Florida University: Chapter 20-31| NUR 3125Med-Surg Exam 3 Chapter 20: Assessment of Respiratory Function Purpose of the respiratory system ● Deliver oxygen to the body, expels carbon dioxide from the body ○ Works with the circulatory system ● Upper respiratory system: warms and fills air ○ Nose: serves as passageway, filters impurities, humidifies and warms air ○ Sinuses and nasal passages ■ Paranasal sinuses: lines with mucosa and ciliated pseudostratified epithelium; s...

BIOD 151 ALL LAB EXAMS COMBINED 2022/2023 BIOD 151 ALL LAB EXAMS COMBINED 2022/2023 Lab 1 1. Susan Smith is a participant in an Anatomy and Physiology lab class. Susan walked into lab today carrying a bagged lunch that she brought to eat following class. She has long blonde hair that is not pulled back. Today in class, you are reviewing basic microscopy and you notice that Susan’s microscope is partially hanging off the edge of her lab bench. Given what you learne...

Volume of air in one quiet breath - tidal volume warms, humidifies, cleanses air; detects odor, voice amplification - the nose little horn looking cartilage in the larynx - corniculate cartilage the sum of the anatomical and pathological dead space - physiological dead space ______ and _______ insures air contacts mucus membranes - narrowness and turbulance this rotates the corniculate and arytenoid cartilages, changes the pitch of sound - deep intrinsic muscles (infrahyoid group)...

What are the two major categories of lower respiratory tract disorders. - ans --Chronic obstructive pulmonary disease (COPD) and restrictive pulmonary disease COPD is caused by airway obstruction which causes.... - ans --increased airway resistance of airflow to lung tissues. causes a decrease in total lung capacity as a result of fluid accumulation or loss of elasticity of the lung. - ans --Restrictive lung disease What is the definition of Asthma - ans --inflammato...

Besides phonation, what functions does the larynx fulfill? - - allows us to hold our breath - gives the upper body support to lift heavy objects through inspiring and clamping the vocal folds -tightly clamping the vocal folds aids in childbirth and deification What functions of the larynx are most important for sustaining life? - the larynx prevents unwanted objects from entering the airway through the strong and rigid closing of the airway via the vocal folds What are the 5 layers of t...

CCTC NUR 120 RESPIRATORY DISORDERS EXAM QUESTIONS AND ANSWERS Ventilation- - Correct Answer ️️ -movement of air in and out of the airways function of upper respiratory tract: - Correct Answer ️️ -warms and filters inspired air so that the lower respiratory tract (the lungs) can accomplish gas exchange or diffusion upper respiratory tract consists of: - Correct Answer ️️ -nose, paranasal sinuses, pharynx, tonsils, adenoids, larynx, and trachea where does gas exchange occur? - C...

adventitia - outermost layer of trachea/ Fibrous connective tissue that blends into adventitia of other organs of mediastinum Alveolar gas exchange - the swapping of O2 and CO2 across the respiratory membrane/ Air in the alveolus is in contact with a film of water covering the alveolar epithelium/ For oxygen to get into the blood it must dissolve in this water, and pass through the respiratory membrane separating the air from the bloodstream/ For carbon dioxide to leave the blood it must pa...
