Which of the following is the correct sequence of the cardiac cycle?
a. SA node, AV node, the bundle of HIS, Purkinje fibers
b. AV node, SA node, the bundle of HIS, Purkinje fibers
c. The bundle of HIS, AV node, SA node, Purkinje fibers
d. Purkinje fibers, SA node, AV node, the bundle of HIS
Answer:
A. SA node, AV node, the bundle of HIS, Purkinje fibers
Explanation:
1. The conduction system of the heart -nodal system- is what allows myocardial contraction, which translates into heartbeat and pumping of blood.
This conduction system begins in the sino-atrial node (SA), which is located in the upper portion of the right atrium, and is regulated by the autonomic-sympathetic and parasympathetic nervous system.
The impulse generated in SA passes to the atrioventricular node (AV) that is located in the interventricular septum (IVS).
From AV, impulse passes to the His-Purkinje system, formed by the bundle of His, which runs along the IVS and is divided into two branches, right and left.
Purkinje fibers are born from each of the bundles of His bundle, and are distributed through the right and left ventricles.
2. As a result of the depolarization that occurs in the atrioventricular node - which undergoes a brief interruption in its path - depolarization continues in the bundle of His, which runs through the rest of the interventricular septum to divide into two branches, the right and the left.
The left branch is usually subdivided into three fascicles, the left anterior, left posterior and a central branch. Purkinje fibers are born from each of these branches and fascicles, which stimulate myocardial contraction.
3. Ventricular systole consists of contraction of the myocardium, which leads to boost blood contained in the ventricles to the lungs or general circulation. In this phase of the cardiac cycle, the semilunar valves - which allow access to the pulmonary and aortic arteries - open, which produces the second cardiac noise.
Other events that occur during systole are the increase in ventricular pressure and the closure of the atrioventricular valves (AV), to prevent ventricular blood from returning to the atria.

Answer:
Lung Cancer Risk Factors
A risk factor is anything that increases a person’s chance of getting a disease such as cancer. Different cancers have different risk factors. Some risk factors, like smoking, can be changed. Others, like a person’s age or family history, can’t be changed.
But having a risk factor, or even several, does not mean that you will get the disease. And some people who get the disease may have few or no known risk factors.
Several risk factors can make you more likely to develop lung cancer. These factors are related to the risk of lung cancer in general. It’s possible that some of these might not apply to small cell lung cancer (SCLC).
Risk factors you can change
Tobacco smoke
Smoking is by far the leading risk factor for lung cancer. About 80% of lung cancer deaths are thought to result from smoking and this number is probably even higher for small cell lung cancer (SCLC). It’s very rare for someone who has never smoked to have SCLC.
The risk of lung cancer for people who smoke is many times higher than for people who don't smoke. The longer you smoke and the more packs a day you smoke, the greater your risk.
Cigar smoking and pipe smoking are almost as likely to cause lung cancer as cigarette smoking. Smoking low-tar or “light” cigarettes increases lung cancer risk as much as regular cigarettes. Smoking menthol cigarettes might increase the risk even more since the menthol may allow people to inhale more deeply.
Secondhand smoke
If you don’t smoke, breathing in the smoke of others (called secondhand smoke or environmental tobacco smoke) can increase your risk of developing lung cancer. Secondhand smoke is thought to cause more than 7,000 deaths from lung cancer each year.
If you or someone you care about needs help quitting, see How To Quit Smoking or Smokeless Tobacco or call the American Cancer Society at 1-800-227-2345
Exposure to radon
Radon is a naturally occurring radioactive gas that results from the breakdown of uranium in soil and rocks. You can’t see, taste, or smell it. According to the US Environmental Protection Agency (EPA), radon is the second leading cause of lung cancer in this country, and is the leading cause among people who don't smoke.
Outdoors, there is so little radon that it is not likely to be dangerous. But indoors, radon can be more concentrated. Breathing it in exposes your lungs to small amounts of radiation. This may increase a person’s risk of lung cancer.
Homes and other buildings in nearly any part of the United States can have high indoor radon levels (especially in basements).

Among the postnatal care currently offered, therapeutic hypothermia has been shown to be a safe and effective method in reducing mortality, motor and cognitive sequelae.
Therapeutic hypothermiaThe purpose of therapeutic hypothermia is to establish guidelines for the safe and effective performance of therapeutic hypothermia in neonates with moderate and severe hypoxic-ischemic encephalopathy, based on recent clinical trials, reviews and meta-analyses.

Ozone is a gas composed of three atoms of oxygen (O3). Ozone occurs both in the Earth's upper atmosphere and at ground level. Stratospheric ozone, is considered good ozone and occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun's harmful ultraviolet rays. Tropospheric, or ground level ozone, is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds. This happens when pollutants emitted by cars, power plants, chemical plants, and other sources chemically react in the presence of sunlight. Ozone at ground level is the main ingredient in smog.
Children are at greatest risk from exposure to ozone because their lungs are still developing and they are more likely to be active outdoors when ozone levels are high, which increases their exposure. Because of this, we would expect these children to be more likely to develop what respiratory condition?
A) COPD
B) Asthma
C) Emphysema
D) Lung cancer
Children are at greatest risk from exposure to ozone because their lungs are still developing and they are more likely to be active outdoors when ozone levels are high, which increases their exposure. Children are also more likely than adults to have asthma.
