries, arterioles, capillaries, veins and venules. In this experiment, the main blood vessels that were explored in depth were the arteries and the veins. An artery is a muscular or elastic tube that carries oxygenated blood from the heart to the tissues of the body. The only exception to this is the pulmonary, which carries oxygen to the lungs for oxygenation and removal of excess carbon dioxide. A vein is a type of blood vessel that transports

of tubular vessels with a branched network allowing supply to all areas of organism - A means of controlling the flow to suit the needs of the organism What is blood pressure? Blood pressure is a measure of the pressure exerted by the blood against artery walls. Blood varies with heartbeat strength, age, blood volume, health and fitness. Blood pressure is measured as two numbers, e.g. 120/80 these numbers represent systolic and diastolic the big number is systolic which the blood pressure is during

the brain. Brain aneurisms or weak blood vessel leaks are examples of hemorrhagic stroke causes. Intracerebral Hemorrhage-blood vessels inside of the brain burst and leak surrounding brain tissue Subarachnoid Hemorrhage-caused by bleeding disorders, head injuries, and taking blood thinners Ischemic Stroke is death of an area of brain tissue that is a result of an inadequate blood and oxygen supply to the brain due to blockage of an artery. High blood pressure is the leading cause of this type of stroke

As an organism’s heart beats, it pumps blood throughout the body pushing the blood against the side of the blood vessels 1 . The strength of this push is called blood pressure. Blood vessels expand and contract as the temperature of the body changes. T his experiment is going to test the effect of water in different temperatures on blood pressure. As the body of a human immerse s in the water, different physical and chemical reactions happen throughout the body which influences functions of

Kemnitz and Tortora, 2010). Blood from the aorta flows into renal arteries of the kidney then through vessels that become progressively smaller towards the nephron. Nephrons are functional units of the kidney which

the risk factors. Race is also important in determining those at risk. African Americans have almost double the risk compared to Caucasians. High blood pressure is one of the leading causes of stroke. As many as 50 million Americans have high blood pressure and only 31 % know they have it. High blood pressure puts unnecessary strain on blood vessel walls causing them to thicken and deteriorate. Smoking almost doubles your risk of ischemic stroke and increases your risk of hemorrhagic stroke by 3.5
