Final Answer:
The journey of food through the digestive and circulatory systems involves the mouth, esophagus, stomach, small intestines, bloodstream, brain, and liver.
Step-by-step explanation:
1. **Mouth (Digestive System):**
- Food journey begins in the mouth where mechanical and chemical digestion occur.
- **Relevant Phrase from Question:** "Mouth"
2. **Esophagus (Digestive System):**
- The esophagus transports chewed food from the mouth to the stomach.
- **Relevant Phrase from Question:** "esophagus"
3. **Stomach (Digestive System):**
- The stomach further breaks down food through acid and enzymes.
- **Relevant Phrase from Question:** "stomach"
4. **Small Intestines (Digestive System):**
- Most digestion and nutrient absorption occur in the small intestines.
- **Relevant Phrase from Question:** "small intestines"
5. **Bloodstream (Circulatory System):**
- Nutrients from digested food enter the bloodstream for transport.
- **Relevant Phrase from Question:** "bloodstream"
6. **Brain (Circulatory System):**
- The circulatory system delivers nutrients to the brain for energy.
- **Relevant Phrase from Question:** "brain"
7. **Liver (Digestive and Circulatory System):**
- The liver processes nutrients, detoxifies blood, and produces bile.
- **Relevant Phrase from Question:** "liver"
In summary, the journey involves the coordinated effort of the digestive system (mouth, esophagus, stomach, small intestines) and circulatory system (bloodstream, brain, liver) to ensure effective digestion, absorption, and nutrient distribution.
