hydra has no specialized respiratory organs and exchanges of gases take place via simple diffusion from surface lining of the enteron on so in this way the surface lining of enteron acts as an efficient respiratory surface
Common questions about the respiratory system include: How does the respiratory system work? What are the main organs involved in breathing? What are common respiratory conditions and their symptoms? How can lifestyle choices affect respiratory health?
Some important questions to ask about the respiratory system include: How does the respiratory system function to bring oxygen into the body and remove carbon dioxide? What are the main organs involved in the respiratory system and how do they work together? How does smoking or air pollution affect the respiratory system? What are common respiratory disorders and how are they treated?
The larynx belongs to the respiratory system.
The pharynx belongs to both the respiratory system and the digestive system. It serves as a passageway for air to travel from the mouth and nose to the trachea and for food to travel from the mouth to the esophagus.
The system that exchanges oxygen and carbon dioxide between blood and air is the respiratory system. This process occurs in the lungs, where oxygen is taken in from the air we breathe and carbon dioxide is released from the blood into the air we exhale.
Most jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems.
Jellyfish are, compared to mollusks, arthropods and vertebrates, very simple organisms. Jellyfish did not evolve a respiratory or an excretory system, as they can perform gas exchange at their outer surfaces.
Most jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems.
The respiratory system is the system that handles breathing.
The Respiratory System
The trachea is the airway in the respiratory system.
no, they do not have a respiratory system
* Jellyfish have nematocysts, or stinging cells used for defense and capturing prey. * They never stop growing. * They are actually older than dinosaur. * Box Jellyfish are the deadliest creatures in the world. * When removed from water, they collapse into a blob because of high water content * they are made of 95% water * they can absorb oxygen through their membrane-like skin * the amount of venom in a Box Jellyfish could kill 60 people * jellyfish kill more people than sharks * Upside-down Jellyfish has algae growing in its tentacles so it must live in shallow water. * The box jellyfish has 24 eyes, yet it still has blurry vision. * Jellyfish have no brain, respiratory system, circulatory system, or excretory system, so they use their mouth for "waste expulsion" * The Box Jellyfish has 64 anuses.
