Epithelial Tissue

Location(s): Skin, Lining of digestive system, certain glands Function: Protection, Absorption, and excretion of materials

Connective Tissue

Location : Under Skin, surrounding organs, blood, bones Function: Binding of epithelial tissue to structures, support and transport of substances

Nervous Tissue

Location: Brain, Spinal Cord, and Nerves Function: Receiving and transmitting nerve impulses

Muscle Tissue

location: Skeletal muscles, muscles surrounding digestive tract and blood vessels, the heart function: Voluntary and involuntary movements


Stable environment

Feedback Inhibition

The process in which a stimulus produces a response that opposes the original stimulus

Digestive System

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

Excretory System

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

Urine Excretion

CD--> Ureter

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

Physical Digestion

The physical breakdown of large pieces of food into smaller pieces

Chemical Digestion

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

Cardiac Sphincter

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

Pyloric Sphincter

controls movement of acid in stomach

Small intestines

6 meters in length, 2.5 cm thick Function: Nutrients are absorbed after being broken down. Enzymes: Pancreatic Amylase (trypsin, lipase, multose, sucrose, lactase)

Large intestines

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.

Anal Sphincter

Round, Muscular- Function- Releases wastes

Salivary Glands

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

Gall Bladder

Stores Bile


Releases digestive enzymes, glycogen

Antidiuretic Hormone (ADH)

Regulates water balance, produced in the brain and is stored and released in the pituitary gland.

Osmoreceptor cells

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

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

Bowman's capsule

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
