Interesting human cell facts you should know!


A cell, the tiniest section of your body, which is not even visible to the naked eye – what can be so interesting about it – you may wonder. But hey, after reading these facts about cells, you’ll know what even the tiniest cell in your body makes such a huge difference!

  1. Cells are very tiny; You cannot see them without a microscope – that’s something we’ve heard since we were growing up right? But hold on, there are exceptions here too – the nerve cells or neurons as they are known stretch from the tips of your toes to your hips – approximately one meter -quite huge, isn’t it?
  2. 300 billion cells are produced every day; this is to keep up with the 300 million cells dying every minute!
  3. Human cells have a membrane which holds all of its contents inside. And this membrane is not a mere sac – it is a membrane that has receptors to differentiate itself from other cells.
  4. Let’s hop into the cell to see what it contains – Endoplasmic reticulum, Golgi Apparatus, Mitochondria, Lysosomes, Microtubules, Microfilaments, Peroxisomes. Phew! And they say the cell is tiny!
  5. Cells also contain organelles, which are basically the kitchen of the cell. These organelles make proteins, process chemicals and generate energy for the cell – quite a recipe to keep the cells going!
  6. Cells together form tissues; these tissues together form organs – so basically the smallest unit of your heart is a cell.tissue
  7. It takes 60 seconds for blood cells to circulate through your body. In total ten years combined, a cell will have travelled over 96000 kilometres – that’s equivalent to 2.4 times of the earth’s circumference!
  8. Types of cells? Well, there are 20, and I bet you won’t be able to name all of them! Let’s try – Nerve cells, bone cells, Skin cells, Red blood cells, White blood cells…. some other cells…Told you!
  9. There are 23 pairs (46 in all) chromosomes in the human body. Chromosomes are inside the nucleus of the cell. The nucleus is inside the cell. The point I’m trying to put forth here is – if this is the case, imagine how tiny chromosomes are!
  10. How many cells do we actually have in our body? 37.2 trillion! Woah!
  11. Red blood cells have a lifespan of 120 days. Neurons live as long as you do. Skin cells have the least lifespan – only a few weeks!
