Trying to take less stress off buy not doing so much .
Hope this helps !!!
Explanation:
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.
Music has a very strange, psychological effect on people. Honestly, music is what keeps me trucking through school. But usually theres only a couple ways to get people to want to do something. One is Almost like mass hysteria, if you surround them with people who are excited to play the sport, and get them in a chant, they're going to get "pumped" to do it as well. To my knowledge, the other I wanted to cover, is music. If you've ever been on Spotify, you'll see they have "Work-out playlists." This is supposed to "hype you up" to power through the pain, just like if you wanted to relax you'd listen to classical, or orchestra music.
Answer:
A. epinephrine
Explanation:
Bronchial constriction usually involves the tightening of the smooth muscles which surrounds the tube-like bronchial airways. This occurs via extra mucus production, spasming of smooth muscles, or swelling/inflammation of layers within bronchi or bronchioles. Bronchial constriction typically results in symptoms of wheezing, coughing and shortness of breath.
This can be treated via the use of the hormone epinephrine, a bronchiodilator. For some cases like asthma, epinephrine in small aerosolized (inhaled) doses can lead to the <em>temporary</em> relief of symptoms. Epinephrine acts by making bronchial tubes wider to allow the passage of air.
In the body, smooth muscle cells in the veins, arteries and heart are under the control of epinephrine receptors called β2 receptors. Epinephrine binding to the receptor triggers a cell signalling cascade that activates β2 receptors to dilate smooth muscle in the lungs.
Here's how-
- Calcium is essential to mediating muscle cell signalling and thus contraction
- in the lungs, epinepherine-β2 receptor binding leads to enzyme activation (adenylyl cyclase)
- conversion of the energy molecule ATP to the secondary messenger molecule cyclic AMP.
- cAMP inhibits the activity of the enzyme <em>myosin light chain kinase </em>(MLCK) in smooth muscle
- ∴ the enzyme remains inactive and the muscles relax
<em>Summary:</em><em> epinephrine → muscle relaxation →</em><em> bronchial dilation (reduced diameter) </em><em>→ decreased respiratory distress → easier breathing.</em>
Answer:
Chronic stress may increase your risk of developing type 2 diabetes. The rush of hormones, rapid breathing, and increased heart rate can also upset your digestive system. You’re more likely to have heartburn or acid reflux thanks to an increase in stomach acid. answer is A
