There is no single universally agreed number, but most modern anatomy sources say the human body has around 78 major organs , with some experts arguing for about 78–80 depending on what is counted as a distinct organ.

Quick Scoop: Why the number isn’t exact

Different medical groups define “organ” slightly differently, which changes the final count.

  • A common “standard list” gives 78 organs.
  • Some newer references say 78 to 80 because recently recognized structures (like the mesentery or interstitium) may be counted separately.
  • If you count each bone and tooth as its own organ, the total can jump into the hundreds (over 280).

So when people ask “how many organs are in the human body,” the usual simple answer is about 78 major organs , with a note that the exact count depends on the definition and method of counting.

Mini breakdown: vital vs other organs

Among those 78 or so organs, a small group are considered absolutely essential for survival.

  • Vital organs (you cannot live without these):
    • Brain
    • Heart
    • Liver
    • At least one lung
    • At least one kidney
  • Other major organs (important but not always strictly “vital” on their own):
    • Stomach, intestines, pancreas, spleen
* Thyroid, adrenal glands, pituitary and other endocrine glands

* Skin, bones, joints, blood vessels, reproductive organs, etc.

These work together in organ systems like the circulatory, respiratory, digestive, nervous and others (usually 11 main systems are listed).

Why this is a “trending topic”

Every few years, headlines pop up like “New organ discovered,” for example when structures such as the mesentery or the interstitium were proposed as organs. This keeps the question “how many organs are in the human body” alive in news, blogs, and forums, even though everyday teaching still uses the 78-organ figure.
