What causes the respiratory center in the medulla oblongata of the brain to increase the rate of respirations?
Answer:
decreased amount of oxygen or increased amounts of carbon dioxide in the blood
Explanation:
The medulla oblongata and the pons are involved in the regulation of the ventilatory pattern of respiration.
The decrease in blood pH result from the decreased amount of oxygen, Hypoxemia refers to insufficient oxygen in the blood. Thus any cause that influences the rate or volume of air entering the lungs (ventilation) or any cause that influences the transfer of air from the lungs to the blood may cause hypoxemia.
In response to a decrease in blood pH, the respiratory center (in the medulla ) sends nervous impulses to the external intercostal muscles and the diaphragm, to increase the breathing rate and the volume of the lungs during inhalation.
Also, Let take a look at a situation of an individual suffering from an anxiety attack(i.e hyperventilating). The increased ventilation rate will remove too much carbon dioxide from their body, (this implies that there is increased amounts of carbon dioxide in the blood). Without that carbon dioxide, there will be less carbonic acid in blood, so the concentration of hydrogen ions decreases and the pH of the blood rises.
In response, the respiratory chemoreceptors detect this change, and send a signal to the medulla, which signals the respiratory muscles to decrease the ventilation rate so carbon dioxide levels and pH can return to normal levels.
Answer:
What happens is the dehydration phenomenon.
Explanation:
The phenomenon of dehydration occurs because when you are at sea for many days, you breathe the salty mist that occurs on the surface of the sea (which is even greater at night), this mist is high in solutes and salts that is why that when inhaled, the body will seek to increase blood volume to lower the plasma concentrations of these solutes in the blood.
Also, during breathing, a lot of water is lost and other physiological processes are why we need a daily consumption of water.
In the case of this situation where the person is abandoned, water consumption is low.
The consequences of dehydration are serious, since there is hypotension, decreased blood volume, hypovolemic shock, loss of consciousness and even possible death.
No, I believe he would need multiple traits to see there was a law of segregation
The answer is caffeine. Caffeine
is used as a stimulant to maintain alertness and reduce drowsiness. Caffeine
is used to improve performance and most take it to allow them to continue
working when they naturally feel tired or
to stimulate the brain in the morning. It is consumed
in beverages such as tea, coffee, and soft drinks.
