Inhaled air passes through the primary bronchus, and most enters the posterior air sacs as well as the lungs. During this passage, air that was in the posterior air sacs moves through the lungs air capillaries so that exchange takes place. During exhalation, the air in the posterior air sacs passes through the lung en route to the external environment. Again exchange goes on during exhalation.

What is the difference between fish and birds?
Fish are aquatic vertebrates that have gills for breathing and fins for swimming, while birds are feathered, warm-blooded, egg-laying vertebrates with wings for flying. Fish live in water, while birds predominantly live on land and in the air.
Birds have and mammals have?
Birds have feathers and lay eggs, while mammals have fur or hair and give birth to live young. Birds also have beaks and lungs that incorporate air sacs, while mammals have specialized teeth and a diaphragm for breathing. Both birds and mammals are warm-blooded vertebrates with a backbone.
Why do most birds not prey on hypolimnas?
Most birds do not prey on Hypolimnas butterflies because they are unpalatable due to their toxic compounds acquired from their larval host plants. These compounds make them distasteful and potentially harmful to predators, leading to a learned avoidance behavior. This phenomenon, known as aposematism, serves as a form of defense mechanism for the Hypolimnas butterflies against predation by birds.
Why was there a big group of Black birds in a heart shape hovering in the sky?
Large groups of black birds, such as starlings or crows, often gather in mesmerizing formations like murmurations or shapes like hearts as a defensive mechanism against predators. This behavior helps to confuse and deter potential threats like birds of prey.
Why don't penguins have gills?
Penguins are birds and are adapted to live in water and on land. They have lungs for breathing air, like other birds. Gills are specialized organs found in fish and some other aquatic animals that allow them to extract oxygen from water. Penguins have evolved to breathe air efficiently despite spending a lot of time in the water.
Describe the mechanism by which you inhale and exhale?

What is mechanism of CARP?

What is the defense mechanism of tundra swans?

What is the energy supply of speech?
Its the breathing mechanism, consisting of the lungs and the diaphragm and intercostal muscles.
Do penguins breathe oxygen on the air or water?
Penguins are birds and like all birds they get oxygen by breathing air.
What organ do cassowaries use for breathing?
The Southern Cassowary (like all birds) has a pulmonary system where the lungs and the mouth are all connected.
Did birds first begin to fly in the pre-Cambrian period?
No. Birds are air breathing vertebrates, there were no air breathing animals in the Precambrian. The earliest bird fossils are found in rocks about 160 million years old in the Jurassic period.
Do pelicans have nostrils?
All birds have lungs for breathing, as mammals and other animals.
What are in ventilators?
Ventilators consist of a flexible breathing circuit, gas supply, heating/humidification mechanism, monitors, and alarms
