1. A Liver-Shaped Valentine

From some angles, in shape and color the liver looks a lot more like a valentine than the heart does.

The liver is a soft dark-red organ lying mostly on the right side of the abdomen between the stomach and diaphragm.

Roughly football-size, the liver weighs about 3 pounds and is the largest internal organ of the body. It’s the only one that can regenerate itself—25% is enough to regenerate an entire liver.

The liver is a crucial intermediary between the heart, lungs, and digestive system. Blood enters the liver through an artery carrying oxygen-rich blood and through a vein carrying nutrient-rich blood from the small intestine. These blood vessels repeatedly subdivide in the liver, eventually becoming an intricate network of microscopic capillaries. Liver cells process each droplet of blood, constantly monitoring and adjusting blood conditions.

Liver cells metabolize proteins and carbohydrates, converting the excess into fat. The liver makes bile to digest fats, regulates fat storage, and produces 80% of the body’s cholesterol. The liver removes excess sugar from the blood, converts it to starch, and stores it. When quick energy is needed, it converts the starch back to sugar and releases it into the blood.

Liver interior view

The liver builds amino acids and assembles them into proteins, manufacturing more proteins than any other organ. It also manufactures vitamins and hormones and helps maintain hormone balances. The liver stores important vitamins and minerals, including iron used to produce hemoglobin, the oxygen-carrying molecule of the blood.

Polar bears store so much vitamin A that their livers are lethal to humans. Eating one to three ounces of polar bear liver will kill you, as some North Pole explorers have discovered.

The liver manufactures red blood cells during an embryo’s first trimester, gradually transferring most of this function to bone marrow by birth. The liver produces many essential blood proteins, and adds them to the blood as needed. This includes infection-fighting proteins, blood-flow and blood-clotting proteins, and most blood plasma proteins. One of the liver-manufactured blood proteins (serum albumin) regulates blood volume to help maintain proper blood pressure and prevents a digestive enzyme from also digesting proteins elsewhere in the body.

Are livers mentioned in the Bible?
How do you protect against APL syndrome, the most common and the most dangerous liver disease?

Read my February 2008 newspaper column:
A Four-Fold Valentine

For Thou didst form my inward parts. Thou didst weave me in my mother’s womb.
I will give thanks to Thee, for I am fearfully and wonderfully made.
Wonderful are Thy works, and my soul knows it very well.
My frame was not hidden from Thee, when I was made in secret,
and skillfully wrought in the depths of the earth.
Thine eyes have seen my unformed substance, and in Thy book they were all written, the days that were ordained for me, when as yet there was not one of them.
(Psalm 139:13-16)
