|
Epithelial Tissue |
-Line cavities and surfaces of blood vessels and organs throughout the body. - Are found in layers |
|
|
Connective Tissue |
-Supports organs -scattered throughout the extracellular matrix |
|
|
Types of Connective Tissue |
-Loose connective tissue (Connects epithelial tissue to underlying tissue) -Fibrous Tissue (Tendons) -Cartilage -Adipose Tissue -Bone -Blood |
|
|
Muscle Tissue |
- Abundant -Composed of muscle fibers and made of protein -Types: Skeletal (Helps with movement) Cardiac (only in heart tissue) Smooth Muscle (Found in many organs and can contract slowly for long time) |
|
|
Nervous Tissue |
-relays info from one part of body to the other - basic unit: neuron |
|
|
Open System |
system that exchanges chemicals and energy with its surroundings or environment |
|
|
Interstitial Fluid |
-fluid filling the spaces between cells where the exchange of nutrients and waste takes place |
|
|
Homeostasis |
-maintaining relatively constant conditions -Large external changes lead to small internal changes |
|
|
Negative and Positive Feedback Loops |
Negative Feedback: internal controller that helps keep the body from reaching certain extremes Positive Feedback: Results of a process spur the same process again and again (intensification) |
|
|
Thermoregulation |
-homeostatic measure containing temperature -ex: Fever |
|
|
Osmoregulation |
Control of the gain and loss of water High concentration of water molecules move to a lower one |
|
|
Urinary System Parts |
-Kidney (blood is filtered) -Ureter (tube leading to bladder) -Urinary Bladder (stores urine) -Urethra (A tube that empties near genitals) |
|
|
Urinary System Process |
-Like Airport Security -Filtration: water and other small molecules are forced out of blood and into tubule -Reabsorption: reclaims water and valuable solutes nutrients and returns them to blood - Secretion: Certain substances are taken from blood and put into the filtrate -excretion: you can guess |
