Do insects have blood in their bodies? Do insects really have blood

The blood of insects is a lymphoid fluid circulating in the body cavity, often called hemolymph, and is made up of plasma and blood cells. Except for a few insect species (e.g. midges larvae) whose blood is red due to heme content, most of them are slightly yellow, orange and blue-green. The amount of blood varies greatly depending on the species and state of the worm, and generally accounts for 15%-75% of the body volume of the worm.

Insect blood has the dual functions of mammalian blood and lymphatic fluid, so the circulatory system has transport and mechanical functions, storage and metabolism functions, and defense and immune functions. There is such a big difference in blood cells between insects, how different you think the substances contained in the blood should be, there are thousands of differences, but the oxygen transport of insects is borne by the tracheal system, so it has nothing to do with breathing, and its open circulatory system has low blood pressure, so insects will not directly endanger life due to blood loss. The blood of insects also often has a variety of colors, and the pigment substances contained in their blood make their blood show a specific color, such as carotene, riboflavin and flavon-nucleotides in the silkworm moth; flavonoids, fluorescein, and folic acid in silkworms; The green color of the larval blood of the butterfly is due to the co-presence of a yellow protein (whose cosylgroups are -carotene and lutein) and a blue protein (whose cogroup is biliverdin).

A similar component is found in the green blood of the dispersed locust, however, the green blood of a green bug is the result of the presence of a -carotene-protein complex and an approximate anthocyanin. These pigments in insect blood are generally thought to be obtained from food. In addition, the color of insect blood is also related to sex, such as the blood of larvae, pupae and adults of the butterfly, the female is green, and the male is yellow or colorless.

The body of an insect is divided into three parts: head, thorax, and abdomen. Adults usually have 2 pairs of wings and 6 legs, the wings and feet are located in the thorax, and the body is composed of a series of body segments, which are further assembled into 3 segments (head, thorax and abdomen). A pair of antennae are head-born, and the bones are wrapped around the body; The form of life is varied, and it is spread all over the world.

It's arthropods.

The one with the most variety. Insects do not have blood, but they do have blood-like lymph.

Because the insect's blood lacks red blood cells and does not transport oxygen (oxygen from the outside world passes through the trachea directly to the organs for oxygen), the insect's hemolymph is not red. On the contrary, depending on factors such as the food consumed, different species of insect hemolymph may appear different colors. <>

Insects are of great variety and morphology, belonging to the arthropods of invertebrates, and are the most abundant animal group on the planet, accounting for more than 50% of all biological species (including bacteria, fungi, and viruses), and their traces are found in almost every corner of the world. Until the beginning of the 21st century, there were more than 1 million species of insects known to humans, but there are still many species yet to be discovered. Insects are the most diverse and abundant in the animal kingdom and have a significant impact on agricultural production and human health [1].

The most common are locusts, butterflies, bees, dragonflies, flies, grasshoppers, cockroaches, etc. Not only are there many species of insects, but the number of individuals of the same species is also staggering. The distribution of insects is so wide that no other class of animals can compare with it, and it is almost all over the earth.

There are different types. Most insects can be used as specimens, and they are a good biological resource that humans can use. <>

There are parasites in the blood.

The specific common ones are as follows.

1 Plasmodium: Plasmodium is a malaria pathogen transmitted by mosquitoes, and the common malaria parasites are vivax, malaria malaria and falciparum malaria. Peripheral blood smear for Plasmodium parasites is a reliable method for diagnosing malaria, and a positive presence for malaria parasites can be used as a reliable basis for confirming the diagnosis.

A negative result does not negate the diagnosis, and it needs to be repeated several times or tested with genetic diagnostic methods.

2 Microfilariae: Microfilariae are the protozoa of filaria, and the common filarial infections in China include Bansonia and Malayan filaria, both of which are transmitted by mosquitoes. Peripheral blood smear is the main method of diagnosis, and a positive result is the basis for diagnosis, and negative results need to be repeated several times.

3 Relapsing thermospira: Relapsing respirochetes are pathogens of relapsing fever and are transmitted by human lice. A positive result is the basis for diagnosis, and a negative result requires multiple retests.

4 Toxoplasma: Toxoplasma gondii is the causative agent of toxoplasmosis, cats and felines are its main source of infection, and humans are generally infected. A positive result is the basis for diagnosis, and a negative result needs to be repeated several times, or tested with immunological methods and genetic diagnostic methods.

5 Lido bodies: Lido bodies are the causative agent of kala-azar and a type of flagellate, which can often be examined by liver and spleen aspirate fluid, as well as bone marrow and lymph node aspirate fluid. A positive result confirms the diagnosis, and a negative result requires repeat testing.

All parasites that live in the blood and blood cells can be detected in the blood, and these protozoa and filarial worms are parasitic in the blood and red blood cells of a person, and the diagnosis is confirmed by blood tests or bone marrow tests. Commonly used methods are blood smear (thin and thick) and bone marrow aspirate.

Insects are one of the oldest and most abundant groups of organisms on Earth, but did you know if insects have blood? The answer is that insects do have blood, but it is different from our human blood.

The blood of insects, also known as "hemolymph", is not the red blood we are familiar with, but a clear or light yellow liquid. In insects, the hemolymphtic main curvature is used to transport oxygen and nutrients, and also has the role of maintaining the stability of the insect's internal environment.

In addition, the blood of insects is composed of blood cells and blood lymph, of which blood cells are mainly used to defend against external germs and viruses, and play an important role in the body's immunity. Therefore, it can be said that inside insects, blood is a very important component.

Although the blood burial fluid of insects is different from the blood of our humans, it also has important biological significance. It is believed that with the continuous development of science and technology, more research on insect blood will help us better understand and recognize these wonderful creatures.

Insects have blood.

The blood of insects (more appropriately called hemolymph) is not involved in oxygen transport. The stomata on the insect allow oxygen from the air to diffuse directly into the tissues of the body.

Insect blood can come in many colors, depending on the type of blood cells in the insect and the color of the pigments it contains. Many insects have colorless or yellowish blood because they don't have red blood cells in their blood, but are made up of many other colored cells. Some insects have blue blood because they contain blue heme in their bodies.

The heart of the insect is a long tube leading to the end of the body at the bottom, there is an opening under the brain, this heart tube has many small openings like valves, blood flows into the heart from these small holes, the heart contracts, so that the blood flows to the head of the liquid file, and the blood flows through the body to the heart after the blood flows back, infiltrating the body's organs, muscles and nervous system, and carrying digested food to transport waste.

The large nerve center on the insect's head is the brain, and the brain receives signals from information release and commands the muscles to work, which are intuitive responses, and the insect's movements belong to automatic reflexes.

A parasite is an animal that can live in the intestines, liver, brain, etc., and will no longer be present in the bloodstream.

It is advisable not to panic, and the examination of the parasite can confirm the diagnosis by checking the eggs in the stool.

Eat more kidney-tonifying foods, such as black foods. Reasonable physical exercise.

Blood parasites are mainly infected by lice, which hide in blood cells and cause "blood parasitic infections".

Here are the three most common conditions:

1. Pyrosomiasis.

Burnworms mainly infect red blood cells in the blood, and the incubation period of the disease is about two weeks, although there are cases that can last for months or even years.

Symptoms: weakness, loss of appetite, pale mucous membranes, yellow bile, etc. In addition, there may be a large decrease in platelets in the blood, white blood cells may increase or decrease, or kidney failure may occur.

2. Ehrlichiosis.

Ehrlichia mainly infects white blood cells in the blood, which can lead to a decrease in the number of platelets, resulting in vasculitis, a decrease in the number of white blood cells, mild anemia, and severe anemia.

Symptoms: Ehrlichiosis is divided into two types: acute infection and slow infection.

3. Lyme disease.

Lyme disease usually causes arthritis, claudication, and loss of mental appetite.

Lyme disease is circulating around the world, with 90% of cases in the United States, but in recent years it has also appeared in Taiwan. The disease tends to occur in mammals, so dog owners should not ignore it.

Symptoms: Symptoms of Lyme disease in dogs include arthritis, sudden severe pain, claudication, fever, lethargy and loss of appetite, and severe infections may also affect the brain, heart and kidneys.

Break off the leg of a locust and it will come out with a gray-black liquid, which is its blood.

There is blood, and there are many insects, and if you look closely, you will find that there is very little blood because the insects are small.
