I'll try to explain, because I've had tubes before. In fact, I still have them.
For me, tubes were put in because of too many ear infections, and excessive water in my ear. The tube helped drain the water out. You can see A picture I have in a file. The tubes can be put I believe in the ear drum. They're put there to help drain water that has trouble getting out on its own.

Anxious and apprehensive are signs that the patient doesn't have enough blood to his brain. The cause probably is the low blood pressure. <span>
Open abdominal surgery is a major surgery so it should have a high risk of bleeding. </span>Bleeding in abdominal space is dangerous because it was not visible and space is massive. The source could be a rupture of a blood vessel or broken stitch of the surgical wound.

Answer:
The correct answer will be option-D.
Explanation:
Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.
Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.
This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.
Thus, option-D is the correct answer.
