6 things transported by cardiovascular system
Oxygen, Carbon dioxide, Nutrients, Hormones, Waste Products, Enzymes
chambers of the heart receive blood from veins
chambers of the heart are known as pumping chambers?
pressure during heart muscle contraction
pressure during relaxation of heart muscle
rhythmic vibration felt in an artery as a result of the beating of the heart.
fluid portion of blood
the red blood cells used to carry oxygen and carbon dioxide
the white blood cells used to fight infection
platelets used to clot blood
blood vessels that provide oxygen and nutrients to the heart
Superior vena cava drains heart from head, neck, and arms. Inferior vena cava drains blood through the abdomen, and legs into right atrium. Coronary sinus drains blood from myocardium into the right atrium.
Right atrium to right ventricle through tricuspid valve. Deoxygenated blood
right ventricle through pulmonary valve to pulmonary artery. Deoxygenated blood.
Pulmonary artery branches into left and right pulmonary arteries into lungs for deoxygenated blood exchange and oxygenation.
oxygenated blood returns from lungs through left and right pulmonary veins into left atrium
left atrium through bicuspid (mitral) valve into left ventricle
left ventricle through aortic valve into aorta
aorta, oxygenated blood flows into arteries, arterioles, capillaries, venules, and
veins, returning to the superior and inferior vena cava
used to denote the aortic valve, prevents back-flow of blood from the aorta into the left ventricle.
vessel that carries blood away from the heart. carry oxygenated blood the exception is the pulmonary artery, which carries deoxygenated blood to the lungs.
chamber of the heart that collects blood returning from the rest of the body. The right atrium collects deoxygenated blood from the body and passes it to the right ventricle. The left atrium collects oxygenated blood from the lungs and passes it to the left ventricle.
Relating to the heart, or to one of the two arteries that originate in the aorta and supply blood directly to heart tissue.
Valve that separates the left atrium and the left ventricle and prevents back-flow (Atrium to ventricle)
relating to lungs
separates the right atrium and the right ventricle and prevents back-flow from the ventricle to the atrium.
A vessel that carries blood toward the heart.
chamber of the heart that is responsible for pumping blood out to the rest of the
body. left and right. The right ventricle pumps
deoxygenated blood to the lungs via the pulmonary artery; the left ventricle pumps oxygenated blood to the body via the aorta.
Excessively rapid heartbeat.
Period of contraction of the heart during which blood is ejected from the ventricles.
A brief loss of consciousness caused by temporary lack of oxygenated blood.
Localized loss of blood supply due to a mechanical obstruction.
A condition in which a person's blood pressure is abnormally high. For normal
adults, the pressure should be less than 130 mmHg systolic and less than 85 mmHg diastolic.
Pressures above 140/90 indicate a mild form of hypertension; above 180/110 is considered
This is the general term for diseases of the heart muscle. The most common
of these diseases is the dilated cardiomyopathy in which the disease weakens the heart muscle
and causes left ventricular dilation leading to increased diastolic pressure and volume.
Difficulty in breathing.
Normal period of relaxation and dilatation of the heart cavities.
A condition in which a person's skin is discolored to a bluish hue because of
inadequate oxygenation of the blood.
Excessively slow heartbeat.
act of listening, with a stethoscope, to sounds made by the heart, lungs, and blood.
An accumulation of fat-containing deposits on arterial walls.
irregular heart beat
Chest pain caused by insufficient blood flow to the heart muscle.
A pathological blood-filled dilatation of a blood vessel.
A deficiency in the oxygen-carrying material of the blood.
