An increase in eosinophil count in the blood, often associated with allergic reactions and parasitic infections.

A decrease in eosinophil count in the blood, often seen with certain illnesses like measles and typhus or immunosuppressive treatments.

Lymphocytes are categorized by size: small (6-8µm), medium (8-12µm), and large (12-18µm).

Lymphocyte nuclei are eccentric (not centrally located) and have heterochromatin arranged radially, like 'wheel spokes'.

B-lymphocytes produce antibodies and are involved in humoral immunity.

T-helper cells regulate the immune response.

Monocytes differentiate into macrophages, which perform phagocytosis (engulfing) of pathogens and present antigens.

Platelets are crucial for blood clotting.

Blood transports nutrients, oxygen, and waste products; defends against infection; and regulates body temperature.

Blood consists of blood cells (erythrocytes, leukocytes, thrombocytes) and plasma.

Red blood cells; carry oxygen and carbon dioxide.

White blood cells; part of the immune system.

Blood platelets; essential for blood clotting.

The liquid part of blood; transports nutrients, waste, and blood cells.

The protein in red blood cells that carries oxygen.

The range of normal red blood cell counts for males and females.

Breakdown of old red blood cells in the spleen and liver.

Blood is found in blood vessels and hematopoietic organs.

A type of white blood cell (leukocyte) with a multi-lobed nucleus and granules that help fight infection.

Neutrophils contain both specific and non-specific granules. Specific granules contain antibacterial substances; non-specific granules are lysosomes (containing enzymes).

Basophils release histamine and heparin which activate inflammatory processes and prevent blood clotting.

Another type of white blood cell with irregular shaped nucleus and granules that stain basophilic; they are involved in allergies and inflammatory responses.

A type of white blood cell with a bi-lobed nucleus, and granules that stain strongly pink-orange. They are important for fighting parasites and certain allergic reactions.

Eosinophil granules contain substances like antihistamines, which help counter allergic reactions.

These are cells involved in phagocytosis, the process of engulfing and destroying foreign particles or pathogens.

An increased number of neutrophils in blood, often indicative of infection.
