When released into bloodstream, epinephrine increases heart rate, constricts blood vessels, dilates air passages and participates in the fight-or-flight response of the sympathetic nervous system. Norephinephrine does the same and increases the brain's oxygen supply.

When epinephrine is released into the bloodstream?

When epinephrine is released into the bloodstream, it can increase heart rate, constrict blood vessels, dilate air passages in the lungs, and mobilize glucose for energy. This hormonal response is part of the fight-or-flight reaction to stress or danger.


What is the function of alveoli in the respiratory system?

The alveoli are tiny air sacs in the lungs where oxygen is taken in and carbon dioxide is released during the process of breathing. They are responsible for the exchange of gases between the lungs and the bloodstream, allowing oxygen to enter the body and carbon dioxide to be removed.


Where does breathing take place?

From my physiology class...if you mean the gas exchange (CO2-O2), it occurs at the alveoli level. These are part of the bronchioles which are branches of the bronchi which are branches of the trachea. Alveolis are located within the lungs. Breathing takes place in many areas. All of the areas of entry where oxygen enters the body is involved such as the mouth and nasal passages, the trachea, the bronchi, the lungs, even the blood stream because that is where the actual exchange of these gases occur.


Where in the body are calcium and phosphorus stored before being released into the bloodstream?

Calcium and phosphorus are primarily stored in the bones and teeth. When needed, they can be released from these storage sites into the bloodstream to maintain their levels for various bodily functions.


What vessel does fat reenter the bloodstream through?

Fat reenters the bloodstream through lymphatic vessels known as lacteals. These vessels are located in the small intestine and absorb dietary fats in the form of chylomicrons, which are then released into the bloodstream to be delivered to tissues for energy or storage.

When stress hormones are released into the bloodstream which of these physical responses occur?

When stress hormones are released into the bloodstream, physical responses can include increased heart rate, heightened alertness, faster breathing, and a temporary increase in energy as part of the fight-or-flight response triggered by the sympathetic nervous system.


When stress hormones are released into the bloodstream what physical responses occurs?

The heart beats more rapidly, blood flow to the brain increases.


Where in our breathing system does the changes of oxygen and carbon dioxide dioxide happen?

The exchange of oxygen and carbon dioxide occurs in the alveoli of the lungs. Oxygen is taken up from the air into the bloodstream, and carbon dioxide is released from the bloodstream into the air in the alveoli during respiration.

How does breathing take place?

Breathing is the process of inhaling oxygen and exhaling carbon dioxide. When we inhale, our diaphragm and chest muscles contract, expanding the lungs and creating negative pressure that draws in air. Oxygen from the inhaled air is absorbed into the bloodstream, while carbon dioxide is released when we exhale.
