What is the primary role of the organs that absorb oxygen in terrestrial organisms?
What is the primary role of the organs that absorb oxygen in terrestrial organisms?
- To protect the body from external toxins
- To regulate body temperature
- To store energy for later use
- To facilitate the exchange of oxygen and carbon dioxide (correct)
Why are the surfaces that absorb oxygen described as fine and delicate?
Why are the surfaces that absorb oxygen described as fine and delicate?
- They are made from rigid materials
- They are located outside the body for direct exposure
- They must allow for efficient gas exchange (correct)
- They need to be very thick to withstand pressure
What adaptation do organs that absorb oxygen have in order to maximize their function?
What adaptation do organs that absorb oxygen have in order to maximize their function?
- They have no contact with air to prevent damage
- They are located deep within the body to preserve them
- They contain muscle tissue to enhance movement
- They increase their surface area for better contact with oxygen (correct)

Study Notes
Terrestrial Respiration
- Terrestrial organisms use atmospheric oxygen for respiration.
- Different organs absorb oxygen, each with a high surface area to facilitate gas exchange.
- This surface area needs to be thin and delicate to allow efficient oxygen and carbon dioxide exchange.
- The delicate surface is typically enclosed within the body to protect it.
- Air passages are necessary to transport air to the oxygen-absorbing areas.
- A mechanism for moving air in and out of the oxygen-absorbing area exists.
- Oxygen is absorbed by different organs in different animals.
- All these organs have a structure that increases the surface area in contact with the oxygen-rich atmosphere.
