Answer:
B. Dilation of vessels to the digestive organs.
Explanation:
The fight or flight response causes:
Inhibition of stomach and upper-intestinal action to the point where digestion slows down or stops.
Dilation of blood vessels for muscles.
Answer:
Taking into account that:
The flow velocity u of a fluid is a vector field
u = u (x, t)
What gives the velocity of a Fluid Plot at position x y time t.
q = || u ||
Now if the flow is continuous as it happens in the blood vessels then:
The flow of a fluid is said to be constant if it does not move over time, that is why the variant would be 0.
Explanation:
As for the pump with narrow vessels, there the area would be less, therefore the flow also and the flow velocity as well. Adding that the friction with the walls increases as it is narrower, thus generating an increase in pressure with the flow of the liquid.
So this is where we have to put emphasis on the biophysics branch that explains the following:
The Venturi effect is explained by the Bernoulli Principle and the principle of continuity of mass. If the flow rate of a fluid is constant but the section decreases, the speed necessarily increases after crossing this section. By the theorem of conservation of mechanical energy, if the kinetic energy increases, the energy determined by the value of pressure necessarily decreases.
Indeed, according to Bernoulli's principle:
P 1 + 21 ρv 12 + ρgh 1 = P 2 + 21 ρv 22 + ρgh 2

Facts about Flu
Flu is caused by influenza viruses.
Flu is a contagious respiratory infection.
Young children and older people have a higher risk of catching the flu.
Flu is transmitted through the air when an infected person sneezes or coughs.
Common symptoms of the flu include fever, chill, sore throat, coughing and sneezing, nausea and vomiting, headache and body ache, and fatigue.
There is no cure for the flu. However, it is advisable for people over six months of age to take a flu shot every year when it becomes available. Flu shots are a preventive measure for the flu. Besides the injection form, flu vaccines are also available as nasal sprays. When all children in a childcare setting have received the flu shot, it greatly reduces the risk of the infection spreading in the event that someone gets the flu.
Flu can cause complications in young children. Common complications include sinus infections, ear infections, and pneumonia. High fever or a combination of the infections mentioned here can be dangerous for young babies, who may require hospitalization. However, antiviral drugs are available to treat even babies.
