Study Notes
Multiple Choice Questions
- Waste Management: An elastic, muscular organ that holds urine until it leaves the body is the bladder.
- Urea and Oxygen Concentration in Renal Vessels: When comparing urea and oxygen concentrations in the renal artery to those in the renal vein, urea is higher and oxygen is lower in the renal artery.
- Urine Composition: Urea is typically found at a higher concentration in urine compared to blood.
- Antidiuretic Hormone (ADH) Effect: ADH directly affects the kidneys.
- Aldosterone Secretion: Aldosterone is secreted by the adrenal gland.
- Sweat Composition: Sweat contains water, salt, and ammonia.
- Kidney Disorder: Nephritis is a kidney disorder where the functional units become inflamed.
- Homeostasis Organ: Kidneys filter blood and maintain body fluid balance.
- ADH Production: Antidiuretic hormone is produced by the hypothalamus.
- Urine Concentration and Blood Volume: Increased blood volume causes the kidneys to produce less concentrated urine.
- Urethra Blockage: A blockage in the urethra prevents urine from leaving the body.
- Kidney Reabsorption: Convoluted tubules are involved in water reabsorption in the kidney.
Additional Questions
- Ammonia to Urea Conversion: The kidney converts ammonia to urea.
- Nephron Location: The loop of Henle is located between the proximal and distal convoluted tubules.
- Nitrogenous Waste Product: Urea is the primary nitrogenous waste product formed from breaking down amino acids.
- Metabolic Waste: Carbon dioxide is a metabolic waste in humans, while oxygen is not a metabolic waste in humans.
- Bowman's Capsule Location: Bowman's capsules are found in the renal cortex.
- Kidney Homeostasis: To maintain homeostasis, kidneys actively excrete hydrogen ions when blood becomes acidic.
- ADH Effect on Water Reabsorption: When ADH levels increase in the blood, more water is reabsorbed, leading to decreased urine output.
- Kidney Filtering Units: Nephrons are the tiny filtering units in the kidneys.
- ADH and Urine Concentration: Increased ADH leads to increased urine concentration.
- Kidney Function and Excretion: Kidneys are responsible for removing toxins and waste from the body.
- What is the urinary bladder? The hollow, muscular organ that stores urine.
- What is urine composition? The main components in urine are water, urea, salts, and various other wastes.
- What is ADH? A hormone that regulates water reabsorption in the kidneys.
- What produces aldosterone? The adrenal glands.
- Sequence of Urine Movement through the Urinary System: Kidneys, ureters, bladder, and urethra.
- How Many Nephrons in Each Kidney? Each kidney contains about a million nephrons.
- What is a characteristic of a healthy kidney? A healthy kidney has no glucose in the urine.
- Glomerular Filtration Characteristics: The glomerulus is composed of small blood vessels and surrounded by Bowman's capsule. Filtration is promoted by the high blood pressure.
- What processes occur in the kidney? Filtration, reabsorption, and secretion to maintain a healthy concentration of blood substances.

- Kidney Parts (Fill in the Blanks): (Requires diagram, answer provided)
Long Answer Question
- Liver's Role in Excretion: The liver plays a crucial role in converting ammonia (a toxic waste product) into urea, which is then excreted by the kidneys.
