Question: Given the question: What is the final step of the following process: -  The kidneys receive blood from the renal artery - They process it with millions of tiny nephrons - Remove all the waste - The kidneys return the blood back to the body through the renal artery
The answer is:
Answer: The final step of the process involving the kidneys receiving blood from the renal artery, processing it with millions of tiny nephrons, and removing all the waste, is the return of the filtered blood back to the body through the renal vein.

To provide a comprehensive understanding of the process, let's break it down step-by-step:

1. Blood enters the kidneys through the renal artery: The renal artery branches off from the aorta and carries oxygen-rich blood into each kidney. This blood supply contains various substances, including waste products that need to be filtered out by the kidneys.

2. Nephrons process the blood: Kidneys contain around 1 million tiny filtering units called nephrons. Each nephron has a glomerulus and a tubule – two essential structures to the blood filtering process. The glomerulus is a small cluster of blood vessels or capillaries where blood filtering begins. The tubule is a long tube-like structure where the filtered fluid turns into urine.

3. Filtration and reabsorption: As blood passes through nephrons, the waste products, excess fluids, and electrolytes are filtered out. This process occurs in three steps: filtration, reabsorption, and secretion. In the glomerulus, water, and small solutes are filtered out of the blood and enter the nephron's tubule. As the filtrate travels through the tubule, essential substances such as glucose, amino acids, and some electrolytes are reabsorbed into the bloodstream. Waste products and excess electrolytes remain in the tubule and are expelled from the kidney as urine.

4. Urine collects in the renal pelvis: The filtered waste products, now in the form of urine, travel from the tubules to the renal pelvis. The renal pelvis is a funnel-shaped structure that collects the urine before it moves on to the ureters.

5. Urine travels through the ureters to the bladder: The ureters are tubes that connect each kidney to the urinary bladder. As urine leaves the renal pelvis, it travels through the ureters and is stored in the bladder. The bladder then expands as it fills with urine until it's full, triggering the need to urinate.

6. The final step - return of the filtered blood to the body: After the filtration, reabsorption, and secretion processes, the remaining blood, now cleansed of waste products and excess substances, leaves the kidneys through the renal veins. The renal veins transport the filtered blood back into the body's circulation, where it rejoins the bloodstream and continues to supply the body's tissues and organs with oxygen and essential nutrients.

In summary, the final step in the process is the return of the filtered blood back to the body through the renal veins. This process ensures that the body's blood is continuously cleansed and balanced, maintaining overall health and homeostasis.
