ANATOMY

Anatomy is a science which is directly associated with biology and medicine that studies about identification and description about human body. Extracting from the basics, Anatomy comes up from the Greek words “ana” means “up” and “tome” means “cutting” which explains that back in the time, cutting up or dissection of a body was needed to study about it. But now that we have advanced imaging technology, it is much easier to study about a human body in a much precise manner with no dissection or cutting needed.

Here with Earth’s Lab, you’ll have a wide range of detailed and accurate information about the anatomical structures, even the minute ones existing in a human body. With our closely prepared interactive human body interface and detailed research on every topic, we have tried to make your learning experience better and you will be updated with latest studies carried out all over the world to keep you a level up always.

PHYSIOLOGY

Physiology is the study of life questioning about the internal workings of organs and how they interact with the world around them. Being a branch of biology, it is related to the function of organs and organ systems and how they work within the body to respond to challenges. From genetics to psychology, physiology has something to say about every aspect of life.

With Earth’s lab, you will unlock different levels of organisation of organs present in an organism like the digestive system and the respiratory system. Our user-friendly interface will make it easier for you to explore the different organs and their mechanisms. Our researched study for the smallest of the organs will inch you ahead of the rest in terms of the informative data about the organs, their working and their application.
