What is an pleura?
A pleura is a serous membrane that lines the lungs and chest cavity of humans and mammals. It is a closed area that helps the lungs during respiration.
What types of animals can be found in the designated animal area?
Various types of animals can be found in the designated animal area, including mammals, birds, reptiles, and amphibians.
What is an ampihibians breathing method?
The way amphibians breath is diffusion (when particles, or in this case gas particles, move from a high concentrated area to a less concentrated area) of the skin. They DO have lungs, but have other uses for them.
What are the advantages of mammals having internal lungs?
Having internal lungs allows mammals to efficiently exchange gases with a large surface area, maximizing oxygen uptake from the air. It also helps protect the lungs from drying out and injuries. Additionally, internal lungs provide a better control over the breathing process, enabling mammals to regulate their respiration rate as needed.
How do the lungs of a frog differ from those of the pig?
The lungs of a pig is larger and more evolved than that of a frog. This is because the frog has other organs of respiration apart from the lungs e.g the skin (cutaneous respiration) and mouth(buccal respiration) hence does not depend on the lungs solely for respiration unlike the pig which has thev lung as its only respiratory organ
What does the alveoli of the lungs of a mammal do?
The alveoli are tiny air sacs in the lungs of mammals that are crucial for gas exchange. They provide a large surface area for oxygen to diffuse into the bloodstream and for carbon dioxide to be expelled from the blood. The thin walls of the alveoli, along with their extensive capillary networks, facilitate this efficient exchange, allowing mammals to breathe and sustain cellular respiration.
Why do mammals have large numbers of alveoli?
There are about 300 million alveoli in each of your lungs. These tiny air sacs provide an ideal site for the diffusion of gases into and out of the blood.The alveoli have a very large surface area. In fact if all of the alveoli in your lungs were spread out flat they would cover the area of a tennis court. This large surface area is the result of all the alveoli being small spheres. It is another example of the importance of the surface area: volume ratio.
Why organisms does not need lungs or gills to obtain the oxygen?
Some organisms, such as certain amphibians, worms, and single-celled organisms, can directly absorb oxygen through their skin or cell membranes in a process called diffusion. This method is effective in moist environments where oxygen can easily pass through their surfaces. As long as they have a sufficiently large surface area relative to their volume and live in environments where oxygen is adequately dissolved in water or moisture, they can meet their respiratory needs without specialized structures like lungs or gills.
What has the author Derek Whiteley written?
Derek Whiteley has written: 'Amphibians and reptiles of the Sheffield area' -- subject(s): Reptiles, Amphibians
Why do amphibians like moist area?
they need to keep there skin moist
What does herpetologist studie?
They study an area of zoology involving reptiles and amphibians.
Do lungs have a large exposed surface area?
Your lungs have very large surface area. About 100 square meters or 1100 square feet.
