Vocabulary List
Cells - the functional basic unit of all living organisms, often referred to as the building block of life
Tissues - a group of cells from the same origin which together, carry out a specific function
Organs - a collection of tissues joined in a unit which carry out the same function
Organ Systems - an ensemble of organs working together to perform a certain task eg. Circulatory System
Respiratory - an organ system which takes in oxygen & removes carbon dioxide & water, the system used for breathing
Respiratory Organs include the trachea, bronchioles, lungs, mouth
Circulatory - the organ system which pumps blood from the heart to the lungs and the rest of the body through the arteries and veins
Circulatory Organs include the heart and blood vessels
Endocrine - the system which generates hormones that control bodily functions
Endocrine Organs include the pituitary gland, adrenal glands, thymus gland, thyroid gland, ovary, testes
Digestive - the organ system which breaksdown foodstuffs & absorbs them into the circulatory system
Digestive Organs include the liver, gall bladder, pancreas, salivary gland, esophagus, stomach and intestines
Lymphatic - the system that contains nodes that may inflame and indicate the presence of infection and drains fluid from around cells to eliminate swelling
Lymphatic Organs include nodes, tonsils, spleen
Muscular - the organ system that maintains the body's heat & posture and moves bones & protects organs
Nervous - the system which coordinates body actions & monitors the environment
Nervous Organs include the brain, nerves
Integumentary - the system which is the first line of defense against infection and maintains body temperature
Integumentary body parts include the skin, hair & nails
Reproductive - the organ system which produces offspring to maintain the species
Reproductive Organs include the uterus, fallopian tubes, testes, ovaries and vas deferens
Urinary - the system which removes liquid waste from the body
Urinary body parts include the ureters, urethra, bladder
Skeletal - the organ system which provides support & protection
Skeletal Organs include the cartilage, bones, joints

Every part of a living organism works together in order for an organism to function. Cells working together form tissues. Tissues working together form organs. Organs working together form organ systems and organ systems working together make an organism function. Different organ systems in the human body are the; respiratory system, circulatory system, endocrine system, digestive system, lymphatic system, skeleto-muscular system, nervous system, reproductive system, integumentary system and urinary and excretory system. Each organ system carries out a specific function and all the organs in the organ system do something different so that when they are working together they perform a certain life task.

8/8/11 - Digestive System- Vocabulary List

anus - the opening at the end of the digestive system from which faeces exit the body.
appendix - a small sac located near the start of the large intestine.
oesophagus - the long tube between the mouth and the stomach. It uses rhythmic muscle movements (called peristalsis) to force food from the throat into the stomach.
gall bladder - a small, sac-like organ located by the duodenum. It stores and releases bile (a digestive chemical which is produced in the liver) into the small intestine.
large intestine - the long, wide tube that food goes through after it goes through the small intestine. It contains a good bacteria which removes nutrients and water from waste.
liver - a large organ located above and in front of the stomach. It filters toxins from the blood, and makes bile (which breaks down fats) and some blood proteins. It also stores nutrients.
mouth - the first part of the digestive system, where food enters the body. Chewing and salivary enzymes in the mouth are the beginning of the digestive process (breaking down the food).
pancreas - an enzyme-producing gland located below the stomach and above the intestines. Enzymes from the pancreas help in the digestion of carbohydrates, fats and proteins in the small intestine. It makes chemicals need to break down food and it also makes insulin.
rectum - the lower part of the large intestine, where faeces are stored before they are excreted from the body.
small intestine - the long, thin winding tube that food goes through after it leaves the stomach. Nutrients are absorbed into the blood stream here.
stomach - a sack-like, muscular organ that is attached to the oesophagus. When food enters the stomach, it is churned in an acid bath. It contains digestive juices to break down food.
teeth – chop and grind
tongue – mixes the food with the saliva
duodenum – first part of the small intestine where food is broken down further by digestive juices and enzymes
salivary glands – make saliva
enzyme – chemical that breaks down food
gland – a factory
insulin – helps cells use sugar
digestive juices – acids and enzymes in the stomach that break down food
bile – yellow-green fluid that breaks down fat

9/8/11 Nutrients for the Body- Carbohydrates, Proteins and Fats and Oils

Food Group
Potatoes, Bread, Pasta
The starch in carbohydrates turns sugars into glucose, which in turn provides energy for the body
Nuts, Meat, Fish
Proteins help your body grow and replace worn out tissue
Fats and Oils
Butter, Milk, Cheese
A requirement for a healthy body, it keeps you alive and forms a layer of insulation. It also is an important component of your cell membrane

15/8/11 Skeletal System- Three Main Functions

- To protect the vital organs of the body that keep us alive
- Help us to move and give our body shape, also being an attachment for muscles to hang on to
- Produce bone marrow which produces red and white blood cells
