Technical Tuesday Cells
Today I’m talking about all those cells
that make up your body. Cells are the smallest living units that are capable of
reproducing themselves, and your body is made up of many different kinds of
cells. The human body has about 200 different types of cells, and within these
cells there are about 20 different types of structures (organelles). Wow.
Every minute a human adult loses about
96 million cells. But take heart! They are all replaced. Whew. Cells have
different life spans – for example, white blood cells live about 13 days, while
cells in the liver live about 18 months.
Here is where it gets really
interesting: Cells in the inner lens of the eye, muscle cells of the
heart, and the neurons of the cerebral cortex are the only cells that will
be with you your entire life.
Pretty cool,
huh?
From the Big
Blue Book of Ballet Secrets
Anatomical Secret #26oo:
“Cells in the inner lens of
the eye, muscle cells of the heart, and the neurons of the cerebral cortex are
the only cells that will be with you your entire life.”
