Why is walking important to the crayfish respiration?

Walking helps crayfish circulate water over their gills, which is crucial for respiration. As crayfish move, they create rhythmic movements that draw oxygen-rich water over their gills and expel carbon dioxide, facilitating gas exchange for respiration. Additionally, walking allows crayfish to adjust their position to ensure they are in an optimal environment for obtaining oxygen from the water.


Why do crayfish gills have a large surface area?

The gills are feathery so it has more surface area, allowing more gas exchange! By gas exchange u mean to take in oxygen and let out carbon dioxide, right?


Is gas exchange a function of the digestive system?

Gas exchange is a function of respiration not digestion.


What is the elastic unit of the respiratory system where gas exchange occurs?

Alveoli is where gas exchange occurs.


Of the crayfish systems what two are the most unlike the humans systems?

The excretory system of crayfish, which involves specialized structures called green glands for waste removal, is unlike the human excretory system, which primarily relies on the kidneys. The respiratory system of crayfish, which involves gills for gas exchange, differs from the human respiratory system that uses lungs.


Why does a crayfish move its walking legs in a rhythmic back and forth motion when it is lying with one side of its carapace near the surface of the water?

A crayfish moves its walking legs in a rhythmic back-and-forth motion to facilitate respiration and maintain water flow over its gills. This movement helps to create currents that draw oxygen-rich water into the branchial chamber, allowing for efficient gas exchange. Additionally, this motion can assist in stabilizing the crayfish while it rests on the substrate or surface.


What do gas exchange systems have in common?

The exchange surfaces are moist.


What is the name for exchange of gas in the lungs?

Where does gas exchange occur?

gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries


What are the actual sites of gas exchange within the lungs are the?

The actual sites of gas exchange within the lungs are the alvioli.


How does the gas exchange take place in flatworms?

worms carry out gas exchange by absorbing air through their skin


What is the site for gas exchange?

the organ that is involved in gas exchange is the lung. the specific lung structure that is the site for gas exchange is the alveolus which is part of the alveoli, which is found in the lung.
