The first time a pathogen hits, our bodies do not know how to handle it properly. This means that our bodies take more time to handle it the first time around. The second time around, however, our bodies have altered so that they can handle the pathogen more efficiently. Hope this helps!

A. Oxygen, this is why it is very important to keep breathing while exercising.
Alveoli is the smallest part of the respiratory system. The best description about it is “they are the smallest tubes in the respiratory system”.
EXPLANATION
Alveoli’s function is to exchange oxygen and carbon dioxide. Thus, it becomes an important part of the respiratory system. Alveoli’s shape is like tiny balloon-shaped. Its location is at the very end of the respiratory tree. It is arranged in clusters which are throughout the human’s lungs. Alveoli also can be said as the endpoint of the respiratory system. Without alveoli, a human cannot breathe normally.
Due to the important function of alveoli, here are some medical conditions that people have to be aware of:
• Emphysema
• Pneumonia
• Tuberculosis
• Bronchioloalveolar carcinoma
• Acute respiratory distress syndrome
• Respiratory distress syndrome
• Pulmonary edema
We also have to be aware of the effect of tobacco and smoking because these things can affect the function of alveoli. Tobacco and smoking cause the damage, right down to the molecular level. It will disrupt our body’s ability to repair itself. In a serious condition, it will lead to an infection or trauma. The effect of tobacco and smoking also cause a risk to human’s lungs. The damage of the alveoli will cause human’s lungs exposed to the toxic fumes.

Schachter-Singer two-factor theory
Explanation:
A polygraph is a lie-detector test which uses certain devices and procedure to measure or record various physiological parameters like blood pressure, heart rate, respiratory rate, skin conductivity etc at the same time when the subjective person answers to a series of questions asked.
The principle is that a person’s or examinee’s physiological or clinical parameters like blood pressure or heart rate can accelerate, stay stable, or may even go down in response to the questions asked. Depending upon these changes, the examinee can be assessed whether he/she is telling a lie or truth about something asked.
The Schachter-Singer two-factor theory of emotions states that emotions are dependent on two factors – physiological arousal and cognitive label.
According to this, an environmental stimulus gives rise to a physiological reaction or arousal which then leads to cognitive appraisal of the emotion.
Thus the theory of polygraph is based on Schachter-Singer’s emotional theory.
