Biology



Biology is the natural science that involves the study of life and living organisms, including their physical structure, chemical composition, function, development and evolution. Modern biology is a vast field, composed of many branches. Despite the broad scope and the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation of new species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis. See glossary of biology.

Sub-disciplines of biology are defined by the scale at which life is studied, the kinds of organisms studied, and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions among biological molecules; cellular biology examines the basic building-block of all life, the cell; physiology examines the physical and chemical functions of tissues, organs, and organ systems; ecology examines how organisms interact in their environment; and evolutionary biology examines the processes that produced the diversity of life.

Meet Your Interstitium, A Newfound Organ   NBC - March 27, 2018

Scientists have stumbled on a previously unknown organ - one of the biggest in the human body and one that could significantly advance our understanding of cancer and many other diseases. Interstitium is a network of tissues and fluid filled compartments found just below the skin and in your digestive, urinary and respiratory systems. Studying that can help diagnose and track the areas of cancers and disease throughout the body




Interstitium: A Newfound Organ in the Human Body   Live Science - March 27, 2018
With all that's known about human anatomy, you wouldn't expect doctors to discover a new body part in this day and age. But now, researchers say they've done just that: They've found a network of fluid-filled spaces in tissue that hadn't been seen before. These fluid-filled spaces were discovered in connective tissues all over the body, including below the skin's surface; lining the digestive tract, lungs and urinary systems; and surrounding muscles, according to a new study detailing the findings
