After repeated experiments, Griffin had discovered how to make the human body transparent. This was a big achievement. However, he misused his discovery for personal gains and for hurting others. Thus, though he can be termed as a brilliant scientist, he was not a noble one.

◆ Bronchi - A bronchus is a passage of airway in the respiratory system that conducts air into the lungs. Trachea divides into primary bronchi. Primary bronchi divide into secondary bronchi which further divide into tertiary bronchi. Bronchi are made of smooth muscles. Flow of air in respiratory tract is as follows - nostrils -> nasal cavity -> pharynx -> larynx -> trachea -> primary bronchus -> sec bronchus -> ter bronchus Read more on Brainly.in - https://brainly.in/question/1450976#readmore

Breathing by mouth is harmful in the sense that the air which is taken in is not filtered , it is taken in with its impurities . Hence it is said that we should not breathe by mouth and always breathe via our nose. The nasal way of breathing is the best way because our nose contains nasal hair which are tiny hair inside the nose which filter the air and make it purified and hence safer .

Large animals have advanced respiratory system that allows them to take in oxygen and give out carbon dioxide.

Lungs are usually present in such animals where the exchange of gases takes place.

Blood carries oxygen from the lungs to every cell of the body and then takes carbon dioxide from cells back to lungs.

The arrangement in the bodies of large animals to meet oxygen requirement is a respiratory pigment in the blood called hemoglobin.

Oxygen is present when this form of respiration takes place. Oxygen is absent when this form of respiration takes place.
Gases are exchanged in this form of respiration. Gases are not exchanged in this form of respiration.
It can be found in the cytoplasm and the mitochondria. It can be found only in the cytoplasm.
Glucose breaks down into carbon dioxide and water. Glucose breaks down into ethyl alcohol, carbon dioxide, and energy
All higher organisms such as mammals have this type of respiration. Lower organisms such as bacteria and yeast use this type. In other organisms, it occurs during heavy activities

Breathing cycle is rhythmic because it is a regular process of inspiration and expiration  in an oscillating cycle. Neuronal impulses are responsible for this control which transmits between the respiratory centers in the brain and the muscles involved in inspiration in the chest and diaphragm.

Gaseous exchange is a continuous process because it involves the process of diffusion. Diffusion of gas takes place from the region of high concentration to a region of low concentration which normally involves exchange of oxygen and carbon dioxide during the process of respiration in living organism and its environment.

C-shape rings of cartilage are present to prevent trachea to collapse when there is no air

Yogita Ingle 5 years, 8 months ago

The "walls of trachea" are supported by "rings" to restrict it from "collapsing". "Trachea" is also referred as "windpipe" as it provides a "passage for air" and carries it to the lungs. In humans, this is a part of the "respiration" process. The "air" enters the hair and mucus lined nostril. It then passes through the trachea and enters the lungs. "Trachea" bifurcates into "bronchi" which further divides into alveoli where exchanges of gases takes place.

It's covered by blood so that the exchange of gases can take place between the members of the alveoli and the surrounding capillaries because the lungs alveoli have low oxygen and high carbon dioxide

Yogita Ingle 5 years, 8 months ago

Alveoli are covered with blood capillaries so that the exchange of gases can take place between the membranes of the alveoli and the surrounding capillaries. The blood capillaries covering alveoli have a low oxygen and high carbon dioxide concentrations. This allows oxygen to diffuse into the blood and carbon dioxide to diffuse out of the blood.

Rings of cartilage are present in the throat as it helps the throat from collapsing when there is a low amount of air present.

It also helps them to expand when food or water passes through it.

Thus it plays an important role in supporting the throat during air blockage and helps in smooth air flow.

Fine hair and mucus act as the first line of defense in the nasal passage. They keep foreign particles that could cause illness from entering the body. The hairs (cilia) and mucus along the nasal cavity are responsible for trapping dust and other particles in the air you inhale and sweeping it out again

The cartilage provides support to the trachea which does not collapse even when there is less air in it.

The trachea or the windpipe is a cartilaginous cylinder that interfaces the pharynx and larynx to the lungs, permitting the entry of air, as is available in practically all air-breathing creatures with lungs.

The trachea reaches out from the larynx and branches into the two essential bronchi.  At the top of the trachea, a completed ring of cartilage is located, which protects it from getting damaged or collapsed when the flow of air is inadequate.

diffusion can not meet the requirement of multicellular organism like us because every cell is not exposed to oxygen containing environment.in our body there are millions of cells. in order to pass through diffusion it has to pass through all the cells and estimated about 3 yrs for oxygen to reach toes through diffusion. So multicellular organism have transport system which transport oxygen all cells within a minute....

The trachea or the windpipe connects the pharynx and larynx to our lungs.

This allows air to pass in and out of the lungs.

As the trachea is made of cartilaginous rings which are of C shape, it prevents the air passage not to collapse when we breathe out air.
