Do Wasps Have Blood?

Unlike humans, wasps do not have lungs, heart, or blood. Instead, they have a transparent liquid known as haemolymph. Haemolymph is used by wasps to clean their internal organs and supply nutrients.

Although not a common occurrence, it is possible for a person to develop an allergic reaction to wasp venom. Depending on the amount of venom inhaled, a person can experience significant pain. In addition, a person may develop neurological complications. These complications include stroke.

Stroke is a disorder that occurs when a blood clot travels up to the brain and blocks blood flow. Several reports have documented strokes after bee and wasp stings. If you’ve been stung by a wasp, it is important to get medical attention immediately. Symptoms include a swollen abdomen, weakness on one side of the body, difficulty speaking, and a rash.

In addition to stroke, wasp stings can cause atrial fibrillation, an irregular heartbeat. This is an abnormal rhythm that can cause trouble breathing and swelling of the lungs. Depending on your risk factors, you may be at a higher risk for stroke. Fortunately, most people who go into shock after a wasp sting do so quickly.

In order to reduce the pain and swelling of a wasp sting, you can apply a cold compress to the area. You can also use calamine lotion to soothe the skin.

If you develop a severe allergic reaction, you may need to take epinephrine, which can help to restore your blood pressure. You can buy “bee sting kits” that contain epinephrine injections. You can also receive venom immunotherapy.
