leonid [27]

Answer:

Tendon sheaths <u>act as friction-reducing structures.</u>

Explanation:

Tendon sheaths are fibrous tissue that is around tendons to protect and make the movements of these smoother. For example, they reduce the friction of the flexors and extensors tendons of the hand. These are tendons that we constantly use to open and close our hands when we want to grab objects. Without the sheath, the tendons will not move easily, and due to the excessive use, there can be inflammation.

The sheats have two layers, one internal, which is a synovial one that produces synovial fluid to lubricate the tendon, and the external, which is a fibrous layer.

What takes place when you inhale and exhale ?
vovangra [49]
When you inhale and exhale, you actually breathe. When you inhale, your intercostal muscles between ribs and diaphragm contract. This increases the space in chest cavity so your lungs can expand and the air enters the lungs. When you exhale, intercostal muscles and diaphragm relax reducing the space in the chest which leads to removing the air from the lungs.
