The blood receiving chambers
of the heart are the atria.
The pumping chambers of the heart
are the ventricles.
Blood returns to the heart from
the lungs by means of the
pulmonary veins.
The large artery carrying blood
away from the left ventricle of
the heart is the aorta.
Blood vessels that carry blood
away from the heart are
arteries.
Blood vessels that carry
blood toward the heart are
veins.
On the right side of the heart,
the valve between the right
atrium and right ventricle is the
Right AV valve (or tricuspid
valve).
The flaps of the heart valves
are anchored to the wall of the
ventricles by tissue chords
known as Chordae Tendinae.
Arteries that supply blood to the
tissue of the heart itself are the
coronary arteries.
What part of the intrinsic conduction system
sets and controls your heart rate?
The SA node
Heart contraction is also
known by the term
Systole.
Heart muscle relaxation is
also known by the term
Diastole.
A normal heart rate is
approximately
60-90 beats per minute.
Unusual heart sounds, such
as those emitted by poorly
functioning valves, are called
Heart murmurs.
The smallest vessels in the
body. They carry blood to the
cells of body and allow
materials to be exchanged
between blood and cells.
Capillaries
Structures in veins that
prevent blood from flowing
backwards.
Valves
A typical blood pressure reading
contains two numbers of which the
first number is the systolic pressure
and the second number is the
diastolic pressue.
The only major artery in the
body that carries blood low in
oxygen is the
pulmonary artery.
The only veins of the body that
carry blood high in oxygen are the
pulmonary veins.
The fluid portion of
the blood is the
plasma.
The major molecule that
transports oxygen within red
blood cells is hemoglobin.
Red blood cells survive and
circulate in the human blood
stream for approximately
100-120 days.
The production of red blood
cells is stimulated by a
hormone known as
Erythropoietin or EPO.
Antibodies are produced
by white blood cells known
as B cells.
Platelets play a major role in
what process?
Blood clotting.
The two major types of cells in your
lymph nodes are T-lymphocytes (T
cells) and B-lymphocytes (B cells).
Substances capable of stimulating
the immune system are known as
antigens.
Foreign organisms are
engulfed by macrophages in
a process known as
phagocytosis.
The cells needed to activate both Bcells and Killer T-cells are called
Helper T-cells.
The nerve that carries impulses
from the eye to the brain is the
optic nerve.
The retina is composed of what
two types of cells that are
sensitive to light?
Rods and Cones
The outer wall of the eye
consists of the cornea and the
sclera.
The jellylike substance that fills
the posterior chamber of the
eye is called vitreous humor.
The pupil of the eye is an opening
in the colored portion of the eye
known as
the iris.
The eyelids are covered on
their inner surfaces by the
mucous membrane called the
conjunctiva.
Tears that bathe the eyeball and
keep it moist and clean are
produced by
lacrimal glands.
Color vision and detailed
vision are made possible by
retinal cells known as
cones.
Place in the retina where
most cones are concentrated
and detailed vision is the
best is the
fovea.
The optic disc contains no visual
receptors and is therefore called
the blind spot.
The lobe of the brain where
visual information is interpreted
is the occipital lobe.
The change of the lens shape to
focus objects at various distances
is under the control of a muscle
called the ciliary muscle.
The middle ear bones, which
transmit sound to the inner
ear, are known as the ossicles.
The long, slender tube leading
from the pharynx (throat) to the
middle ear is the Eustachian tube.
The snail-like structure of the
inner ear used for hearing
sounds is called the
cochlea.
The five primary tastes are
sweet, sour, salty, umami, and
bitter.
Name the air sacs in your lungs
where gas exchange takes place.
Alveoli
Name the flap of cartilage that
prevents food and drink from
entering your larynx.
Epiglottis
Anatomical term for the throat.
Both air and food pass through it.
Pharynx
Main tube that conducts air to your lungs.
It is held open by rings of cartilage.
Trachea
Structure that is right above the trachea.
It is where the vocal cords are located.
It enlarges during in males during puberty.
Larynx
These glands are important for moistening
food and producing enzymes that help start
carbohydrate digestion and help kill bacteria.
Salivary Glands
Muscular tube that conducts food from
the pharynx (throat) to the stomach.
Esophagus
This organ produces bile.
The liver
This organ stores bile. And then contracts to secrete bile
into the small intestine after meals.
Gall bladder
Bile helps to digest this type of food.
Fats and oils
This organ is located right below and behind
the stomach. It’s digestive function is to produce
a number of enzymes for digestion. It secretes
those enzymes into the small intestine.
Pancreas
Produces very acidic gastric juice and
enzymes to digest food.
Also uses strong muscular contractions
to mix and break down food.
Stomach
