The human body is an amazing machine, we have cells, tissues, organs and organ system that come together to create the human race. Each system plays a key role in our bodies mechanism. Without each systems our bodies would not function properly, but what happens when one of these system fails? The Cardiovascular system components are blood, blood vessels and the heart. The hearts function is to pump blood to all the major organs and tissues (Circulatory). It’s also important to be aware of the derivation that our bodies may encounter, for example a stroke. In this passage I discuss different types of strokes, what are the signs and symptoms and after care for this disorder of the cardiovascular system. Strokes occur when there is an insufficient …show more content…
Due to the lose in brain cells sometime facial nerve can become damage. Which is also a sign of a stroke. In stroke patient usually when ask to smile, only half of their facial muscle would be able to do so. While the other half remain drooped. The Circulatory system is affect as well. Remember in a Hemorrhagic stroke a ruptured blood vessel begins to bleed out into the brain. Once blood is secreted out side the blood vessel into the tissues, red blood cells will take away nutrient from the brain cells. In Ischemic, the blockage in the blood vessel does not allow the blood to circulated proper. As a result of lost blood supply brain cells will die in the area where it is not receiving nourishment. Traveling in our bloodstream is oxygen and glucose, which is constantly need for cells to preform they daily functions. A stroke can happen at any age but for patients who are 55 and older, their risk factor will increase due to age and physical activity. “While stroke is common among the elderly, a lot of people under 65 also have strokes”(“About Stroke” page 1). Also at risk are African Americans because of other health issues that can trigger a stroke, for example: high blood pressure, diabetes and obesity. Caucasians and Hispanics are also at. Not only does Ethnicity and age play a factor, but so does other health conditions. Patients who suffer from high blood pressure, diabetes, heart disease, obesity, alcohol and drug
Stroke occurs when the blood supply to the brain is blocked or condensed. Blood works to transport oxygen and other beneficial substances to the body’s cells and organs, as well as the brain. There are two main types of strokes that are known as Ischemic strokes and Hemorrhagic strokes. When the blood vessels that provides for the brain becomes congested, is it referred to as ischemic stroke, the most common stroke within adults. Blood clots, a cluster of blood that sticks together, are the cause of Ischemic strokes. Ischemic strokes also takes place when arteries become backed up with plague, leaving less blood to flow. Plague is cholesterol, calcium and fibrous and connective tissue that sticks to the walls of blood vessels. Ischemic strokes eternally damage the brain and cause a person's body to no longer function habitually.Some risk factors that may increase stroke are high cholesterol, diabetes, high blood pressure, and obesity. Some stroke factors are also due to old age or having a family that has a history of strokes. Men are more likely to have a stroke but the most st...
It goes without saying that everyone’s health is important and should be taken care carefully. Everyone has heard of strokes before but many people do not really know its meaning, types, and the number of individuals of that dies due to this issue. According to Centers for Disease Control and Prevention (2015), strokes kills an average of 130,000 people a year and it is one of the most common deaths that happen in the United States. An average of 800,000 of people die from cardiovascular disease and strokes and it is also a reason of long-term disability (Centers of Disease Control and Prevention, 2015). Strokes, which can also be called cerebrovascular accident or CVA happen when the blood supply to the brain is interrupted or the blood vessel going towards the brain burst. Then part of the brain dies or become seriously injured because the brain cells do not receive oxygen and they eventually die. People’s lifestyle may also impact seriously on their health and increase the possibility of having a stroke. Some of the risk that can severely increase the cause of stroke would be high blood pressure, heart disease, diabetes, cigarette smoking, as well as strokes that
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
People often know of strokes or someone affected by a stroke, but not always what constitutes a stroke. A stroke occurs when blood flow to the brain is interrupted or reduced due to a blockage or rupture of a blood vessel or artery that supplies blood to the brain. The interruption of blood flow deprives the brain of necessary nutrients and oxygen supplies, killing surrounding cells in the brain.

The bleeding of the brain also causes increased pressure on the brain and it presses against the skull. Symptoms of a hemorrhagic stroke vary upon the amount of blood tissues affected and the location of the bleeding. A transient ischemic attack only lasts for a few hours of the day or a day and it doesn't cause permanent brain damage like an ischemic stroke would. (TIA) transient ischemic attack is not considered to be a stroke, it is referred to as a warning signal before having a stroke. Ask yourself how does a stroke change a person's everyday life drastically? People who suffer from strokes have to live with a mental or physical disability that causes them to be limited.
So, what is actually happening when a stroke occurs? A stroke occurs blood flow to the brain is either impeded or significantly reduced. When this happens, the brain cells are starved of the essential oxygen and nutrients they need and begin to die. There are three different kinds of strokes. They are ischemic, hemorrhagic,

The World Health Organisation (2013) explains that an Ischaemic stroke occurs as a result of a blood vessel becoming blocked by a clot, reducing the supply of oxygen to the brain and, therefore, damaging tissue. The rationale for selecting Mary for this discussion is; the author wishes to expand her evidenced based knowledge of stroke since it is the principal cause of disability and the third leading cause of mortality within the Scottish population (Scottish Intercollegiate Guidelines Network (SIGN), 2008) and, therefore, a national priority. In response to this priority, the Scottish Government (2009) produced their ‘Better Heart Disease and Stroke Care Action Plan’. Additionally, they have introduced a HEAT target to ensure 90% of stroke patients get transferred to a specialised stroke unit on the day of admission to hospital (Scottish Government, 2012).
It is caused by clot that blocks blood vessels from supplying blood to the brain through cerebrovascular events. If there is no blood in the brain, then there is no oxygen or nutrients because it is blood that supplies it to the brain. This can cause permanent brain damage which can cause inflammation. Fasting has there been known to be effective and efficient against stroke because it increases cognitive functioning and health of the brain. In addition, fasting has been known to increase neuro-protective proteins and reduction in inflammatory substance known as cytokines. This is critical reducing the chances of damaging the brain that can cause
Your emotional health may change after a stroke. You may have depression, fear, anxiety, anger, sadness, and other feelings. Some of these changes happen because a stroke can damage your brain and nervous system. You may also have these feelings because coping with a stroke can be challenging.
The nature and extent of damage depends on the size and location of the affected blood vessels. b) Like all organs, the brain needs the oxygen and nutrients provided by blood to function properly. If the supply of blood is restricted or stopped, brain cells begin to die. This can lead to brain injury, disability, and possibly death. There are two main causes of strokes: ischaemic – where the blood supply is stopped due to a blood clot (this accounts for 85% of all cases) haemorrhagic – where a weakened blood vessel supplying the brain bursts.
Stroke is a commonly known disease that is often fatal. This cellular disease occurs when blood flow to the brain is interrupted by either a blood clot halting the progress of blood cells in an artery, called an Ischemic stroke, or a blood vessel in the brain bursting or leaking causing internal bleeding in the brain, called a hemorrhagic stroke. When this happens, brain cells are deprived of oxygen and nutrients because the blood cells carrying these essential things are stopped, causing them to die. When the cells in the brain die, sensation or movement in a limb might be cut off and may limit an organism’s abilities. A person with stroke is affected depending on where in the brain the stroke occurs. In other words, symptoms of a stroke
Stroke is a serious medical condition that affects people of all ages specifically older adults. People suffer from a stroke when there is decreased blood flow to the brain. Blood supply decreases due to a blockage or a rupture of a blood vessel which then leads to brain tissues dying. The two types of stroke are ischemic stroke and hemorrhagic stroke. An ischemic stroke is caused by a blood clot blocking the artery that brings oxygenated blood to the brain. On the other hand, a hemorrhagic stroke is when an artery in the brain leaks or ruptures (“About Stroke,” 2013). According to the Centers for Disease Control and Prevention (CDC), “Stroke is the fourth leading cause of death in the United States and is a major cause of adult disability” (“About Stroke,” 2013). Stroke causes a number of disabilities and also leads to decreased mobility in over half of the victims that are 65 and older. The CDC lists several risk factors of stroke such as heredity, age, gender and ethnicity as well as medical conditions such as high blood pressure, high cholesterol, diabetes and excessive weight gain that in...
Cerebrovascular Accident: The medical term for a stroke. A Stroke occurs when blood clots and forms blockages to an artery or blood vessel breaks, disturbing blood flow to an area of the brain. With either of these things the cells of your brain begin to die and brain damage occurs. When this happens the abilities controlled by that area of the brain are ceased, this includes but not limited to; Speech, Movement and even Memory. The effects depend on where the stroke occurs and how much of the brain is damaged. Someone who experiences a small stroke may only have minor problems such as weakness of a ligament. For those who experience larger attacks may become paralyzed on that one side or lose the ability to speak. Recovery from strokes is possible However, more than 2/3rds of stroke survivors will have some type of permanent disability.
