What is Physiology?
The branch of biology dealing with the functions and activities of living organisms and their parts, including all physical and chemical processes.
On the other hand Homeopathy is a natural treatment system. Its basic concept is “Similia Similibus curentur”. It means likes cure likes.
Physiology is the science of life. It is the branch of biology that aims to understand the mechanisms of living things, from the basis of cell function at the ionic (আয়নিক) and molecular level to the integrated behavior of the whole body and the influence of the external environment.
চিকিৎসা বিজ্ঞানের যে শাস্ত্র পাঠ করলে মানব দেহের বিভিন্ন অঙ্গ প্রতঙ্গের কার্যাবলী সম্পর্কে জ্ঞান লাভ করা যায় তাকে Physiology বলে।
Physiology শব্দটি এসেছে দুটি গ্রীক শব্দ physis that means nature এবং logia that means study. শব্দটি সর্বপ্রথম ব্যবহার করেন John Furnel.
Father of physiology বলা হয় Hippocrates কে। Experimental physiology র জনক বলা হয় Gallen কে।
Cellular physiology is the branch of physiology which deals with the natural function and phenomena of live cell.
Research in physiology helps us to understand how the body works in health and how it responds and adapts to the challenges of everyday life.
It also helps us to determine what goes wrong in disease, facilitating the development of new treatments and guidelines for maintaining human and animal health.
The emphasis on integrating molecular, cellular, systems and whole body function is what distinguishes physiology from the other life sciences.
ফিজিওলজি বা শারীরতত্ত্ব হচ্ছে জীবিত প্রাণিসমুহের স্বাভাবিক জীবন ক্রিয়া সংক্রান্ত বিজ্ঞান। ফিজিওলজির জীবিত প্রাণিসমুহের কোষ, টিস্যু, অঙ্গ, তন্ত্র ইত্যাদির স্বাভাবিক ক্রিয়া নিয়ে আলোচনা করা।
কিন্তু মৃত কোষ, টিস্যু, অঙ্গ, তন্ত্র ইত্যাদি হলে তখন আর তা শারীরতত্ত্ব থাকে না তখন সেটাকে বলা হয় Pathology।

Physiology is the study of how living organism work. Physiologist are interested in function and integration-how parts of the body work together at various levels of organization and, most importantly, in the entire organism.
The human body is organized into cells, tissues, organs, and organ systems.
What is Anatomy and physiology?
Anatomy and physiology are two of the most basic terms and areas of study in the life sciences. Anatomy refers to the internal and external structures of the body and their physical relationships, whereas physiology refers to the study of the functions of those structures.
What is human physiology?
Human physiology is the branch of medical science which deals with the study of normal functions of living body and its parts with their principal mechanism and control.
In short human body physiology is the study of the processes and function of the human body.

Importance of studying human physiology.
Physiology is the second part of Medical science study. Without it none can achieve a sound knowledge in medical science. Some example in favor of physiology study.
- To treat a human being should known about function of human body. Physiology discusses with the function of human body.
- If normal function is known then abnormality can be pointed.
- If a organ shows abnormal sign or symptom then to know about mechanism of origin of sign or symptom normal function of the organ should be known. Only studying physiology it can be achieved.
- To diagnose diseases laboratory investigation may required, Physiology can focus on the required investigation.
- To understand the mechanism of action of drug physiology is essential.
Physiological Systems
A system is a group of organ or tissues acts for a common goal.
When some organ or tissues functioning similar then together these are known as physiological system.
The body maintains its function by the help of some physiological systems (which are controlled by nervous and hormonal regulation).
- Nervous system _ Co-ordination of function of different parts of the body.
- Endocrine system _ Maintain function of different part of the body.
- Respiratory system _ Respiration.
- Cardiovascular system _ Blood circulation.
- Lymphatic system _ Lymph circulation and immunity.
- Digestive system _ Digestion and absorption.
- Hepatobiliary system _ Secretion of bile.
- Urinary system _ Production and excretion of urine.
- Reproductive system _ Reproduction.
- Musculoskeletal system _ Movement of the body.
