to blood after it is cleaned in
the kidneys?

1. identify what structures

carry urine from the kidneys?

Explanation:

Question 4

The kidneys filter blood to remove urea, excess water, and other waste products (forming urine). The filtered blood, now free of these waste materials (while still containing necessary components like blood cells, proteins, and appropriate levels of ions and water), is transported back into the main bloodstream via the renal vein. From there, it goes to the inferior vena cava and then to the heart to be pumped to the rest of the body to maintain normal physiological functions.

Question 5

In the urinary system, each kidney produces urine. The ureters are long, narrow tubes that connect the kidneys to the urinary bladder. Their smooth muscle layers contract in peristaltic waves to propel the urine from the renal pelvis (of the kidney) down to the bladder, where urine is stored until it is excreted through the urethra.

Answer:

After the blood is cleaned in the kidneys (where waste and excess substances are filtered out), the cleaned blood is returned to the circulatory system through the renal vein. It then continues to circulate throughout the body, delivering oxygen and nutrients to cells and removing other wastes via other excretory or metabolic pathways.
