Explain briefly the gaseous transport in human beings.

Explanation

**Step-by-Step Solution:**

1. **Introduction to Gaseous Transport:**
Gaseous transport in human beings primarily involves the movement of two main respiratory gases: oxygen (O2) and carbon dioxide (CO2).

2. **Transport of Oxygen:**
- About **97% of oxygen** is transported in the blood by binding to hemoglobin, a protein found in red blood cells. This bound form of oxygen is known as **oxyhemoglobin**.
- The remaining **3% of oxygen** is transported in a dissolved form in the blood plasma.
