His arterial blood gas (ABG) values are pH = 7.32, PaCO2 = 60 mm Hg, PaO2 = 50 mm Hg, HCO3 – = 30 mEq/L. His hematocrit is 52%…

1. Why did Allen’s heart rate and blood pressure fall in this time of emergency (i.e. at a time when you’d expect just the opposite homeostatic response)? Pg. 969 This occurred because Allen’s spinal cord has decreased perfusion due to damage, and a broken vertebral bone. Also, there has been a disruptions of the sympathetic…

This means, that it is the inflammation of the mucus producing layers on he bronchi. These layers are responsible for the protection of the bronchi. Bronchitis can be divided into…

The respiratory system is responsible for supplying our bodies with oxygen. This is done through respirations. There are two different respirations the external and the internal. The external respiration is the exchange of air between the lungs. This happens when oxygen is inhaled into the sacs of the lungs. Precisely at that time passes into…

Certain animals lack lungs and cannot survive in environments with inadequate lung function. Instead, these creatures rely on gills to obtain oxygen from water. It is noteworthy that the amount of oxygen present in water is just 1/20th of that found in the equivalent volume of air. Gills greatly increase the area available for gas…
