Types of respiratory systems Flashcards
What system do insects use
tracheal system
What are spiracles
small pores in the thorax and abdomen in insects that allows intake of air
What does trachea branches out into
tracheole
Adaptations of insects
Large number of tracheole provide larger total surface area
Thin and moist tracheole walls
Air sacs to speed up delivery respiratory gas during active body movements
Fish respiratory structure
Gills
What are gills made out of
Gill filaments supported by gill arch
Characteristics of gill filaments
Many thin and flat projections called lamella
Large number of filaments and lamellae provide large total surface area
Characteristics of lamella
thin membrane
supplied with many blood capillaries
Large quantity to increase total surface area
Three main adaptations
Moist surface
Thin respiratory structures
Large surface area
Frog respiratory structures
Skin and lungs
Characteristic of frog skin and it’s state in gaseous exchange
Inactive state
Thin and highly permeable to respiratory gases
Moist
Many blood capillaries beneath
Why are respiratory systems moist
To allow gas to dissolve and diffuse
Characteristics of frog lungs
Folded surface for increased total surface area
Thin
Moist
rich with network of blood capillaries
Human respiratory structure
Alveolus
Characteristics of alveolus
Large number of alveoli for increased total surface area
Moist and thin walls
Large network of blood capilarries
