The tubular structures that carry waste from the kidney are the renal tubules, specifically the collecting ducts. After filtration in the nephron, waste products and excess substances are reabsorbed and secreted through the renal tubules, eventually leading to the collecting ducts. From there, urine is transported to the renal pelvis and then to the ureter for excretion.
Blood carries waste products to the kidney when it is filtered out forming urine.
The kidney is the organ that filters waste from the blood. Millions of tiny structures called nephrons in the kidneys help in the filtration process by removing waste and excess substances from the blood to form urine.
The phylum Annelida includes worms that excrete waste through structures called nephridia. Nephridia are tubular structures that filter waste from the coelomic fluid and release it outside the body through pores called nephridiopores.
The waste leave the kidney through the nephrons, which separate waste materials, while waste in blood from capillaries, and the wastes all together through a collecting duct. Collecting ducts join together join into the ureter and the ureter leads the waste out of the kidneys, which veins carry the cleansed blood out of the kidney.
Tubular secretion is the process by which substances from the blood are actively transported into the renal tubules of the kidney to be excreted in urine. This process helps in regulating the concentration of ions, pH balance, and waste removal from the body. It also plays a role in the elimination of certain drugs and metabolic by-products.
The human organ that is similar in function to the nephridium in worms is the kidney. Both structures function to filter waste products from the bloodstream and regulate the balance of fluids and electrolytes in the body.
