Answer:
The correct option is (D). The value of cardiac output in the case of the human heart is approx. 5 liters in a minute. The multiplication product of heart rate and stroke volume gives the cardiac output.
Explanation:
The blood flow serves as the parameter for the calculation of cardiac output. For the restoration of homeostasis, increase or decrease in the cardiac output leads to the simultaneous increase and decrease in the blood flow and pressure respectively. Also, the reduction of cardiac output and venous return signifies the higher value of the tidal volume. The associated parameters namely stroke volume and heart rate is also affected by certain factors. Some of them includes age, gender, contractility, heart size and duration of contraction.
Besides the flow of blood in the body depends on the oxygen requirement of the target cell.
Hello!
While they do not penetrate very far into the body, they can indeed get through.
Commonly, materials that emit alpha, beta or gamma radiation get into the body alone or with other materials which have may become contaminated.
Here are some ways these could get in:
Through breathing; It could be in the air or mixed with dust, which is in the air.
Drinking; It disolves in water, meaning the material could get in your body without you knowing.
In the soil; If soil is contaminated, and plants grow in that soil, you will get a small ammount of alpha and beta particles.
Lastly, animals; Plants and animals can become contaminated, the particles coud be taken in through consumtion.
Hope this helps!
Have a great day!
