Enhance Your Biology Knowledge in Kajang

Physiology, a sub-discipline of biology, often gets confused with other branches of science. It is because physiology sounds like physics or even psychology when you say it. 

Many people are aware that physiology has something to do with the body. However, how is it distinct from anatomy? Anatomist studies the body's structure, while physiologist focuses on the body's function, understanding how different parts such as the heart, kidneys and liver work.

One of the most crucial parts of physiology is neuroscience. It studies how our brain and sense organs work. This doesn’t mean that physiologists focus only on individual organs in isolation. They have to look at the overall picture as all different parts have to come together to overcome challenges.

A sports physiologist will aim to determine how to improve our performance in athletic events. In contrast, a plant physiologist will focus on increasing crop yields to cope with the growing population.

Physiologists aim to understand how the body works. Therefore, they bring anatomy, physics, and chemistry together and apply them to the big question of how we do everything we do.

Exploring the Physiological Responses to Stress and Their Impacts on Health

In this fast-paced world, stress is inevitable in everyone’s life. Whether you are rushing to meet a deadline, worried about finances, or facing something problematic, our bodies initiate a complex chain of reactions designed to protect us. However, if you are constantly stressed, it can have a negative impact on your health.

The sympathetic nervous system plays a significant role in the body’s stress response, which triggers the fight or flight response. What happens internally in your body when you are stressed? First, the stress hormones adrenaline and cortisol are released as the brain's amygdala signals the hypothalamus. Your body will prepare for action where an increase in heart rate and blood pressure will occur. Cortisol, known as the stress hormone, helps regulate various processes like metabolism and immune response.

Physiologically, stress can cause some immediate changes that help us. For example, when our heart rate and blood pressure increase to deliver more oxygen and nutrients to our muscles, it prepares them for action. We also release glucose into our bloodstream to give us energy. But at the same time, non-essential functions like digestion and our immune system take a little break. These reactions are helpful when we face short-term stress, helping us respond quickly.

However, if stress becomes chronic, it can hurt us differently. When our cortisol levels stay high for a long time due to ongoing stress, our immune system can weaken, making us more prone to getting sick. Chronic stress can also mess with our sleep mood and even contribute to health issues like high blood pressure, heart disease, and obesity.

It's essential to understand how stress affects our bodies. Luckily, there are ways we can manage it and lessen its impact. Trying things like exercise, meditation, mindfulness, and having support from friends and family can help. Plus, doing things we enjoy, getting enough sleep, and eating a balanced diet are vital in managing stress.
