Asthma is a common condition of the Respiratory system characterised by periods of muscle constriction or inflammation (swelling and excess mucous production) involving the bronchial tubes (airways) thus causing difficulty in breathing.
The Respiratory system has a major role in the function of breathing by exchanging gases throughout the body’s muscles and tissues and external environment. The respiratory system composes of several organs responsible for the process of breathing; these include the nose, mouth, trachea (windpipe) and the lungs. These major body parts are involved in, and responsible for, the process of respiration whereby oxygen is inhaled and carried throughout the body and the blood stream, while exchanging and eliminating carbon dioxide from the body through exhalation, thus allowing us to live. Other components of the Respiratory system include the larynx, pharynx, diaphragm and bronchial tubes.
During inhalation, the muscles in the chest wall begin to contract causing the diaphragm to move downwards expanding the size of the chest cavity, allowing oxygen to enter. Moreover, by expelling air from the body through exhalation this results in the process known as ventilation …show more content…

Asthma produces a contraction of the bronchial passages causing inflammation of their mucosa lining. As a result, the body responds by activating defence cells from the immune system which causes the airways to swell and the muscles surrounding the airways to contract resulting in the obstruction of airflow. Research suggests that there are 3 main impacts to why the airways become narrow. One reason was due to extra mucus (sticky fluid) building up and causing the airways to be blocked, another was due to muscles squeezing tight around the airways also known as ‘bronchoconstriction’, the last of the three impacts was the lining of the airways becomes red and inflamed

Mucus production might also increase (Porth, 2014, p. 973). The airways are ultimately obstructed, making expiratory flow difficult. 4. Why is Al’s AP chest diameter increased and how does this correspond to the PFTs?

How does this improve Mike’s asthma? - Albuterol is used to relax the muscles that are in the bronchioles to relieve breathing. It relaxes smooth muscle by decreasing the calcium ions. Calcium ions are necessary to produce muscle contraction. It improves Mike’s asthma because it is relaxing his smooth muscle, which allows for a clear pathway for airflow to help him breath

On attached paper On attached paper The bronchioles use elastic fibers instead of rings of cartilage; therefore, they are more likely to collapse. During an asthmatic episode, the airways are inflamed and are sensitive. The muscles around the airway tightens and causes less air to pass to the lungs.

The trading of gasses in the middle of air and blood happens cross the dividers of respiratory alveoli. Alveoli are microscopic flimsy walled air sacs that give a colossal surface zone to gas dispersion. The locale of the lungs where gas trade with the blood happens is known as the respiratory zone. The trachea, bronchi, and bronchioles that convey air to the respiratory zone include the leading zone. The thoracic cavity is constrained by the mid-section divider and diaphragm.

Understanding respiratory volumes, capacities, and measurements will help me perform my job as a medical assistant because they are significant being a medical assistant. First of all, when the patient is on the bed, I will measure the respiratory rate while he/she is at relaxation. In the next, I will observe the rise and fall of the victim 's chest and count the number of respirations for one full minute. Then, I will record the current time, respiratory rate and respiratory characteristics. Spirometry is used diagnose conditions that affect breathing such as asthma, pulmonary fibrosis, and cystic fibrosis.

Hyaline membranes help to the development of fibrosis and atelectasis (collapse) essential to decrease in gas exchange capability and lung dysfunction. These changes cause the lungs to become stiff, patient work hard to inspire. Hypoxemia and the stimulation of juxtacapillary receptors in the stiff lung parenchyma leading to increase respiratory rate and decrease in tidal volume. Breathing irregular increase carbon dioxide removal,

“You have the mind but you have not the body, and without the help of the body, the mind cannot go as far as it should. You must make your body. It is hard drudgery to make one’s body, but I know you will do it” Teddy got told. He liked to wrestle and box for exercise. Theodore’s father was a great asset to him, and he helped Teddy through complicated situations, asthma being one of them.

Asthma has a significant impact on society, affecting over 6 million children under the age of 18 in the United States alone. Reasonable ways to control this disease are medications such as inhalers and spirometry to test the strength of your lungs. There is a myriad factor from environmental constraints, physical and the one built by humans is noted as a major factor affecting the development of asthma. Indoor air pollution is the most common form of air pollution, along with first-hand and second-hand smoking. Air pollution is often greater in lower socioeconomic neighborhoods with mold and cockroach infestations and access to medical care.

From these questions that were given out by Dr. Frander, many students should have a great understanding what to expect to the mid-term exam. Dr. Frander really encouraged us to study because most of these questions are difficult. For instance, she gave us an example in a patient who has COPD/ emphysema. What we have concluded from this question what they are looking for the emphysema patients don’t have a problem of taking air in rather they have a problem of taking the air out. The main problem of the emphysema, they have a lot of mucus, and the alveoli which where the gas exchange takes is impaired.

It also helps provide oxygen to the body. External respirations is when you breathe in through your lungs and carbon dioxide exhaled out. Internal respirations is what you inhales goes from the lungs back to the heart. 4. Describe eight signs and/or symptoms of the respiratory system.

Heart, lungs and the Rest of You By: Olivia Abel 1.Explain how the blood flows throughout your lungs, heart and the rest of your body.   Heart: Your left and right side of your heart work together to pump blood to and throughout your body which is separated by muscular tissue called the septum. In the right side blood enters through two large vein which are the inferior and superior vena cava, emptying poor oxygen blood from the body to the right reticulum. When the left side enters from the pulmonary veins and empties oxygen rich blood from the lungs into the aorta going throughout the body.

Lung volume and lung capacity are two measurements of respiratory health and measured during pulmonary functions tests. It is show the physical condition of the lungs. Pulmonary ventilation, or breathing, is the process of air flowing into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation). Air flows because of pressure differences between the atmosphere and the gases inside

Pneumonia and asthma are two kinds of diseases that affect the airways in the lungs. Although both of them are different, they have some common denominators in the cause, symptoms, and the possibility of treating the inflammation at home. Both pneumonia and asthma make the air sacs in the lungs become tighten or blocked by an inflammation. For example, a person can obtain pneumonia or make asthma become worse after getting any upper respiratory infection such as flu or cold. Some symptoms of pneumonia and asthma are similar to each other such as chest pain, coughing, wheezing, and difficulty in breathing.

The heart may have the sinoatrial node (SA node) to trigger contraction, but in order for us to breath our nervous system has to signal for us to begin the process of ventilation (breathing). Our brain stem has three parts to it, but only the pons and medulla oblongata play a key role in breathing. The medulla helps set the respiratory rhythm by receiving and sending impulses to a bundle of neurons called the ventral respiratory group to the phrenic nerve to bring about contraction in the diaphragm and external intercostal muscles. All this only happens though due to the sensors of the chemoreceptors. The chemoreceptors located in the medulla and carotid and aortic bodies detect a rise in carbon dioxide (CO2).
