Due to the recent statistics, lung cancer has been known to be increasing twice as much in women than in men. Staying away from tobacco is the most important thing any of us can do to avoid getting lung cancer.There have been many cases of lung cancer as thousands of people are dying annually. Lung cancer would rank among the top 10 fatal cancers in Canada, since many people fail to realize the importance of maintaining a healthy body, most specifically lungs. Lungs are one of the key organs in our body. Located in the chest cavity, a lung is present on both the left and right side which are further made up of sections called lobes. The lung, due to its spongy and soft physical feature, the ribcage is responsible of framing and of protecting the lungs. The lungs are further developed into the bronchus, bronchioles and alveoli. The purpose of them are to bring oxygen (abbreviated O2), into the body and to then to remove carbon dioxide (abbreviated CO2) for the body. Oxygen is a gas that provides energy to us, while carbon dioxide is known as the waste product. Breathing is a part of life, and lungs are one of the main organs that help make the process of exhalation and inhalation possible .This occurs when the …show more content…

When this occurs, the lungs can’t release oxygen in the body . In return , other organs don't get enough oxygen-rich blood to function. Respiratory failure can also be developed if your lungs can’t remove carbon dioxide from your blood.Causing your body not to function how it usually does .Also when the lungs don't work your blood loses oxygen and starts to build up an excess of waste carbon dioxide. Muscles and other tissue can survive quite a long period without oxygen, but the brain cannot. Shortage of oxygen to the brain will can lead to

Bronchioles constrict from the increased pressure in the lungs from exhalation. Inhalation is easier because it relieves the pressure.

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.

Gases exchange by diffusion across the respiratory membrane. Oxygen diffuses into the blood and carbon dioxide diffuses from the blood into the lungs. alveoli Diaphragm When breathing in, the diaphragm contracts causing the thoracic cavity volume to increase, which makes air rush into the lungs. When breathing out, the diaphragm relaxes decreasing the volume of the thoracic cavity pushing the air out. This is an important part of respiration during exercise (O2 touch) as more air is needed in the body and carbon dioxide needs to be breathed out.

The concepts that are directly related to impaired gas exchange are: acid- base balance, perfusion, mobility, growth/development and anxiety. All these concepts were an issue when the patient first presented into the hospital; once the asthma attack was resolved and respiratory status because within normal limits these concepts resolved themselves as well. Acid-base balance is effected because the patient is breathing so fast and the body is not being able to exchange gasses affectively so there is a higher concentration of carbon dioxide in the blood than oxygen which illustrates as respiratory acidosis. Since there is decrease of oxygen in the blood the cells are not being perfused with adequate oxygen and then signs and symptoms of poor perfusion starts to be expressed. Then since the body is not being perfused well the cells and tissues do not have enough ATP to energize the cells which results in mobility issues.

An iron lung is a tank respirator with vacuum pumps pressurized to pull air in and out of the lungs. The iron lung saved lives, but it was a terrible reminder of what polio could do to you and its effects. As you can see, polio’s effects were devastating and you can also conclude why people feared polio.

The body’s gas exchange law of diffusion is where you will see the blood, cardiovascular system, muscular system, and nervous system work together to contribute and support human respiration. During the external respiration the pulmonary system is used to carry oxygen into the blood and remove carbon dioxide in the lungs controlled by the medulla. The internal respiration will use the systemic capillaries to carry the blood carbon dioxide, and remove oxygen from the tissue’s cell into the lungs, and this will happen with the blood. Furthermore, when an individual breathes there is a rhythm, and it comes from the breathing control center which is called the medulla (the pacemaker), and the pons.

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

It is connected to the upper part of the trachea and pharynx. It is formed by nine cartilages and eight muscles. Besides the larynx the trachea is also part of the system. The trachea is branch like tubes that carry oxygen to each individual body cell. It also transmit air from the larynx to the bronchioles.

Hypoxia: is the lack of adequate oxygen but hypoxic injury is due to low blood supply, which impacts the heart muscle (Huether & McCance, 2012, p. 63-65 ). After the cessation of blood supply to the heart muscle, the contraction stops due to decline in mitochondrial phosphorylation. This leads to low ATP production, which causes an increase in anaerobic metabolism, producing ATP from glycogen. Even when that is used up, the sodium and potassium pump on the plasma membrane and the sodium-calcium exchange fail to function. All of this causes cellular swelling and also lead to vacuolation, formation of vacuoles.

The medical world in the present day is much more advanced than it was just a few years ago. There are new medical breakthroughs as well as new diseases discovered every day. But, what we all have known for years is the tobacco is not good for the body and causes cancer. According to cancer.org, lung cancer is the leading cause of death by cancer in the United States and about 71 percent of Americans who have been diagnosed with lung cancer die from their cancer.

These airways divide like branches of a tree and get smaller and smaller until they reach the end of the line. At the end of the smallest airways are the alveoli tiny sacs deep in the lungs. That 's where your lungs take oxygen out of the air and move it into your blood — an important step because every part of

Exhaling is difficult and requires more time than normal. Other symptoms include a persistent, dry cough with small amounts of mucus due to the inability to cough it up. Physically, the shape of a person’s chest becomes barrel shaped due to the air trapping. Their chest and back appears rounded and the diameter of their chest is enlarged. The chest becomes rigid and fixed and the lungs are always

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).

Worldwide, tobacco use causes about 90% of lung cancer deaths, 30% of all cancers, 20-25% of coronary heart diseases and stroke deaths, and more than 80% of chronic bronchitis and emphysema”. (Jordan 1). Secondly not only does it affect smokers but even people who don 't even partake in the activity of smoking cigarettes. Second hand smoke is a serious issue and can cause cancer almost easy as being an actual smoker can.
