Plants utilize various strategies to excrete waste, including the release of oxygen during photosynthesis, transpiration to eliminate excess water, storage of waste products in cellular vacuoles, shedding of leaves and other parts containing waste, and secretion of waste substances into ...

The urge to urinate is controlled by nervous signals that regulate the contraction and relaxation of the muscles in the urinary bladder. These signals are under conscious control, allowing individuals to suppress or initiate urination voluntarily.

The urinary bladder acts as a temporary storage reservoir for urine. It expands as urine accumulates and contracts when it’s time to urinate, exerting pressure that triggers the urge to pass urine through the urethra.

The ureter is a long tube that connects each kidney to the urinary bladder. Its primary function is to transport urine from the kidneys to the bladder for storage.

During re-absorption, essential substances like glucose, amino acids, salts, and water are selectively re-absorbed from the initial filtrate back into the bloodstream. This process helps maintain the body’s balance of water and electrolytes while eliminating waste products.
