Diagram of a Red Blood Cell
Adaptations:
- Biconcave shape: Increases surface area for gas exchange.
- No nucleus: Provides more room for hemoglobin.
- Flexible membrane: Allows passage through narrow capillaries.
Why is Carbon Monoxide an Issue?
Carbon monoxide (CO) is a dangerous gas because it binds with hemoglobin in red blood cells more strongly than oxygen does. This reduces the ability of red blood cells to carry oxygen to tissues, causing oxygen deprivation and potentially leading to serious health problems or death.
Symptoms of carbon monoxide poisoning include headache, dizziness, weakness, nausea, and confusion. Preventing CO exposure with detectors and ventilation is crucial.
What Do Red Blood Cells Do?
Red blood cells are responsible for transporting oxygen from the lungs to tissues throughout the body. They contain hemoglobin, a protein that binds to oxygen and facilitates its delivery. Additionally, red blood cells help transport carbon dioxide from tissues back to the lungs for exhalation.
