Coal miners inhale large quantities of fine coal dust when they are working in the mines. Over the years, the dust irritates their alveolar surfaces resulting in inflammation and then development of scar tissue (a tough, stiff, thick, fibrous tissue) within the lung walls. Answer the following questions based on a coal miner who has developed very extensive and severe scar tissue in their lungs. 1. Define compliance. 2. Would coal miners have high or low lung compliance? Explain. 3. What happens to the skeletal muscle force required to generate a normal TV? 4. Given your answer to #3, with this very severe situation, can skeletal muscle continue indefinitely to generate the required force? Why or why not? And if not, then what change in TV occurs? 5. Explain what happens to alveolar ventilation. 6. What happens to arterial blood Po2 levels? Explain, and be sure to include which variable(s) of Fick's law are altered.
Musculoskeletal System
The musculoskeletal system, also called the locomotor system, is an organ system that gives humans and animals the ability to move using their muscular and skeletal systems. It provides stability, form, support, and movement to the body. The skeleton is composed of bones (skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system is subdivided into two broad systems, such as the muscular system and the skeletal system.
Skeletal structure
The skeletal system is the core framework of the human body. The skeletal structure comprises bones and connective tissue, including cartilage, ligaments, and tendons. The skeletal structure of our body acts as a support structure. It maintains the body's shape and is responsible for its movement, blood cell formation, protection of organs, and mineral storage. The skeletal system is referred to as the musculoskeletal system.

Over the years, the dust irritates their alveolar surfaces resulting in inflammation and
then development of scar tissue (a tough, stiff, thick, fibrous tissue) within the lung
walls.
Answer the following questions based on a coal miner who has developed very
extensive and severe scar tissue in their lungs.
1. Define compliance.
2. Would coal miners have high or low lung compliance? Explain.
3. What happens to the skeletal muscle force required to generate a normal TV?
4. Given your answer to #3, with this very severe situation, can skeletal muscle
continue indefinitely to generate the required force? Why or why not? And if not,
then what change in TV occurs?
5. Explain what happens to alveolar ventilation.
6. What happens to arterial blood Po2 levels? Explain, and be sure to include which
variable(s) of Fick's law are altered.
7. What happens to arterial blood hemoglobin saturation (% HbO2)? Explain.
8. What happens to arterial blood Pco2 levels. Explain, and be sure to include which
variable(s) of Fick's law are altered.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5fecec17-55f3-4204-b7e7-5a9e74d3fa68%2F63dacefe-b438-44f6-915f-1fa3b362a9c6%2Fhzng62_processed.png&w=3840&q=75)
