Respiration

Respiration

Respiration

Uptake of oxygen and disposal of carbon dioxide.

Cellular respiration

A process where cells need oxygen to make ATP and release carbon dioxide

diffusion

Respiration involves the ________ of gases across plasma membranes

Gills

Aquatic respiratory organs Extensions of tissues Increase the diffusion surface area

Skin

Respiration in Amphibians occur through the lungs and the ______

Process of respiration in Amphibians

Force air into their lungs this creates a higher pressure in the air outside their lungs Air fills the buccal cavity close nose and mouth floor of mouth is raised air is forced into the lungs

Moist

Skin must be kept _____ in order for diffusion to take place.

Metabolic

mammals have higher _________ rates to maintain a body temp

Mouth/Nose

first part of air entering

Pharynx

Second part of air entering

Larynx

Third part of air entering

Trachea

Fourth part of air entering

Bronchi

Fifth part of air entering

Bronchioles

Sixth part of air entering

Alveoli

Seventh part of air entering

Nostril

Conducts air into hollow nasal cavity

Nose Hair

help filter and prevent things from entering the respiratory tract

Turbinates

Thin bones in nasal cavity to increase surface area and secrete mucous Lined with capillaries that moistens air

Sinuses

producing mucus that moisturizes the inside of the nose protects the nose from harmful things

Pharynx

Connects the mouth to the throat

Glottis

Opening to the trachea

Epiglottis

flap of cartilage located behind the tongue that helps prevent food from entering trachea

Larynx

houses the vocal cords Have 2 folded structures of the vocal cords.

Large

When you breathe normally there is a _______ gap between the vocal cords.

Contract

when you speak, muscles ________ bringing cords closer. The air that passes through them vibrates the cords producing sound.

Trachea

Flexible tube that is the passageway of air supported by semi-circular cartilage rings to ensure it does not collapse with esophagus Lines with ciliated cells that secrete mucous

Ciliated cells

secrete mucous prevents foreign particles to enter the system

Bronchi

2 smaller branches of the trachea

Bronchioles

tiny subdivisions of the bronchi

Alveoli

grape like clusters of tiny sacs at the end of bronchioles Kept moist site of gas exchange have high surface area surrounded by capillaries

Lungs

flexible membrane that allow expansion and contraction Houses part of the bronchi, bronchioles, and alveoli

Pleura

A layer of tissue that envelopes the lungs A flexible membrane that allows the lungs to expand and contract
