Do locusts have a lymph system?
827641
Locusts do not have separate, closed circulatory systems comparable to mammals. They have an open system, basically the entire internal portion of their exoskeleton is filled with a fluid (hemolymph) that transports immune cells, nutrients, amino acids, waste products, hormones, etc. There is an organ loosely corresponding to the heart that keeps the fluid moving but there are no veins or arteries or lymph glands or lymph vessels.

Lymph nodes are part of a  lymph vessel system that branches throughout the human body. There are about 100 (not sure if anyone has counted them all) that end up at a point called a 'lymph node'. The lymph vessel system is part of the immune system. It's job is to filter the body of foreign debris and than at some point returns back to the blood stream. Microscopic cancer cells that seed from a 'primary tumor' have the ability to enter the lymphatic system and travel throughout the body and lodge almost anywhere.\nSome notable locations for the lymph nodes are  neck, groin, armpit,  central chest, and abdominal cavity. \n\nLymphatic System\nhttp://en.wikipedia.org/wiki/Lymphatic_system\n\nLymph Node\nhttp://en.wikipedia.org/wiki/Lymph_node

No. All insects have an exoskeleton, a hard covering or special skin (cuticle), which provides support and protects them from water loss. Because of their high surface to volume ratio, insects have the potential to lose water rapidly. The hard cuticle is coated with waxes (long chain hydrocarbons similar to those found in beeswax) which minimizes water loss.

Different pathological functions in the mosquito.  Insects get sick from different diseases than humans.

Yes they do. In fact, all insects have hearts but they sure don't look like our big mammalian hearts. A mosquito's heart is a long, skinny, fragile tube that runs along its back, starting near the aNnus', to the chest cavity (the thorax). The tube actually extends to its head but only the abdomen part has muscles to contract and is called the heart.\nA bug's heart contracts (as ours does) to squeeze green (or colorless) blood forward through the heart from chamber to chamber toward the thorax. There the heart simplifies into a plain tube (the aorta) that carries the blood (called hemolymph) to the head. The blood sloshes around in the head, bathing the brain and organs. When each chamber of the heart relaxes, valves open and blood rushes into the heart from the body cavity — but not via blood vessels. \n\nThe blood circulates freely in the body cavity making direct contact with internal tissues and organs. It delivers nutrients, salts, and hormones and whisks away wastes with each heartbeat.\n\nAnuradha

On average, an ant has approximately 100,000 neurons in it's central ganglia.  It's interesting that you ask this, because ant colonies are commonly used to demonstrate the possible behavior of a 'dissociated brain" colony, in which the entire colony is a single organism.  A very large colony of ants could have as many as 1 billion neurons total...still many orders of magnitude less than a human, but pretty bright for an insect!

Many larval insects are technically the dirtiest looking. Many critters like leaf beetle larvae and aphid lions (lacewing larvae) will actually cover themselves in excrement or the dead bodies of their prey in order to provide themselves with camoflage.\nFlies can be dirty, well more specifically the flesh flies and $hit flies. It all depends on what the fly is feeding on, if it is feeding on nectar, then no, but if they spend their time on rotting carcases and on feces, then yeah they could possibly be a huge vector for disease.

Lymph nodes, also incorrectly called "Lymph glands" (they do not secrete anything and are therefore not glands), are components of the lymphatic system. Lymph nodes act as filters, with an internal honeycomb of connective tissue filled with lymphocytes that collect and destroy bacteria and viruses. When the body is fighting an infection, these lymphocytes multiply rapidly and produce a characteristic swelling of the lymph nodes. Humans have approximately 500-600 lymph nodes. Clusters of lymph nodes are found in the underarms, groin, neck, chest, and abdomen

The lymphatic system and the cardiovascular system are closely related structures that are joined by a capillary system. The is important to the body's defense mechanisms. It filters out organisms that cause disease, produces certain white blood cells and generates antibodies. It is also important for the distribution of fluids and nutrients in the body, because it drains excess fluids and protein so that tissues do not swell up. "Lymph" is a milky body fluid that contains a type of white blood cells, called "lymphocytes," along with proteins and fats. Lymph seeps outside the blood vessels in spaces of body tissues and is stored in the "lymphatic" system to flow back into the bloodstream. Through the flow of blood in and out of arteries, and into the veins, and through the lymph nodes and into the lymph, the body is able to eliminate the products of cellular breakdown and bacterial invasion. Two very large areas are of significance in this system - the right lymphatic duct which drains lymph fluid from the upper right quarter of the body above the diaphragm and down the midline, and the thoracic duct, a structure roughly sixteen inches long located in the mediastinum of the pleural cavity which drains the rest of the body. It is through the actions of this system including the spleen, the thymus, lymph nodes and lymph ducts that our body is able to fight infection and to ward off invasion from foreign invaders. Lymph plays an important role in the immune system and in absorbing fats from the intestines. The lymphatic vessels are present wherever there are blood vessels and transport excess fluid to the end vessels without the assistance of any "pumping" action. There are more than 100 tiny, oval structures (called lymph nodes). These are mainly in the neck, groin and armpits, but are scattered all along the lymph vessels. They act as barriers to infection by filtering out and destroying toxins and germs. The largest body of lymphoid tissue in the human body is the spleen. \n\nThe immune system is composed of many interdependent cell types that collectively protect the body from bacterial, parasitic, fungal, viral infections and from the growth of tumor cells. Many of these cell types have specialized functions. The cells of the immune system can engulf bacteria, kill parasites or tumor cells, or kill viral-infected cells. Often, these cells depend on the T helper subset for activation signals in the form of secretions formally known as cytokines, lymphokines, or more specifically interleukins. The purpose of this article is to review the organs, cell types and interactions between cells of the immune system as a commentary on their importance and interdependence on the T helper subset. Such an understanding may help comprehend the root of immune deficiencies, and perceive potential avenues that the immune system can be modulated in the case of specific diseases.\n\n\n\n\nThe Organs of the Immune System\nBone Marrow -- All the cells of the immune system are initially derived from the bone marrow. They form through a process called hematopoiesis. During hematopoiesis, bone marrow-derived stem cells differentiate into either mature cells of the immune system or into precursors of cells that migrate out of the bone marrow to continue their maturation elsewhere. The bone marrow produces B cells, natural killer cells, granulocytes and immature thymocytes, in addition to red blood cells and platelets. \n\nThymus -- The function of the thymus is to produce mature T cells. Immature thymocytes, also known as prothymocytes, leave the bone marrow and migrate into the thymus. Through a remarkable maturation process sometimes referred to as thymic education, T cells that are beneficial to the immune system are spared, while those T cells that might evoke a detrimental autoimmune response are eliminated. The mature T cells are then released into the bloodstream. \n\nSpleen -- The spleen is an immun

They have an exoskelton -- a hard exterior chitin based jointed "shell", that breaks down somewhat like bones -- very slowly and becoming a dusty particles.  After several months or years, they will just crumble at the touch.  So they do decompose.\n\nThe internal structure decompose very rapidly, but thanks to the exoskelton, you don't see it.

Only a few insects have ‘ears’. Among the insects that have hearing organs are the grasshoppers, crickets, katydids, cicadas and some moths. The short-horned grasshoppers, often called locusts have their hearing organs located on the side of their abdomens.\n\nThe long-horned grasshoppers, katydids and crickets have their ears on their front legs.\n\nMost insects have some hair on their bodies and when these vibrate, they know that something is approaching.

ticks, but they are bugs. I do not know of any animals. But yes what was said above, and bed bugs. Lice, scabies, parasites, etc...

No ,they are in the kingdom animalia.So like other worms they possess no cell walls. they only have cuticles to protect them from being digested in the gut.

It's not saying that there are only insects with four legs.\n\nIt's saying- in verse 21- that there are some insects you can eat- those with four feet which are used to jump to the Earth with \n\nthen in verse 22: for example, the locust, the bald locust, the beetle, the grasshoper, etc.\n\nSometimes it helps to read other versions other than King James Version (which can be harder to read)\n\nFrom the New international version:\n\nThere are, however, some winged creatures that walk on all fours that you may eat: those that have jointed legs for hopping on the ground. 22 Of these you may eat any kind of locust, katydid, cricket or grasshopper. 23 But all other winged creatures that have four legs you are to detest.\n\n\n\nverse 23: but any other insects (other than those listed above) you shall not eat.
