movement both internal and external allowing for the continuous cycle that keeps the human body functioning. The most important system that relies on movement is the Cardiovascular system. The Cardiovascular system is mainly composed of the heart, blood vessels, and about 5.5 liters of blood. ()The system itself is constantly moving, internally and externally.() The heart itself is a muscular pumping organ that helps with the transport of oxygen and waste via the blood system. () Specifically the pulmonary

condition. The leading causes of heart disease and stroke are high blood pressure

Unit 11 Assignment 2: Cardiovascular and Respiratory Systems M2. Explain the need for a transport system in a multi-cellular organism There are two types of cellular organisms: • Unicellular organism • Multi-cellular organism Unicellular Organism A unicellular organism is a single celled organism (one cell), which is to rely on the process of diffusion, when moving different substances in and out of other cells, due to its structure it has a larger surface area in comparison to its volume; this

infection and foreign bodies (Glover, 1997). The cardiovascular system is composed of the heart and its vessels. The heart is an involuntary muscle which receives blood to the atrias, which is then pumped via the ventricles. The vessels are composed of three main types. Arteries, veins and capillaries; all which transport blood throughout the entirety of the body. The constant action of both the vessels and heart ensure that the body receives a continuous supply of blood, keeping us within our homeostatic

presents the lecture “Stroke Education Seminar – Signs, Symptoms and treatment." The lecturer starts with the concept of a stroke; that can be an obstruction of blood flow to some area within the brain; that is the ischemic stroke, or a rupture of a vessel inside the brain, that is the hemorrhagic stroke. Then, the manifestations of a stroke depend on the affected brain area, and if this area is responsible for sensation, motion, speech or visual function, the manifestation will correspond to loss of

local response consist of vascular response and cellular response. shortly after the injury has occurred there is brief construction of blood vessels which may last for five minutes. this is replaced by dilatation if the vessel occurring within thirty minutes of the injury. the dilatation of the blood vessels account for increased blood supply -(hyperaemia) and increased permeability of the venular and the capillaries. Exudation (escape) of some cells and fluid (plasma) into

the human figure in seeing that the aforementioned contracts and expands. Furthermore, each time the heart contracts it does so with all its dynamism. The pumping of the heart is titled the Cardiac Cycle. The heart pumps blood, retains our blood pressure, and eradicates the waste products. For example, the brain requires oxygen with glucose, which, if not received continuously, will cause it to lose cognizance. Essentially, if the heart was to fail, consequently the entire form would shut down in

The circulatory system consists of blood contained in a network of vessels called the vascular system. The above figure is a schematic of the human circulatory system, the heart pumps oxygenated blood from the left side to different parts of the body and returns back to the right side of the heart making a closed loop, this loop is called the systemic circuit. The blood from the heart is pumped into large muscular arteries from which it moves into smaller arteries and finally into the areole from

blood vessels in our body. It includes the veins, arteries and capillaries for the blood circulation in the entire body (to and from the heart). And if any issue occur in the vascular system, then it will cause the disastrous outcomes. As the illustrations, if the arteries can become thick and stiff, then a problem called atherosclerosis will arise. Or, if it is the blood clotting, then it will clog the vessels and cease the blood flow to the heart or brain. Or, if the weakened blood vessels can burst

and right ventricles. Venous and arterial compliances are modeled by air and water tanks, while tygon tubes are used to model flow resistance of the venous, arterial flows. The variation in system resistance characteristics under different cardiac pressure and flow conditions are modeled by a tuning clamp. The mock circulatory loop was tuned to simulate several pathological and normal cardiovascular activity state of a person unlike the older mock circulatory loops. Different human activity rates like
