In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.
Lymphangioma is often formed during fetal development because of a blockage and subsequent tangling in your lymphatic system. Your lymphatic system is an important part of your immune system which is where the bacteria and any other foreign substances are destroyed.
What is lymphangitis? Lymphangitis is an infection of the lymph vessels beneath your skin.
