Skeletal System
_
The Skeletal System is responsible for several things in the
human body. It gives structure to the body, it acts like scaffolding to hold
organs, and it has bone marrow which makes blood cells. The skeletal structure
is made up of fused and individual bones that are supported by ligaments, tendons,
muscles, and cartilage. There are approximately 6 major functions of the skeletal
system. Here they are.
Support-
The skeleton gives structure and shape to the body. It is the foundation that the rest our our body is built around. It also keeps things in place, without the ribs the lungs and heart would collapse.
Movement-
The joints in our skeleton allow us to move. There are pivoting joints and gliding joints. The bones give the muscles and place to attach to. The muscles then use the joints like a lever with the joint being the Fulcrum. without bones muscles wouldn't have anything to pull or move.
Protection-
Our skeleton also protects our Vital Organs. the skull protects the eyes the ears and the brain.
the ribs protects the lungs heart and the major blood vessiles. the spine protects the spinal cord.
Blood cell Production-
the Marrow in the bones is responsible for making new blood cells through a process called Haematopoiesis. During this process the body can make up to 500billion new cells a day. Bone marrow is also important in the Lymphatic System.
Storage-
Bones can store Calcium. Along with Calcium bone marrow can store Iron and Ferritin.
Endocrine Regulation-
Bone cells release a hormone called Osteocalcin. It contributes to the regulation of blood sugar and fat deposition. Osteocalcin also helps control insulin secretion and sensitivity, along with controlling the number of insulin producing cells

Food
Food effects the skeletal system in a few ways. it first gives the bones energy to make blood cells. it also gives them support and strength. the food gives the bones Calcium and other minerals to remain healthy.
_Key Words-Fulcrum- the pivot point on a lever
Vital Organs- organs that are needed to live Lymphatic System- the system that controls fluids in the body Haematopoiesis- the process of making blood cells Calcium- a mineral found in bones and teeth Iron- a mineral found in the blood system Ferritin- a mineral Osteocalcin- a hormone the controls the regulation of sugars in the body. |
