Basic Physiology

The basic physiology section contains information about the skeletal system, the muscular system and the cardiovascular system (respiratory system +  cardiovascular system).

The Skeletal System

The skeletal system consists of the bones and joints. The skeletal system has a number of key roles including: 1) Support - bones act as a supportive framework; 2) Protection of delicate organs (e.g. the brain, heart and lungs); 3) Movement - the bones act as anchor points for muscles allowing movement; 4) Storage - bones act as stores of some minerals and fats; 5) Blood cell production - red and white blood cells, along with platelets are produced within the bone marrow.

The Muscular System

The muscular system is made up of over 600 muscles which are responsible for every movement we make, including pumping blood around the body, moving food through the digestive system, opening and the enlargement and contraction of blood vessels in the skin. Muscles are powered by individual muscle cells which contract within a muscle.

The cardiovascular system can be divided into four main parts: 1) The respiratory system; 2) The Heart; 3) The Blood; and 4) The Blood vessels
