Question

Specialized lymphatic capillaries called lacteals are

a) located primarily in the large intestine.
b) located throughout the body.
c) necessary for the transport of dietary lipids.
d) part of the fenestrated capillary group.
e) more numerous than blood capillaries.

Answer 1

Necessary for the transport of dietary lipids. (Ans. C)

Step-by-step explanation:

Lacteals are specialized lymphatic capillaries which helping in to absorb dietary fats that are present in the villi of the small intestine. With the help of bile, triglycerides is emulsified, and with the help of enzyme lipase, triglycerides is hydrolyzed, these (emulsified and hydrolyzed) results in the mixture of di, monoglycerides, and fatty acids.

The villi are finger shaped, and tiny in size which helping in to increase the surface area. Intestinal structure is known as lacteals which helps in the transport of glycerol, and fatty acids aside from the small intestine in the lymph.
