Final answer:
The spleen filters foreign particles from the blood, with lymphocytes destroying any pathogens that are captured. So, correct option is (C).
Step-by-step explanation:
The correct answer is c) Spleen. The spleen filters and stores blood, removing damaged red blood cells and serving as a reservoir for immune factors. It also helps maintain an environment free of microorganisms in the blood. While the liver and kidneys also filter the blood, they do so for different purposes. The liver removes damaged or defective red blood cells, while the kidneys filter the blood to remove waste products and eliminate them in the urine.
The spleen is located in the abdomen below the lungs and is responsible for filtering out toxins and pathogens from the blood. Lymphocytes within the spleen then destroy any pathogens that are filtered out. While the kidneys and liver also play significant roles in filtering the blood, it is the spleen that specializes in filtering foreign particles, particularly microbes, from the blood.
The kidneys filter the blood to remove waste and excess substances, creating urine. They contain millions of nephrons that each day filter a large volume of filtrate, which is then processed into urine. The function of the liver is quite varied; it filters blood coming from the digestive tract, detoxifies chemicals, metabolizes drugs, and also removes damaged or defective red blood cells.
