 Health Science for Saving Lives: The Role of Science in Human Life

What is the role of science in human life?

To survive, the greatest need of human beings is a healthy, strong, and disease-free body. However, in real life we cannot remain healthy all the time. At different times, we suffer from various diseases. When illness occurs, proper treatment is essential, and the first condition for proper treatment is accurate diagnosis. In the modern era, the healthcare system has advanced significantly. Through the application of various scientific theories and technologies, modern diagnostic instruments have been developed, making it possible to identify different health problems quickly and accurately. In particular, the application of physics has opened new horizons in medical science.

Can science save your life?

In the past, physicians diagnosed diseases by observing patients’ external signs and symptoms. In many cases, such diagnoses were inaccurate, and treatments were largely based on guesswork. With the invention of modern instruments, diagnosis has become not only precise but treatment has also become far more effective. Modern devices used in health science play a vital role in saving human lives.

What is the role of X-rays?

In 1895, the scientist Wilhelm Conrad Röntgen discovered a type of high-energy invisible radiation that could pass through human muscles and capture images of internal body structures. As its nature was unknown, it was named the X-ray. X-rays are essentially electromagnetic waves with much shorter wavelengths and much higher energy than visible light.

When a high voltage is applied between the cathode and anode in an X-ray tube, electrons strike the anode, producing X-rays. These rays can penetrate materials of different densities, allowing internal structures of the body to be visualized.

How do X-rays affect human health?

Detecting bone fractures, cracks, and dislocations

Identifying tooth decay and cavities

Diagnosing lung diseases such as tuberculosis, pneumonia, and cancer

Detecting kidney and gallbladder stones

Use in radiotherapy for cancer treatment

Since X-ray radiation can be harmful, necessary precautions are taken. X-rays are avoided in pregnant women, and other parts of the body are covered with lead aprons for protection.

What is the importance of ultrasonography?

Ultrasonography uses high-frequency sound waves (1–10 megahertz) to create images of internal organs. Sound waves produced by a device called a transducer enter the body and generate echoes, which are analyzed to produce a complete image.

Uses of ultrasonography:

Determining the structure and position of the fetus during pregnancy

Detecting uterine and pelvic tumors

Identifying gallstones, tumors, and heart defects

Examining the heart through echocardiography

Although it is safer than X-rays, prolonged continuous use is not recommended.

Role of CT Scan in Diagnosis

A CT scan (Computed Tomography) is a method that uses X-rays to create three-dimensional images of the body’s interior. An X-ray tube rotates around the patient, taking images from different angles, which are then analyzed by a computer to produce a clear image.

Uses of CT scan:

Diagnosing problems of the brain, lungs, and blood vessels

Determining the location and size of cancers and tumors

Detecting internal bleeding or vascular problems in the head

CT scans are not performed on pregnant women, and caution is taken when using contrast dyes.

What is the Importance of MRI

Most parts of the human body contain water, whose hydrogen protons respond to strong magnetic fields. Based on this principle, Magnetic Resonance Imaging (MRI) was developed. It uses magnetic fields and radio waves instead of X-rays.

MRI can produce extremely clear images of soft tissues, the brain, nerves, and the spinal cord.

What is the Working Principle of ECG

An ECG (Electrocardiogram) is a method used to record the electrical activity of the heart. It is extremely important for identifying normal and abnormal heart rhythms.

What is the ECG can detect:

* Abnormal heart rhythms

* Heart attacks

* Enlargement of the heart

ECG is widely used in routine health check-ups and before surgical procedures.

What Is the Endoscopy

Endoscopy is a procedure that allows direct visualization of hollow organs inside the body. By transmitting light through optical fibers, images of internal structures can be observed.

What is the Uses of endoscopy:

* Stomach and intestines

* Lungs

* Female reproductive organs

* Urinary tract and nasal cavity Through endoscopy, tissue samples can be collected and minor surgical procedures can also be performed.

Conclusion

From the above discussion, we learn how important health science is in human life. Thanks to modern medical instruments, even complex diseases can now be easily diagnosed and treated. Advances in health science have improved the quality of human life and are saving countless lives.
