Question

Draw an excretory system in human beings and level the following organs of the excretory system which performs the following functions.
(a) form urine
(b) is a long tube which collects urine from the kidney
(c) store urine until it is passed out

Answer 1

Hint: A system which eliminates the unwanted substances from our body. Cells produce water and carbon dioxide as by-products of the metabolic breakdown of sugars, fats, and proteins. The continuous production of metabolic wastes establishes a steep concentration gradient across the plasma membrane, causing wastes to diffuse out of cells and into the extracellular fluid.

Complete answer:
First of all the system present in an organism's body that is responsible for the function of excretion, the bodily process of discharging wastes is known as the excretory system. The Excretory system regulates the chemical composition of body fluids through the elimination of metabolic wastes and retaining the proper amounts of water, salts, and nutrients.

We all know that the excretory system expels the waste that generates in our body. In humans, the excretory system takes care of waste generation and elimination with the help of the following structures: 2 Kidneys, 2 Ureters, 1 Urinary bladder, 1 Urethra.
Kidneys:
The kidneys are the main organ of the human excretory system and every individual has a pair of kidneys. They are located posteriorly one on each side of the spine at the level of the liver. Our kidneys filter wastes and excess fluids from your blood, which are then excreted in your urine.
Ureters:
There is a thin muscular tube that comes out of each kidney as an extension of the renal pelvis which is known as the ureter. It carries urine from the kidneys to the bladder.
Urinary Bladder:
A sac-like structure with smooth muscle layer lining present in the excretory system which is called the urinary bladder. It stores the urine until expelling urine from the body. The bladder receives urine from the ureters, one from each kidney.
So, the correct answer is that urine is produced by the kidneys which are carried by the ureters and stored in the urinary bladder until it is passed out.

Additional information:
1) A human bladder can stretch to hold about 400 ml of urine.
2) All the blood in our body is filtered 400 times through the kidney every day.
3) It eliminates waste products in the body such as urea, uric acid ammonia, and other waste products.
4) It is involved in the process of osmoregulation, a process that maintains the proper amount of electrolytes in the body regardless of external factors like temperature, diet, and weather conditions.

Note: In addition to the kidneys, the excretory system also includes the liver, lungs, and skin in vertebrates. Not all animals use the same routes to excrete their wastes the same way as humans do. Excretion applies to metabolic waste products that cross a plasma membrane as well as elimination as feces.
