Breath School Vocabulary

Question 1

Air hunger

Answer 1

the physical desire to breath triggered by increased CO2

Question 2

Suspension

Answer 2

holding breath on inhale

Question 3

Retention

Answer 3

retain from breathing on exhale

Question 4

Hypoxia

Answer 4

low oxygen in tissue

Question 5

Hypoxemia

Answer 5

low oxygen in blood

Question 6

Apnea

Answer 6

holding the breath

Question 7

Acidosis

Answer 7

becoming more acidic

Question 8

Alkalosis

Answer 8

becoming more alkaline

Question 9

Hypocapnia

Answer 9

low CO2 in blood

Question 10

Hypercapnia

Answer 10

high CO2 in blood

Question 11

Overbreathing

Answer 11

regularly breathing a greater amount of air than the body requires resulting in hypocapnia

Question 12

Vagal Tone

Answer 12

the electrical activity of the vagus nerve

Question 13

Heart Rate Variability (HRV)

Answer 13

variation in the time interval between heartbeats (in ms). A high variation points to a calm nervous system. A low variation points to a stressed nervous system

Question 14

Bohr Effect

Answer 14

the shift or uptake of oxygen caused by changes in the concentration of carbon dioxide in the environment

Question 15

Cellular Respiration

Answer 15

a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release byproducts.

Question 16

ATP - adenosine triphosphate

Answer 16

energy-carrying molecule found in the cells of all living things

Question 17

Aerobic

Answer 17

energy-generating process where oxygen is present

Question 18

Anaerobic

Answer 18

energy-generating process where oxygen is not present

Question 19

CO2 Tolerance

Answer 19

The ability to refrain from or slow down breathing under a higher amount of CO2. High CO2 tolerance causes better O2 uptake, thus energy production.

Question 20

Chemoreceptors

Answer 20

specialized sensory receptor cell which detect a change in the chemical composition of their immediate environment and signal a response

Question 21

Homeostasis

Answer 21

dynamic physiological processes that help us maintain an internal environment suitable for normal function

Question 22

Tensegrity

Answer 22

structural integrity that is produced by a system of dynamic tension
