Facts You Probably Didn't Know About Human Blood

Blood is a fascinating living body fluid, as its very presence is essential for human life. This thicker-than-water substance vitally transports oxygen and other essential nutrients throughout the body, regulates temperature, keeps internal chemicals balanced, and defends against harmful pathogens.

We all know that blood is red in color and that we need it to survive in this world. But what else do you know about this life-giving liquid? There’s more to it than meets the eye. Read on for a few interesting facts you probably didn’t know about human blood.

Blood Is Both a Liquid and a Solid

Blood is a liquid tissue. It’s the only liquid connective tissue in the living human body. This unique substance contains numerous cellular components, including red blood cells, white blood cells, platelets, and an extracellular matrix known as plasma. The plasma portion of blood makes up more than half of it, while the other elements complete the remainder.

When tissue tears or becomes damaged, the substance becomes solid as it clots, similar to other connective tissues. How so? The platelets stick to any open wounds. Then, the plasma proteins form a mesh-like closure around the injury site to prevent further blood loss.

There Are Trace Elements of Gold in Your Blood

This critical liquid tissue contains a variety of metal atoms, such as iron, zinc, lead, chromium, manganese, and copper. Yet, you may be surprised to find out about another metal element flowing through your bloodstream.

One of the facts you probably didn’t know about human blood is that it contains a tiny amount of gold. The trace amount of this element typically concentrates in regions surrounding the heart. Scientists have previously noted that this gold may serve a purpose by transmitting electrical signals throughout the body.

Daily Blood Volume Oscillates

Did you know that the blood volume within an individual’s body changes over a 24-hour timeframe? Your body has the highest volume before lunchtime. That said, the average volume for an adult is around 5 liters.

Curious about the relationship between blood volume and blood flow? The circulatory system in the human body is incredible, yet changes in blood volume can affect arterial pressure. This blood pressure impacts the proper flow of blood from one side of a vessel to another. Numerous factors can influence these blood movement dynamics and lead to poor circulation. Knowing more about the underlying factors and how your body works together is critical for maintaining comprehensive health and well-being.
