Cells are the smallest living part of a plant or animal. All living things are composed of one or more cells.
What is cell specialization?
Cell specialization is when a certain type of cell preforms a certain function within an organism/organ.
What is cell Division?

Digestive Term: Mouth
-Mechanical digestion (breaks down food to be swallowed)
-Chemical digestion (silvia helps break down food to be swallowed)
Digegestive Term: Oesophagus
-Moves food to the stomach by peristalsis
-Has a mucous lining
Digestive Term: Liver
-Stores vitamins and minerals
-Breaks down poisons
-COnverts glucose to glycogen
Digestive Term: Pancreas
-produces pancreatic juices
-continues digestion of carbohydrates
Digestive Term: Gall Bladder
Digestive Term: Small Intestines
-where nutrients are absorbed into blood stream by villi
-has a bumpy surface called villi
-has a mucus lining
Digestive Term: Large Intestines
-water is absorbed
-stool form here
-has five main parts (anus, rectum, colon, cecum and appendex)
Respiratory Term: Lung
The organ for breathing air
Respiratory Term: Trachea
narrow tube called windpipe
Respiratory Term: Bronchi
two narrow tubes of trachea leading into lungs
smaller tubes coming off the bronchi in the lung
Respiratory Term: Alveoli
Thousands of tiny air sacs after bronchioles that are connect to cappilaries
Respiratory Term: Capillaries
Conect to Alveoli and pass oxygen into the blood stream and C20 (carbon dixoide) back to the lungs
Respiratory Term: Diaphragm
Breathing in the diaphragm tightens allowing lungs to expand
Breathing out the diaphragm relaxes releasing air, making lungs smaller
Circulatory Term: Heart
The organ which pumps oxygenated blood around the body and then oxygenates deoxygenated blood.
Circulatory Term: 4 chambres
left and right atria, left and right ventricles
Circulatory Term: valves
4 sets of valves, their job is to stop blood from flowing backwards.
Circulatory Term: Aorta
Takes oxygenated blood around to the body
Circulatory Term: Vena Cava
Returns deoxygenated blood back to the heart
Circulatory Term: Pulmonary Arteries
Takes blood from right ventricle to the lung to be oxygenated
Circulatory Term: Pulmonary Veins
Takes blood from the left ventricle to the heart oxygenated
Blood Vessels: Artery
-pumps blood away from heart
-thick elastic wlss
-blood is pumped under high pressure
Blood Vessels: Vein
-Thin elastic walls
-returns blood to the heart
-low blood pressure
Blood Vessels: Capillary
-One cell thick
-They provide oxygen and food to every cell in the body
-They remove carbon dioxide from every cell
Plasama is what of blood
Water, protein, C20, waste materials, nutrients and other substances
White blood cells
Are the 'soldiers' of the body
less than 0.01% of blood
function:aids in clotting the blood (when you cut youself, etc)
Each drop of blood contains
300million red blood cells
Red blood cells
red blood cells travel around your body up to 300,000 times or about 120days
1.7thousands red blood cells are reproduced each minute.
Excretory Term: Kidney
The role of the kidney is to remove nitrogenous wastes from the body. Nitrogenous means that it is a rich element nitrogen.
Excretory Term: Liver
Has small organelle which is peroxisome, responsible for converting toxic substances into nontoxic substances.
Excretory Term: Ureter/Renal Pelvsis
Pumps urine from the kidney to the bladder,This takes the urine away from the ureter and stores it in the bladder
Excretory Term: Urine
A fluid stored in the bladder and removed through the uretha
Excretory Term Bladder
Store urine, collects from ureter then removes it by the uretha
Excretory Term: Renal Artery
Takes oxygenated blood to the kidney from the the Aorta.
Excretory Term: Renal Vein
Takes deoxygenated blood back to the Vena Cave which takes it to the heart to be oxygenated
Excretory Term: Uretha
Takes urine from the the bladder to the outside of the body
Is made up of one cell
example: Bacteria and Protist
Vacuole (plant cell)
Large sac filled with cell sap, when full helps cell stay firm
when haemoglobin is carrying oxygen around the body
the pigment that makes red blood cells red
Controls everything inside cell and inheritance information.
secretes a waste called sweat (secretion release through oozing a substance through glands or a cell)
The process of which a unicellular divides into two then four and so on and so forth.
Is when some has lack of red blood cells
Thousands or millions of molecules make up organelles. Each organelle is different and had a particular job to do.
Examples: cell wall, chloroplast, cell membrane
Made up of one or more different of tissue and carry out one (or sometimes more) main function or job.
Examples: Brain, Lung, etc
