Gills greatly increase the surface area for gas exchange. They occur in a variety of animal groups including arthropods (including some terrestrial crustaceans), annelids, fish, and amphibians. Gills typically are convoluted outgrowths containing blood vessels covered by a thin epithelial layer.

How does gas exchange occur in animals?
In animals, gas exchange follows the same general pattern as in plants. Oxygen and carbon dioxide move by diffusion across moist membranes. In simple animals, the exchange occurs directly with the environment. ... Hemoglobin binds loosely to oxygen and carries it through the animal's bloodstream.
How does gas exchange occur in terrestrial insects?
Insects breathe through a complex network of tubules, the tracheae. Large tracheae connect to spiracles opening at the surface of the body, where air enters and carbon dioxide exits.
What is the respiratory organ of terrestrial animal?
⏩Terrestrial animals - Lungs. ⏩ Aquatic animals - Gills.
What is the organ that exchanges gas?
The lungs are the place where gas exchange with air takes place (in fish, gills serve the same purpose). Oxygen-deficient blood coming from cells picks up oxygen from the air in the lungs.
How are terrestrial mammals adapted for gas exchange?
The large number and small size of the alveoli gives the lungs a large surface area to volume ratio. This allows mammals to grow to much larger sizes without the limitations normally imposed by the associated increase in the size and weight of the gas exchange system.
In which organ do gas exchange and gas transport occur?
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
How does gas exchange occur in mammals?
In mammals, air is warmed and humidified in the nasal cavity. Air then travels down the pharynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles, which house the first site of gas exchange.
What is the function of spiracles in insects?
Insects have spiracles on their exoskeletons to allow air to enter the trachea. In insects, the tracheal tubes primarily deliver oxygen directly into the insects' tissues. The spiracles can be opened and closed in an efficient manner to reduce water loss.
What is spiracles and its function?
A spiracle is an opening found on the outside of an insect's exoskeleton that is used for breathing. There are numerous spiracles on the body of an insect, typically paired and present on the thorax and abdomen. ... Hairs keep dust from entering the spiracle. A spiracle leads to a trachea, or air tube.
What is cutaneous gas exchange?
Cutaneous respiration, or cutaneous gas exchange (sometimes called, skin breathing), is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs.
How do terrestrial animals breathe?
Terrestrial (land) animals, inhale air through their noses, mouths, and even their skin, to bring oxygen to their lungs. ... Gills extract oxygen from water and send it into the fish's blood stream. For this reason, most fish, and other aquatic animals that get oxygen from water, can't survive on land very long.
What gas is used by animals and plants in their respiration breathing process?
Animals and plants need oxygen. When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration.
Where does gas exchange occur in birds?
Gas exchange takes place between the air capillaries and blood capillaries, making this surface analogous to the alveolar surface in mammals. There are several important differences in the mechanism and pattern of lung ventilation in birds compared with other vertebrates with lungs.
Why is gas exchange important in animals?
The Need For Gas Exchange
Cellular respiration is the process by which cells convert energy rich molecules (food) into a form of energy that is easily utilized by cells, called ATP. ... Efficient gas exchange ensures enough oxygen is supplied / carbon dioxide is removed in order to maintain cellular energy levels.
How are gases exchanged?
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
