In order from closest to furthest what are the layers of the Atmosphere?
Troposphere
stratosphere
mesosphere
thermosphere
What is Dalton’s law of partial pressure?
The total pressure exerted by a mixture of gases is equal to the sum of pressures contributed by each gas in the mixture
What are the physiological zones of the atmosphere?
Three

What type of tissue is blood considered to be?
Connective tissue
What is the purpose of plasma in blood?
To transport nutrients such as glucose and waste products
Define respiration
The physical and chemical process of an organism by which oxygen is transported to tissues and cells and waste products like CO2 and water are given off
What chemical in the body is used to maintain the acid base balance?
CO2
Exhaling warm moist air aids in what process?
Maintaining body temperature
Tiny air sacs in the lungs where gas exchange takes place is called what?
Alveoli
Define hypoxia
State of O2 deficiency in the blood cells and tissues significant enough to cause impairment of function
What are the four major types of hypoxia?
Hypoxic, hypemic, stagnant, and Histotoxic
What are the four stages of hypoxia?
Indifferent, compensatory, disturbance, and critical
