Do Bees Have Blood?

We all know how hard honey bees work. Within a four-mile radius of their colony, they hunt for food. They can fly at speeds of up to 15 miles per hour, and their wings can beat 200 times per second, or 12,000 times per minute. With all these enormous efforts, we can’t help but wonder what fuels these buzzy little creatures.

However, do bees even have blood to begin with? Nope, honey bees don’t have blood, but they do have several other systems that function like our circulatory system does. 

So how does their body work? Let’s take a look at bee anatomy and physiology to find out!

Do bees have blood?

The answer to the question, “Do bees have blood?” is no. Bees do not have blood because they do not have a circulatory system. They are also missing other vital parts of the human body, including the brain and nervous system, which means that bee brains are different from those of humans.

Bees’ digestive systems function similarly to humans, but there is one difference: honey bees eat pollen grains, which can’t be digested in their stomachs like meat can be digested in ours. Instead, pollen grains pass through the gut (or alimentary canal) and into food sacs called caeca where they are excreted as waste material during defecation or regurgitation (a process called vomiting). 

This isn’t an issue for bees because they aren’t eating much at once; usually just enough to fill their crop—a pouch located inside a bee’s head that stores food until it needs it later on during digestion—and then some more just in case there might be an emergency situation where food supplies run low later on down the road!

Honey bee anatomy and physiology

A honey bee has a circulatory system just like we do. However, it’s quite different from our own.

The honey bee heart is a pulsatile pump with no valves or chambers and can only pump forward (in the direction of travel). That’s why if you see what looks like blood coming out of a stinger wound on your hand, it will be in pulses that stop as soon as you pull away from the bee. The blood vessels themselves are open and not made out of cells like ours are; they’re more similar to those found in other invertebrates.

The bee’s powerhouse systems: heart, muscle, and nerve cells

Bees have a closed circulatory system, which means the blood does not mix with the tissues and organs of the body. The heart is located in the center of their abdomen, along with two pairs of ovaries, two pairs of testes (one pair for each male bee), one kidney, and other internal organs.

The bee’s heart is a large muscle that pumps blood through its body using its own unique rhythm, or “beat.” It has four chambers where deoxygenated blood collects before being pumped out by muscles surrounding each chamber to be re-oxygenated and then returned to the body via tubes called arteries, which carry oxygen throughout your body via red blood cells traveling through them at speeds reaching up to 60 km per hour!

In humans, we have a similar system but our hearts pump about 1 liter per minute, but in bees, it can reach 5 liters! This means that bees need far more oxygen than humans do, so they must collect more when they live outside since there isn’t enough the air alone; this is why they often congregate around flowers during periods when pollen collection takes place (which also helps pollination).

Can honey bees pump blood?

Since we have recently learned that honey bees do not have blood, they have a good substitute for it. Bees have an outside system made up of a network of tubes that connect to each other and carry food and other things.

Invertebrates include things like bees, ants, and other insects; unlike us, these creatures do not have backbones (vertebrae). Their bodily organs and tissues, in contrast to those of our vertebrates, are structured in such a way that they are able to be packed into an area that is far smaller than the one that ours might occupy.

Insects are able to squeeze their bodies into small spaces, which helps them when they are searching for food or constructing their houses. It also means that their circulatory systems aren’t quite as complicated as ours are.

The special fueling power of bees

While you may see a bee’s body covered in red, that isn’t blood. Instead of having blood, bees have a fluid called hemolymph. Hemolymph is actually more similar to the human lymph system than it is to human blood.

The honeybee circulatory system is quite like our own in that it is made up of tubes that transport oxygen and nutrients throughout the body. However, there are some important distinctions between our systems, and it is precisely these distinctions that allow bees to achieve such remarkable feats of flight.

The circulatory system of a bee is not nearly as complicated as the circulatory system of a person. The main difference between a bee’s circulatory system and ours is that bees don’t have veins and arteries. They have something called the aorta (pronounced “or-tay”), which is a large tube that makes this process possible.

This tube may be seen running all the way from the top of their bodies to the bottom of their bodies. After completing its journey around the bee’s body, the hemolymph makes its way via this tube and finally returns to its original location.


So, we’ve learned that bees do not have blood. This is because their bodies are filled with hemolymph, an extracellular fluid that lacks hemoglobin and red blood cells. Hemolymph does not flow inside vessels but rather in the extracellular space.

That said, we can all agree that bees are wonderful creatures with incomparable work grades. Thanks to their extracellular system, bees can do all the jobs they need to do every single day!
