Respiratory rate

The respiratory system is the major system of organs that facilitates the process of respiration. This system controls a gas exchange which involves the distribution of oxygen throughout the body and the removal of carbon dioxide from the body as waste. In other words, it plays a crucial role along with the circulatory system during the action of breathing and maintains a constant supply of oxygen into the bloodstream. In turn, the respiratory system provides trillions of cells with energy from…

Hyaloid canal: The hyaloid canal is a small, transparent tunnel that traces its path through the vitreous body of the eye, spanning the optic nerve disc to the lens. In an adult person, the hyaloid canal carries lymph to help change the volume of the lens. When the lens expands, the hyaloid canal compresses, so that the eye’s internal pressure and volume remain constant (Merriam-Webster). Optic nerve: A part of the central nervous system, the optic nerve connects the eye to the brain, carrying…

Air pollution is the primary reason of why many adults and children suffer from several respiratory illnesses. The outdoor air pollution is not only man-made but nature has a role in it. Millions of people die or are diagnosed with diseases that could be acute or chronic. There are ways to save lives with simple steps that could be impactful. It could be complicated because of all the political and economic value tied into it, but there is always a way to make change possible.…

Introduction I chose to write about the most versatile animal that I can think of, the coyote! The coyote is a native to my original home, Wisconsin and to my current home, Colorado! The coyote is a mammal, just like us! This being said, they are many similarities in the make up of this animal! Coyote They coyote comes from the classification of eukaryote. From the “root” of the branch, comes both animals and plants. Animals and plants are sister taxa, meaning that they branch off from eukaryote…

1. Anatomy of the trachea and bronchi. The trachea (Fig.1) is a cartilaginous and membranous tube, extending from the lower part of the larynx, on a level with the sixth cervical vertebra, to the upper border of the fifth thoracic vertebra, where it divides into two main bronchi, one for each lung. The trachea is nearly but not quite cylindrical, being flattened posteriorly; it measures about 11 cm. in length; its diameter, from side to side, is from 2 to 2.5 cm., being always greater in…

Measurement of diffusing capacity (DLCO) One of the most clinically lung function test is diffusing capacity of the lung for carbon monoxide (DLCO). In addition it's known as the transfer factor of the lung for CO (TLCO). This test measures the capability of the lungs to transmit gas from inhaled air to the pulmonary capillaries in the red blood cells and to determine the efficiency of the lungs to exchange gases. The indication of using this test is to recognize the cause of hypoxemia and…

I am writing today about a noncommunicable disease that affects 26 million Americans. The mortality rate of this disease is approximately 4,000 per year and causes almost 14 million visits to the Doctors office and 1.75 million emergency room visits. This disease is called asthma, also known to many as reactive airway disease. The reason I chose this particular illness is because of the impact it has had on my brother’s life since he was diagnosed at the age of 3. Asthma is a chronic…

Bronchitis is an inflammation of the bronchial tubes, or bronchi, that bring air into the lungs. Inflammation is a chemical reaction in the body that produces redness, swelling, and pain. When the cells lining the bronchi are irritated, the tiny hairs (cilia) that normally trap and eliminate things from the outside stop working. Formation of material associated with irritation swelling also increases; causing the passages to become clogged. The same viruses that cause colds, often cause acute…

Respiratory Syncytial Virus – RSV Anatomical & Physiological Influences Causes RSV more frequently effects infants but can affect adults. Infants who have had RSV have an increase frequency of wheezing. Air enters the respiratory tract through the nose or mouth and then either enters the nasopharynx, or oropharynx respectively. Continuing through the laryngopharynx to trachea, which divides at the carina to form the left and right main bronchus. In each lung the bronchus divide into the…

Allergic Rhinitis/ Hay Fever I believe allergic rhinitis (AR), commonly known as “hay fever,” best fits the symptoms presented in this case study as this condition is becoming an increasing common issue in the U.S. AR is the inflammation of the nasal membranes induced after exposure to allergens via IgE-mediated hypersensitivity reactions (Min, 2010). This condition is characterized by symptoms of watery rhinorrhea, nasal obstruction, nasal itching and sneezing and is also frequently…
