describe the ventricular systole in the cardiac cycle
Explanation:
Systole represents the time during which the left and right ventricles contract and eject blood into the aorta and pulmonary artery, respectively. During systole, the aortic and pulmonic valves open to permit ejection into the aorta and pulmonary artery. The atrioventricular valves are closed during systole, therefore no blood is entering the ventricles; however, blood continues to enter the atria though the vena cavae and pulmonary veins.
What are the avantages of an MRI scan over an xray?
Answer:
One big advantage to an MRI scan is that there is no exposure to radiation as in the case with X-rays, CT scans, and PET scans. This means MRI can be used more safely on people who are particularly vulnerable to the effects of radiation, such as pregnant women and babies.
MRI also has the advantage over X-ray because it can identify swelling and inflammation. It can show both three-dimensional and cross-sectional images of the body.
Imagine you have your own blog. You want people to know the truth about teens and drugs. Write a paragraph to post on your blog that explains that most teens do not use tobacco, alcohol, or other drugs. PLS HELPP
Answer:
Although it is true that the use of recreational drugs, especially tobacco, alcohol or cannabis, is relatively common among adolescents, it is also true that the percentages in which this situation occurs do not exceed 20% of the total number of adolescents of the country. In other words, only 1 in 5 children under 18 years of age regularly use any of these three substances, while 80% stay completely away from their use. In this way, it is a concept that undergoes a generalization that is not true, but on the contrary a fallacious attribution to a whole group of people.

You are attempting to replace the oxygen cylinder in your truck. After removing the regulator from the old cylinder, removing the old cylinder, and placing the new cylinder in the oxygen compartment, you attempt to connect the regulator. The new cylinder has a yellow stripe around it instead of a green one but was stored with the green cylinders. You are unable to get the regulator to seat properly and it will not turn. You should:
A. remove the cylinder and get a green cylinder
B. put the old cylinder back on the truck
C. attempt to force the regulator onto the cylinder
D. replace the oxygen regulator with a new one
Answer: A. remove the yellow cylinder and get a green cylinder
Explanation:
Since new cylinder has a yellow stripe around it instead of a green one but was stored with the green cylinders, then this will probably be the reason for the inability to get the regulator to seal properly and not turn.
Therefore, the best thing to do is to remove the yellow cylinder and get a green cylinder. This will fit on properly and then make it turn. Therefore, the correct option is A.

Why might humans not have widespread regeneration abilities?
Answer:
Humans have some stem cells, but those cells are not easily available to help with healing. Most other mammals are the same, so they aren't good at regeneration either. Amphibians and some fish have stem cells that are more easily available, and are usually pretty good at regeneration.

During what years does the calories you need begin to decrease?
40s
20s
50s
30s
Answer:
20
Explanation:
As we age, our metabolism slows and the rate at which we break down food decreases by 10 percent each decade after age 20. Therfor, the 20's.
Calories are the energy required by the body to maintain metabolic reactions. In the 20s the required calories by the body start decreasing. Thus, option b is correct.
What are calories?In nutrition, calories are defined by the energy provided by the food components carbohydrates, fats, vitamins, fibers, proteins, etc. The energy is provided in the body by the breakdown of the food substances.
The metabolic rate of the body starts decreasing with age which results in a decrease in calories. As the age increases the metabolism slows down and is especially seen around the 20s.
The metabolic rate is very high in the first 20 years of life but decreases as the age increases resulting in low energy leading to tiredness and fatigue.
Therefore, option b. the calories begins decreasing around 20s is correct.

1. How do you know when someone is choking?
2. Where do you place your fist for the Heimlich Maneuver?
3. How do you compress the abdomen?
4. How long do you do the thrusts?
5. Where do you place fist if you are performing the Heimlich Maneuver on a pregnant woman?
Answer:
um ok well this is some good stuff here
Explanation:
so for the 1rst question it is by the way the body thrashes when the brain realizes it can get any oxygen plus they start to weez and well I am in CPS and the placement here restrained me to the point where I was literally on the brink of passing out or dying I dont really know to be sure but um so that is 2 ways you can tell that they are choking.
for the 2nd one um i have this .To perform abdominal thrusts (Heimlich maneuver) on yourself, place a fist slightly above your navel. Grasp your fist with the other hand and bend over a hard surface, or for others
Have the victim stand and face away from you, then wrap your arms around their waist from behind. Then, repeat the following steps as needed: Make a fist and place the side with your thumb in their upper abdomen, underneath their sternum, or ribcage.
the 3rd is To either side of the rectus abdominis are the other three layers of abdominal muscles. The deepest of those layers is the transversus abdominis, which has fibres that run perpendicular to the rectus abdominus; the transversus abdominis acts to compress and support the abdomen and provides static core stabilization.
Perform between six and 10 abdominal thrusts until the blockage is dislodged
Position your hands a little bit higher than with a normal Heimlich maneuver, at the base of the breastbone, just above the joining of the lowest ribs.
Proceed as with the Heimlich maneuver, pressing hard into the chest, with a quick thrust.

A truck was carrying a substance in a tank. The molecules of that substance were moving away from each other . The truck parked overnight in a place where energy transferred out of the substance
Answer:
The missing parts of the question and options are:
In the morning, the substance was a gas. How were the molecules moving in the morning?
a. They were moving more slowly away from each other.
b. They were moving more slowly in place.
c. They were moving more slowly around each other.
d. They were moving more quickly around each other.
The substance cooled down, but why was it still a gas?
a. The molecules are so attracted to each other that they need much more energy transferred in to change phase.
b. The molecules are so attracted to each other that they need more energy transferred out to change phase.
c. The molecules are not very attracted to each other, so they need much more energy transferred out to change phase.
d. The molecules are not very attracted to each other, so they need much more energy transferred in to change phase.
The answers are:a. They were moving more slowly away from each other
c. The molecules are not very attracted to each other, so they need much more energy transferred out to change phase.
Explanation:
If the substance is a gas, the molecules collide with each other, and they drift apart. The intermolecular forces between molecules are weak. As a result, when they bump with each other, they do not get attached. Usually, in a gas, the molecules move fast in all directions, and they gain energy with their collisions. However, in this case, they move slowly because the substance lost energy overnight. If the substance loses more energy, it becomes a liquid, and its molecules would be more attracted to each other.

How many chambers in the Hart?
(Pringles)
Explanation:
The heart has four chambers: two atria and two ventricles.
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
The right ventricle pumps the oxygen-poor blood to the lungs.
The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
Answer:
4Explanation:
The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
