3. Human Physiology

Human Physiology is one of the fundamental pillars in the study of Physiotherapy. It is the science that studies the functioning of the human body and how its systems and organs work together to keep the body functioning efficiently and healthily. For a physiotherapist, it is essential to understand human physiology to be able to properly assess and treat their patients.

To begin, let's look at the musculoskeletal system, which is of particular interest to physiotherapists. This system is made up of bones, muscles, cartilage, tendons, ligaments and other structures that allow the human body to move and maintain its shape. The physiology of the musculoskeletal system involves the study of how muscles contract to produce movement, how bones and joints support the weight of the body, and how different components of the system work together to allow a wide range of movement.

Next, we have the nervous system, which controls and coordinates all body functions. It is divided into the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes all the nerves that branch from the spinal cord and extend throughout the body. The physiology of the nervous system involves the study of how neurons transmit electrical signals, how the brain processes these signals to produce thoughts, emotions, and behaviors, and how the nervous system controls the functioning of the body's other systems.

The cardiovascular system is another vital system that physical therapists need to understand. This system is made up of the heart, blood and blood vessels, and its main function is to transport oxygen, nutrients and other essential substances to all parts of the body. The physiology of the cardiovascular system involves the study of how the heart pumps blood, how blood vessels control blood flow, and how blood carries oxygen and nutrients to cells and removes waste products from them.

Last but not least, we have the respiratory system, which is responsible for the exchange of gases between the body and the environment. This system is made up of the lungs, airways, respiratory muscles and other structures that work together to allow us to breathe. The physiology of the respiratory system involves the study of how air enters and leaves the lungs, how oxygen is extracted from the air and transported to the blood, and how carbon dioxide is removed from the body.

In summary, Human Physiology is a vast and complex field of study, but it is absolutely essential for any physiotherapist. By understanding how the body's different systems work and interact, physical therapists can more effectively assess and treat their patients, helping them improve their mobility, reduce pain, and improve their quality of life.
