FAQs on Flashcards: Human Health & Diseases - Biology Class 12 - NEET

1. What are the common types of diseases that affect the human body?
Ans. There are several common types of diseases that can affect the human body, including infectious diseases (such as flu or tuberculosis), chronic diseases (such as diabetes or heart disease), autoimmune diseases (such as rheumatoid arthritis or lupus), genetic diseases (such as cystic fibrosis or sickle cell anemia), and mental health disorders (such as depression or anxiety).
2. How does the immune system protect the human body from diseases?
Ans. The immune system is responsible for protecting the human body from diseases. It consists of various organs, cells, and proteins that work together to defend against harmful pathogens, such as bacteria, viruses, and parasites. The immune system recognizes and destroys these pathogens through a complex process involving specialized cells called white blood cells, antibodies, and other defense mechanisms.
3. What are the risk factors for developing chronic diseases?
Ans. Several risk factors can increase the likelihood of developing chronic diseases. These include unhealthy lifestyle habits such as smoking, excessive alcohol consumption, poor diet, lack of physical activity, and obesity. Other risk factors include genetic predisposition, age, gender, environmental factors, and certain medical conditions. It is important to address these risk factors to prevent or manage chronic diseases effectively.
4. How can infectious diseases be prevented?
Ans. Infectious diseases can be prevented through various measures. Some of the key preventive strategies include practicing good hygiene, such as regular handwashing with soap and water, covering the mouth and nose while coughing or sneezing, and avoiding close contact with infected individuals. Vaccinations are also crucial in preventing many infectious diseases. Additionally, maintaining a strong immune system, avoiding risky behaviors, and following specific guidelines during disease outbreaks are essential preventive measures.
5. What are the common symptoms of mental health disorders?
Ans. Mental health disorders can present with a wide range of symptoms. Common symptoms include persistent feelings of sadness or hopelessness, changes in appetite or sleep patterns, loss of interest in activities once enjoyed, difficulty concentrating or making decisions, fatigue or low energy, irritability or anger, social withdrawal, and thoughts of self-harm or suicide. It is important to seek professional help if experiencing any of these symptoms to receive appropriate diagnosis and treatment.
