Asthma
Breathing is a vital process for every human. Normal breathing is practically effortless for most people, but those with asthma face a great challenge. During an asthma attack, breathing is hampered, making it difficult or even impossible for air to flow through the lungs. Asthma is an increasingly common problem, and has become the most common chronic childhood disease. At least 17 million Americans suffer from it(1), and although it can be fatal, it is usually not that severe(4). There is no cure for asthma, but with proper care, it can usually be controlled.
As someone with Exercise Induced Asthma, I have personal experience with the topic. I have experienced most of the symptoms described in my research, tried many of the medicines, and have my asthma under control. This essay will first discuss the normal function of the lungs, and then proceed to explain how this is effected by asthma. The causes of the disease and the ways of controlling it will follow.
Normal breathing is controlled by the lungs and the chest cavity. Airways are tubes with muscle that contracts and relaxes wrapped around them, and this accounts for the motion of the chest that is associated with breathing. The diaphragm, which is located underneath the rib cage, along with the intercostal muscles, or those in between the ribs, control the movement of the chest cavity(6). When these muscles contract, the chest expands, which lowers the pressure inside the lungs. Since air moves naturally from high to low pressure, the lungs are automatically inflated. In order to exhale, the diaphragm and the intercostal muscles relax, causing the chest cavity to become smaller. The decrease in volume causes the pressure in the lungs to go...

The contraction of the inspiratory muscles increases the volume of the thoracic cavity causing the pressure within the alveoli to decrease and air to flow into the alveoli. During resting inspiration, the diaphragm, the external intercostals and the parasternal intercostals contract to stimulate inspiration. During forced inspiration the scalene and the sternocleidomastoid muscles contract to further expand the thoracic cavity. The pectoralis minor muscles also play a minor role in forced inspiration. During quiet breathing, relaxation of these muscles causes the volume of the thoracic cavity to decrease, resulting in expiration. During a forced expiration, the compression of the chest cavity is increased by contraction of the internal intercostal muscles and various abdominal
Aims: To implement a multi-pronged strategy that (1) educates parents, students, and school staff about asthma and its management, (2) establishes comprehensive asthma screening programs, (3) develops affordable and long-term management strategies for students with asthma, and (4) increases the rigor of school inspections with regards to air quality and other common asthma triggers.
•While exercising your lungs tries to increase the intake of oxygen as well as release the carbon dioxide.
When you breathe in, air containing carbon dioxide (CO2) and oxygen (O2) it moves down your trachea; a tunnel containing cartilage and smooth tissue. Air then travels through two hollow tubes called bronchi; narrow branches lined with smooth muscle, mucosal and ringed cartilage to support the structure. The bronchi divide out into smaller tunnels called bronchioles; are small branches 0.5-1mm, lined with muscular walls to help dilate and constrict the airway. At the end of the bronchioles are little air sacs called alveoli; which assist in gas exchange of O2 and CO2. (Eldridge, 2016) Towards the end of alveoli are small blood vessel capillaries. O2 is moved through the blood stream through theses small blood vessels (capillaries) at the end of the alveoli and the CO2 is then exhaled. (RolandMedically,
Some people only experience asthma symptoms during physical activity. A person who suffers from exercise-induced asthma does not have to limit his/her athletic goals.
In The Scarlet Letter, Nathaniel Hawthorne utilizes imagery to convey that Dimmesdale can represent Puritan Society rather than the round character that can be seen on the surface level. This is seen through the imagery and symbolism of hypocrisy, Dimmesdale as a Christ figure, and the scarlet letter.

Maggie: A Girl of the Streets, is a realist outlook on the gritty underside of Industrialized America. It is a story that doesn't withhold the dirt and grime that came with living in highly populated impoverished areas. The young Stephen Crane does a very good job portraying the destruction of a young, beautiful, and optimistic Maggie by forces outside of her own control. The rather dreary realism of the novel was a little unheard of at the time. Crane had to publish his book himself, as no publishers wanted to take the chance on a novel so negative about human nature. However, over time his story quickly cemented its roots as a fundamental column of American Realism Literature.
Imagine a young child competing with his or her fellow classmates during recess and immediately losing the ability to breathe normally. He or she stops in the middle of the competition and falls to the ground while holding his or her chest trying to find air. When you are young, being able to keep up with your peers during recess and sporting events is very important, however, having asthma restricts this. Asthma has a significant impact on childhood development and the diagnosis of asthma for children 18 years and younger has dramatically increased over the years. Asthma is known as a “chronic inflammation of the small and large airways” with “evident bronchial hyper-responsiveness, airflow obstruction, and in some patients, sub-basement fibrosis and over-secretion of mucus” (Toole, 2013). The constant recreation of the lung walls can even occur in young children and “lead to permanent lung damages and reduced lung function” (Toole, 2013). While one of the factors is genetics, many of the following can be prevented or managed. Obesity, exposure to secondhand smoke, and hospitalization with pneumonia in the early years of life have all been suggested to increase children’s risk of developing asthma.
Secondly, severe asthma can be life-threatening. Suffering from asthma can be frightening to experience and people often feel scared and anxious. The fear and scare can also lead to breathlessness and so mak...
Most of you may not think of asthma as a killer disease, yet more that 5,000 Americans die of asthma each year. According to the Mayo Clinic web page, asthma also accounts for more that 400,000 hospital discharges annually. As the number of people with asthma increases, the more likely you are to come in contact with a person who has the disease. As far as I can remember, I have had asthma my whole life. My mother and one of my sisters also have asthma, so I have a first hand experience with it. This morning, I will discuss some interesting facts about asthma, I will specifically focus on what it is, warning signs, symptoms, causes, and the treatments that are used.
Particularly, two members within my group began to emerge as leaders due to their knowledge, skills, as well as experience working with our chosen population. Although I always view them as ‘experts’ in this topic, our group became less focused on our goals and more concerned about the ‘power struggle’ between our two leaders, before we could reach any consensus. Essentially, our group had two authoritarians butting heads and trying to take lead throughout the beginning of the group process. Thus, the other members or ‘followers’ contribution, like mine, seem to not matter unless they adhered to either leaders’ opinions without question. According to Stringer (2014), “Leadership… Is defined according to its function of facilitating organizational and operational processes, rather than defining and controlling them” (p. 31). The researcher further states that active participation is the key to encourage and motivate group members to invest their time and energy to shape the quality of the group's production. Therefore, our group needed to find ways for all members to have a chance to participate fully and apply their individual strengths, in order to enhance our group’s
In 1888 Stephen entered the Claverack College military school. Stephen distinguished himself on the drill and baseball field, but not in academics. Without graduating, Stephen transferred to Lafayette University and later Syracuse. While living in his fraternity, Delta Upsilon, Crane started his first major novel. He would eventually flunk out of college. At the age of 20 Crane moved back to Asbury Park to work as a reporter for the New York Tribune with his brother. Crane’s first experiences with his literary ideals started when he attended Hamlin Garland’s lectures on realism. Crane was deeply influenced by Garland’s guidance and tutelage. In 1891 Crane’s mother died. He then moved to Sullivan County, New York where another brother of his was studying law. Crane’s first magazine appearance was a set of poems called “Sullivan County Sketches,” printed in the Tribune and Cosmopolitan. Crane frequented the slums of New York City, haunting the labyrinth of streets in sear...
Asthma incidence has risen steadily over the past 20 years and directly impacts the lives of millions (U.S.EPA, 2013). Currently, there are about 23 million people, including 7 million children affected by asthma (U.S.EPA, 2014). The Centers for Disease Control indicate an asthma prevalence rate of 8.4% in the United States (CDC, 2011). Additionally, asthma accounts for approximately 500,000 hospitalizations annually. It is also the third highest cause of hospitalization among children under 15. As asthma incidence continue to rise, the American Academy of Allergy, Asthma and Immunology (AAAAI) estimate the number of people with asthma to grow more than 100 million by 2025 (U.S.EPA, 2014).
