excretion

• Other organs involved in excretion include the lungs, which eliminate carbon dioxide, and the skin, which eliminates sweat and other waste products.
• The bladder stores urine before it leaves the body.
• Ureters carry urine from the kidneys to the bladder.
• The kidneys filter waste and excess fluid from the blood to produce urine.
• In humans, the main organs involved in excretion are the kidneys, which filter waste products from the blood and produce urine.
• Filtrate passes through tubules where reabsorption occurs, with only small amounts being eliminated from the body as urine.
• Urine is formed by filtration of blood through glomeruli in the nephrons of the kidney.
• The kidneys are responsible for filtering blood to remove excess water, electrolytes, and nitrogenous wastes such as urea.
• The kidneys filter waste products from the blood and produce urine, which is then excreted from the body.
• The liver produces bile, which helps break down fats during digestion.
• Excess water is removed by osmosis across semipermeable membranes.
• Bile is stored in the gallbladder until needed by the small intestine.
• Glomerulus - network of capillaries that filters blood
• Nephron - functional unit of the kidney
• Bowman's capsule - collects filtered substances
• Renal tubule - collects filtered substances and returns them to circulation if necessary
• Kidney - organ involved in filtration, reabsorption, secretion, and regulation of fluid balance
• Proximal convoluted tubule - reabsorbs most substances back into bloodstream
• Loop of Henle - allows concentration of urine to occur
• Proximal convoluted tubule - reabsorbs most useful substances from filtrate
• Ureter - tube that carries urine from the kidneys to the bladder
• Ureter - tube that carries urine from the kidneys to the bladder
• Bladder - temporary storage site for urine
• Urinary system - organs responsible for filtering waste products from the body
• Kidney - organ responsible for removing wastes, regulating blood pressure, producing hormones, and maintaining fluid balance.
• Nephron - functional unit of the kidney involved in filtering blood and forming urine.
