A capillary that connects metaeriole directly with a venule is called as:
**Core Concept**
A capillary is a small blood vessel that allows for the exchange of oxygen, nutrients, and waste products between the blood and the tissues. The metarteriole is a small artery that branches off from an arteriole and supplies blood to a group of capillaries.
**Why the Correct Answer is Right**
The correct answer is a type of capillary that connects directly with a venule, which is a small vein that collects blood from the capillaries. This type of capillary is called a **hunting capillary** or a **arteriovenous anastomosis**. It allows for the direct exchange of blood between the arteriole and the venule, bypassing the capillary bed. This is especially important in areas such as the skin, where rapid cooling or warming is required.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not describe a type of capillary that connects directly with a venule.
* **Option B:** This option is incorrect because it describes a type of capillary that is not directly connected to a venule.
* **Option D:** This option is incorrect because it describes a type of capillary that is not directly connected to a venule.
**Clinical Pearl / High-Yield Fact**
In areas such as the skin, arteriovenous anastomoses allow for rapid temperature regulation by allowing blood to bypass the capillary bed and flow directly from the arteriole to the venule.
**Correct Answer:** . **Hepatic capillary**
