Within this report I will be describing what the cardiovascular system is, how it works, and what it consists of. I will also be talking about the respiration system, what it is, how it works and what it consists of.
P1 – Describe the Structure and function of the Skeletal System
At birth, a new born infant has around 300 bones, whereas the average adult has only 206 bones (this can change depending on each individual). The difference comes from the small bones that fuse together during the growth period; an example of this would be the sacrum and coccyx of the vertebral column. The sacrum consists of five bones which are separate during the early stage of a child’s development, but these will fuse together into a solid structure in the later years. An infant will be born with zones of cartilage, these are called epiphyseal plates, and they are segments of bone that allow further growth. Growing is usually completed between ages 15 – 19, at which time the epiphyseal plates of long bones close off, allowing no further growth.
All these bones are then separated into five different groups, long, short, flat, irregular and sesamoid.
The long bones are found in the arms and the leg. They are longer than they are wide, and they are hollow with bone marrow inside of them.
The short bones are found in the ankles, feet, wrists, and the fingers. They are cube shaped, very light and strong.
The flat bones are strong, flat plated, and provide protection for all the major organs, such as the brain, heart and the lungs. They can also provide attachment for muscles.
Irregular bones are bones that don’t fit into any category, they help to support and protect joints, and an example of this would be the vertebrae.
And finally, the sesamoid bones, they are usually short or irregular bones that are placed / imbedded within a tendon. An example of this
