    Atrophy Case Study

    During apoptosis, cell size decreases and the nucleus undergoes fragmentation while the plasma membrane and cellular contents remain intact. Necrosis is unregulated while apoptosis may be induced to get rid of unwanted cells. Necrosis can affect entire organs including the kidneys, heart, pancreas, adrenal glands, and many more. Necrosis may cause dead brain tissue, fat, lower leg tissue, and extremities. Although apoptosis can also occur in normal tissue, it is often beneficial, such as involution of the lactating breast after weaning. Other times apoptosis occurs is after severe injury (to remove cells that cannot be repaired), to remove misfolded proteins, and to remove cells that are infected. Apoptosis can be excessive, which is known as dysregulated apoptosis, and can increase risk of…

    Black Death

    The Black Plague is one of the deadliest pandemics in human history. The Plague Struck and killed with terrible speed leaving the few who still remained alive in shock and utter confusion. People became desperate and turned to religion for hope and an explanation for this deadly event. Despite the Black Plague Striking World Wide, the Christian and Muslim reactions where quite different. These disparate reactions grew as the mortality rate due to the Black Death grew. The Background of the Black Plague is as intriguing as the variant reactions themselves and vital for fully understanding the differences in the response these two religions had towards the Black Plague. The Christian reaction was to blame the Jews and was fueled by the fear. On the Contrary the Muslims reacted in a more religious manner than blaming. The cause of all of this of course all come from general trade routes near the Mediterranean that spread the plague like a wild fire.…

    Black Death

    The Black Death was a plague that devastated Europe during the 14th and 15th Century. Before the plague, Europe was in the Late Middle Ages, a time of both development and problems. Some of these problems were causes of the plague. The Black Death has changed Europe economically by causing people to pay for religious services, making nobles pay higher wages to peasants and serfs and helping peasants gain money. Socially, the Black Death caused the downfall of feudalism and created discrimination amongst certain groups of people. Overall, the Black Death was an event that altered Europe.…

    Cell injury and cell death

    The most common form of cell injury is hypoxic injury, or hypoxia, the deficiency of adequate oxygen. Ischemia is the most common cause of tissue hypoxia and is caused from a decrease in blood flow. Hypoxia can also be caused by a reduced amount of oxygen in the air, loss of hemoglobin, diseases of the respiratory and cardiovascular systems, and decreased production of red blood cells. Cardiac ischemia is one of the most recognizable forms of hypoxic injury and is caused by a blockage in the coronary arteries of the heart. Once the blood flow to heart tissue decreases or stops completely, the heart tissue is damaged and can lead to further complications including a myocardial infarction.…

    Black Death

    Today, African Americans are literally dropping dead physically and mentally. Males to be even more specific, We are not only killing each other but we are falling into this system the government has set up for us. It’s what I’d like to call “Black Death”. Black Death is not just the killing of African Americans but the incarceration of us as well. We are close to 1 million of the total 2.3 million incarcerated populations. We are incarcerated at six times the rate of whites. It amazes me just a little that African Americans were 58 percent of all prisoners in 2008, even though African Americans at that time only made up approximately one quarter of the US population. According to “Unlocking America”, if blacks were incarcerated at the same rates of whites, today's prison populations would drop tremendously, approximately 50 percent. One in six black men had been incarcerated as of 2001. According to “Unlocking America” this means that if this continues, one in three black males born today can expect to spend time in prison during his lifetime. It’s a shame studies can show and give factual statements that black males unborn could possibly end up in jail. Nationwide, African Americans represent 26 percent of juvenile arrests, 44 percent of youth who are detained, 46 percent of the youth who are judicially waived to criminal court, and 58 percent of the youth admitted to state prisons center on Juvenile and Criminal Justice. So not only is this system of “Black Death” affecting adults, they’re corrupting our young African Americans as well. What I mean by corruption is the public school system. Not only is the government giving our young leaders of the future the bare minimum and just passing them on, they’re feeding them lies. Public school districts are failing to educate students, if students lack education they will not be prepared for the world which will cause them to fall into these stereo types of not being able to success. Education weekly’s studies show…

    Comparison of Necrosis and Apoptosis

    Necrosis is an uncontrolled process in which there is a complete breakdown of cellular homeostatis with a large unco-ordinates breakdown of all cellular constituents. Necrosis can occur due to many factors such as an infection or failure of blood supply (ischemia). Examples of necrosis can includes Fat necrosis (seen in patients with breast cancer), Caseous necrosis and coagulation necrosis (common in TB patients). On the other hand, Apoptosis is a controlled process, which is often referred to as 'programmed cell death' and involves the cell undergoing a sequence of events to eliminate harmful cells without releasing harmful substances to the area. Apoptosis can undergo 2 pathways, the intrinsic and extrinsic pathway.…
