What is the excretory organ in flatworm?

Many invertebrates such as flatworms use a nephridium as their excretory organ. At the end of each blind tubule of the nephridium is a ciliated flame cell. As fluid passes down the tubule, solutes are reabsorbed and returned to the body fluids. Excretory system of a flatworm.

How does the excretory system works?

The Excretory system is responsible for the elimination of wastes produced by homeostasis. Both of the ureters lead the urine into the body's only urinary bladder, which expands and sends nerve impulses when full. From there, urine is expelled through the urethra and out of the body.

• Ureotelism: These animals produce urea as the main nitrogenous waste.
• Urecotellism: In these animals, uric acid is the main nitrogenous waste.

Why excretory system is important?

How does the kidney excrete waste?

The kidneys excrete a variety of waste products produced by metabolism into the urine. These include the nitrogenous wastes urea, from protein catabolism, and uric acid, from nucleic acid metabolism.

What are the waste products of the human body?

Some of the specific waste products that must be excreted from the body include carbon dioxide from cellular respiration, ammonia and urea from protein catabolism, and uric acid from nucleic acid catabolism.

What are the waste products of the body?

The excretory system is a system of organs that removes waste products from the body. When cells in the body break down proteins (large molecules that are essential to the structure and functioning of all living cells), they produce wastes such as urea (a chemical compound of carbon, hydrogen, nitrogen, and oxygen).

How does skin excrete waste?

Skin. Sweat glands in the skin secrete a fluid waste called sweat or perspiration; however, its primary functions are temperature control and pheromone release. Therefore, its role as a part of the excretory system is minimal. Sweating also maintains the level of salt in the body.

What is excretion in biology?

Excretion is a process by which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life.

What organ removes urea from the body?

Is sweat and urine the same thing?

Incidentally, these same components are found in urine, which is produced by the kidneys. Yes, urine and sweat essentially contain the same chemicals, but in different concentrations. Therefore, both of these organs are responsible for waste homeostasis.

What is human excretory system?

The systems that excrete wastes from the body. For example, the system of organs that regulates the amount of water in the body and filters and eliminates from the blood the wastes produced by metabolism. The principal organs of the excretory system are the kidneys, ureters, urethra, and urinary bladder.

What do Crayfish eat?

? Crayfish, being omnivorous, can eat anything that they find. Their diet consists of vegetables like frozen peas, carrots, and even plants like Java moss. They also eat shrimp, meat, fish, insects that accidentally fall into the tank, sinking pellets, table scrap, etc.

How do crayfish reproduce?

Crayfish mate in the early spring and females carry the fertilized, developing eggs inside their bodies for 4 to 6 weeks. These developing eggs are then transferred to the outside of the female's body and glued via an adhesive called “glair” to the female's tail. The eggs then hatch by the end of spring.
