ANATOMY

Detailed explanation-1: -Your immune system relies on specialized cells to fight off threats to your health. One of the most important ways your circulatory system supports your immune system is by carrying immune cells to their destinations. Without your blood vessels and arteries, these important cells could not do their job correctly.

Detailed explanation-2: -At the cardiovascular level, immune cells (activated either by a psychological or physical stressor) interact with endothelial cells, cardiac stromal cells and cardiomyocytes, which adapt their metabolism to support the ongoing inflammatory process (upper part right panel).

Detailed explanation-3: -They are attracted towards the infective agents, then surround and engulf them. Once inside the cell, these white cells then release chemicals that break the organism down and destroy it. Other white cells, called lymphocytes, target attacks in another way, by making antibodies.

Detailed explanation-4: -The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.
