B would be the correct answer
Answer:
When the body is stressed, muscles tense up. Muscle tension is almost a reflex reaction to stress—the body’s way of guarding against injury and pain.
With sudden onset stress, the muscles tense up all at once, and then release their tension when the stress passes. Chronic stress causes the muscles in the body to be in a more or less constant state of guardedness. When muscles are taut and tense for long periods of time, this may trigger other reactions of the body and even promote stress-related disorders.
Explanation:
For example, both tension-type headache and migraine headache are associated with chronic muscle tension in the area of the shoulders, neck and head. Musculoskeletal pain in the low back and upper extremities has also been linked to stress, especially job stress.

Explanation:
Answer:
- human respiratory system
- x= rings of cartilage y= alveolar sac z= lungs
- this diagram is important for a human being because
- respiration is a complex process during which digested food is oxidized to release chemical energy it involves a series of reaction all of them catalyzed by specific enzyme
- the energy is stored in ATP molecules
4. ring of cartilage help to ensure that the air passage does not collapse
each bronchiole terminates into a sac called Alveolar sac it is surrounded by an network of blood capillaries exchange of gases takes place in a the alveoli oxygen from the inhaled air diffuse into the blood while CO2 from the blood diffuse into the alveoli
lungs : a pair of of lungs are present in the thoracic activity lungs are spongy,elastic bags consisting of bronchi ,bronchioles,alveoli
