Answer:
Our bodies deliberately send more blood to an erectile tissue between the two nostrils to increase its size and direct the air flowing through one of the nostrils. After a few hours, the airflow switches to the other nostril.
Explanation:
I’ll bet most people don’t realize that when you breathe through your nose, you do so more from one nostril than the other and your body knows to switch to the other nostril every few hours. I had no idea. I’m only aware of any difference in my nostrils when I’m congested!
This nasal cycle is controlled by the autonomic nervous system which also controls things we don’t think about like heart rate and breathing
Why do we do this? Some scientists believe the alternating airflow allows each nostril to maintain optimal moisture levels so no one side gets dried out. It may also protect against respiratory infections or allergies.
Others believe it’s tied to our olfaction or sense of smell. It’s possible that the quicker and slower airflow in each nostril optimizes us to the vast range of smells. Some smells take longer to detect and transmit to the brain.

The rate of glycogen breakdown is a muscle preparation containing glycogen phosphorylase is treated with (a) phosphorylase kinase increases and ATP; (b) PP1 decreases; (c) epinephrine increases.
Glycogen
In animals, fungi, and bacteria, glycogen is a multibranched polysaccharide of glucose that acts as a source of energy storage. The primary form of glucose storage in the body is represented by the polysaccharide structure.
One of two types of energy reserves, glycogen is used for short-term storage, while the other type is triglyceride storage in adipose tissue (body fat), which is used for long-term storage. Glycogen is predominantly produced and stored in the liver and skeletal muscle cells of humans. Glycogen can account for 5–6% of the liver's fresh weight, and an adult liver weighing 1.5 kg can hold about 100–120 grams of glycogen.
