Location(s): Skin, Lining of digestive system, certain glands Function: Protection, Absorption, and excretion of materials
Location : Under Skin, surrounding organs, blood, bones Function: Binding of epithelial tissue to structures, support and transport of substances
Location: Brain, Spinal Cord, and Nerves Function: Receiving and transmitting nerve impulses
location: Skeletal muscles, muscles surrounding digestive tract and blood vessels, the heart function: Voluntary and involuntary movements
The process in which a stimulus produces a response that opposes the original stimulus
Function :Ingestion= Intake Digestion: breaking down of polymer to monomers
getting ride of undigestible
monomers being _____ in to the blood stream in the small intestines
function: eliminates wastes products from the body (blood stream/ fluids)
Organs of importance in Excretory System
Skin, Lungs, Liver, Kidneys
Filtration in excretory
Blood-->nephron Location: B. Capsule
Resorption in Excretory
nephron--> blood Location : Loop of Henle, CD
the Flow of Urine
Kidneys --> Ureters--> Bladder --> Urethra
Filter wastes and help maintain homeostasis by regulating the amounts of water, salt , and the other substances dissolved in body fluid.
The process of putting food into your moth- opening of digestive tract. Location: Opening of digestive tract
The physical breakdown of large pieces of food into smaller pieces
Enzymes break down food into small molecules location: small intestines
The process in which cells in the small intestines intake the small food molecules
Contractions of smooth muscles that move food through the esophagus to the stomach
Salivary amylase break down starches into disaccharides
Transports food from mouth to stomach
prevents a back flow of materials back into the esophagus. The cardiac sphincter closes to allow the food to stay within the stomach so it can be digested. Cardiac sphincter, working with the pyloric sphincter keeps the stomach content from moving elsewhere.
Pepsin, breaks down proteins into large particles- pepsin Ph 2
controls movement of acid in stomach
6 meters in length, 2.5 cm thick Function: Nutrients are absorbed after being broken down. Enzymes: Pancreatic Amylase (trypsin, lipase, multose, sucrose, lactase)
shorter than small intestines, the thick, lower end of the digestive system, containing the appendix, colon and rectum. Its principle function is to reabsorb water and maintains the fluid balance of the body. Certain vitamins are also taken in through its wall.
Round, Muscular- Function- Releases wastes
Any of the organs that secrete saliva. Three pairs of major glands secrete saliva into the mouth through distinct ducts: the parotid glands (the largest), between the ear and the back of the lower jaw; the submaxillary glands, along the side of the lower jaw; and the sublingual glands, in the floor of the mouth near the chin. There are also numerous small glands in the tongue, palate, lips, and cheeks. The presence, smell, or thought of food normally increases secretion.
Location: above intestines- made up of blood vessels - converts glycogen back into glucose, manufactures proteins. Takes glucose out of blood stream and makes it glycogen. Controls glucose levels and creates bile
Releases digestive enzymes, glycogen
Antidiuretic Hormone (ADH)
Regulates water balance, produced in the brain and is stored and released in the pituitary gland.
monitor the concentration of water and dissolved substances in the blood.
______ increase the permeability of the walls of the nephron to the water. This increases the amount of water being reabsorbed back into the blood stream.
Finger like projections
transport urine from the kidneys to the urinary bladder
storage area of urine
a million individual processing units
passing a liquid or gas through a filter to remove wastes
filtration of blood mainly takes place here
a small but dense network of capillaries (very small blood vessels) encased in the upper end of each nephron by a hallow cup- like structure
the process by which water and dissolved substances are taken back into the blood
loop of henle
a responsible for conserving water and minimizing the volume of the filtrate
