Cards

Term
Teeth
Definition
Physical Digestion: Incisors specialize in cutting, Canines specialize in tearing, premolars specialize for grinding, and molars are designed for crushing
Term
Tongue
Definition
Important in chewing and swallowing.
Term
Salivary Glands
Definition
Physical Digestion: Saliva lubricates food to facilitate swallowing.
Chemical Digestion: Saliva contains Amylase enzymes, which break down starches.
Term
Stomach
Definition
Physical Digestion: Responsible for churning.
Chemical Digestion: Kills pathogens with stomach acids (HCl and Pepsin)
Term
Liver
Definition
Produces bile salts and manufactures blood protein.
Removes toxic nitrogen
Stores glycogen to glucose
Detoxifies harmful compounds, such as alcohol, to less harmful products.
Term
Gall Bladder
Definition
Stores and concentrates bile which emulsifies fat.
Term
Pancreas
Definition
Secretes digestive enzymes into duodenum.
Term
Small Intestine
Definition
Stores Amino Acids, Glucose/Fructose, and Fatty Acids/Glycerole
Peristalsis moves food through.
Term
Large Intestine
Definition
Stores H2O
Empties contents into rectum
Term
Septum
Definition
Divides two pumps of the heart
Term
Atria
Definition
Receive blood returning to the heart
Term
Ventricles
Definition
Pump blood out of the heart
Term
Atrioventricular valves
Definition
Prevent blood from flowing backwards through the heart
Term
Semilunar Valves
Definition
Prevent blood in arteries from flowing back into the ventricles
Term
Coronary arteries
Definition
Branch off of the aorta to bring oxygen and nutrients to the heart
Term
Arteries
Definition
Carry blood away from the heart; always open. High pressure
Term
Veins
Definition
Carry blood to the heart; contain valves to prevent blood from flowing backwards. Low pressure.
Term
Capillaries
Definition
A single layer of cells that are the sites of fluid and gas exchange between blood and body cells.
Term
Plasma
Definition
Component of blood that contains albumin (maintains osmotic pressure and blood), serum globulins (act as antibodies to prevent disease) and fibrinogens (required for blood clotting).
Term
Erythrocytes
Definition
Hemoglobin in these red blood cells carry oxygen. They contain carbonic anhydrase to facilitate the formation of carbonic acid from carbon dioxide and water.
Term
Leukocytes
Definition
These white blood cells divide into granulocytes (contain cytoplasmic granules) and Agranulocytes.
Term
Platelets
Definition
Component of blood produced in the bone marrow that is required for blood clotting.
Term
Red bone marrow
Definition
Produces all blood cells
Term
Spleen
Definition
Blood reservoir, releases red blood cells when necessary
Term
Thymus Gland
Definition
Located behind sternum, front of chest cavity up to throat site of Thylumphocytes maturation
Term
Lymph
Definition
A clear fluid which passes slowly but freely between the spaces between all cells and tissues.
Term
Lymph nodes
Definition
Glands which filter out and digest bacteria and other foreign materials picked up by the lymph
Term
Trachea
Definition
This windpipe is lined with mucus-producing cells, which trap debris that may have escaped the filters in the nasal passage.
Term
Cilia
Definition
Tiny hairlike protein structures found on some cells that sweep foreign debris from the respiratory tract.
Term
Epiglottis
Definition
A structure that covers the glottis (opening of the trachea) during swallowing
Term
Alveoli
Definition
Sacs of the lung in which the exchange of gases between the atmosphere and the blood occurs
Term
pleural membrane
Definition
A thin, fluid-filled membrane that surrounds the outer surface of the lungs and lines the inner wall of the chest cavity.
Term
Diaphragm
Definition
Sheet of muscle that separates the organs of the chest cavity from those of the abdominal cavity.
