Class 12 Biology Chapter 7 Human Health and Diseases: Important Topics

The term health has been a topic of discussion from the beginning of humanity. The early Greeks like Hippocrates and the principles of Ayurveda stated that health is a state of body and mind in balance. Some of the important topics that are covered in this chapter are:

Health and Disease

The World Health Organization (WHO) defines health as a condition of one's physical, mental, and social well-being. Conversely, disease is an impediment to our body's health that interferes with the way our organs and systems work. Thus, the condition of total well-being may be seen as the link between health and sickness. 

Cancer

Uncontrolled cell division leading to tumor growth is the cause of cancer. When normal cells undergo oncogenic transformation, regulatory systems fall down. The ability to stop other cells from growing when they come into touch with one another is absent from cancerous cells. 

HIV and AIDS 

HIV, or the Human Immunodeficiency Virus, is a retrovirus with RNA as its genome that causes AIDS. Viral DNA is produced in the host by the enzyme reverse transcriptase. Multiple virus copies are created when the viral DNA is integrated into the host genome.  

Vaccines

One way to think of a vaccine as a biological preparation for acquiring protection against a certain illness is through vaccination. Usually, the disease-causing agent, its surface proteins, or its toxins are present in vaccinations in a weakened or dead form.
