- By regulating body temperature through sweat production.
- By transporting nutrients to cells throughout the body.
- By producing hormones that regulate blood sugar levels.
- By removing waste products and balancing fluids and electrolytes. (correct)

- Digestion of proteins into amino acids.
- Filtration of blood, reabsorption of essential substances, and excretion of waste. (correct)
- Secretion of hormones into the bloodstream.
What is the function of the glomerulus within the nephron?
What is the function of the glomerulus within the nephron?
- To reabsorb water and ions back into the bloodstream.
- To filter water, electrolytes, amino acids, glucose, and urea from the blood. (correct)
- To concentrate the urine by removing water.
- To secrete excess salts and toxins into the urine.

Study Notes
- The excretory system eliminates waste and maintains homoeostasis.
- The excretory system eliminates nonsolid waste from the body.
- Lungs, skin and kidneys help eliminate the non-solid waste in the body.
- Lungs exhale carbon dioxide and water vapor.
- Sweat glands in skin release excess water and salt.
- Kidneys filter and clean the blood to produce urine.
- Kidneys help maintain homeostasis by filtering blood.
- Kidneys are bean-shaped organs with two layers: medulla and cortex.
- Nephrons are filtering units found in the kidneys.
- Blood is filtered by the renal artery and renal vein.
- Kidneys remove waste from blood.
- Kidneys help maintain electrolyte, pH, and fluid balances.
- Kidneys release key hormones.
- Nephrons clean blood and produce urine.
- Nephrons clean and rebalance the blood to produce urine.
- Nephrons clean the blood in a three-step process: filtration, reabsorption and excretion.
- The first step in cleaning the blood is filtration of the blood.
- The second step in cleaning the blood is reabsorption of materials.
- The third step in cleaning the blood is excretion of materials.
- Injury and disease can damage kidney functions.
- A kidney transplant can replace a damaged kidney.
- For a kidney transplant to work, recipient and donor tissue must match.
- Drugs can prevent tissue rejection during kidney transplants.
- Dialysis is a process to filter and clean the blood.
