What is an absence of respiration called?

We often confuse respiration with breathing. Breathing is a gas exchange process by which we take in oxygen with each inhale and release carbon dioxide with each exhale. This is a physical process which takes place continuously from the time of birth till the time of death. When this process is absent except at the time of death, it is regarded as APNOEA.

This is a physical process which takes place continuously from the time of birth till the time of death. When this process is absent except at the time of death, it is regarded as APNOEA.


Vertebrate animals living on land all have lungs so that when the muscle below our rib cage (called diaphragm) is pulled down, air gets sucked into our lungs and oxygen in the inhaled air is exchanged for carbon dioxide from our body which is then exhaled when the diaphragm bows upwards.


Respiration is a biochemical process by which all living things obtain energy by combining oxygen and glucose to form energy in the form of ATP, carbon dioxide and water. Oxygen obtained by vertebrate animals in the process of breathing is utilised in carrying out the biochemical process called respiration.

What is the meaning of "juggling fiends" in Macbeth?

Macbeth is beginning to realize that the three witches have been deceiving him since he first encountered them. Like jugglers, they have kept changing their forecasts in order create confusion. This is particularly apparent when the Second Apparition they raise in Act IV,   Scene 1 tells him that no man of woman born can overcome him in hand-to-hand battle--and then Macbeth finds himself confronted by the one man he has been avoiding out of a...

What are some external and internal conflicts that Montag has in Fahrenheit 451?

 Montag, the protagonist of Fahrenheit 451, faces both external and internal conflicts throughout the novel. Some examples of these conflicts are: External Conflicts: Conflict with the society: Montag lives in a society that prohibits books and critical thinking. He faces opposition from the government and the people who enforce this law. Montag struggles to come to terms with the fact that his society is based on censorship and control. Conflict with his wife: Montag's wife, Mildred, is completely absorbed in the shallow and meaningless entertainment provided by the government.

In A People's History of the United States, why does Howard Zinn feel that Wilson made a flimsy argument for entering World War I?

"War is the health of the state," the radical writer Randolph Bourne said, in the midst of the First World War. Indeed, as the nations of Europe went to war in 1914, the governments flourished, patriotism bloomed, class struggle was stilled, and young men died in frightful numbers on the battlefields-often for a hundred yards of land, a line of trenches. -- Chapter 14, Page 350, A People's History of the United States Howard Zinn outlines his arguments for why World War I was fought in the opening paragraph of Chapter 14 (referenced above). The nationalism that was created by the Great War benefited the elite political and financial leadership of the various countries involved. Socialism, which was gaining momentum in Europe, as was class struggle, took a backseat to mobilizing for war. Zinn believes that World War I was fought for the gain of the industrial capitalists of Europe in a competition for capital and resources. He states that humanity itself was punished by t...
