Functions and Structure of Red Blood Cells and White Blood Cells

Functions and Structure of Red Blood Cells and White Blood Cells Student Name Institution Affiliation Course Number Instructor's Name Due Date Red Blood Cells (RBCs) Red Blood Cells( erythrocytes) are the most abundant cell type in the blood and play a vital role in the circulatory system (Reid & Mohandas, 2021). They transport oxygen from the lungs to various tissues and organs while removing carbon dioxide, a waste product produced during cellular respiration. Structure RBCs are unique in their structure and composition. Small, biconcave, disc-shaped cells provide a significant surface area-to-volume ratio. This shape allows for efficient gas exchange, as oxygen and carbon dioxide diffuse across their cell membrane more easily. Unlike most cells in the human body, RBCs lack a nucleus, mitochondria, endoplasmic reticulum, and other organelle
