The Immune System: An Overview

The immune system is our body's defense mechanism against infectious organisms and other invaders. It consists of a network of cells, tissues, and organs that work together to protect us from diseases. This intricate system includes:

• White blood cells: The primary warriors of our immune response, including lymphocytes (B cells and T cells) and phagocytes.
• Lymphatic system: A network of vessels and nodes that transport immune cells throughout the body.
• Bone marrow: The site where immune cells are produced.
• Spleen and thymus: Organs that play crucial roles in the maturation and activation of immune cells.

When functioning optimally, our immune system can effectively identify and neutralize harmful pathogens. However, various factors, including stress, diet, and lack of sleep, can compromise its efficiency, leading to increased susceptibility to infections.

How Vitamins Support Immune Health

Vitamins play a pivotal role in supporting and modulating the immune system. They help promote the development and function of immune cells, enhance the body's ability to respond to infections, and reduce inflammation. While a balanced diet rich in fruits, vegetables, whole grains, and lean proteins is essential for overall health, certain vitamins stand out for their immune-boosting properties.
