How do systolic and diastolic blood pressure values relate to the action of the heart and movement of blood in arteries? quizley

Answer:

ventricles contract and movement of blood is towards the body in systolic blood pressure and ventricles relax and movement of blood is towards heart in distolic blood pressure.

Explanation:

Blood pressure is the pressure exerted by blood on the walls of blood vessels. The standard blood pressure in human adults is 120/80.

During Systolic blood pressure, the heart <em>ventricles contract</em> and pump the blood to arteries, arterioles, capilaries then venules and veins from an area of higher pressure to lower pressure. Simply, the heart pumps the oxygenated blood towards the body. It is the higher value (120).

The Diastolic blood pressure is lower arterial pressure (80) and produced during <em>ventricular relaxation</em>. During diastolic blood pressure, the heart refills it and thus deoxygenated blood move towards heart from body.

Hoping this might be helpful...!

How long does it take for a person's cells to all die after clinical death?
Blababa [14]
Clinical death is the medical term for cessation of blood circulation and breathing, the two necessary criteria to sustain human and many other organisms' lives.

It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest.


Brain injuries start to accumulate almost immediately after Clinical Death.

Full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare.

Usually brain damage or later brain death results after longer intervals of clinical death even if the heart is restarted and blood circulation is successfully restored.
Although loss of function is almost immediate, there is no specific duration of clinical death at which the non-functioning brain clearly dies.






The most vulnerable cells in the brain, CA1 neurons of the hippocampus, are fatally injured by as little as 10 minutes without oxygen.

However, the injured cells do not actually die until hours after resuscitation.

Brain failure after clinical death is now known to be due to a complex series of processes called Reperfusion Iinjury that occur after blood circulation has been restored, especially processes that interfere with blood circulation during the recovery period.

Hope this helps!!!

Which type of population growth is shown in this graph? Population of Bacteria
Lesechka [4]

Answer:

Bacterial population shown in the graph is of Exponential type.

Explanation:

When the rate of population increases over time in proportion to the population size,  it is known as exponential growth of population. Bacterial reproduction happens in an hour time span for many bacterial species by splitting itself in half.

This shows how the exponential growth occurs in bacteria. The amount of population gets increased with added organisms in generations of species.
