Answer:

Option (d).

Sophie [7]
Myocardial infarction, also known as heart attack to most people, is a result of an acute blockage of bloodflow to the heart. If a patient would ask the nurse why he/she is experiencing pain, it is best to tell the patient that chest pain or any discomfort in the arm, shoulder, neck, or back is caused by the decrease of blood flow to heart. Add to that, the nurse may inform the patient that people experiencing heart attacks may also feel shortness of breath, along with sweating, weakness, nausea, and fatigue. It is important to inform the patient about these symptoms so that he/she will be aware that these are common for people with myocardial infarction and that immediate medical attention is a must.

The circular folds of the small intestine enhance absorption by causing the chyme to spiral, rather than to move in a straight l
Pavlova-9 [17]

Answer:

The correct answer will be- true.

Explanation:

The small intestine is the longest part of the gastro-intestinal tract which helps in the absorption of nutrients from the digested food.

The structure of small intestine contains cell membrane extensions called villi and micro-villi which increases the surface area for absorption. The small intestine increases the food absorption by peristaltic movement of the food chyme. The small intestine causes the food chyme to form spirals which passes the food to large intestine.

Thus, true is the correct answer.
