Human Organs

Your comprehensive resource on human organs, their anatomy, function and diseases and conditions that affect each and every organ in the human body.

Human organs and circulatory system.A number of human organs and the major parts of our circulatory system.

A knowledge of what our organs are like and does, is important if we must understand what happens when we are well as well as during illness.

The design, structure and function of the human body remains one of the most amazing and thought provoking concepts in the universe. The human brain has been aptly described as the greatest marvel known to man, because it is the only entity in the known universe that always seeks to understand itself.

The intricacy of the human eyes, heart, liver, kidneys and other organs and systems and how they work in unison for a common purpose, speaks of the presence of a deliberate grand designer as well as a surpassing intelligence and attention to detail that must have gone into our design. No wonder a well-known poet wrote “In a fear-inspiring way, I am wonderfully made”.

But what is an organ and how many organs are there in the human body?

Similar groups of cells come together to form a tissue. The cells that make up tissues do not only look alike, but have similar functions. There are four basic tissue types in the body. They are:

  • Epithelium tissue - these are the single layer of cells that line our skin, throat, bowels and internal organs
  • Connective tissue - these are the turf, fibers and support systems that are found in organs and body systems
  • Muscle tissue - there are two types of muscles in the human body - smooth muscles and skeletal muscles
  • Nerve tissue. 

All organs are made up of a combination of one or more of these four tissue types. Yes. Every single organ on the list of the 78 human organs are derived from one or more of these tissues.

Infection, injuries, or any other form of abnormality affecting any of these organs could lead to disease conditions in our body.

Here at, we bring you a wealth of information on all human organs and their functions as well as brief consideration of diseases and conditions that could arise from each of these  organs.
