Explanation:
In general, the human being eliminates three types of waste:
1. Waste in the form of gas: (carbon dioxide). The source of this waste is derived from the metabolism of the cells of the human body.
2. Liquid waste: urine and sweat. Urine is produced in the urinary system by glomerular filtration, reabsorption, and secretion. The kidneys make urine by filtering waste and excess water from the blood. Sweat is produced by sweat glands that are part of the epithelium. Urine and sweat contain salts, toxins, and water that must be removed from the blood through the filtering process.
3. Solid waste: feces or excrement. Feces come from the digestion process. Stool is made up of undigested food, bacteria, mucus, and cells from the lining of the intestines.
When there is no elimination of the different kinds of waste, the body can become intoxicated or poisoned producing infections such as septicemia or bacteremia and also generating acid base imbalances (if there is a retention of carbon dioxide in the human body).
We can conclude that the correct answer is:
Answer:
Three kinds of waste that humans must remove from their bodies:
1. Waste in the form of gas: (carbon dioxide).
2. Liquid waste: urine and sweat.
3. Solid waste: feces or excrement.
What are the sources of these wastes?
1. Waste in the form of gas: (carbon dioxide): The source of this waste is derived from the metabolism of the cells of the human body.
2. Liquid waste: urine and sweat. Urine is produced in the urinary system by glomerular filtration, reabsorption, and secretion. Sweat is produced by sweat glands that are part of the epithelium. Urine and sweat contain salts, toxins, and water that must be removed from the blood through the filtering process.
3. Solid waste: feces or excrement: Feces come from the digestion process.
Why is waste removal important to living organisms?
The removal of waste from the human body is very important since if carbon dioxide is not eliminated, it could cause an acid-base imbalance in the human body and generate systemic problems and death. If solid waste such as feces is not eliminated, for example in intestinal obstruction, bacteria can accumulate that can generate bacteremia or septicemia, and if urine and sweating are not eliminated, the body accumulates toxins that can poison it and damage internal organs.
