Oxygenation Study Guide With Complete Solution

Concept of Oxygenation ANS - The mechanism that facilitates (or impairs) the body's ability to supply oxygen to all cells of the body. - Function: Obtain oxygen from atmospheric air; transports this air through the respiratory tract into the alveoli. - Achieved through respiration, the process of inspiration & expiration. -O2 to alveoli to be exchanged for CO2 which is then expelled from the body. -Ventilation is the actual exchange of O2 & CO2. Ventilation ANS ______ is the actual exchange of O2 and CO2. Alveoli ANS ____ is where the gas exchange occurs Oxygenation on a grid of severity ANS Normal - URI (Upper Respiratory Tract Infection) - Asthma - COPD (Chronic Obstructive pulmonary disease)- Pneuomnia - ARDS (Acute Respiratory Distress Syndrome)- Resp. Failure/Death Order of airflow ANS 1) Nasal Cavity 2) Pharynx 3) Trachea 4) Bronchi 5) Bronchioles 6) Alveoli 7) Oxygen & CO2 exchange at the alveoli 20,000 ANS The body breathes about ______ times. By the time we reach 70 years old, that's about 600 million breaths. Trachea ANS - Known as the wind-pipe. Which is a 2-3 cm tube extends downward from the bottom of the larynx for about 12 cm. Lined with tiny hairs. Divides into two branches. Pharynx ANS -Located at the back of the throat & carries both food and air and used for digestion and respiration. Esophagus ANS A path that brings food that leads to the stomach. Epiglottis ANS - A flap that covers the air only passage when we swallow.. This stops food and liquid from going into the lungs. Bronchioles ANS Tubes in the lungs which branch off from the larger bronchi that enter each lung, from the large and singular trachea which connects to the mouth.
