Understanding Blood Cells and Their Functions in the Circulatory System

Blood is comprised of cells and plasma that circulate within the closed circulatory system. The formed elements include erythrocytes, platelets, and leukocytes, each playing vital roles in oxygen transport, defense against infection, and nutrient distribution throughout the body. The hematocrit esti

Understanding White Blood Cells and Their Classification

White blood cells (WBCs), or leukocytes, are vital elements of the blood responsible for protecting the body against invading organisms. They are classified into granulocytes (neutrophils, eosinophils, basophils) and agranulocytes (monocytes, lymphocytes), each playing specific roles in the immune s

Understanding WBC Differential Count in Blood Analysis

WBC (white blood cell) count is essential in assessing a patient's health. A differential count helps determine the percentage of different types of white blood cells. This analysis can provide important insights into various health conditions like infections, allergies, and systemic illnesses. The

Role of Adhesion Molecules in Immune Response to SARS-CoV-2 Engagement

Engagement of SARS-CoV-2 triggers the complement system and TLR 7 in neutrophils and macrophages, leading to the release of inflammatory cytokines and chemotactic factors. This results in the upregulation of adhesion molecules on blood capillary endothelial cells and leukocytes, facilitating leukocy

Overview of Blood and Hematology: Functions and Composition

The human body consists mostly of water, with blood making up approximately 8% of body weight. Blood is composed of plasma and formed elements, including red blood cells (erythrocytes), white blood cells (leukocytes), and platelets. Plasma, the liquid part of blood, contains various proteins such as
