Genesis 2:7
The heart, the blood vessels, and the blood they contain
Cardiovascular system
carries blood to heart
Veins
carries blood away from heart
Arteries
brings blood to cells for oxygen
Capillaritis
thick fluid containing many solid particles
Blood
most plentiful of the blood proteins,helps regulate the amount of water in the blood
Albumin
liquid or straw colored portion of blood
Plasma
disease-fighting proteins
Antibodies
disorder resulting from too little oxygen being transported to body cells
Anemia
a special iron-containing blood protein that binds easily to oxygen and gives blood its characteristic red color
Hemoglobin
blood cell that carries oxygen
Red blood cells
form of anemia caused by a genetic defect in the hemoglobin molecules that makes them clump together
sickle cell anemia
Where are red blood cells produced?
Where do they originate from?
Red bone marrow- produced stem cells-originate
True or False: red blood cells are replaced constantly
true
hand-sized organ that SUPPLIES THE BODY WITH STORED RED BLOOD CELLS whenever it needs extra oxygen-carriers
Spleen
White blood cells: function as part of the ____ system
immune
clot outside the body
Scab
a form of cancer in which white blood cells are produced in uncontrolled number
Leukemia
used to seal the break
Clotting
tiny disk-shaped cell fragments produced in the bone marrow to serve as patch kits/ patch leaks
Platelets
disease where your body can’t clot
Hemophilia
act as identification tags
Antigens
a transfer of someone else’s blood into your body
Blood transfusion
defense proteins in your bloodstream
Antibodies
ABO blood group
Universal recipients
Universal donors
Only A antigen: A blood
Only B antigen:B
Both B and A antigen: AB
Neither A nor B antigen: O
Rh blood group
Rh factor: antigen named after rhesus monkey
Rh positive: contains Rh factor
Rh negative: does not contain Rh factor
described the pathway of blood through the heart
WIlliam Harvey

heart
hollow spaces of heart
thin-walled upper chambers
thick-walled lower chambers
divides 2 sides of heart
Chambers
Atria
Ventricles
Septum
most important layer of the heart; contains the muscles of the heart
Myocardium
allows blood to flow from each atrium into the corresponding ventricle
A-V valve
allows blood to exit the right ventricle and enter the pulmonary artery
pulmonary valve
allows blood to exit the left ventricle and enter the aorta
Aortic semilunar
steps that heart travels
Venae cavae
Right atrium
Right ventricle
pulmonary artery
Lungs
Pulmonary veins
Left atrium
Left ventricle
Aorta
Rest of the body
supply heart with blood; branch from the base of the aorta
Coronary arteries
short, branched, and contain only one nucleus per cell
Cardiac muscle
system of special heart cells that regulates the beating of the heart
Cardiac conduction system
stimulate cardiac muscles to beat
Pacemaker
Pacemaker of heart
S-A
allows atrium to contract
A-V
detects the tiny electrical currents in the heart through electrodes taped to the patient’s chest, arms, and legs
Electrocardiogram
The contracting and pumping phase of heart action
the relaxing and filling phase of heart action
Systole
Diastole
how the cardiac cycle is perceived
Heartbeat
doctor for the diseases of heart
Cardiologist
when the heart stops beating and instead twitches randomly
Ventricular fibrillation
abnormal heart sound
Heart murmur
The movement of the blood through all parts of the body except the lungs
Systemic circulation
type of heart failure caused by a blockage of blood flow to the heart muscle
heart attack
form of arteriosclerosis in which a buildup of plaque and scar tissue narrow the inside of an artery
atherosclerosis
the flow of blood to the heart muscle through the coronary arteries and back to the right atrium
Coronary circulation
circulation that allows the blood to be filtered and processed so that proper body function can be maintained
Portal circulation
circulation that also allows the blood to be filtered and processed so that proper body function can be maintained
Renal circulation
movement of blood between the heart and the lung
Pulmonary circulation
The force that blood exerts upon the walls of the blood vessels
Blood pressure
the pressure during Systole
the pressure during diastole
Systolic pressure
Diastolic pressure
the scientific name for high blood pressure
Hypertension
rhythmic pressure change
Pulse
Form that glucose is stored as
Glycogen
the buildup of fatty deposits and fibrous tissue in the liver
Cirrhosis
liver infection that can be acquired by skin contact, contaminated food, blood transfusions, and intravenous drug use
Viral hepatitis
the leading cause of death among americans
Cardiovascular disease
excess weight puts a great stress on the heart
Obesity
body system that takes oxygen into the body and releases carbon dioxide from the body
Respiratory system
main organs of the respiratory system
Lungs
The process of breathing—inhaling and exhaling air
External respiration
The exchange of oxygen and carbon dioxide
between the blood cells and the tissue cells
Internal respiration
breakdown of glucose to produce energy
Cellular respiration
air enters through body through this
Nose
warms, moistens, and filters air as it passes through nose
Nasal cavity
scientific name for voice box
Larynx
folds of elastic tissue; produce sound for speech
Vocal cords
branches into which a bronchus divides after entering the lungs
Secondary bronchi
The secondary bronchi branch many times to form still smaller tubes called _____
Bronchioles
the thin-walled air sacs at the ends of the smallest bronchial tubes in the lungs
Alveoli
the inflammation of the lining of bronchial tubes
Bronchitis
a bacterial or viral infection of the linings in the lungs that causes the lungs to secrete large quantities of fluid
Pneumonia
protects your lungs
Rib cage
double membrane that provides lubrication between the ribs and the surface of the lungs. inflammation of this?
pleura. Pleurisy
thick sheet of muscle that separates the thoracic cavity from the abdominal cavity
diaphragm
process in breathing in which air rushes INTO the lungs because of decreased pressure
inhalation
process in breathing in which air rushes FROM the lungs because of increased pressure
exhalation
monitors amount of oxygen in blood
Medulla oblongata
