Earthworms do not have lungs, however, they breath through their skin like other aquatic animals.
because its respritory system is in direct contact with a watery environment
yes a eartworm has a external resptory system
the oxygen diffuses to their circulatory system through the skin
The air around the earthworm goes through the skin.
Actually, earthworms have no respiratory system at all, they get the oxygen and nitrogen that they need from the soil.
You DO find a respiratory structure in each segment of the earthworm. An earthworm uses its skin as the respiratory structure. Oxygen in the air dissolves in the moisture and mucus on the skin then diffuses into blood capillaries close to the skin to be transported to the rest of the body.
multicellular organisms obtain their oxygen through the respiratory system
This is because the earthworm takes in oxygen through its skin and releases CO2 through it's skin as well using diffusion
the respiratory system brings oxygen into the body
The name of a cell that has stopped assembling ATP is anaerobic, meaning to be without oxygen. What occurs is Anoxia: a situation in which there is no available oxygen in the cell. Without oxygen the respiratory chain stops, there is no ATP production, the cell does not obtain energy and then dies.
Earthworms breath through their skin, earthworms diffuse oxygen through a network of thin-walled capillaries which are found just under the skin.
The circulatory and respiratory systems work together to get oxygen to cells. Oxygen transfers from the respiratory to the circulatory system at the capillaries surrounding the alveoli.
The respiratory system provides the mechanism for the body to obtain oxygen and excrete carbon dioxide.
1. Aerobic - with oxygen 2. Anaerobic - without oxygen 3. Facultative Anaerobic - with or without oxygen
Respiration by the entire exterior versus by staggered openings is the way that the respiratory organs of the grasshopper are different from those of the earthworm. The annelid in question manages to take in oxygen and to release carbon dioxide as long as the outside of the worm's body is moist. The insect in question uses spaced holes, known as spiracles, to release carbon dioxide and to transport oxygen to the trachea.
