What animal breath through lungs and the body is covered with scales?
snakes. The body of the snakes are covered with scales and breathe through lungs
Which structure protects the lungs?
the rib cage
Why does the surface of the lungs need to be covered with Pleura?
The surface of the lungs is covered with pleura to provide a smooth, frictionless surface that allows the lungs to expand and contract easily during breathing. This double-layered membrane also helps to create a pressure gradient that facilitates lung inflation. Additionally, the pleura serves as a protective barrier, reducing the risk of infection and injury to the lung tissue.
Describe the texture of a cat's lungs?
A cat's lungs have a spongy and elastic texture, with numerous small air sacs called alveoli that help in the exchange of oxygen and carbon dioxide during breathing. The lungs are covered by a thin membrane called the pleura that aids in smooth breathing movements.
What covers the surface of the lungs?
The lungs are covered by a thin, double-layered membrane called the pleura. The inner layer (visceral pleura) covers the lungs themselves, while the outer layer (parietal pleura) lines the chest cavity. This arrangement creates a seal that allows the lungs to expand and contract during breathing.
What are the tiny air sacs within the lungs that are made of a single layer of squamous epithelial tissue and are covered with very small capillaries?
alveoli
Why is oxygen poor blood pumped to the lungs?
The lungs take in oxygen, this oxygen travels down to the alveoli (thin, permeable sacs), which are covered in blood vessels, and the oxygen travels into the blood due to a pressure difference and CO2 goes from the blood to the lungs to be exhaled. The body needs that oxygen for almost every system in the body.
What is the physical appearance of the lungs?
"Gross anatomy" means the anatomy visible without the use of a microscope. The lungs are a pair of sac-like, pinkish organs that sit above the diaphragm. Each lung is covered in a network of capillaries that allow the gas exchange (oxygen into the blood, carbon dioxide out) with the blood. The capillaries attach to the pulmonary arteries which go to the heart. The left and right lungs sit on either side of the vertebral column and heart.
Show picture of a healthy lung?
A smokers lungs are black and covered in a yellowish substance called infection. Once a smoker stops smoking, there lungs begin to heal themselves. The longer you stay not smoking the better your lungs will get.
What does the cartilage in lungs do?
The lungs don't have cartilage as such, the main "tubes" into the lungs have bands of muscle and cartilage to give them structure, because the lungs are very wet as they are covered in mucus if there was no support they would stick together and be held shut by surface tension (have you ever put a wet saucepan lid on to a work surface and couldn't remove it? same principle) if the tubes were stuck shut obviously you wouldn't be able to breathe :/
Why are people evacuated during an eruption?
The volcanic ash produced by the eruption is very bad for the lungs and also ofcorse because they don't want to be covered in lava
What is the difference between crocodile and frog?
A crocodile can eat a frog. The main difference is that crocodiles are reptiles and frogs are amphibians. Crocodiles have lungs from the time they hatch, but frogs first breathe using gills and a spiracle (when they're tadpoles) and develop lungs as they grow.
