Biology is a branch of life science — which is itself part of the branch of natural science— that focuses on the study of all types of life and living organisms. It is concerned with everything that involves a life form— including its structure, behavior, origin, growth, and reproduction, no matter how small or how large.

ICSE Class 10 Biology itself branches out into many different areas, each affecting somehow the human race. Every branch of biology— whether it's botany, marine biology, or even musicology just to name a few — helps scientists to help the human race live healthier and more productive lives.

Scientists and doctors would be hard-pressed without biology to help people fight off and treat illnesses. Pharmacology — the medicinal branch of biology— study the effects on the human body of all medicinal types.

Virology (viral disease study), pathology (assists in diagnosing disease and determines cause), and immunology (immune system studies) all work together to study the countless threats to our body. Besides, the knowledge gained from these studies further edifies the above-mentioned pharmacology studies in the treatment, prevention, and cure of disease— for example, hepatitis C.

ICSE Class 10 Biology gives us knowledge about how our body works, and what we can do to help it run effectively. Whether someone needs to lose weight, avoid hypertension or fuel their body for exercise, nutritionists can determine a suitable diet. It would be guesswork without biochemistry–the branch of science that studies how the body breaks down nutrients, fats, proteins, and carbs.

Physiologists are studying how muscles work and the causes of muscle stress, and how people use oxygen during physical motion. They plunge deep into dehydration studies to ensure proper hydration of athletes— both professional and weekend warriors."
