How do urea and urine differ, ureter and urethra differ, and carbon dioxide and and carbon monoxide differ?

Question

please make it as simple as you can...

Answer 1

Urea is an organic compound with the chemical formula (NH2)2CO and is a waste product from the metabolism of excess amino acids and is filtered out of the blood in the kidneys.

Urine is the liquid waste we produce which contains,amongst other things, urea in solution.

Ureter is the tube (1 from each kidney) which takes the urine from the kidney to the bladder (where the urine is tempoarily stored).

Urethra is the tube taking the urine from the bladder to the outside of the body.

Carbon dioxide is CO2 and produced during respiration.

Carbon monoxide is CO and can bind to haemoglobin irreversibly and is poisonous.

Answer 2

(Disclaimer - I am a mad professor, not a doctor...)

Urea is only one of the materials contained in urine.

The ureters are the 2 vessels that connect to the kidneys, the urethra is the single one that provides the exit path outside the body.

Carbon dioxide (CO2) is the gas emitted by animals as part of the respiration process. Carbon monoxide (CO) is the gas produced by inefficient combustion (fires, combustion engines, etc.).

Answer 3

URINE is the byproduct or fluid secreted by the kidneys, transported by the ureters to the urinary bladder where it is stored until it is voided through the urethra. It is a transparent solution that is clear to amber in color, and usually is light yellow. Urine is made up of a watery solution of metabolic wUrine contains large amounts of urea, an excellent source of nitrogen for plants. As such it is a useful accelerator for compost. Urea is 10,000 times less toxic than ammonia and is formed by the combination of the byproducts of deamination (2 NH3 molecules) and cellular respiration (1 CO2 molecule). Other components include various inorganic salts such as sodium chloride (the discharge of sodium through human urine is known as natriuresis).

astes (such as urea), dissolved salts and organic materials. UREA is an organic compound of carbon, nitrogen, oxygen and hydrogen, with the formula CON2H4 or (NH2)2CO.

Urea is essentially a waste product, although it is used by the body during times of volume reduction. In the later portions of the kidney collecting tubule, urea is reintroduced into the kidney medulla to raise osmolarity. Afterwards, water flowing through the collecting tubule follows back into the body by osmosis.

Urethra and Ureters

Ureters originate in the pelvis of the kidneys and terminate in the urinary bladder. They are about 25-33 cm long (10-13 inches) and capable of peristalsis as they move the urine along its length to the bladder. The urethra is the tube that carries the urine from the bladder to the outside. It is lined with mucous membranes and has a muscular layer that contracts helping to propel the urine.

Gender differences of the urethra.....

The female urethra is short (3.8 cm or 1.5 inches long).

The male urethra is longer (20 cm or 8 inches).

The female urethra is part of the urinary system.The male urethra is part of both the urinary system and the reproductive system. The female urethra goes directly from the urinary bladder to the outside at the front of the v****a between the labia minora.The male urethra passes through the prostate gland after leaving the bladder, and extends the length of the p***s.

Carbon dioxide and carbon monoxide are both compounds that contain carbon and oxygen. The difference between them is that carbon dioxide contains one molecule of carbon and two molecules of oxygen whereas carbon monoxide contains only one atom of oxygen to each atom of carbon.

This may see like a small difference, but it does affect the chemical properties of the two compounds making them different. In some ways, they are similar in that they are both colourless gases that have no smell. However, the important difference lies in the toxicity of the two gases. Carbon dioxide is a natural waste product of the process of respiration in living cells and so it tolerated to some extent in the body. It is a waste product and it is excreted when we breathe out. In contrast, carbon monoxide is a poison that forms a stable compound with haemoglobin in the blood and prevents oxygen getting to the body. It kills within minutes in high concentrations.
