It is the source of oxygen (air for terrestrial animals, water for aquatic animals).

Q: What is a higher oxygen concentration/being easier to pump?

This is an advantage of air being the respiratory medium as opposed to water.


A: What is keeping respiratory cells moist?

This is an advantage to water being the respiratory medium instead of air.


A: What is gas exchange?

The uptake of O and the discharge of CO .


A: Thin, moist, large surface area

Characteristics that maximize gas exchange across respiratory surfaces?


A: What are gills?


Outfoldings of the body surface thatare suspended in water; used by manyaquatic animals for gas exchange

A: What are lungs?

Respiratory organs used by terrestrial animals; all respiration occurs in one place


A: The gases diffuse across themembrane of every cell in the body.

The simplest animals (sponges, cnidarians, and flatworms) respirate this way.


A: What is tracheal system/trachea?

Branched air tubes that extend to every section in the body, used by insects for respiration


A: What is they respirate across their entire outer skin?

Process by which earthworms and amphibians respirate


A: Breathing…seriously.


What is the inhalation and exhalation of air?

A: What is positive pressure?

The type of pressure by which amphibians respirate that involves drawing air into the oral cavity, then forcing it down the trachea.


A: What is negative pressure?

The type of pressure by which mammals respirate…PULLING air into the lungs.


A: What is the medulla (oblongata)?

The part of the brain that sets breathing rhythms based on the pH in the brain fluid


A: What are air sacs? (posterior and anterior)

The adaptation that allows birds to renew air in lungs and have higher oxygen concentrations


A: What are pulmonary veins?


Type of blood vessels that circulate gas from the high pressure lungs to the heart

A: What are arteries?


Type of blood vessels that circulate gases from heart to low pressure tissue cells

A: What are hemoglobin and hemocyanin?

The most abundant oxygen transporting respiratory pigments


A: What is partial pressure?

The proportion of atmospheric pressure contributed by a single gas.


A: The drop in pH caused by presence of CO2.

The reason more carbon dioxide causes hemoglobin to release the oxygen bound to it.


A: What is oxygen?

Extremely active mammals consume large amounts of this gas.

A: What is carbon dioxide?

Gas besides oxygen that hemoglobin transports.


A: What are anterior air sacs?


Type of air sacs that push stale oxygen out of bird lungs

A: What is myoglobin?

Diving mammals use this to store oxygen in the blood


A: Blood and water move in opposite directions. As blood gains more oxygen, it encounters water with ever-higher concentrations of oxygen, so there is always a diffusion gradient.

An explanation of countercurrent exchange.
