How do water, fatty acids, and glycerol enter the blood capillaries and lymphatic system?
Understand the Problem
The question describes the process of how substances like water, fatty acids, and glycerol enter the bloodstream and lymphatic system. It mentions that water enters the blood capillaries, while fatty acids and glycerol enter through lacteals, which then carry them to the lymphatic system. We need to understand the mechanisms and pathways involved in the absorption of these nutrients.
Answer
Water goes into blood capillaries, while fatty acids and glycerol enter the lymphatic system via lacteals.
Water enters blood capillaries directly. Fatty acids and glycerol are absorbed into the lacteals, which transport them through the lymphatic system before entering the bloodstream.
Answer for screen readers
Water enters blood capillaries directly. Fatty acids and glycerol are absorbed into the lacteals, which transport them through the lymphatic system before entering the bloodstream.
More Information
Lacteals are lymphatic capillaries located in the villi of the small intestine, and are specialized for absorbing fats. The lymphatic system is a network of vessels that transports fats and fat-soluble vitamins, eventually draining into the bloodstream.
Tips
A common mistake is thinking that fats directly enter the bloodstream like other nutrients. It's important to remember the role of lacteals and the lymphatic system in fat absorption.
