Did you know that the average human being produces about 1.5 litres of urine every day? Or that we excrete about 10 grams of faeces? In this article, we will discuss what is the Human Excretory System, the Excretory System Organs, and how it works. We’ll also take a look at some of the amazing things that our excretory system does to keep us alive and healthy!
What is the Human Excretory System?
The Human Excretory System is a network of organs and tubes that work together to rid our bodies of waste. It includes the kidneys, liver, lungs, and skin. The Excretory System’s main job is to remove excess water, electrolytes, and wastes from our bodies. These wastes can come in the form of urine, faeces, and sweat.
Excretory System Organs
Here are the Excretory System Organs include:
A pair of kidneys: The kidneys are paired organs bean-shaped that lie just below the rib cage on either side of the spine. The kidneys filter wastes and excess fluid from the blood and produce urine.
– Ureters: The ureters are thin tubes that transfer urine from the kidneys and it takes into the bladder.
– Bladder: The bladder is a sac that stores urine until it is ready to be eliminated from the body.
– Urethra: The urethra is a tube that takes away urine from the bladder to the outside of the body.
What are the main functions of the Human Excretory System
The Human Excretory System is responsible for:
elimination of wastes: The Human body Excretory System helps to rid the body of wastes that it no longer needs. These wastes can come in the form of solid, liquid, or gas.
– maintaining water balance: The Human Excretory System also helps to maintain the proper balance of water in the body. This is important because it helps to ensure that the body’s cells are properly hydrated.
– regulating blood pH: The Human Excretory System also helps to regulate the pH of the blood. This is important because it helps to keep the blood at a level that is safe for the body to function.
– controlling blood pressure: The Human Excretory System also helps to control blood pressure. This is important because it helps to ensure that the blood is flowing at a safe and healthy rate.
What is the mechanism of the Human Excretory System?
The mechanism of the Human Excretory System is to remove wastes from the body. The system consists of a network of organs that cleanse the blood and get rid of toxins. These organs include the liver, kidneys, and lungs. The liver produces bile, which helps to break down fats. The kidneys filter out toxins and excess water from the blood. The lungs remove carbon dioxide from the blood. All of these organs work together to keep us healthy and alive.
Steps involved in human body excretion:
Glomerular Filtration:
The first step of excretion is called glomerular filtration. It happens in the kidneys and is considered the most important function of the human excretory system. The glomerulus is a tiny capillary network in the kidneys that filters blood plasma, removing waste products and excess fluid. The fluid that is filtered out is called glomerular filtrate.
Urine Formation:
The second step of excretion, urine formation, takes place in the kidneys. The kidneys remove waste products and excess fluid from the blood plasma and concentrate them in the urine. This process is called reabsorption.
Urination:
The third and final step of excretion is urination or the removal of urine from the body. This is done through the urethra, a tiny tube that leads from the bladder to the outside of the body. When you urinate, the muscles in your bladder contract and force urine out through the urethra. At the same time, the muscles in your pelvic floor relax to allow urine to pass.
Conclusion
In conclusion, the human excretory system is a complex network of organs and tubes that work together to rid our bodies of waste. The principal excretory organs are the kidney, ureter, urinary bladder, and urethra.The human excretory system is made up of organs that help the body eliminate nitrogenous wastes.The kidneys filter the blood and produce urine as the filtrate.Urine passes via the ureter and into the urinary bladder before being expelled from the body. Micturition is the term for this.This was an in-depth look of the human excretory system.
