Human Excretion and Kidney Function

excretes carbon dioxide = 1 excretes urea = 2 produces urea = 3

production of urea = liver excretion of urea = kidneys storage of urine = bladder

carbon dioxide = lungs excess water = kidneys salts = liver urea = skin

The process of removing the nitrogen-containing part of amino acids to form urea.

A waste product containing nitrogen, produced during the breakdown of amino acids in the liver and excreted by the kidneys.

The removal of metabolic waste products from the body.

The outer layer of the kidney, containing the glomeruli and convoluted tubules.

The inner layer of the kidney, containing the loop of Henle and collecting ducts.

The tube that carries urine from the kidney to the bladder.

The process of filtering blood in the glomerulus to form filtrate.

The small blood vessel network within the glomerulus where filtration occurs.

The fluid that is formed during filtration in the glomerulus, containing water, glucose, urea, and salts.

The process of reabsorbing useful substances like glucose, amino acids, and water back into the blood from the filtrate in the kidney tubule.

The first coiled section of the kidney tubule after the glomerulus, where most reabsorption occurs.

The part of the kidney tubule where water reabsorption is regulated.

The second coiled section of the kidney tubule, where fine-tuning of ion concentration and pH occurs.

The main organ responsible for excretion, filtering blood to produce urine.

The organ that stores urine before it is released from the body.

The process of controlling the composition of the blood by removing waste products and excess water, maintaining homeostasis.

The process of removing excess water, salts, and urea from the body through urine.

The process of removing excess water and salts from the body through sweat.

The process of removing excess carbon dioxide from the body through the lungs.

The process of removing waste products through the digestive system.

The substance that is removed from blood during filtration in the glomerulus.

The process of artificially filtering and cleaning the blood when the kidneys fail.

A condition where the kidneys fail to filter blood properly, leading to a buildup of waste products in the body.

The condition of having too much water in the body, which can lead to swelling and problems with electrolyte balance.

The condition of having too little water in the body, which can lead to dehydration and electrolyte imbalance.

Any substance that can be dissolved in a solvent, like water.
