What are two structures in animals that serve the same purpose as lung?

One of the products of cellular respiration is carbon dioxide. Your respiratory system also helps your body get rid of that carbon dioxide. While you have lungs, fish have gills that serve as the location for that transfer of gases.

What characteristics can you observe in the gills that make them an efficient respiratory organ?

Gills are very efficient at removing oxygen from water: there is only 1/20 the amount of oxygen present in water as in the same volume of air. Water flows over gills in one direction while blood flows in the opposite direction through gill capillaries. This countercurrent flow maximizes oxygen transfer.

Why are gills so widely seen in aquatic animals but not in land animals?

Explanation: Because aquatic animals are surrounded by fluid which keeps the gills moist and able to function by exchanging gases with the environment. Land animals are not surrounded by fluid so in order to exchange gases their gill analogs (lungs) have to be internal where they can be kept constantly moist.

What features of respiratory structure makes the respiration more effective?

(i) It has large surface area and branched. (ii) Contain an extensive network of blood vessels. (iii) It is thin, delicate and fine.

Which structure does the trachea lead to in the lungs?

At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs. Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles (BRAHN-kee-olz).

How are gills and lungs similar and different?

"Their primary purpose is to exchange gases, take oxygen in and release carbon dioxide out of the fish." Both lungs and gills have a bed of very small blood vessels with thin walls that the gases can easily travel across. But gills have a much harder job than lungs, Malison says.

Do crabs have lungs or gills?

Crabs, like many sea-dwelling creatures, have gills that they use to extract oxygen from the water in order to breathe.

Can animals with gills survive on land?

Gills serve the same purpose as our lungs do. 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 are the characteristics of respiratory structures present in animals?

(i) All respiratory organs have large surface area to get enough oxygen. (ii) They are thin-walled for easy diffusion of gases and substances. (iii) They have rich supply of blood for transporting respiratory gases.

What is the similarities of respiratory system and circulatory system?

The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Which structure is also known as the windpipe?

The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people. The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum). The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung.

Which structure is also called the windpipe the pharynx the larynx the trachea the bronchus?

The trachea, also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi.

What are the two tubes called that lead to the lungs?

Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung.

How do lungs and airways compare among birds and mammals?

The mammalian lung has reciprocating ventilation with large terminal air spaces (alveoli) while the avian lung has a flow-through system with small air capillaries. As a result the environment of the pulmonary capillaries is very different between the mammals and birds.

What animals have both lungs and gills?

Lungfish have a unique respiratory system, having both gills and a lung. It is the only type of fish to have both organs, and there are only six known species around the world.

Are gills and lungs same?

Gills are evaginations of the body surface. Some open directly to the environment; others, as in fishes, are enclosed in a cavity. In contrast, lungs represent invaginations of the body surface. Many invertebrates use gills as a major means of gas exchange; a few, such as the pulmonate land snail, use lungs.
