Final answer:
The kidneys are the organs responsible for filtering waste products from the blood. They perform crucial roles such as removing metabolic wastes, regulating water and pH balance, and forming urine for excretion.
So, the correct answer is B.
Step-by-step explanation:
The part of the human body that is responsible for filtering waste products from the blood is the kidneys. These bean-shaped structures are located just below the liver and play several vital roles in maintaining the body's homeostasis. They remove metabolic waste products from the bloodstream, regulate the body's water balance, and maintain the pH of bodily fluids.
The process of filtration in the kidneys takes place within a million tiny units called nephrons, which concentrate waste products and form urine. This urine is then collected in the bladder and eventually excreted from the body.
The kidneys receive about one and a half quarts of blood per minute to filter, ensuring the cleanup of the bloodstream several times each day. Notably, while other organs like the liver, lungs, skin, and large intestine also play roles in excretion, it is the kidneys that are primarily responsible for filtering blood and eliminating urea and other soluble waste products in the urine.
So, the correct answer is B) Kidneys.
