Retina
The retina is the part of the eye which converts light into electrical impulses with its photoreceptor cells (rods and cones) to the brain. Vision is achieved when light enters the pupil, focused by the lens, and converted into signals in the retina.
Answer: The talk test is used to measure moderate-intensity activities. If a person can talk during an activity, but cannot sing, they are engaged in moderate-intensity activity. If they cannot talk, they are doing a higher-level intensity activity.

Explanation:
Empathy means experiencing someone else's feelings It requires an emotional component of really feeling what the other person is feeling. Sympathy, on the other hand, means understanding someone else's suffering.
The following activities and body conditions affect blood pressure by changing one of the two listed factors. They are classified as follows:
Blood Volume:
- Smoking (Increase)
- High altitude living (Decrease)
- Increased sympathetic activity (Increase)
- Growth (Increase)
- Excessive Sweating (Increase)
- Blood Donation (Decrease between 0-48 Hours)
Total Peripheral Resistance:
- Smoking (Increase)
- Increased sympathetic activity (Increase)
- Blood Donation (Increase)
<h3>
What is Total Peripheral Resistance?</h3>
Vascular resistance is the resistance that needs to be overcome in order for blood to move through the circulatory system.
The overall resistance to blood flow through peripheral vascular beds influences cardiac output significantly. An increase in total peripheral resistance elevates arterial blood pressure, which reduces cardiac output.
Because cardiac output increases more than total resistance reduces during exercise, mean arterial pressure normally rises only little. The increase in tidal volume and the speed at which the stroke volume is expelled, on the other hand, causes a significant increase in pulse pressure.
