Blood pressure:

The force that blood exerts on the arterial walls.

Expressed as a fraction

systolic pressure/diastolic pressure

Aorta

largest artery in the body

Arteriole

Small artery

Artery

largest type of blood vessel

Atrioventricular bundle

Specialized muscle fibers connecting the atria with the ventricles and transmitting electrical impulses between them

Atrioventricular node (AV node)

Specialized tissue in the wall between the atria

Atrium

one of two upper chambers of the heart

Capillary

smallest blood vessel

Carbon dioxide

Gas released by body cells transported via veins to the heart, and then to the lungs for exhalation

Coronary arteries

Blood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle

Deoxygenated blood

blood that is oxygen-poor

Diastole

relaxation phase of the heartbeat

Electrocardiogram

record of the electricity flowing through the heart

Endocardium

inner lining of the heart

Endothelium

innermost lining of blood vessels

Mitral valve

Valve between the left atrium and the left ventricle

Murmur

Abnormal swishing sound caused by improper closure of the heart valves

Myocardium

muscular, middle layer of the heart

Normal sinus rhythm

heart rhythm originating In the sinoatrial node with a resting rate of 60-100 beats per minutes

Oxygen

Gas that enters the blood through the lungs and travels to the heart to be pumped via arterioles to all body cells

Pacemaker

Specialized nervous tissue in the right atrium that begins the heartbeat

Pericardium

Double-layered membrane surrounding the heart.

Pulmonary artery

Artery carrying oxygen-poor blood from the heart to the lungs

Pulmonary circulation

Flow of blood from the heart to the lung and back to the heart

Pulmonary Value

positioned between the right ventricle and the pulmonary artery

Pulmonary vein

one of two pairs of vessels carrying oxygenated blood from the lungs to the left atrium of the heart

Pulse

beat of the heart as felt through the walls of the arteries

Septum (Septa)

wall dividing a cavity

Sinoatrial node (SA node)

Pacemaker of the heart

Sphygmomanometer

instrument to measure blood pressure

Systemic circulation

Flow of blood from body tissue to the heart and then from the heart back to the body tissue

Systole

contraction phase of the heartbeat

Tricuspid valve

Located between the right atrium and the right ventricle

Valve

Structure in veins or in the heart that temporarily closed an opening so that blood flows in only one direction
