Do tiny ants have hearts? Do ants have hearts and if so, what is it?

It is said to be 1/20 of an ant

Real I don't know, but cartoon on the flower ant has a heart

Ants belong to insects and have hearts, most of the hearts are located in the abdominal cavity, and its heart does not have a complex structure like the human heart, but on its back, there is a dilated tube attached to the large artery, which exercises the function of promoting lymphatic blood circulation through rhythmic beats.

Although its circulatory system is not like a human being, divided into veins and arteries, but a single open circulatory process, but the organs used to promote the circulation of green lymphatic blood throughout its body still exist, if there is blood on the ant's body, it is not easy to find, most of the ants' body color is red or black, but there are a few are green, ants living in the tropics, the body is actually metallic.

Precautions and key points for ants:

Ants, bees and wasps are close relatives and belong to the general family of wasps, Hymenoptera. The smallest ant is only a millimeter, which is about the size of the pinhole of an ordinary embroidery needle, or the size of a grain of millet. The largest ant we know is 52 millimeters, which is about the length of an adult's finger.

The ant's body is also protected by a hard exoskeleton with a wax-like substance attached to it. Ants do not have lungs, and gases such as oxygen and carbon dioxide are exchanged through small breathing holes in the exoskeleton, so the ant's head does not have an organ such as a nose.

Ants have hearts.

Ants belong to the class Insectidae, and the heart of an insect is a continuously enlarged part of the back of the dorsal blood vessels, and each bulging part is a ventricle. Most of the heart is located in the abdominal cavity, but some can reach the chest cavity anteriorly, such as grasshoppers and cockroaches. The number of ventricles that make up the heart varies greatly depending on the species of insect.

Many cockroaches have 11 ventricles, and silkworms have 8 ventricles; Less common than houseflies have three ventricles, while Trichophagous and lice have only one large ventricle, which is thought to be formed by the merger of several ventricles. The ends of the heart are usually closed, and each ventricle is flanked by pairs of fan-shaped pterygoid muscles. The main function of the heart is to create a rhythmic beat through alternating relaxation and contraction of the ventricles, to draw blood from the dorsal sinuses and press into the anterior large arteries.

Each ventricle generally has 1 pair of hilum, located at the end or middle of the ventricle, with an orifice that is vertical or oblique, and is the opening through which blood flows into the heart. But there are also a few species that have 2 or 3 pairs of heart gates. In some insects where ventricular enlargement is pronounced, the glum is still an external form that divides the heart into ventricles.

When the ventricles are dilated, the hilum opens to allow blood to flow into the heart, and when it contracts, the hilum closes the hilum and prevents blood from flowing back into the cavity.

Ants are insects, have hearts, and belong to arthropods, and the circulatory system of arthropods is very simple compared to others. Although its circulatory system is not divided into veins and arteries like a human being, but a single open circulatory process, the organ used to promote the circulation of green lymphatic blood throughout the body still exists, but its heart does not have a complex structure like the human heart, but on its back, there is a dilated tube attached to the large artery, which exercises the function of promoting lymphatic blood circulation through rhythmic beats. If there is blood on the ant, it is not easy to find.

Ants have hearts, which are so small that they are almost invisible to the naked eye. Ants have hearts, which are so small that they are almost invisible to the naked eye. Ants have hearts, which are so small that they are almost invisible to the naked eye.

Ants have hearts, ants belong to the class Insecta, and the heart of insects is a continuously enlarged part of the back of the dorsal blood vessels, and each bulging part is a ventricle.

No, it's so small,,, where does the heart come from, the heart is only found in mammals.

Although the sparrow is small, it has all kinds of organs. Ants also have hearts.

Ants don't have hearts.

Because it is not a mammal.

Ants are supposed to have no hearts.

I think there is, personal opinion.

There should be, otherwise how to breathe.

The heart of an insect is different from the heart of a mammal, but it also has the function of pumping blood to drive blood circulation, also known as the dorsal blood vessels.

The circulatory system of insects is open, and blood circulates in the body cavity, bathing all tissues and organs. The main function of the insect circulatory system is to transport nutrients and hormones to the corresponding tissues and organs or action sites, and to transport metabolites to other tissues or excretory organs, maintain normal metabolic activities and their required osmotic pressure, ion balance and pH, produce immune responses to foreign invasion, remove dissociated tissue debris, dead cells and large solid particles, and repair wounds.

First, the structure of the circulatory system.

The circulatory system of insects mainly consists of the dorsal blood vessels, the accessory device, the dorsal diaphragm, and the ventral diaphragm, which drive blood circulation.

1 The dorsal vessel is a long, slender tube with an open front end and a closed back end that runs through the dorsal blood sinus**, which is composed of muscle fibers and connective tissue, and is the main pulsatile organ of blood circulation. The dorsal blood vessels can be divided into two parts: the artery and the heart.

1) The artery (AORTA) is the thin, non-compartmentalized part of the anterior segment of the dorsal vessel, without a glum, and without the pterygoid muscle connecting to the diaphragm, the anterior end opens into the cephalic cavity, and the posterior end connects to the 1st ventricle, which is the conduit that directs blood to flow forward. The artery originates from the ectoderm and is located within the insect cephalothorax.

2) The heart is the part of the dorsal blood vessel that is continuously expanded, each bulging part is called the chamber, each ventricle is often on both sides of a pair of ostium, and the ventricle is connected to the diaphragm by a fan-like transverse dorsal muscle, that is, the pterygoid muscle. The hilum is the passage through which blood enters the heart, and its edge folds inward to form the ostial valve, which closes when the ventricles contract, forcing blood to flow forward in the dorsal blood vessels; When the ventricles are dilated, the hilar valve opens and blood flows from the body cavity into the ventricles. In this way, the ventricles contract sequentially from back to front, causing blood to flow from back to front in the dorsal blood vessels.

The heart originates from the mesoderm, and the heart of most insects is confined to the abdomen, while the heart of a few insects such as cockroaches and cockroaches extends into the chest. It is the main organ that keeps blood circulating in the body.

Spiders are not of the class of insects, they are of the class Arachnida, and they belong to the phylum Arthropods.

Yes. Insects have hearts, which makes it too difficult to say.
