This A to Z Challenge post is brought to you by the letter “K”

A to Z Challenge

I am so excited to take part in this, my second, A – Z Challenge!  Last year I did the challenge using “recipes” as my inspiration.  Well, this year I’m going to draw on my nursing background and use “parts of the human body” as my inspiration!  Hmmm…a part of the body that starts with “Q”, “X” or “Z”….

It should be a lot of fun and I’m looking forward to seeing how everyone interprets the Challenge!

This was a bit of a tough one as there really are only a couple parts of the human body that begin with the “letter “J”…so, without further ado, “K” is for : Kidneys

Photo is from Google files

The kidneys are bean-shaped organs, each about the size of your fist.

They are located near the middle of the back, just below the rib cage, one on each side of the spine.

Every day, a person’s kidneys process about 200 quarts of blood to filter out approximately 2 litres of waste products and extra water.

The kidneys remove wastes and water from the blood to form urine.  Urine flows from the kidneys to the bladder through the ureters.

Wastes in the blood come from the normal breakdown of active tissues, such as muscles, and from food. The body uses food for energy and self-repairs. After the body has taken what it needs from food, wastes are sent to the blood. If the kidneys did not remove them, these wastes would build up in the blood and damage the body.

K is also for:

keratin  An insoluble protein present in the epidermis and in epidermal derivatives, such as hair and nails

ketone bodies  The substances derived from fatty acids via acetyl coenzyme A in the liver; namely, acetone, acetoacetic acid, and b-hydroxybutyric acid. Ketone bodies are oxidized by skeletal muscles for energy.

knee A region in the lower extremity between the thigh and the leg that contains a synovial hinge joint.

Kupffer cells  Phagocytic cells lining the sinusoids of the liver that are part of the body immunity system.

I found the above definitions  at the McGraw-Hill Applied Biology Resource Center.  Visit their site and you’ll find a few more “K” parts of the body listed there!

  1. I’d never heard of Kupffer cells before….learning new things all the time. Thanks for posting the great K body parts.

    Hi Monica – I haven’t been posting but enjoy soooo much reading all your info on the human body. Your blog is great.

  3. Monica, I had planned what I was going to comment, but now see Kathy at Oak Lawn Images has said it for me. 25 years of nursing and never heard of Kupffer cells!!
    Well done and keep the body parts rolling!!!
    Patricia, Sugar & Spice & All Things ? Nice

  4. Thanks Pat and I’ll be keeping those body parts rolling…well at lest until I get to “Q” and “X”…lol

  5. Great information! Love biology info.
