elena55 [62]3 years ago
4 0

Answer:

The correct answer will be option A.

Explanation:

The atrioventricular valve is one of the four valves present in the heart the function of which is to stop the back flow of the blood from the ventricles to the atrium.  

These valve opens and closes in response to the change in the pressure of the blood in atrium and ventricles.  The valve opens when blood is pumped form the atrium to ventricles which causes the papillary muscles to relax while the valve closes when the ventricles push the blood to the arteries. This causes the papillary muscle to contract which causes the chordate tendineae to create tension ad close the valve.

Thus, option A is the correct answer.

Of the total amount of glucose energy consumed by the body each day, about what percentage is used by the brain and nerve cells?
Alexeev081 [22]

Of the total amount of glucose energy consumed by the body each day, about 20% is used by the brain and nerve cells.

The brain constitutes about 2% of the total body but it is one of the main consumers of energy derived from glucose.

The energy provided by glucose is used for the proper functioning of the brain. It generates ATP which is an energy source that is responsible for r neuronal and non-neuronal cellular maintenance and generates neurotransmitters.

Thus glucose-derived energy is critical for the health of the brain. Lack of energy can cause several brain diseases.
