The Nervous System
Neurons
Send information around the body using electrical signals
Peripheral Nervous System
Part of the nervous system consisting of the nerves that connect the body to the nervous system
Central Nervous System
Part of the nervous system consisting of the brain and the spinal cord
Respiratory System
Lung
Holds oxygen to enter the bloodstream through diffusion
Bronchus
Deliver air into the lungs
Trachea
Separates into two different branches called bronchi
Pharynx
Tube that air flows down to reach the trachea
Mouth
Nasal Cavity
Allows air to enter the body
The Circulatory System
Blood Vessels
Capilleries
Thin-walled blood vessel that enable the exchange of gas, nutrients and waste
Veins
Blood vessel that returns blood to the heart
Arteries
Thick-walled blood vessel that carries blood away from the heart
Heart
Heart Attack
Coronary arteries become blocked, preventing flow of blood and oxygen
Contracts to pump blood throughout the body
Blood

Contain hemoglobin to transport oxygen throughout the body
Connective tissue that circulate throughout the body
Organs
Tissue
Nerve Tissue
Specialized tissue that conducts electrical signals from one part of the body to another
Muscle Tissue
Group of specialized tissues containing proteins that can contract and enable movement
Connective Tissue
Specialized tissue that provides support and protection
Epithelial Tissue
Tightly packed cells that cover body surfaces and internal organs
Support of the microscope
Moves stage in small increments
Moves the stage to general focus
Connects base to nosepiece and eyepiece
Magnfication
Ocular Lens Magnification x Objective Lens Magnification
Magnifies the image created by the objective lens
Provides light through the stage onto the slides
Controls the amount of light passing through the slide
Where the slides is placed
Hold the slides in place on the stage
Different lenses with different levels of magnification serve to magnify the object
Holds the objective lenses
Holds the ocular lens
Only able to differentiate into certain types of cells
Can differentiate into any kind of cell
An undifferentiated cell that can divide into specialized cells
Treatments
Biphotonics
Detects and treats cancer through use of beams of light
Radiation
Damages and prevents cell division using ionizing radiation

Mitosis
Telophase
New nuclear membrane forms around each group of daughter chromosomes
Anaphase
Centromere splits and sister chromatids separate to opposite sides of the cell, becoming daughter chromosomes

Tubes for transportation of materials throughout the cell
Contains enzymes that convert stored energy into usable energy
glucose + oxygen → carbon dioxide + water + usable energy
Nucleas
Contains genetic information to control cell activity
Permeable membrane layering the cell
Water material containing organelles
