So our question is what are the main functions of the excretory system elaborate, explain the process of excretion of waste materials in the body step by step and explain how the kidney are responsible for the regulation of blood pressure in the human body.
00:21
So let's discuss all the questions one by one.
00:24
You know the excretory system is the structure formed by different.
00:30
Organs and whose you know primary function is to eliminate the excess of unnecessary materials from body fluids right the objective of the system is to keep the homeostasis or we can say the chemical balance and avoid pain in our body so you know the steps involved in and we can say, you know, the process of excretion of the wasteful materials in the human body includes.
01:10
So the first is the urination, right? the urination system excretes urea from the body, right? so urea is produced when your body breaks down food rich in protein.
01:28
So it is then carried through the bloodstream to the kidneys, right? the urea is, you know, filtered from the blood of minuscule filtering units within the kidney called nephrons, right? uria, along with water and other waste substances, you know, form urine as it passes through the nephrons and down the renal tube.
01:57
So in the respiration, in the respiration, okay, before that, you know, i must tell you from the kidney, you know, the urine, the urine passes down two small tubes called ureters through to blader, right? so, ureters are constantly tightening and relaxing in order to force the urine away from the kidney.
02:26
So the small amount of urine are released into the bladder from the ureters, you know, circular muscles called as pinchers, you know, help to keep the urine from leaking.
02:40
Nerves and the bladder tell you when it's time to empty, right? so in the case of the respiration, since the broader definition of excretory system is not confined to urinary system, how does the excretory? system work except letting the urine out right so one of the answer is breathing out the gaseous waste via respiration right so the protein fat and carbohydrates that we consume are eventually converted to glucose so this glucose is then greeted by oxygen right in a chemical reaction cellular oxidation, right, which produce the energy to drive all other bodily functions and chemical reactions of cell.
03:41
The products of the reaction are carbon dioxide and water.
03:46
The carbon dioxide is dissolved in the blood and carried to the lungs via the respiratory system where it is breathed out, right? so in the case, of sweating...
