Do humans have open or closed circulatory system's?
they have a closed circulatory sytsem:]yur welcome..... Sorry, this answer is very incorrect. A closed circulatory system means that the blood is contained within blood vessels, which the heart is able to pump/move through the tissues for very efficient gas exchange. Sponges DO NOT have this. In fact sponges do not even technically have a circulatory system at all, gas exchange is achieved by diffusion from the outer cells. So this means that sponges do not have an open or a closed circulatory system, because they don't have one at all.
What are Sponges' special adaptations?
All sponges have toxic substances inside of their bodies to discourage preditors to not attack them.it is a watery habitat
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.
What effect does emphysema have on the total area available for gas exchange?
It lowers the area available for gas exchange, therefore gas exchange doesn't happen as quickly or as much as it should.
Does sponge conduct electricity?
An insulator or neither. The water inside of the sponge is what would conduct electricity.
What system provides gas exchange between blood and air?
Capillary system is where gas exchange occurs
What do gas exchange systems have in common?
