mouth and stomach

mechanical and chemical digestion (2 answers)

duodenum

chemical digestion only

liver

produces bile

stomach

produces pepsin

duodenum

final digestion

jejunum

absorption of nutrients

colon or large intestine

absortion of water and storage of bile

gallbladder

stores bile

amylase

enzyme that digests starch in the mouth

lipase

enzyme that digests fats/lipids

pepsin

enzyme that digests protein in the stomach

hydrochloric acid

kills the bacteria in the stomach

objective lense

Primary lenses for magnification (4x, 10x, 40x, 100x).

nosepiece

Holds and rotates objective lenses.

coarse adjustment knob

this part moves the stage up and down to help you get the specimen into view

fine focus knob

Used for detailed focusing, especially at higher magnifications.

stage

Where the specimen slide is placed.

stage clips

Hold the slide in place.

diaphragm

Controls the amount of light reaching the specimen.

body tube

houses the eyepiece

base

supports the whole microscope

arm

where we hold the microscope

eyepiece

used to view or see the specimen

light source

supplies light into the state of microscope

transmission electron microscope

used to examine closely the internal structures of microorganisms

convex lens

what kind of lens is used in a compound microscope?

nonliving

what kind of specimen are used when we view the image using an electron microscope?

coronary artery

Supplies blood to the heart itself.

red bone marrow

is responsible for producing blood cells

blood

is the fluid that fills the circulatory system

Light microscope

The lenses bend, or refract the light,which makes the object beneath them appear closer. Magnifies objects up to 2000 times. Two dimensional images. Bonuses: Relatively inexpensive,

can view living organisms .

electron microscope

use electrons

(negatively charged electrical

particles) to view the specimen.

Scanning Electron Microscope (SEM)

It allows scientists to view objects in

3D SEMs magnify objects up to

50,000X, non-living specimens.

Transmission Electron Microscope (TEM)

The electrons are passed through very thin

specimens; magnify objects up to 250,000X. Two dimensional images, non-living specimens.

stereo microscope

is often used for lower- power magnification on large subjects.

head, base, and arm

The three basic, structural components of a compound microscope are the

head/body

houses the optical parts in the upper part of the microscope

base

of the microscope supports the microscope and houses the illuminator

arm

connects to the base and supports the microscope head. It is also used to carry the microscope.

eyepiece

The part you look at with your eye. Usually 10 X magnification.

eyepiece tube

holds the eyepieces in place above the objective lens.

objective lenses

are the primary optical lenses on a microscope. They range from 4x-100x and

typically, include, three, four or five on lens on most microscopes.

revolving nosepiece

houses the objectives. The objectives are exposed and are mounted on a rotating turret so that different objectives can be conveniently selected.

coarse adjustment knob

Used to make large changes in focus.

fine adjustment knob

Used to small adjustments of focus

coaxial focus knobs

hey are built on the same axis with the fine focus knob on the outside, and are more convenient since the viewer does not have to grope for a different knob.

stage

is where the specimen to be viewed is placed.

mechanical stage

is used when working at higher magnifications where delicate movements of the specimen slide are required.

stage clips

are used when there is no mechanical stage. The viewer is required to move the slide manually to view different sections of the specimen.

aperture

is the hole in the stage through which the base (transmitted) light reaches the stage.

illuminator

is the light source for a microscope, typically located in the base of the microscope. Most

light microscopes use low voltage, halogen bulbs with continuous variable lighting control located

within the base.

condenser

is used to collect and focus the light from the illuminator on to the specimen. It is located

under the stage often in conjunction with an iris diaphragm.

iris diapragm

controls the amount of light reaching the specimen. It is located above the condenser

and below the stage.

light source

Sends light up through the

diaphragm and through the

slide for viewing

diaphragm

Use to vary the

amount of light passing through

the slide. Usually it is better if

the amount of light is low.

body tube

Reflects light up to the viewer's eye

atrium/atria

What is the upper receiving

chamber of the heart called?

ventricles

What is the lower pumping

chamber of the heart called?

septum

What muscle separates the right and left sides of the heart?

deoxygenated blood (DOB)

What kind of blood flows in the right side of the heart?

oxygenated

What kind of blood flows in

the left side of the heart?

deoxygenated blood

What kind of blood flows in

the pulmonary artery?

oxygenated blood

What kind of blood flows in

the pulmonary vein?

vena cava

What is the largest vein?

aorta

What is the largest artery?

tricuspid valve

the valve found between the right atrium and right ventricle.

bicuspid valve

the valve found between the left atrium and leftventricle.

artery

Which blood vessel carries blood

away from the heart?

vein

Which blood vessel carries blood back to the heart?

capillary

Which blood vessel connects the arteries and veins?

vein

Which blood vessel contains valve?

capillary

What is the smallest blood vessel that brings oxygen

and nutrients to cells in your organs?

red blood cells

Which blood cells distribute oxygen

throughout the body?

white blood cells

Which blood cells protect the body from diseases?

blood platelets

Which blood cells are responsible in blood clotting?

red bone marrow

Where are blood cells produced?

right atrium

What chamber of the

heart receives

deoxygenated blood

from the different

parts of the body?

left atrium

What chamber of the

heart receives

oxygenated blood

from the lungs?

right ventricle

What chamber of the

heart pumps

deoxygenated blood

to the lungs?

left ventricle

What chamber of the

heart pumps

oxygenated blood to

the different parts of

the body?
