orotracheal intubation where‚ with the assistance of a laryngoscope‚ an endotracheal tube is passed through the mouth‚ larynx‚ and vocal cords‚ into the trachea. A bulb is then inflated near the distal tip of the tube to help secure it in place and protect the airway from blood‚ vomit‚ and secretions. Another possibility is nasotracheal intubation where a tube is passed through the nose‚ larynx‚ vocal

low concentration. 4. Explain the functions of the following parts of the respiratory system?? Larynx: The larynx is a passageway for air between the pharynx and trachea. It filters bacteria‚ helps in voice production and warms and moistens the air. Cartilage Rings: To prevent the trachea from collapsing inwards when there is no air. Trachea: The trachea is a passageway for air between the larynx and the bronchi.

Before delving into the computational methods of reconstructing the respiratory mod- els‚ we first discuss the respiratory system from a functional point of view. In addition‚ descriptions‚ locations‚ geometry‚ and naming conventions for the anatomical parts are discussed in order to establish a basis for decision-making when reconstructing the model. This chapter provides the fundamentals of the anatomy and physiology of the respiratory system and may be skipped if the reader has an established

Cari’s Story How could an infection in Cari’s nasal passages and pharynx spread into her sinuses? An infection will spread because the pharynx‚ larynx and sinuses are all connected‚ so the infection is going to spread to the sinuses and the surrounding areas. What is the cough reflex? Describe the 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

Pharynx * Travels down the Larynx * Reaches the lungs and goes through the Bronchi * Through the Bronchioles * Then reach’s the Alveoli * The Oxygen then leaves the lungs and is transported around the body via blood vessels * Deoxygenated blood carries the Carbon Dioxide back to the lungs * The deoxygenated air then retraces its steps * Back to the Alveoli * To the Bronchioles * Through the Bronchi * Through the Larynx and Pharynx * Then finally

Role of energy in the body There are six main forms of energy- Chemicals Heat Electrical Light Nuclear Sound Energy can be measured or expressed by joules or unites of hear (kilocalorie). 1 kilocalorie= 4.184 kilojoules. Sources of energy- Protein 1g= 4 kcal Carbohydrate 1g= 4 kcal Fats 1g= 9 kcal In our bodies we need energy we need energy for everything we do‚ move our muscles‚ talk etc. Without energy we wouldn’t be able to do anything‚ energy is needed for our bodies to function

The following are examples of frequently missed questions from the unit exams. The questions are similar in theme to the ones missed however were taken from blackboard and are not exactly worded like the exam questions. They are meant to act as a study guide only. Please do not have the misconception that these questions will be the exact questions on the final. What you should do is to use these questions as a guide and to research not only why the answer is correct but also why the other answers
