Most drugs, electrolytes, uric acid, urea, etc. are expelled from the body. When blood flows into the kidneys, it reaches the nephrons. There it undergoes processes like glomerular filtration, active tubular secretion, and passive tubular reabsorption. The waster formed is expelled in urine. Skin: Skin is one of the minor organs of excretion.
What are the different organs of excretory system?
If these useless waste products are allowed to accumulate in the body, they would become dangerous to the body's health. The kidneys, considered the main excretory organs in humans, eliminate water, urea, and other waste products from the body in the form of urine. Other systems and organs in the body also play a part in excretion.
What is the difference between solid waste and excretory waste?
The solid wastes are the indigested food that stored in the large intestine until it passes out of the body, And the excretory materials are expelled out of the body through the excretion process.
What is excreted from the digestive system?
The digestive system removes feces, the solid undigested wastes of digestion, by a process called defecation or elimination. The skin also acts as an organ of excretion by removing water and small amounts of urea and salts (as sweat).
What happens when the excretory system breaks down carbohydrates?
Excretory system. When cells break down carbohydrates (compounds consisting of carbon, hydrogen, and oxygen and used as a food), they produce water and carbon dioxide as waste products. If these useless waste products are allowed to accumulate in the body, they would become dangerous to the body's health.

For each molecule of glucose cells break down, they release six molecules of carbon dioxide (CO2) and six molecules of water. ... Liver. ... Kidneys. ... Skin.
What are the 4 functions of the excretory system?
The important functions performed by the excretory system include- elimination of wastes, eliminate waste byproducts excreted by the cells, prevent the accumulation of harmful chemicals in the body, and maintain a balanced chemical concentration in the body.
What part of the excretory system gets rid of worn out and dead cells?
The spleen is located in the upper left part of the belly under the ribcage. It helps protect the body by clearing worn-out red blood cells and other foreign bodies (such as germs) from the bloodstream.
What are the waste products in human body?
The kidneys Materials eliminated via the kidney include nitrogenous waste products (ammonia, uric acid, urea, creatine, creatinine, and amino acids), excess quantities of salts and water that may be taken into the body, and various other organic materials produced by life-sustaining chemical reactions.
What are the three main modes of excretion in animals?
They are: Ammonotelism (Type of excretion- ammonia) Ureotelism (Type of excretion – urea) Uricotelism (Type of excretion – uric acid)
Which one of the following is not removed as a waste product from the body of a plant?
So, the correct answer is 'Urea'
How are these wastes eliminated?
This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. ... Urine is a liquid waste formed by the kidneys as they filter the blood.
What are the 4 ways your body gets rid of waste?
ExcretionThe large intestine eliminates solid wastes that remain after the digestion of food.The liver breaks down excess amino acids and toxins in the blood.The skin eliminates excess water and salts in sweat.The lungs exhale water vapor and carbon dioxide.More items...•
What are the types of excretion?
Based on the excretory product, five modes of excretion are known in animals....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)
What are the excretory organs of the body?
The important human excretory organs are- kidneys, ureter, urethra, urinary bladder, skin, liver, intestine and lungs.
Which are the main excretory organs of the body?
The Human Excretory System | Back to Top. The urinary system is made-up of the kidneys, ureters, bladder, and urethra. The nephron, an evolutionary modification of the nephridium, is the kidney's functional unit. Waste is filtered from the blood and collected as urine in each kidney.
What is the system of excretion?
In complex organisms including humans, there is a specialized system for excretion called human excretory system . We all obtain our nutrients from different sources which are later digested and metabolized in our body.
How does the body remove waste from the body?
As we all know, the accumulation of the toxins may be harmful and the body removes all the metabolic wastes by the process called excretion. Different organisms follow different modes of excretion such as kidney, lungs, skin and eyes depending on their habitat and food habit.
What is the process where all the metabolic wastes are removed from the body?
Excretion is the process where all the metabolic wastes are removed from the body. Excretion in humans is carried through different body parts and internal organs in a series of processes.
How is urine produced?
Urine thus produced is passed to the urinary bladder via the ureters. The urinary bladder is under the control of the Central Nervous System. The brain signals the urinary bladder to contract and through the urinary opening called the urethra, we excrete the urine.
What excretory product do humans produce?
Humans produce urea as the major excretory product. Let us have a detailed look at the excretory system notes to explore the excretory system in human beings, different organs of the excretory system and the mechanism of excretion in humans. Also Read: Excretory Products and their Elimination.
What are the two parts of the nephron?
Each nephron has two parts- glomerulus and renal tubule. Glomerulus consists of a bunch of capillaries formed by afferent arterioles. Blood from glomerulus is carried away by efferent arterioles. The renal tubule starts with a cup-like structure called Bowman’s capsule and this encloses the glomerulus.
How many nephrons are in a kidney?
Each kidney contains a million nephrons. Capillaries of kidneys filter the blood and the essential substances like glucose, amino acids, salts, and the required amount of water get reabsorbed and the blood goes into circulation. Excess water and nitrogenous waste in humans are converted to urine.
What is the excretory system?
Photo by: krishnacreations. 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).
Which organs eliminate water and urea?
The kidneys, considered the main excretory organs in humans, eliminate water, urea, and other waste products from the body in the form of urine. Other systems and organs in the body also play a part in excretion. The respiratory system eliminates water vapor and carbon dioxide through exhalation (the process of breathing out).
What controls the flow of urine between the two?
A sphincter muscle around the urethra at the base of the bladder controls the flow of urine between the two. The volume of urine excreted is controlled by the antidiuretic hormone (ADH), which is released by the pituitary gland (a small gland lying at the base of the skull).
