Gas exchange 3 ;1

Aveolar Sacs

Clusters of thin walled air sacs ( alveoli) at the end of the bronchioles in mammalian lungs where gas exchange with the blood occrus.

• Tiny air sacs mammal lungs where gas exchange happens

• Alveoli = gas exchange

Book Lungs

Respiratory open found in spider and some other arachnids, made of stacked, blood filled leaf like plates that exchange gases with air in a chamber

• Respiratory organs in spider/arachnids made of stacked plates for gas exchange

• Spider = Book lungs

Buccopharyngeal pressure

Breathing mechanism used by amphibians in which the floor of the mouth is raised to force air into the lungs ( rather than using a diaphragm to pull air in )

• Amphibians raise the floor of their mouth to push air into the lungs

• Amphibian = Mouth pump

Cutaneous Respiration

Gas exchange that occrus directly across the skin

Diaphragmatic Breathing

Breathing methods in mammals in which contraction/ relaxation of the diaphdram changes thoracic cavity volume, drawing air into and pushing it out of the lungs

• Mammals use the diaphragm to change lung volume and move air

• Mammals= diaphragm

Expiratory Reserve Volume

The additional volume of air that can be forcibly exhaled after a normal, passive exhalation. Biggest exhale

• Extra air you can force out after a normal exhale

• Exhale= Biggest exhale

Gills

Respiratory organs that extract dissovled oxygen from water, usually via countercurrent exchange. Extend into breathing medium

• Structures that take 02 from water

• Gills= water

Inspiratory Reserve volume

THe additional volume of air that can be forcibly inhaled after a normal inhalation. Biggest inhale

• Extra air you can force in after a normal inhale

• Inhale= biggest inhale

Lungs

Invaginated, internal, sac like or spongy respiratory organs

• Internal, sac like respiratory organs used for gas exchange

• Lungs= air

Multicameral

Type of lung structure with multiple internal chambers. compartments ( many chambers), as opposed to unicameral: increase surface area for gas exchange.

• Lungs with many chambers, increasing surface area

• Multi= many

Parabronchi

Small air passages in bird lungs through which air flows in a continuous, largely one directional path, allowing highly efficient gas exchange.

• Small air passages in bird lungs where air flows and gas exchange occrus

• Birds= Parabronchi

Residual Volume

The volume of air that remains in the lungs after the most forceful possible exhalation; cannot be voluntarily expelled.

• Air that stays in the lungs after the strongest exhale

• Residual = Remains

Respiratory Exchange membranes

Separates internal tissues of the animal & evironment. Thin, moist surfaces across which gases diffuse between an organism and its evironment

• Thin, moist surfaces where 02 and CO2 diffuse between the animal and evironment

Spiracle

External opening of the tracheal system in insects and some other arthropods, through which air enter and exits

• Opening where air enter/ exits insects

• Insect= spiracle

Tida volume

The volume of air move into or out of the lungs during a single, normal resting breath

• Air moved during one normal breath

• Tidal = normal breathing

Tracheal System

Network of internal air filled tubules ( Tracheae) in insects that delivers air directly to tissues, bypassing the cirulatory system for gas transport

• Tubes in insects that carry air directly to tissues

• Insect tubes = Cells

Unicameral

Type of lung structure with a single internal chamber ( one large open space) as opposed to multicameral

• Lung with one chamber

• Uni= one

Ventilation

Mass flow of air or water to from membrane

• Moement of air or water to and from the respiratory membrane

• Ventilation= Moving air/ water
