Gas Exchange and Transport

3-carbon isomer that binds with deoxygenated hemoglobin that decreases hemoglobin's ability to bind with oxygen

decrease in blood pH level

increase in blood pH level

cavity in the lungs where gas exchange takes place

weakening of the bonds between hemoglobin and oxygen

any of a vast network of tiny vessels that enable the exchange of nutrients, gases, and wastes between tissues and blood

total gas pressure in a system is the sum of the pressures of each individual gas in that system

hemoglobin that is no longer attached to an oxygen molecule

series of nerves that collects information from the peripheral nervous system and chemoreceptors and sends it to the ventral respiratory group

normal, unlabored breathing

anticipatory response that initiates the feedback loops involved with the action

weakening of the bonds between hemoglobin and carbon dioxide

protein found in red blood cells responsible for carrying 98.5 percent of all oxygen in the blood

special form of hemoglobin found in a fetus that has a higher affinity for oxygen

states that gases dissolving in liquids will do so in proportion to their partial pressures

increased carbon dioxide levels in the brain

increased depth and rate of breathing in response to higher metabolic demands of the body

reduced carbon dioxide levels in the body

drop in normal oxygen level in the blood that induces the ventral respiratory group to increase breathing to restore blood oxygen level back to normal

molecule formed when oxygen binds with hemoglobin

graph that shows how partial pressures in the lungs and tissues change in their oxygen saturation based on oxygen concentrations in the blood

pressure put forth by each of the gases in a system, where the pressure is directly proportional to the amount of the particular gas

fluid with lipoprotein that coats the surfaces of the alveoli and keeps them from collapsing during expiration

network of nerves that extends from the spinal cord to the site where the pons and medulla oblongata meet and creates the rhythm of breathing
