pointing dorsally. There are taste buds on the epiglottis. The image shows where the epiglottis can be found in the body. The pharynx is an organ found in vertebrates and invertebrates. In humans the pharynx is part of the digestive system and also of the conducting zone of the respiratory system. The conducting zone also includes the nose, larynx, trachea, bronchi, and bronchioles, and their function is to filter, warm, and moisten air and conduct it into the lungs. It makes up the part of the throat situated

Section 1 : Anatomy and Physiology The respiratory system, also known as the ventilatory system, is a series of organs found in the human body. The system’s primary function is performing respiration – inhaling oxygen from the environment and exhaling carbon dioxide out of the body (K.M Zimmermann, 2016). Oxygen acts as fuel – without it, the body would be unable to function. Carbon dioxide, the by-product of this process, is breathed out as it is toxic to the human body when it builds up (A.M Helminstine

Abstract Tracheostomy Care is essential for patients who are in respiratory distress. Nurses need to prevent complications and promote education to care for this device. Cleanliness of this device will keep the patient health from deteriorating, and ultimately prevent any infections that could possibly arise if the tracheotomy is not taken care of properly. The purpose of a tracheostomy may have a myriad of reasons. A couple of reasons to perform a tracheostomy may be due to a blocked airway, obstruction

Comparisons: The tracheal tubes of insects compared to that of the fish’s gills or the mammal’s lungs are structured in a way that makes the gaseous exchange function most efficiently. Each body cell in the insect is connected to a tracheole and the gases diffuse directly with the respiring cell, whereas in mammals and fish, the oxygen gas have to be diffused into the blood stream where it is then transported and diffused into the living cells (carbon dioxide is diffused out of the cell into the

he food passageway. Because natural selection cannot start from scratch, humans are stuck with the possibility that food will clog the opening to our lungs. The path of natural selection can even lead to a potentially fatal cul-de-sac, as in the case of the appendix, that vestige of a cavity that our ancestors employed in digestion. Because it no longer performs that function, and as it can kill when infected, the expectation might be that natural selection would have eliminated it. The reality is

Breathing is an automatic process that takes place in the respiratory system. Air enters and exits the respiratory structures through the process inhalation and exhalation. Air moves in and out of the lungs as a result of changes in pressure. Inhalation is achieved when the pressure inside the lungs is less than the pressure outside of the lungs. The diaphragm contracts pulling air into the lungs. When the pressure inside the lungs is less than the pressure outside the lungs, exhalation occurs allowing

larynx, trachea, bronchial tree, and lungs. The system served the main purpose of transporting air into the lungs, and flows from the top to bottom. Nose is a convex feature lays in between and under our eyes, structured with bones, muscles, and flexible tissues named cartilage; with long thin nasal bones supporting the nose structure. Nostrils on nose are pathways for air to enter, and there grows nostril hair to prevent large particles to enter. The empty space

According to Melinda (2014), the function of respiratory system is to supply oxygen into the body, by breathing in, and to remove carbon dioxide which is the waste, from the body, by breathing out. Franklin (2014), outlines that oxygen is most needed in the body, in order to live. This is because every cell in the body needs oxygen, in order to function properly. Also, oxygen is required in the blood in order to covert food into energy. Beside, Melinda (2014), clarifies that these movements are

respiratory system comprises of different organs used in respiration. Respiration involves inhalation and exchange of oxygen and carbondioxide between living organisms and the environment. The organs of respiration include; the nose, pharynx, larynx, trachea, 2 bronchi, bronchioles, 2 lungs and muscles of breathing (the intercostal muscles and the diaphragm). 5.1 Personal context Respiratory system assessment is the process of evaluating the functioning and condition of a patient’s respiratory system

Birds are a group of animal which consist of many species, all of which play various roles in several ecological niches. Birds are considered ‘biologically successful’ due in fact to the number of species present. Currently, there are approximately 10,000 species of birds, which is almost double the amount of species of mammals or amphibians. The differences which separate birds from mammals and make them more successful are the presence of large yolked eggs, which support the offspring until birth
