Which of these planes would show the heart, lungs, and liver in the same section?
Masteriza [31]
The answer to this question should be: coronal section

The heart is located near the lung but not near the liver. Heart location is much upper than the liver so it wasn't in the same Y plane. Heart also located on the left side, opposite of the liver on the right side which means they also located on the different axial plane. But heart and liver located in the front, which means they are in same Z plane position. That is why coronal section will be able to show them together.

What are some future treatments that are on the horizon?it about Cancer
kkurt [141]

Answer:

New discoveries in the treatment of cancer do not only centre on conventional medicine. In our haste to get to grips with a cure for cancer, natural products may be overlooked and dismissed in the fight against such an aggressive disease.

In December, the Academy of General Dentistry reported that a new study had found that simply swishing green tea around the mouth halts the growth of new oral cancer cells and breaks down and kills existing oral cancer cells. The antioxidants (polyphenols) in the tea work to remove the free radicals or oxidants and prevent gene mutations, and as an added bonus, the polyphenols can kill cancerous cells without harming normal cells and inhibiting their growth. Similarly, a chemical found in tomatoes may prevent or treat oral cancer and one derived from soybeans has been found to shrink abnormal growths that lead to cancer. While these are not cures, their activity may in the future lead to therapies that compliment conventional treatment modalities.

Perhaps combining ancient remedies with Western scientific advances is the way forward to finding an effective cure for cancer. Combrestatin – a cancer-fighting drug made from the bark of an African tree – is performing with dramatic effects in tests. The active ingredient extracted from the bark attacks the blood vessels that grow with tumors, while leaving normal blood vessels alone.
