Answer :
The affected portal triad vessel that receives blood from the intestine for detoxification is the d. Portal Venule.
d. Oblique Layer is the additional layer of smooth muscle in the stomach's muscularis externa.
1. Portal Hypertension and the Portal Triad
Portal Hypertension refers to increased blood pressure in the portal venous system, often due to liver diseases, thrombosis, or cirrhosis.
The portal triad consists of three key structures:
- Hepatic Arteriole: It supplies oxygenated blood to the liver from the heart.
- Portal Venule: It carries nutrient-rich blood from the gastrointestinal tract to the liver for detoxification and processing.
- Bile Duct: It collects bile produced by the liver for digestion.
2. Muscularis Externa of the Stomach
The muscularis externa is a critical layer in the gastrointestinal tract which aids in the movement of food through rhythmic contractions. Typically, it consists of two main layers:
- Circular Layer: This layer is responsible for constricting the gut and mixing food.
- Longitudinal Layer: This layer shortens the gut and moves food further along the digestive tract.
In the stomach, there exists an additional layer known as the Oblique Layer. This third layer allows for more powerful churning motions of the stomach, which is essential for breaking down food and mixing it with gastric juices for digestion.
