Answer:

Firstly, when we exercise, or do some activity (in this case football), we use more energy than usual...

The reason some of her body systems work faster than normal, is to keep the body working and in the equilibrium, so that she won’t get tired too fast.

Related to circulation, her blood flow increases, since she needs more oxygen to reach the muscles faster, due to the exercise/activity (Lactic acid builds up, so more oxygen is required.)

Her breathing increases to take in more oxygen(O2), and give out more carbon dioxide(CO2).

Her body respires more(respiration), both aerobically(with oxygen), and anaerobically(without oxygen), lactic acid builds up due to anaerobic respiration.

(Here, energy is released from glucose to generate a substance called lactic acid. ... Therefore anaerobic respiration cannot be used for a prolonged period of time without having damaging effects on a cell.)

When she inhales (Oxygen), it goes to the lungs, to the alveoli ( Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going)

In the Alveoli, diffusion takes place, this is where oxygen is diffused into the blood, and carbon dioxide is diffused (taken into) into the lungs.

Then we exhale, which gives out the carbon dioxide(CO2), this happens really fast, we also breathe so fast, this process happens within seconds.

Red blood cells contain something called haemoglobin, this combines with oxygen To form oxyhaemoglobin, then when the red blood cell reaches the muscle, it gives the oxygen, converting oxyhaemoglobin back to haemoglobin.

Heart: pumps blood faster (as I said before), to ensure oxygen gets distributed faster to where it’s needed

Answer:

If you measure by edge of the Sun's magnetic fields, the end is the heliosphere. If you judge by the stopping point of Sun's gravitational influence, the solar system would end at the Oort Cloud.

Q6.7. During many epidemics, health-care professionals emphasize the importance of

Serga [27]

During many epidemics, healthcare professionals emphasize the importance of community mitigation strategies, such as wearing masks, frequent hand-washing, and social distancing because these strategies help reduce transmission even when drug-based treatments and vaccines are unavailable.

It is of vital importance in cases of epidemics to implement strategies such as:

Hand-washing
Wearing masks
Social distancing

in order to better protect our communities and ourselves.

Frequent hand-washing serves to eliminate the presence of a pathogen from the surface of your hands, reducing the risks that it will find entry into your organism or land on a surface with which others will come into contact. Should you or someone else contract the pathogen anyways, wearing a mask can help to reduce or deny the possibility of transmitting the disease.

Finally, should both previous measures fail, meaning that the virus or pathogen has infected an individual and penetrated the masks, social distancing can act as a final barrier that the pathogen will rarely be able to surpass, given that most pathogens cannot remain airborne over large distances.

For these reasons, healthcare professionals emphasize the importance of these strategies because they help reduce transmission until vaccines or drug-based treatments become available and herd immunity can be reached.
