Fisiología

Fisiología, or physiology, is the branch of biology that studies how the body's systems function to keep us alive and healthy. It explains processes like how the heart pumps blood, how the lungs exchange oxygen, how nerves communicate, and how hormones regulate body activities. Essentially, physiology looks at the biological functions that make our bodies work smoothly, from cellular activities to complex organ interactions. Understanding physiology helps us grasp how our body maintains balance, reacts to changes, and adapts to different conditions, providing a foundation for medical science and health sciences.
