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

He was known for the "Allotey Formalism" which arose from his work on soft X-ray spectroscopy. He was the 1973 recipient of the UK Prince Philip Golden Award for his work in this area.

Answer:
If red blood cells are placed in a hypertonic solution, they will shrink because the water moves out of the cell through osmosis. When red blood cells are places in hypotonic solution they swell and rupture because the water moved in the cell through osmosis.
Explanation:
If red blood cells are placed in 1400mOsm of NaCl, the cell volume will be lost because the wayer in the cell moves out due to higher concentration of salt outside, they will shrink.
Similarly if the red blood cells are places in urea and NaCl the cell will again shrink.
Interviews revealed that nurses played the following roles when caring for women who have experienced IPV: identifying abuse, taking care of patients' physical health needs, attending to their safety, making referrals, and providing support and advice.
<h3>What is physical health?</h3>
Physical fitness refers to a state of health and wellbeing and, more particularly, the capacity to engage in certain activities related to sports, jobs, and daily living. Physical fitness is often attained with healthy eating, moderate-intense exercise, enough rest, and a formal recovery plan.
Fitness was once understood to be the ability to complete the day's tasks without becoming overly exhausted or lethargic. The ability of the body to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, to improve the immune system, and to respond to emergency situations is now considered to be measured by physical fitness due to automation and changes in lifestyle.
