How do flatworms remove waste?
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. Water is reabsorbed and waste is expelled from the insect.
What is the excretory system of flatworm?
Flatworms have an excretory system with a network of tubules throughout the body that open to the environment and nearby flame cells, whose cilia beat to direct waste fluids concentrated in the tubules out of the body. The system is responsible for regulation of dissolved salts and excretion of nitrogenous wastes.
How the osmotic regulating excretory system of Planarians operate?
They also maintain the organism’s osmotic balance. In the excretory system of the (a) planaria, cilia of flame cells propel waste through a tubule formed by a tube cell. As the filtrate passes down the tubules, nutrients and other solutes are reabsorbed by capillaries.
How does excretion occur?
Excretion is a process in 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 is called excretion?
Excretion is a general term referring to the separation and throwing off of waste materials or toxic substances from the cells and tissues of a plant or animal. The separation, elaboration, and elimination of certain products arising from cellular functions in multicellular organisms is called secretion.
What organ removes water from the body?

What are the 4 ways your body gets rid of waste?

Which organ helps in solid waste?
large intestine
What are the four types of excretion?
They are:
- Ammonotelism (Type of excretion- ammonia)
- Ureotelism (Type of excretion – urea)
- Uricotelism (Type of excretion – uric acid)
- Aminotelism (Type of excretion – amino acids)
- Guanotelism (Type of excretion – guanine)
How do humans excrete waste?
Humans have two kidneys and each kidney is supplied with blood from the renal artery. The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. The urinary bladder collects and stores the urine until urination.
Where in your body does all the waste go right before it leaves the body?
The rectum is the final 6 to 8 inches (15 to 20 centimeters) of the large intestine. It stores stool (poop) until it leaves the body.
