Btec Sport Level 3 Unit 1 Bones

What are the functions of the skeletal system?

• The functions of the skeletal system include producing sound for speech

• The functions of the skeletal system include regulating body temperature

• The functions of the skeletal system include providing support for the body, protecting internal organs, producing blood cells, and enabling movement.

• The functions of the skeletal system include digesting food

Explain the structure of long bones.

• The shaft of long bones is filled with air instead of bone marrow

• Long bones are made entirely of cartilage

• Long bones have no specific structure, they are just solid bones

• Long bones have a shaft (diaphysis) and two ends (epiphyses) that are covered with articular cartilage. The shaft is hollow and filled with bone marrow. The outer layer of the bone is made of compact bone, while the inner layer is made of spongy bone. The bone is surrounded by a tough membrane called the periosteum.

How does exercise affect bones?

• Exercise helps to strengthen bones by increasing bone density and reducing the risk of osteoporosis.

• Exercise causes bones to become more brittle

• Exercise weakens bones by depleting bone density

• Exercise has no effect on bones

What are the primary functions of the skeletal system?

• Production of hormones

• Digestion of food

• Regulation of body temperature

• Las funciones principales del sistema esquelético son el soporte estructural del cuerpo, protección de órganos internos, movimiento y almacenamiento de minerales y producción de células sanguíneas.

Describe the composition of long bones.

• Long bones are composed of muscle and tendons

• Long bones are composed of a shaft (diaphysis) and two ends (epiphyses), which are covered with articular cartilage and filled with bone marrow.

• Long bones are composed of a single solid structure

• Long bones are composed of only cartilage

Discuss the impact of exercise on bone density.

• Watching TV can help increase bone density

• Exercise, especially weight-bearing and resistance exercises, can help increase bone density and reduce the risk of osteoporosis.

• Eating junk food can reduce the risk of osteoporosis

• Sleeping all day can have a positive impact on bone density

Why is the skeletal system important for athletes?

• Strong bones are a hindrance to athletic performance

• The skeletal system provides structure, support, and protection for the body, as well as producing red blood cells and storing minerals. This is crucial for athletes to maintain strong bones and overall physical performance.

• The skeletal system has no impact on athletic performance

• Athletes don't need strong bones to perform well

Explain the role of bones in movement and support.

• Bones are made of cartilage and do not contribute to movement or support

• Bones are only for protection, not for movement or support

• Bones are primarily responsible for producing blood cells, not for movement or support

• Bones provide support and structure to the body, and they also work with muscles to facilitate movement.

How does weight-bearing exercise benefit bone health?

• Weight-bearing exercise weakens bones and increases the risk of osteoporosis

• Weight-bearing exercise only benefits muscle strength, not bone health

• Weight-bearing exercise helps to strengthen bones and reduce the risk of osteoporosis by putting stress on the bones, which stimulates the formation of new bone tissue.

• Weight-bearing exercise has no impact on bone health

What are the different types of bone tissue and their functions?

• Los diferentes tipos de tejido óseo son el tejido óseo duro y el tejido óseo blando. El tejido óseo duro ayuda en la producción de células sanguíneas, mientras que el tejido óseo blando proporciona estructura y soporte.

• Los diferentes tipos de tejido óseo son el tejido óseo denso y el tejido óseo ligero. El tejido óseo denso proporciona flexibilidad, mientras que el tejido óseo ligero ayuda en la producción de células sanguíneas.

• Los diferentes tipos de tejido óseo son el tejido óseo compacto y el tejido óseo esponjoso. El tejido óseo compacto proporciona estructura y soporte, mientras que el tejido óseo esponjoso ayuda en la producción de células sanguíneas y proporciona flexibilidad.

• Los diferentes tipos de tejido óseo son el tejido óseo liso y el tejido óseo rugoso. El tejido óseo liso proporciona flexibilidad, mientras que el tejido óseo rugoso ayuda en la absorción de nutrientes.
