The Process of Filtering Waste Containing Body Fluids in the Kidneys

The correct answer is option B - kidneys. The process of filtering waste containing body fluids is carried out by blood capillaries in the kidneys. Let's understand this process in detail.

Kidneys and their Function
The kidneys are a pair of bean-shaped organs located on either side of the spine, just above the waist. They are a vital part of the urinary system and play a crucial role in maintaining the body's overall health. The primary function of the kidneys is to filter waste products and excess fluids from the bloodstream, producing urine as a result.

Blood Capillaries in the Kidneys
The kidneys contain millions of tiny filtering units called nephrons. Each nephron consists of a cluster of blood capillaries known as the glomerulus, surrounded by a hollow tubule. These blood capillaries play a crucial role in the filtration process.

Filtration Process in the Kidneys
1. Blood enters the kidneys through the renal artery, which branches into smaller arteries and eventually into microscopic blood vessels called capillaries.
2. As blood flows through the glomerulus, the high pressure in these capillaries forces small molecules such as water, waste products, and dissolved substances (e.g., urea, creatinine) out of the bloodstream and into the tubule of the nephron.
3. The filtered fluid, known as the filtrate, then moves through the tubule, where essential substances like glucose, water, and salts are reabsorbed back into the bloodstream.
4. The remaining waste products and excess fluids continue through the tubule and eventually form urine, which is then collected in the renal pelvis and transported to the bladder for storage and eventual elimination from the body.

Importance of Filtering Waste
Filtering waste containing body fluids is a crucial process as it helps in maintaining the body's water and electrolyte balance. It also helps in removing harmful substances and toxins from the bloodstream, ensuring that the body functions properly.

Conclusion
In conclusion, the process of filtering waste containing body fluids is carried out by blood capillaries in the kidneys. The kidneys play a vital role in maintaining the overall health of the body by filtering waste products and excess fluids from the bloodstream, producing urine, and eliminating it from the body.
