Cardiorespiratory endurance
The ability of the heart, lungs, and blood vessels to distribute nutrients and oxygen to and remove wastes from the body's tissues during extended periods of vigorous activity
Cardiology
The study of the heart and the body's network of blood vessels and their functions
Cardiovascular system
The heart, arteries, veins, capillaries, and the blood
Arteries
Carry blood away from the heart
Veins
Return blood to the heart
Capillaries
Connect the arteries and the veins and provide for the exchange of nutrients and waste materials in every cell of the body
Atria
Two thin-walled upper chambers; atrium
Ventricles
Two thick-walled lower chambers
Septum
Thick vertical wall that divides the left chambers from the right chambers
A-V Valve
Separate each atrium and ventricle
Pulmonary arteries
Travels to the lungs, where an exchange of gases takes as the blood receives oxygen and gives up carbon dioxide
Pulmonary veins
Four veins two on each lung that oxygenated bloods flows through
Pulmonary circulation
The flow of blood from the heart to the lungs and back to the heart
Aorta
The body’s largest artery
Arterioles
Smaller arteries
Venules
Smaller ventricles
Venae cavae
The body’s largest veins
Systemic circulation
The movement of blood through all parts of the body except the lungs
Blood pressure
The amount of force that blood exerts upon the walls of the blood vessels
Systolic pressure
The pressure during the contraction of the ventricles
Diastolic pressure
The pressure during relaxation of the ventricles
Pulse
The rhythmic change of pressure that causes the arteries’ walls to bulge outward and then return to normal
Radial arteries
Wrists
Cardiod arteries
Neck
Stroke volume
The volume of blood ejected from the ventricles with each contraction and your stamina
Pneumology
The study of the respiratory system its structure, functions, disorders, and diseases
Lungs
Large, spongy, organs located inside the thoracic cavity on either side of the heart
Pharynx
Throat
Glottis
The opening of the trachea
Larynx
Voice box
Trachea
Windpipe
Epiglottis
The flap of cartilage covering the glottis
Bronchi
Two folds of elastic tissues
Bronchi
Bronchus
Bronchioles
The smallest bronchial tubes
Alveoli
Microscopic air sacs that make up the tissue of lungs
Diaphragm
Airtight chamber with a moveable floor of muscle
Vital capaciy
The volume of air when you inhale and exhale as much air as you can
