Unit 5 – Anatomy and Physiology – Assignment 3 In this assignment I will outline the anatomy and physiology of these three body systems; The Cardiovascular system‚ The Respiratory system and The Digestive system. The Cardiovascular System The cardiovascular system‚ also known as the circulatory system‚ consists of the heart‚ blood vessels and approximately 5 litres of blood. 55% of the blood is straw coloured yellow and 45% of the blood is made up of red and white blood cells and tiny particles

Fibre can’t be digested‚ but keeps you filled up and water keeps up your liquid levels. What Happens in Each Organ During the Process of the Digestive System? The Mouth: This is where the digestion of food starts‚ even before you take a bite of a Cheese Sandwich‚ the smell of it triggers the salivary glands in your mouth to create saliva‚ making your mouth water; when the food is in your mouth‚ the saliva increases. The food is broken down into small pieces by chewing‚ which are then small enough

Ad1 Digestion is the mechanical and chemical breaking down of food into smaller components‚ to a form that can be absorbed‚ for instance‚ into a blood stream. Digestion is a form of catabolism; a break down of macro food molecules to smaller ones. The digestive process also involves creating waste to be eliminated. The digestive track (gut) is a long twisting tube that starts in the mouth and ends at anus. It’s made up of a series of muscles that coordinate the movement of food and other cells that

tongue‚ salivary glands‚ liver‚ gallbladder‚ and pancreas. To achieve the goal of providing energy and nutrients to the body‚ six major functions take place in the digestive system; Ingestion‚ secretion‚ mixing and movement‚ digestion‚ absorption‚ and excretion. The mouth is where food begins its journey through the digestive system in the mouth‚ also known as the oral cavity. Inside the mouth are many accessory organs that aid in the digestion of food‚ the tongue‚ teeth‚ and salivary glands. Teeth

Enzymatic reaction is known as digestion and this is defined as the chemical breakdown of the ingested complex food molecules by the action of biological enzymes‚ into simplest form that can be absorbed into the blood stream and assimilated into living cells. In human beings‚ various components of the ingested food are digested and absorbed at various sections of the alimentary canal . The first digestion process starts at the mouth in which cooked starch is reduced into simpler sugars by
