Which substances are found in the glomerular filtrate in the kidneys of a mammal? Also, name the substance that fails to pass the glomerulus. [2]

24. How is the...



Answer :

Final answer:

Heating sodium hydrogen carbonate yields sodium carbonate, water, and carbon dioxide gas. Lymph is a fluid aiding the immune system and maintaining fluid balance. Glomerular filtrate contains various substances, with larger molecules not passing the glomerulus.


Explanation:

Sodium hydrogen carbonate is more commonly known as sodium bicarbonate or baking soda. When this solution is heated, it undergoes thermal decomposition to form sodium carbonate, water, and carbon dioxide gas.

Lymph is a colorless fluid that plays a crucial role in the immune system. It transports white blood cells, proteins, and excess tissue fluid back to the bloodstream, helps in fighting infections, and maintains fluid balance in the body.

In the glomerular filtrate in the kidneys of a mammal, substances like water, glucose, ions (sodium, potassium, chloride), urea, and amino acids are found. The substance that fails to pass the glomerulus is usually larger molecules like proteins and blood cells.
