Answer: Mechanical weathering breaks rocks into smaller pieces without changing their composition and chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
The filtrate is first refined and concentrated by the processes of <u>reabsorption and secretion</u>, which form the urine that leaves the body.
<h3>Process of filtration in kidney:</h3>
The glomerulus filters your blood, and the tubule restores necessary substances to your blood while removing waste. The glomerulus is nestled within a region of the kidney called the Bowman's Capsule. This is where filtration occurs. The high pressure causes some substances to pass through the capillary walls when blood is forced through the tiny capillaries. The walls serve as a filter or sieve. This is how the function of the nephron. A glomerulus filters your blood, while a tubule restores necessary substances to your circulation while removing extra waste. Each nephron has both of these functions.
