Cells & Systems
This is the basic unit of life.
Cells
This principle states that pressure is transmitted equally in all directions in a confined fluid.
What is Pascal’s Principle
Light travels in this type of path
Straight Lines
The main organ of the circulatory system
The Heart
This part of the eye controls how much light enters
The Pupil
This organ system transports oxygen and nutrients throughout the body.
the circulatory system?
The resistance of a fluid to flow
viscosity
A surface that reflects light and forms images
mirrors
This system protects the body from disease and infection
The Immune System
The colored part of your eye that controls the size of the pupil
The Iris
These cell structures control what enters and exits the cell.
cell membrane?
The mass of fluid per unit volume.
Density
The bending of light as it passes from one material to another.
Refraction
This organ filters toxins from the blood
The Liver
The part of the eye where images are formed and light is detected
The Retina
The jelly-like substance inside the cell.
cytoplasm
A liquid is more viscous when this happens to its temperature
The temperature decreases
A transparent object that bends light to form images
Lens
The system that produces hormones to regulate body functions
The Endocrine System
These cells in the retina allow you to see color.
Cones
These cells do not have a nucleus.
prokaryotic cells
This principle explains how airplanes achieve lift
Bernoulli’s Principle
These surfaces scatter light in many directions
Rough Surfaces
The large, coiled part of the digestive system that absorbs water
The Large Intestine
The condition where the eye focuses light in front of the retina, causing blurry distance vision
myopia
