Match the following events to their stage of respiration internal respiration external respiration pulmonary ventilation gas transport inspiration & expiration gas transfer at the alveoli as movement through the body gas transfer at the blood capillaries

## Step 1<br />The first step is to understand the terms and their meanings in the context of respiration.<br /><br />### **External Respiration**<br />This refers to the process of gas exchange between the air in the lungs and the blood in the capillaries. This process occurs in the alveoli of the lungs.<br /><br />### **Pulmonary Ventilation**<br />This is the process of moving air in and out of the lungs. This process involves two stages: inspiration (inhaling) and expiration (exhaling).<br /><br />### **Gas Transport**<br />This refers to the movement of gases (oxygen and carbon dioxide) through the bloodstream to and from the tissues of the body.<br /><br />### **Internal Respiration**<br />This is the process of gas exchange between the blood in the capillaries and the tissues of the body.<br /><br />## Step 2<br />Next, we match each event to its corresponding stage of respiration.<br /><br />- **External Respiration**: This corresponds to the gas transfer at the alveoli.<br />- **Pulmonary Ventilation**: This corresponds to the inspiration & expiration.<br />- **Gas Transport**: This corresponds to the gas transport as movement through the body.<br />- **Internal Respiration**: This corresponds to the gas transfer at the blood capillaries.
