Answers

Answer 1

Answer:

Smooth muscle (so-named because the cells do not have striations) is present in the walls of hollow organs like the urinary bladder, uterus, stomach, intestines, and in the walls of passageways, such as the arteries and veins of the circulatory system, and the tracts of the respiratory, urinary, and reproductive systems. Smooth muscle is also present in the eyes, where it functions to change the size of the iris and alter the shape of the lens; and in the skin where it causes hair to stand erect in response to cold temperature or fear.

What is fitness?

Fitness is defined as the ability to carry out daily tasks with optimal performance, endurance, and strength while managing disease, fatigue, and stress and engaging in less sedentary behavior.

Fitness entails some type of activity that enhances various systems of the body and retains a certain state within the body.

Health, on the other hand, involves every system within the body and can only be achieved through a healthy lifestyle.

The sit and reach test is a common flexibility test that assesses the flexibility of the lower back and hamstring muscles.

This test is important because lumbar lordosis, forward pelvic tilt, and lower back pain are all associated with tightness in this area.

Thus, the correct option is B.
