PART B_2

More than 50 million people die worldwide due to diseases that are left undetected. There are various medical screening tests available. Do you know people’s health could be revealed by breath analyzers? The human breath is composed of hundreds of components, which are called volatile compounds. These components are released every time a person exhales. By doing breath analysis using sensors, these volatile organic compounds in people’s breath could be analyzed to detect certain diseases in their early stages.
The technological advancement of breath analyzers has two major benefits. First, the breath analyzer could be integrated into a small handheld device, which could be used to test people in various settings in a noninvasive and simple way. So, a visit to the doctor would not be required. An example of this is the alcohol breath tester, which is being used by police officers to check the level of alcohol in a person’s breath. It could be used anytime and anywhere.
Second, the breath analyzer could be used to screen for many diseases at the same time. For example, cancer and diabetes could be detected at the same time instead of doing two different tests, which are usually more expensive and require more screening time, which makes diseases worse.

Please read aloud the lecture below.

PART C_2

The average human body is composed of 55 to 60% water, which regulates body temperature, lubricates the joints, and nourishes the brain. People lose two to three liters of water every day through normal body functions such as breathing, urinating, bowel movements, and sweating, so it is important for the human body to compensate for the lost fluid. Maintaining a balanced water level in the body is important. Drinking eight glasses of water a day is the conventional way, according to experts. But do you know that drinking a very small amount or too much water could harm the human body?
If the water level in a human body is not balanced, it could lead to two conditions. First, let us talk about dehydration, which means low water levels in the human body caused by not enough consumption of fluids. The human body could detect this through the brain’s hypothalamus, where the sensory receptors signal the release of anti-diuretic hormones. Once the hormones reach the kidneys, they are triggered to retain more water, which causes dark and concentrated urine. Some examples of the physical effects of dehydration are a drop in skin moisture and signs of cognitive impairment.
The second condition is called overhydration, which is caused by consuming too much water in a very short time. The brain being overhydrated slows down or even stops the release of anti-diuretic hormones into the blood, which causes cells to swell. Some examples of the physical effects caused by overhydration are vomiting and headaches, which happen during water intoxication.
