Does cholesterol float free in the bloodstream?
Usually not. They are carried by lipoproteins called chylomicrons.
What is the function of chylomicrons?
Chylomicrons and large lipoprotein particles that consist of triglycerides, phospholipids, cholesterol and proteins. Their function is to transport dietary lipids from the intestinal epithelial cells to the liver or other locations around the body.Chylomicrons transport fats and cholesterol from the intestine into the liver, then into the bloodstream
What transport carriers enable fat and cholesterol to travel through the blood and lymph?
chylomicrons pg 147 :)
In the small intestines fatty acids cholesterol and glycerides combine in epithelial cells to form complex structures are called?
chylomicrons
What else other than the blood carries nutrients throughout the body?
The lacteals, or lymph vessels do. The blood absorbs amino acids and sugars from the small intestine, while lacteals absorb triglycerides (fat), cholesterol, and the fat-soluble vitamins. These three nutrients are built up into chylomicrons in the epithelium of the small intestine, and it is these chylomicrons that are taken up by the lacteal.
How do villi help the lymphatic system?
Lacteals collect fats by absorbing chylomicrons (consisting of 90% triglycerides, 5% cholesterol, 4% phospholipids, 1% protein) in the small intestines and transports them to cardiovascular circulation. Chylomicrons travel through the lymphatic system via the thoracic duct to the bloodstream.
