Cari's Story

process that Cari’s respiratory system is using to clear her lungs by coughing? The cough reflex is a deep and long inhalation that is followed by the closing the glottis, this causes a strong exhalation that will push the glottis open and sends the air through the respiratory passage. The coughing occurs when a foreign body is in the larynx, trachea or the epiglottis. Cari is coughing because the mucous and fluid buildup in her lungs and her body is to get rid of it. Which structures found in...

airflow in the lungs. The most common kinds of COPD include: Emphysema and Chronic bronchitis and other diseases. Emphysema can cause damage to the alveoli that cannot be cured; this is the tiny air sacs of the lungs where oxygen is put into your blood. With emphysema your lungs become less able to take in good air and get rid of carbon dioxide. Chronic bronchitis occurs when the airways in the lungs become swollen; this causes more mucus than normal to be made in the lungs. The swelling...

Blood Flow Unit 4

femoral vein to lower lobe of the right lung via the pulmonary artery. If blood did not flow through the body we as humans could not function the way we currently do. Oxygenated blood is carried through the body by veins and arteries and this is what feeds the body so it can function (Thibodeau, Patton, 2008.). Oxygenated blood is carried through the body by veins and arteries. The path blood take from the right femoral vein to lower lobe of the right lung via the pulmonary artery is as follows;...

Respiratory System

those which are concerned with the passage of the air to and from the lungs. The latter are, of course, mot important of all. The passage is also called respiratory tract. For the sake of convenience, the respiratory tract can be divided into upper and lower parts. The upper part extends from the external nostrils (external openings of nose) to the vocal sac present in the neck. The lower part extends from the vocal sac to the lungs. The nose has a passage called nasal passage which is lined by ciliated...

Chronic Obstructive Pulmonary Disease

COPD which is Chronic Obstructive Pulmonary Disease is known as a condition that progressively makes it harder to breathe because the airflow into and out of the lungs is reduced. This usually occurs because the airways and air sacs lose their elastic quality, the walls between the air sacs are destroyed, the walls of the airways become swollen, or if the airways are clogged because they made more mucus than usual. Three main conditions of this disease are emphysema, chronic obstructive bronchitis...

pulmonary arteries into the lungs. By having high blood pressure in the pulmonary arteries, this puts pressure on the right ventricle leading to a failure in pumping the blood effectively to the lungs to pick up oxygen because the ventricle has become too stretched and dilated ("COPD and Heart Failure ", n.d.). Due to the weak pumping of the heart’s muscle, blood will back up in the blood vessels and fluid may leak throughout the tissues in the body and around the lungs (ANRP, Thompson, & Thompson...

which is the trachea. 3. Describe the structure and location of the trachea. Explain its function in relation to respiration. The trachea is lined by cartilage and divided into two branches, called the bronchi, which enter the left and right lungs. It is composed with pseudostratified columnar epithelium. The trachea is the windpipe which conditions – warms, moistens, and removes particles – of the air inhaled. 4. Describe the structure and function of the cricoid cartilage. The cricoid...

Anatomy and Physiology of Respiratory System

so that food will not be directed to the lower respiratory passages. The food will be then routed to the esophagus and in cases where it enters the larynx, a cough reflex is triggered to expel the substance and prevent it from continuing into the lungs. This protective reflex does not work when a person is unconscious that is why it is not allowed to offer or administer fluids to an unconscious client. Vocal folds – a pair of folds which is also called the true vocal cords that vibrate when air...

passageways (bronchi and bronchioles), and lungs. The Nose or Nasal Cavity As air passes through the nasal cavities it is warmed and humidified, so that air that reaches the lungs is warmed and moist. The Nasal airways are lined with cilia and kept moist by mucous secretions. The moisture in the nose helps to heat the air, increasing the amount of water vapour the air entering the lungs contains. This helps to keep the air entering the nose from drying out the lungs and other parts of our respiratory system...

Asthma And Emphysema Comparison

Asthma and emphysema are both known as obstructive lung diseases. Obstructive lung disease occurs when the airway is obstructed and is worse with expiration. For example, more force is required to exhale and emptying the lungs is slowed (Huether & McCance, 2012, p. 689). The most common type of obstructive lung diseases are asthma, chronic bronchitis, and emphysema. Although, they are categorized as obstructive lung disease they have many similarities in that they have similar symptoms such as...
