HAP renal system medium flashcards

All 15 cards

1. Card 1

   Which of the following organs is NOT considered part of the renal system? A. Kidneys B. Ureter C. Urinary bladder D. Adrenal glands

   D. Adrenal glands. The renal system is comprised of the kidneys, ureters, urinary bladder, and urethra. Adrenal glands are endocrine glands located on top of the kidneys but are not part of the renal system's primary organs.

2. Card 2

   The kidneys are described as the 'ultimate regulator of homeostasis' primarily because they: A. Produce hormones for growth B. Maintain fluid volume and composition C. Digest nutrients D. Filter air for respiration

   B. Maintain fluid volume and composition. The kidneys play a vital role in regulating the internal environment by maintaining the body's fluid volume and composition, which is crucial for homeostasis.

3. Card 3

   Where are the kidneys situated in the body? A. In the abdominal cavity, anterior to the peritoneum B. In the retroperitoneum C. In the thoracic cavity D. Inferior to the urinary bladder

   B. In the retroperitoneum. The kidneys are two paired organs situated in the retroperitoneum, meaning they are located behind the peritoneum.

4. Card 4

   Which of the following is a gross anatomical component of the kidney? A. Nephron B. Glomerulus C. Cortex D. Bowman's capsule

   C. Cortex. The gross anatomy of the kidney is composed of the cortex and medulla. Nephrons, glomeruli, and Bowman's capsules are microscopic structures within the kidney.

5. Card 5

   Which of the following is NOT one of the three main processes undertaken by the kidneys? A. Filtration B. Secretion C. Digestion D. Reabsorption

   C. Digestion. The kidneys undertake three primary processes: filtration, secretion, and reabsorption, all essential for their function in maintaining fluid balance and waste removal.

6. Card 6

   What is the outermost layer of the kidney? A. Renal capsule B. Adipose tissue C. Renal fascia D. Renal medulla

   C. Renal fascia. The layers of the kidney, from superficial to deep, are renal fascia, adipose tissue, and renal capsule.

7. Card 7

   The functional unit of the kidneys, responsible for filtering blood and performing selective reabsorption, is called the: A. Neuron B. Alveolus C. Nephron D. Hepatocyte

   C. Nephron. The nephron is the functional unit of the kidneys, with over a million in each kidney, responsible for filtering blood, selective reabsorption, and excreting waste.

8. Card 8

   Which structure is located at the top of each nephron in the cortex and contains the glomerulus? A. Loop of Henle B. Proximal convoluted tubule C. Bowman's capsule D. Collecting duct

   C. Bowman's capsule. At the top of each nephron, in the cortex, the Bowman's capsule is located, and it contains the glomerulus.

9. Card 9

   The glomerular filtration barrier consists of three layers. Which of the following is one of these layers? A. Renal fascia B. Podocyte slit pores C. Renal medulla D. Transitional epithelium

   B. Podocyte slit pores. The three layers of the glomerular filtration barrier are the fenestrated capillary endothelium, basement membrane, and podocyte slit pores.

10. Card 10

    Which of the following substances is typically BLOCKED from passing through the glomerular filtration barrier? A. Water B. Glucose C. Large proteins D. Sodium ions

    C. Large proteins. The glomerular filtration barrier allows water and small molecules like glucose and ions to pass but blocks large proteins (e.g., albumin) and blood cells.

11. Card 11

    Tubular secretion involves substances moving from: A. The kidney tubule into the blood B. The blood into the kidney tubule C. The glomerulus into the Bowman's capsule D. The collecting duct into the ureter

    B. The blood into the kidney tubule. Tubular secretion is the process where substances are moved from the blood into the kidney tubule to eliminate unwanted materials and regulate pH.

12. Card 12

    The descending loop of Henle is characterized by being: A. Permeable to solutes but impermeable to water B. Relatively impermeable to solute but permeable to water C. Impermeable to both water and solutes D. Permeable to large proteins

    B. Relatively impermeable to solute but permeable to water. This characteristic is crucial for the concentration of urine as water leaves the filtrate in the descending limb.

13. Card 13

    What is the primary function of the urinary bladder? A. Filtration of blood B. Production of urine C. Storage of urine D. Reabsorption of water

    C. Storage of urine. The urinary bladder is a hollow muscular organ that serves as a storage organ for urine before it is expelled from the body.

14. Card 14

    In adults, when the bladder contains 200-250 ml of urine, what is the immediate physiological response? A. The external sphincter relaxes automatically. B. Stretch receptors send signals to the brain, sensing fullness. C. The internal sphincter contracts. D. Urine is immediately passed.

    B. Stretch receptors send signals to the brain, sensing fullness. When the bladder reaches this volume, stretch receptors activate, signaling the brain about bladder fullness, leading to the urge to micturate.

15. Card 15

    Which of the following is a sign or symptom commonly associated with a Urinary Tract Infection (UTI)? A. Decreased frequency of urination B. Pain on passing urine C. Increased appetite D. Weight gain

    B. Pain on passing urine. Common signs and symptoms of a UTI include pain on passing urine, urgency, increased frequency, suprapubic tenderness, and sometimes confusion or fever.
