Essays on Exhalation

There are both molecular and physiological events that support the statement that the concentration level of FENO is a measure of the degree of asthma in an individual. In the molecular sense, the measure of FENO level in exhaled air is a measure of the intensity of Asthma, and depending on the molecular cut points stated it could be concluded that certain Asthma is reasonable or outrageous. According to Ricciardolo, et al., (2010), there is an evidential fact relating the concentration of FENO to the asthma level in children. Thus, the use of the specific measure of the molecular ...

Introduction

This paper aims at evaluating concepts of alteration in homeostatic state, secondary to temporal variables. It analyses the case study of Brad, a 45-year old coal cutter who has held the job for 25 years. Brad is experiencing a chronic cough due to prolonged exposure to coal. Importantly, he has not been attending yearly checkups because he fears that his lung is “black.” The disease leads to fibrosis, reduced diffusing ability, and dilation of the small airways. In the final stage, the airways, alveoli, and pulmonary capillaries become damaged.

How the disease described in the case study creates incongruous between ventilation and perfusion

Chronic lung disease may induce mismatch in ventilation and perfusion ...

The cardiovascular system consists of the heart and blood vessels that get bifurcated further into veins, capillaries, and arteries. Lungs and airways make the most of the respiratory system; these, coupled with other structures help in the inhalation and exhalation process. Muscles are the other part of the system that helps the lungs to expand and contract in sync with inhalation and exhalation. Absorption starts in the body after the food is broken down into its building blocks. The process of absorption starts in the abdomen with the direct consumption of simple substances( e.g. water and alcohol) into the ...

The cardiovascular and respiratory systems are largely responsible for the transportation of oxygen and carbon dioxide through the body. Respiration consists of both inspiration and expiration. These actions are the methods by which essential oxygen is exchanged with harmful carbon dioxide. While oxygen is brought into the lungs during inhalation to be processed throughout the body, carbon dioxide is brought during exhalation to be removed from the system entirely. Once the oxygen has reached the lungs it is taken up by the bloodstream in order to be distributed to the various cells that require a constant exchange of nutrients ...

Question 1. Insect-eating birds will decrease in number since their source of food has been reduced. The birds may also migrate to warmer areas during this period.

Question 2.

The habitat is the specific place where the organism lives e.g. a fish’s habitat is water. On the other hand, niche is the position and the role played by the organism in an ecosystem. It includes how the organism obtain food and shelter, the mode of survival, and the mode of reproduction (Sutton & Anderson, 2009, p. 46). For instance, a lion’s niche in the ecosystem is that of a predator.Question ...

Introduction

Approximately 2.5 million individuals in the United States contract pneumonia annually, and 55,000 of those individuals die as a result. In fact, pneumonia was the eighth prominent cause of morbidity and is the number one communicable disease in the United States. Pneumonia is the leading deadly hospital-contracted disease and contributes to a sizable amount of deaths in unindustrialized countries as well. It is a grave illness that can impact individuals in all age groups, but it is especially serious in adolescents, the elderly population, and in people with fundamental medical issues such as ischemia, low blood sugar, and ...

Respiratory system

The respiratory system comprises of the nostrils, the nasal cavity, the nasopharnyx, the bronchi, the bronchioles, the trachea and the alveoli. It can be further divided into two: the upper respiratory tract and the lower respiratory tract. The upper respiratory tract is made up of the nasal passages, pharynx and the larynx. The lower respiratory tract is made up of the trachea, the primary bronchi and lungs. The major function of the respiratory system is the exchange of gases within the body specifically it delivers oxygen to the blood and removes carbon dioxide from the blood. The gaseous ...
