What type of immunity involves the production of memory cells for long-term protection?

Which cells carry out the adaptive immune responses?

What is the process called when hematopoietic stem cells divide and differentiate to give rise to blood cells?

Which type of immunity provides a rapid response but is not long-lasting?

Which white blood cells are known for their role in destroying infected or cancerous cells?

Which term describes the ability of hematopoietic stem cells to give rise to several different types of cells?

Macrophages have a primary role in immunity, functioning as first responders when a virus, bacterium, or allergen enters the bloodstream.

Macrophages prevent Malaria progression by destroying infected platelets.

Phagocytosis is a process carried out by macrophages to engulf and digest foreign particles.

There are two types of macrophages based on morphological characteristics: Small Macrophages and Large Granular Macrophages.

Lymphocytes account for about 2% of the total body weight in humans.

Leukocytosis is characterized by an elevated lymphocyte count in response to a bacterial infection.

Large Granular Lymphocytes have a higher nucleus to cytoplasm ratio compared to Small Lymphocytes.

The majority of lymphocytes in circulation are Large Granular Lymphocytes.

Macrophages are produced in primary lymphoid organs like the thymus and bone marrow at a rate of 10^9 per day.

In adults, lymphocytes represent about 20-40% of the total white blood cells present in circulation.
