All organisms are made up of cells. Various chemicals reactions occur in living organisms that keep cells living. So in physiology, we deal with the functions and normal body mechanisms.
Physiology is the branch of biology that deals with the normal functions of living organisms and their parts.
Physiology is the science of studying the functional activities and mechanisms in the biological body.
Physiology is derived from two Greek words physis means nature
Logos means study.
Physiology can be divided into viral physiology, bacterial physiology, plant physiology, human physiology, and cellular physiology.
Viral physiology - viral physiology deals with the investigation of biological processes and activities of viruses.
Bacterial physiology - Bacterial physiology deals with the life-supporting functions of bacteria, which allow the bacterial cell to grow and reproduce.
Cellular physiology - deals with the study of physiological processes occurring within and among the cells and intracellular communication and behavior.
It is the science of how the human body functions in fitness and illness. It describes the chemistry and physics behind the basic body functions. It helps in knowing the basic body functions, and to find the treatment of disease. It helps us comprehend what occurs in a healthy body and normal life and what goes on when someone gets sick.
Human physiology can be divided into various types.
Cell physiology - This is the main field of human physiology, in which we study the functions of cells.
Special physiology - in this branch of physiology we study the functions of specific organs
Systemic physiology - deals with the functions of the body system such as cardiovascular physiology, respiratory physiology
Pathophysiology - deals with the study of the effects of disease on the human body or the organ system.
The main systems covered in human physiology are as given below-
Endocrine system - This system includes endocrine glands and hormones which carry messages from one body part to another.
The pituitary, thyroid, adrenal, hypothalamus, parathyroid, and pancreas are the main endocrine glands in the human body.
Digestive Systems - Digestive systems start from the mouth and up to the anus. It also includes the liver, pancreas, and spleen.
Integumentary system - This system includes skin, nails, hairs, sweat glands, and sebaceous glands.
Renal/ urinary system - this system includes the kidney, ureters, and bladder.
There are various branches of physiology:
Physiologists are medical professionals who study the human body and how organs and organ systems work together under abnormal and normal conditions.
There are various types of physiologists depending on the field of specialization.
One of the largest organs in the body is the skin
Skin revives itself after 28 days
The human brain provides to 2%of total weight
Each day the human heart pumps approximately 71 liters of blood
The rhythm of the heart is controlled by electrical impulses.
1. What is an example of physiology?
Ans: Human physiology is the branch of physiology that deals with the study of humans. It deals with the activities and functions of living matter.
2. What are the topics of physiology?
Ans: There are various topics in physiology
Body and fluids
What are different systems in the body?
What is the physiology of the human body?
Who is the father of physiology?
Why is physiology important?
What is a physiology test?
Physiology is the study of normal and abnormal functions and mechanisms of the human body.
There are various types of branches and fields of physiology.
Branches of Physiology are according to the biological system
Physiologists are the persons who deal with physiology.
1. Why is physiology so important?
Physiology is very important for us because
It is the foundation of life on which we build our knowledge about
how to treat disease
How to cope with stresses
How to deal with the various abnormalities of our body
Physiology is a practical scientific profession and it is of core importance to medicine and health sciences. It provides a thorough understanding of normal body functions and allows for more effective treatment of abnormalities and diseases. It is useful to know the basic principles of body functions.
2. What are the five key themes of physiology?
The five key themes of physiology are as given below:
Homeostasis and regulation- homeostasis is maintaining a constant internal body temperature.
Structure and function relationships- this study is about the relation of anatomic structure with their functions.
Compartmentation- is defined as the way organelles are present in the eukaryotic cells.
Biological energy and transformation- the process of converting one form of energy to another form.
Communication and information flow - the process of transferring the message takes place through chemicals.
3. What are the two major goals of physiology?
There are many goals of physiology. But the two major goals are:
To understand and anticipate the response of human beings or may organisms to a particular stimuli
To understand homeostasis which is the constant maintenance of the internal body environment in presence of a constantly changing external environment, such as maintenance of constant body temperature in Antarctica as well as in any deserted area
