Iteru [2.4K]

Answer:

Option c. cause pooling of the blood and decreased venous return to the heart

Explanation:

The ACE inhibitors increases the diameter of the blood vessels (vasodilation) that improves the flow of blood. This reduces the work load on the heart. At the time of heart failure, a substance called angiotensin is released. This angiotensin formation is blocked by the ACE inhibitors. Angiotensin is involved in narrowing the blood vessels.

The ACE cause pooling of the blood and decreased venous return to the heart. The ACE inhibitors causes vasodilation that allows decrease in blood pressure. So, there is no increase in arterial pressure, aldosterone and loss of volume. Thus, option C is correct.

Considering the example given the freshly cut grass, gentle breeze and sound of children laughing are the physical feelings stimulating your nose, skin, and ears.
  • <em>Selective attention</em> is focusing on a particular object in the environment for a certain period, in your example, the subject is not specifically focusing on one thing at the time.
  • <em>Sensory adaption</em> is the reduction in sensitivity to a stimulus after constant exposure to it, in this case, the subject is nos experiencing awareness of a constant stimulus.
  • <em>Cognition</em> is the process of acquiring knowledge and understanding through thought, experience, and the senses. In your example, the data obtained by the subject is still not processed.

I hope you find this information useful and interesting! Good luck!
