·What are the two types of skeleton?
Axial skeleton: protects organs (skull, vertebrates, ribs)
Appendicular skeleton: allows movement (shoulders, armsm, legs)
·Type of joints
1.Joints can be classified by structure and function
2.The classification regarding texture is fibrous, cartilaginous and synovial
3.The classification regarding movement is movable, slightly movable and immovable
·Disorder of the skeletal system greenstick: incomplete break of the bone
Spiral: causey excessive twisting
Comminuted: bone is crushed into pieces
Transverse: fracture in straight line
Compound: expose of the bone through skin
·Type of muscles
Smoot: muscle contracts slowly. It if found in blood vessels and intestine. The control is involuntary
Skeletal: muscle contracts rapidly. It is found in the trunk, limbs, head and neck. Thecontrolis voluntary
Cardiac: musclecontracts rapidly. It is found in the heart. The control is involuntary
·Muscular system
1.Tendinitis inflammation of tendon that connect muscles to bones.
2.Rapidly hereditary disease in which the muscle becomes weaker over time.
3.Involuntary cause by overstretching the muscle.
·What is found in blood?
It is a fluid that carries gases, nutrients, and wastes through the body.
·Functions of the skeletal system
Function description
Protection It provide protection to organs such as brain.
Storage It stores important minerals such as calcium
Blood cells production Red marrow is in charge of producing red & white cells
Support Without bones and muscles we couldn’t move.
Movement It makes it possible for us to sit and stand.
·Label parts of the skeletal system
Bones they have blood vessels and nerves
Ligaments they hold bones together
Cartilage they allow movement without rubbing of bones
Minerals they make bones strong and hard. Calcium is the most plentiful
Connective tissue they made o collagen and withstand hits or bumps
Marrow there are two types found in the center of bones
·Venn diagram
Cardiovascular: blood flows in a close continuous loop throughout the body via the arteries, capillaries, and veins
Both: carry fluids through the body
Lymphatic: lymph is responsible for collect and removing waste products left behind in the tissues.
·What is the job of the lymph capillaries
They absorb fluids around the body
·Definitions:
Bone marrow is where blood cells are produced.
Thymus is where bone marrow finishes developing.
Lymph nodes are small organs that remove pathogens and dead cells
Tonsils defend the body against infections
Spleen stores white blood cells and allow them to mature
·Circulatory system definition
Heart: it contracts to pump blood to the body
Blood: they carry chemical messages and remove waste
Arteries: the carry oxygen-rich blood away
Veins: they carry oxygen-poor blood back to the heart
Capillaries: they deliver oxygen-rich blood and take oxygen-poor blood away
Which four type of cells is blood made of?
The type of cell are plasma, platelets, white blood cells and red blood cells
