Understanding the basics and functionality of the immune system is essential to comprehend how cannabis may impact its functioning.

Primary Functions of the Immune System

The immune system serves several primary functions, including:

1. Protection: The immune system acts as a barrier, preventing the entry of harmful pathogens into the body.
2. Identification: It recognizes and identifies foreign substances, distinguishing them from the body’s own cells and molecules.
3. Elimination: The immune system mounts an immune response to eliminate pathogens and infected cells from the body.
4. Memory: It has the ability to remember and recognize previously encountered pathogens, allowing for a quicker and more efficient response upon re-exposure.

Key Components of the Immune System

The immune system consists of various components, each playing a crucial role in its overall function. These components include:

1. White Blood Cells: White blood cells, also known as leukocytes, are the primary cells involved in immune responses. They are categorized into two main types: innate immune cells (such as neutrophils, macrophages, and natural killer cells) and adaptive immune cells (such as T cells and B cells).
2. Lymphoid Organs: Lymphoid organs, including the thymus, bone marrow, spleen, and lymph nodes, serve as sites for the production, maturation, and activation of immune cells.
3. Antibodies: Antibodies, also known as immunoglobulins, are proteins produced by B cells. They bind to specific antigens (foreign substances) and help in their neutralization or elimination.
4. Cytokines: Cytokines are signaling molecules that coordinate immune responses. They regulate the growth, activation, and function of immune cells.

Immune System Disorders

The immune system is not infallible and can sometimes malfunction, leading to immune system disorders. These disorders can manifest in various ways, including:

1. Autoimmune Diseases: In autoimmune diseases, the immune system mistakenly attacks and damages the body’s own cells and tissues. Examples include rheumatoid arthritis, lupus, and multiple sclerosis.
2. Immunodeficiency Disorders: Immunodeficiency disorders result in a weakened or impaired immune system, making individuals more susceptible to infections. Conditions such as HIV/AIDS and primary immunodeficiency disorders fall into this category.
