Gas exchange in lancelets occurs primarily through their skin and gills. As water flows over the gill slits, oxygen diffuses from the water into the lancelet's blood, while carbon dioxide diffuses from the blood into the water. This process is facilitated by the lancelet's position in the water and its constant movement, which helps maintain a flow of water over the respiratory surfaces. Overall, the thin-walled gills and skin provide a large surface area for efficient gas exchange.

What type of land animals are able to exchange oxygen and carbon dioxide through their skin?
Amphibians, such as frogs and salamanders, are able to exchange oxygen and carbon dioxide through their skin. Their skin is thin, moist, and highly vascularized, allowing for this gas exchange to occur.
Is lancelet living or nonliving?
A lancelet is a living organism. It is a type of marine invertebrate with a simple body structure, similar to that of a fish. Lancelets are considered living organisms because they exhibit characteristics of life such as growth, reproduction, and response to stimuli.
Can manometers be used to record any metabolic gas exchange?
Manometers are typically used to measure pressure, so they are not commonly used to directly measure metabolic gas exchange. For recording metabolic gas exchange, methods such as gas analyzers or respiratory gas exchange systems are more commonly used because they can measure specific gas concentrations in exhaled breath.
Why is water always lost from the gas exchange surface?
Water is lost from the gas exchange surface of terrestrial organisms because gases must be exchanged with air. Terrestrial organisms have a high water potential, therefore when the gas exchange occurs water will be lost.
The relationship between the animal's type of gas exchange system and it's environment?
An animal's type of gas exchange system is influenced by its environment. Animals in aquatic environments may have gills for efficient gas exchange with water, while terrestrial animals often have lungs to extract oxygen from air. Some animals like insects have a tracheal system for gas exchange that connects to almost every cell in their body. The type of gas exchange system an animal has is adapted to meet the specific oxygen requirements and environmental conditions of its habitat.
Where in the respiratory tract does gas exchange occur?
The gas occurs by simple diffusion through the cells.
Where does the majority of gas exchange occur?
the alveolus
Where does gas exchange occur in seaweed?
in the leave
How does gas exchange occur in sponges?
gills
Where does gas exchange occur?
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
What is the purpose of the atrial cavity in a lancelet?
The atrial cavity in a lancelet serves as a space that facilitates the flow of water through the organism's body. It plays a crucial role in respiration and feeding by allowing water to pass over the gills, where gas exchange occurs and food particles can be filtered out. This cavity helps maintain the lancelet's simple body plan while supporting its basic physiological functions.
How does gas exchange occur in clown fish?
in their gills.
Where in the respitory tract does gas exchange occur?
In the alveoli
Where does gas exchange occur in fetal pigs?
lungs
Is gas exchanged in the pleura?
Gas exchange does not occur in the pleura. The pleura is a membrane that lines the outside of the lungs and inside of the chest cavity. Gas exchange, where oxygen is taken in and carbon dioxide is removed, happens in the alveoli of the lungs.
What surrounds the alveoli in the lungs to allow gas exchange to occur?
Capillaries
Where in the repiratory system does gas exchange occur?
Between the avioli and the lungs.
