Readers please note that the focus in
our blog reports has become the small intestine the centre point of the HIV
infection.
Here the nutrients pass from the
stomach to be absorbed through the villi of the small intestine. These are the
myriads of small protrusions on the gut wall that increase the surface area for
absorption.
Inside the villi is a network of
blood capillaries that leads to the hepatic portal vein. Along this path the
nutrients are carried to the liver. As
well there are lymph capillaries that lead to the vessel that carries lymph to
the heart and known as lymphatics.
On absorption through the gut wall, nutrients pass on to the liver through the hepatic
portal vein. Fats do not travel along this route
but pass to the lymphatics to connect to the major heart vein the vena cava and
carried to the heart.
The first major points of accumulation
of fats are the lymph vessels, vena cava and heart. People who consistently eat
fats will suffer the risk of heart attack as the fat clogs the arteries of the
heart.
If we go to a food shop in Papua New Guinea, we will find trays of sheep hearts for sale. On top of each heart and the two vena cava, there is a layer of fat. And sheep only eat grass !!
HIV follows the same path but enters the lymph system lower down at the genitals and travels up to the heart to be shepherded down through the abdominal artery to the CD4 cells that guard the small intestine. Replication takes place in the CD4 cells of the small intestine.
The small intestine is the epicentre of the HIV attack and the loading of fat into the body.
