| What are the components of urine? | Mineral salts and urea dissolved in water |
| Hot temperatures and constant exercises has what effect on concentration and volume of urine? | More concentrated, less volume |
| What effect does high water intake has on urine concentration and volume? | Less concentration, more volume |
| What is the function of the renal artery in the excretory system? | brings blood and nitrogenous waste products to the kidneys to be cleansed |
| What occurs after blood is cleansed in the kidney to when it reaches the bladder? | Cleansed blood returns to the heart via renal vein.
Nitrogenous waste flow down the ureter as urine to the bladder to be stored |
| Function of the sphincter muscles | control release of urine from the bladder by contracting walls of the bladder |
| A weak bladder means... | that the sphincter muscles are weak and bladder does not hold as much urine |
| What is the cortex made up of? | Bowman's capsule, glomerulus, convoluted tubules of all nephrons |
| What is the medulla made up of? | loops of Henle, collecting ducts that open into the pelvis |
| Function of the pelvis | collects urine from the collecting ducts |
| What are the three main regions of the kidney? | Cortex, Medulla, Pelvis |
| What are nephrons, where are they found? | Nephrons are tiny structures that spans the cortex and medulla they are at the end of collecting ducts so urine flows through the ducts then into the pelvis. |
| What is the glomerulus, where is it found? | mass of capillaries, filters the blood during urine formation, enclosed by Bowman's capsule |
| Ultra Filtration occurs where | glomerulus |
