What are the small bean-shaped organs that filter out pathogens?
Lymph nodes are small bean-shaped tissues found along the lymphatic vessels. The lymph nodes act as filters. Various immune system cells trap germs in the lymph nodes and activate the creation of special antibodies in the blood.
What removes pathogens and dead cells from lymph?
The spleen also helps get rid of germs. It contains white blood cells called lymphocytes and macrophages. These cells work to attack and destroy germs and remove them from the blood that passes through the spleen.
What are the small bean-shaped masses of tissue that remove pathogens and dead cells?
Lymph nodes are small, bean-shaped masses of lymphatic tissue along lymph vessels. They store lymphocytes and filter waste, bacteria and damaged cells (including cancer cells) from lymph.

What are the two bean shaped organs located at the upper part of the urinary system?
kidneys
kidneys: two bean-shaped organs that filter waste from the blood and produce urine. ureters: two thin tubes that take pee from the kidney to the bladder. bladder: a sac that holds pee until it’s time to go to the bathroom. urethra: the tube that carries urine from the bladder out of the body when you pee.
What are the filters in the kidneys called?
Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.
Is a small bean shaped structure containing specialized lymphocytes?
lymph node, any of the small, bean-shaped masses of lymphoid tissue enclosed by a capsule of connective tissue that occur in association with the lymphatic vessels.
How are dead cells removed from the body?
But where do these dead cells go? Cells on the surface of our bodies or in the lining of our gut are sloughed off and discarded. Those inside our bodies are scavenged by phagocytes – white blood cells that ingest other cells. The energy from the dead cells is partly recycled to make other white cells.
What do lymph capillaries do?
Lymphatic capillaries are tiny vessels found in the tissues of most organs in your body. They transport and filter lymphatic fluid (lymph) from your body’s cells and tissues. Lymph capillaries help to keep consistent blood pressure and volume and prevent fluid buildup.
How do lymph nodes remove waste?
The lymph fluid carries the waste products and destroyed bacteria back into the bloodstream. The liver or kidneys then remove these from the blood. The body passes them out with other body waste, through bowel movements (poo) or urine (pee).
Why are kidneys bean shaped?
Explanation: The kidneys are two ‘bean-shaped’ organs in the lower back that serve to conserve water, maintain blood osmolarity, help in acid-base balance, and filter blood plasma. Urine is the fluid product produced by the kidneys which is excreted as waste from the body.
