What are lacteals? What is their function?

• Lacteals are specialized lymphatic capillaries in the small intestine. Their function is to absorb dietary fats (lipids) and fat-soluble vitamins. They transport fats as chyle.

• Lacteals are blood vessels in the liver. Their function is to filter toxins from the blood.

• Lacteals are nerve cells in the brain. Their function is to transmit electrical impulses.

• Lacteals are muscle fibers in the heart. Their function is to pump blood throughout the body.

Where do the thoracic duct and right lymphatic duct empty?

• Thoracic duct drains most of the body and empties into the left subclavian vein.

• Thoracic duct drains most of the body and empties into the right subclavian vein.

• Thoracic duct drains most of the body and empties into the left jugular vein.

• Thoracic duct drains most of the body and empties into the right jugular vein.
