Answer:
The correct answer will be option-A.
Explanation:
The cardiac cycle of the heart is divided into two phases: contraction (systole) and relaxation (diastole).
The atria and ventricles of the heart contract simultaneously in response to the impulse generated in the SA node. The contraction of the atria and ventricles push the blood or pumps the blood.
The atrial systole pumps blood to ventricles whereas the ventricular systole pumps blood to the body parts.
Thus, option-A is the correct answer.
COPD, emphysema, bronchitis , and asthma. Chronic obstructive pulmonary disease (COPD), which incorporates chronic bronchitis.
<h3>What about chronic obstructive pulmonary disease?</h3>
- COPD symptoms include persistent coughing or wheezing.
- Excessive sputum or phlegm.
- Respiration difficulty.
- The signs and symptoms include wheezing, expulsion mucus (sputum), and trouble breathing.
- It's frequently brought on by prolonged exposure to irritant gases or particulates, most often from cigarette smoke.
- Heart disease, carcinoma , and a variety of other diseases are more likely to occur in people with COPD.
- In around 9 out of each 10 cases, smoking is regarded to be the first cause of COPD.
- The lining of the lungs and airways can get damaged by the toxic compounds in smoke.
- Quitting smoking can help stop the deterioration of COPD.
- Short-acting bronchodilator inhalers are the initial line of therapy for the bulk of COPD patients.
- Breathing is formed easier by bronchodilators, which relax and expand the airways.
- Short-acting bronchodilator inhalers are available in two varieties: beta-2 agonist inhalers, like salbutamol and terbutaline.
- For those with chronic obstructive pulmonary disease (COPD) who have (or are in danger for) hypercapnia, an excessive amount of oxygen can be harmful.
- Patients with hypercapnia are frequently over oxygenated, despite established standards and acknowledged danger.

I'm not sure that this is 400 words but this is what I came up with.
Given basic nutritional information, the daily values are set for a diet of 2000 calories.
The daily values represent the appropriate intake levels for a 2000 calorie diet. This is not to say that every person should have a 2000 calorie intake daily, but it is used by the USDA to establish a benchmark to be used.
For example, a person who has a daily calorie intake of 2000 calories should, according to the USDA, consume about 50 grams of protein per day. These numbers can then be adjusted proportionally for each individual based on their calorie intake.
