Name the body structure concerned with the given functional activity : Prevents food from entering the trachea during swallowing.

The human ciculatory system can be thought of as a closed system of interconnecting pipes through which fluid is continuously circulated by two pumps the two pumps the right and left verticles of the heart, work as simple two-stroke force pumps. The muscles of the heart regulate the force by contracting and relaxing. the contraction (systole) lasts about 0.2s and a complete systole/diastole (contraction/relaxation) cycle lasts about 0.8s. For flood pressures and speeds in the normal range. the volume flow rate of blood through a blood vessel is directly proportional tot he pressure difference over a length of the vessel and to the fourth power of the radius of the vessel. The total mechanical energy per unit volume of blood just as it leaves the heart is E//V=rhogh+P+rhov^(2) Q. Why is diastolic blood pressure muchh lower than systolic pressure? A. because the heart exerts more force on the blood during diastole B. Because the heart exerts no force on the blood during diastole C. Because the radii of the blood vessels increase during diastole while the force exerted by the heart on the blood remains the same. D. Because the radii of the blood vessels increase during diastole while the force exerted by the heart on the blood remains the same.

Assertion :- Larynx is a cartilaginous box which helps in sound production. Reason :- Epiglottis flap covers the glottis during swallowing and prevents the entry of food into the larynx.
