Q1. What is a lacteal?
- A gland within the stomach
- A blood sinusoid within the liver
- An artery within the mesentery
- A lymphatic capillary within an intestinal villus
Q2. Where are lacteals located?
- Inside the renal glomeruli
- Within small-intestinal villi
- Within gastric pits
- Within colonic taeniae
Q3. What is the principal absorptive role of lacteals?
- Filtration of urine
- Secretion of bile
- Absorption of oxygen into arterial blood
- Absorption of chylomicron-rich lipid into lymph
Q4. Which cells package absorbed dietary lipids into chylomicrons before they enter lacteals?
- Enterocytes
- Podocytes
- Osteocytes
- Hepatocytes
Q5. What is lipid-rich intestinal lymph called?
- Chyle
- Synovial fluid
- Plasma
- Bile
Q6. Which intestinal structure contains both blood capillaries and a central lacteal?
- Anal column
- Gastric ruga
- Appendiceal orifice
- Intestinal villus
Q7. Which nutrients are especially associated with transport through lacteals?
- Electrolytes only
- Most monosaccharides
- Long-chain dietary lipids
- Most amino acids
Q8. Lymph from lacteals eventually enters which larger lymphatic vessels?
- Renal arteries
- Hepatic portal veins directly
- Common bile ducts
- Mesenteric lymphatic vessels
Q9. Which major central lymphatic pathway ultimately receives chyle from intestinal lacteals?
- Thoracic duct pathway
- Right lymphatic duct exclusively
- Inferior vena cava directly
- Hepatic artery
Q10. Which statement best describes lacteals?
- They secrete digestive enzymes
- They are specialized lymphatic capillaries for intestinal lipid transport
- They are arteries supplying the villi
- They are venous valves
