Similarities between respiratory system of insects and fish?

Answer 1

Differences Birds

· For a bird to complete a full cycle of air flow, it must take two breaths.

· The "syrinx" serves as the "voice box" for all birds

· Air flow is unidirectional, moving to the lungs with a high oxygen content due to the air bags avoiding the used air coming in contact with the fresh air.

· Birds do not have a diaphragm. Air is transferred in and in of the respiratory tract by shifting pressure in the air sacs. Chest muscles force the sternum outward, making negative pressure in the air sacs and bringing air into the system.

· A bird's trachea size in comparison to their body size is large compared to human's trachea size.

· Respiratory infections can spread to the abdominal cavity and bones because bird's air sacs reach into the bones and have no diaphragm

· Lungs do not contract or expand, that takes place in the air sacs.

· Gas exchange takes place in the walls of microscopic tubules, named air capillaries.

· The respiratory system of bird is much more efficient than that of humans, taking in more oxygen with a single breath; however, this also means that birds are able to take in more toxins.

· Birds breathe at a slower rate comparative to their size than humans.

Difference people

· One breath completes a full cycle of air flow in humans

· The larynx serves as a voice box

· Air flow is bidirectional, moving in and out of the lungs, contaminating fresh air with used air

· The main muscle for breathing in humans is the diaphragm. When we breathe in, the diaphragm becomes smaller, the intercostals muscles become shorter and cause the ribs and sternum to rise up and the lungs stretch out, bringing air in.

· A human's trachea size in comparison to our body size is small compared to bird's trachea size.

· Respiratory infections cannot spread to the abdominal cavity and bones

· Lungs contract and expand for the air to be sucked in

· The exchange of oxygen and carbon dioxide takes place in microscopic sacs in the lungs named alveoli.

· Human's respiratory system may not be as efficient as birds, but it is much less vulnerable to poisons.

· Humans breathe faster in comparative to their size than birds.

Similarities Birds

· 2 lungs that are connected to a trachea

· They share many similar breathing oragans with humans, such as: nostrils, a nasal cavity, larynx, trachea, lungs, bronchus and sternum.

Answer 2

One, the exchange of carbon dioxide with oxygen.

Answer 3

The main difference between the excretory mechanisms in birds and humans is the design. Humans separate urine from feces while birds excrete both urine and feces from the same area.

Answer 4

Well, both are used to breathe oxygen. But the fish breathes oxygen from the water with gills. Humans breathe oxygen from air with lungs.

Answer 5

The respiratory system of fish and insects is sometimes similar. They both can derive oxygen from the water using specialized structures.

Answer 6

well us humans and birds excretory system is the same because it takes out waste.

Answer 7

The main respiratory organs of mammals are their lungs. Birds circulate air through a system of air sacs connected to their lungs, which allows for more efficient respiration.

Answer 8

They maintain a one-way flow of air.
