What happens to the food we eat? The role of the digestive system is to convert the complex food we eat into simple forms that can be absorbed into our bodies and used for energy, growth, repair and the manufacture of essential chemicals. It does this by physically breaking food into smaller pieces, and also … Read moreAnatomy and Physiology: How Digestion Works
You body gets its energy and nutrients through eating, but the food that you eat is very different to what’s used by your cells. Ingested food must go through the process of digestion. There are two stages of digestion: mechanical, which starts in the mouth with chewing and swallowing; and chemical, which involves enzymes breaking … Read moreAnatomy and Physiology: Aromatherapy and the Digestive System
Anatomy of the Neck and Shoulders The neck is one of the most flexible parts of the spine, able to bend to the front and side, and, to a lesser extent, backwards, and allowing a large degree of rotation. Many muscles are needed to engineer all these movements. They range from large sheets of muscles, … Read moreAnatomy and Physiology: How the Neck and Shoulders work
Anatomy of the Face and Head The head, particularly the face, is probably the single body region that most determines how we respond to the world around us, and because of our society’s emphasis on looks, the way in which others respond to us. The face and head contain the sense organs, the structures which … Read moreAnatomy and Physiology: How the Head and Face Work
Why We Need Skin What we can see and touch of our skin is just the surface of a complex structure that carries out many functions. For instance, our skin acts as the first line of defence against harmful micro-organisms. It plays an important part in helping maintain body temperature and in balancing out levels … Read moreAnatomy and Physiology: How the Skin Works
Reproductive System Structure and Function Reproductive system The reproductive system controls the ability to reproduce which is necessary for perpetuation of the species. Although the reproductive apparatus of males and females are different, the organs of both sexes may be divided into two groups: primary and accessory. Primary organs: Gonads Male – testes Female – … Read moreAnatomy and Physiology: The Reproductive System
Lymphatic System Structure and Function Lymphatic system The lymphatic system drains away excess fluid that does not return to the blood capillaries; absorbs fats from the small intestine and protects against foreign invaders. Structure of the lymphatic system: Capillaries – function – allows for easy passage of soluble materials and water Lymphatic vessels – function … Read moreAnatomy and Physiology: The Lymphatic System
Urinary System Structure and Function Urinary system The urinary system removes waste products from the blood and eliminates them from the body. Other functions include regulation of the volume of body fluids and balance of the pH and electrolyte composition of these fluids. Structure of the urinary system: Kidneys – function – extract waste from … Read moreAnatomy and Physiology: The Urinary System
Digestive System Structure and Function Digestive system The digestive system serves to supply constant nutrients which provide energy and building blocks to every body cell. This is achieved by the breaking down of food into small enough particles to pass through the cell membrane, known as digestion; and transference of these small particles to the … Read moreAnatomy and Physiology: The Digestive System
Nervous System Structure and Function Nervous system The nervous system serves as the chief coordinating agency. Conditions within and outside the body are constantly changing; the nervous system responds to these changes causing the body to adapt itself to new conditions so that balance is maintained. Organisation of the nervous system: Structural divisions: Central Nervous … Read moreAnatomy and Physiology: The Nervous System
