What is the function of the Malpighian tubules in insects?
Malpighian tubules have as their main function the regulation and control of haemolymph composition and volume. In carrying out this function it turns out that they respond in appropriate ways to changes in haemolymph composition, not only as directed by circulating hormones, but also autonomously.
What are Malpighian tubules write one function of it?
The function of Malpighian tubules of cockroach is that it absorbs the nitrogeneous waste products from haemolymph and convert them into the uric acid for excretion.
What is the function of the malpighian tubule system in insects quizlet?
What is the main purpose for the Malpighian tubule/ hindgut complex? Homeostasis: Removal of nitrogenous wastes (Malpighian tubules) and water ion balance (rectal glands).
What is the function of the Malpighian tubules in a grasshopper?
As excretory organs, the Malpighian tubules not only get rid of nitrogenous wastes, they help properly maintain the internal ionic balance of the insect.
What is the function of the excretory system in insects?
The removal of waste products of metabolism, especially nitrogenous compounds from the body of insects is known as excretion. The excretion process helps the insect to maintain salt water balance and thereby physiological homeostasis.
What is the main excretory product of insects?
* Most terrestrial insects produce uric acid as their main nitrogenous waste product. Uric acid is a relatively non- toxic and highly insoluble waste product.
What is the function of ileum in cockroach?
In cockroach lipid absorption occurs through crop. In termites and scarabaeids (White grubs) absorption occurs through ileum. In solid feeders, resorption of water from the faeces occurs in the rectum and the faeces is expelled as pellets.
What organs present in all the vertebrates produce urine and maintain the proper balance of fluids and salts in the blood?
The kidneys are a pair of bean-shaped organs present in all vertebrates. They remove waste products from the body, maintain balanced electrolyte levels, and regulate blood pressure.
Which is the critical feature that enables the mammalian kidney to concentrate urine?
As already indicated, the loop of Henle is critical to the ability of the kidney to concentrate urine. The high concentration of salt in the medullary fluid is believed to be achieved in the loop by a process known as countercurrent exchange multiplication.
What are the 4 functions of the excretory system?
The four functions of the excretory system are to get rid of wastes, eliminate useless byproducts excreted from cells, eradicate harmful chemical buildups and maintain a steady, balanced chemical concentration in the body.
What is the main excretory waste of insects?
* Most terrestrial insects produce uric acid as their main nitrogenous waste product. Uric acid is a relatively non- toxic and highly insoluble waste product. Therefore, it can crystallize out of solution, and may be either retained in the body, or eliminated as a solid waste material with little water loss.
