The pathway of Grehlin from the stomach to the hypothalamus is as follows:
- travels through the blood to the brain
- crosses the blood-brain barrier
- binds to its receptors on the hypothalamus
<h3>What is Grehlin?</h3>
Grehlin is known as the hunger hormone.
It is released by the stomach when it is empty to signal the brain that it is time to eat.
The release of Ghrelin from the stomach stimulates the sensation of hunger, hence the common name, hunger hormone.
Once Grehlin is released into the blood the pathway it takes to the hypothalamus to signal hunger is given below:
- it travels through the blood to the brain
- it crosses the blood-brain barrier
- It binds to its receptors on the hypothalamus
- the hypothalamus acts through the nerves to stimulate hunger
In conclusion, the path of grehlin from the stomach is through the blood, and then it crosses the blood-brain barrier to bind to receptors on the hypothalamus, thus stimulating hunger.

I put the answer in the image attached
Answer:
Pyloric sphincter
Explanation:
The pyloric sphincter is known to be the muscle that connects stomach pylorus and the small intestine's duodenum. This muscle plays a very vital role in the digestion of food, and the muscle acts as though it is a valve controlling the flow of food that are partially digested from the stomach to the small intestine.
