The largest artery in the body, the aorta carries oxygenated blood from the left ventricle of the heart to the rest of the body.
Aorta
An upper chamber of the heart where blood enters. The heart has two; the left (connects to the lungs) and the right (connects to the veins)
Atrium
A type of vessel that carries blood from the heart through the body; part of the circulatory system.
Artery
A problem with the rate/rhythm of your heartbeat
Arrhythmia
Where the lungs and blood exchange oxygen and carbon dioxide when breathing in/out
Alveoli
The pressure that blood exerts upon the walls of blood vessels, especially arteries, usually measured with a sphygmomanometer
Blood Pressure
A slower than usual heart beat
Bradycardia
The large air passages that lead from the trachea to the lungs.
Bronchi
Supply blood to the heart. Made up of the 2 right and the 2 left.
coronary arteries
Any of the branches in which the bronchus divides
bronchioles
One of the 2 branches of the main coronary artery. It delivers oxygenated blood to the left atrium.
Circumflex Artery
2 arteries, 1 found on each side of the head in which they deliver blood to the head and brain.
Carotid Artery
The transport system of the body responsible for carrying oxygen and nutrients to the body and carrying away carbon dioxide
Cardiovascular System
A measure of how much blood is pumped by both ventricles in one minute.
Cardiac Output
The stage in a heartbeat when the heart is relaxed and the heart chambers fill with blood
Diastole
A muscle that separates the thorax from the abdomen. It plays a major role in breathing and helps inflate the lungs.
Diaphragm
A measurement of heart electrical activity.
Electrocardiogram (EKG)
An irregular heartbeat that occurs when the electrical signals in the atria fire rapidly at the same time
Fibrillation
A measure of cardiac activity usually expressed in number of beats per minute
Heart Rate
Rapid or deep breathing. It is a response to stress on the body usually caused by anxiety or panic.
Hyperventilation
The “good” cholesterol that helps remove the less beneficial forms of cholesterol from blood.
High Density Lipoprotein (HDL)
A major vein that collects blood from the skull, brain, neck, and face.
Jugular Vein
Supplies blood to the LEFT side of the heart
Left Coronary Artery
The largest coronary artery that supplies the left ventricle with oxygenated blood.
Left Anterior Descending Artery (LAD)
The area of the throat containing the vocal cords and used for breathing, swallowing, and talking
Larynx
The “bad” cholesterol that can build up in the arteries and help form plaques
Low Density lipoprotein (LDL)
Part of the respiratory tract. Divided into 2 passages that moisten, warm, and filter air before it enters the lungs.
Nasal Cavity
The rhythmic expansion and recoil of arteries resulting from heart contraction
Pulse
A passageway for air to enter the larynx and lungs, as well as food and water to enter the esophagus.
Pharynx
Supplies blood to the right ventricle and atrium of the heart.
Right Coronary Arteries.
The process of inhaling oxygen and exhaling carbon dioxide
Respiration
The stage in a heartbeat when contraction of the heart pushes blood out of the chambers and into the aorta and pulmonary artery.
Systole
An instrument used to measure blood pressure
Sphygmomanometer
the volume of blood pumped out of the heart’s left ventricle during each systolic cardiac contraction
Stroke Volume
A test that measures how well your lungs are working by measuring how much air you can inhale and exhale.
Spirometry
A medical term for a heart rate of over 100 beats per minute
Tachycardia
The airway that leads from the larynx to the bronchi.
trachea
A blood test to measure all types of cholesterol in your blood
Total Cholesterol
Lipids that circulate the blood. It is the most common type of fat found in foods.
Triglycerides.
A lower chamber of the heart where blood exits. There are 2
Ventricle
2 large veins, one located on the bottom of the heart that delivers blood to the lower half of the body whereas the second vein is located superior to the heart and delivers blood to the neck and head.
Vena Cava
A vessel that delivers deoxygenated blood to the heart.
Vein
A body structure that temporarily closes a passage and it permits movement of fluid in one direction.
Valve
