Across Flashcards
One of the layers found in arteries which allows them to construct or dilate
Smooth muscle
Larger blood vessels which carry blood back to heart
Veins
Main part of heart (mostly muscle)
Myocardium
The chamber of the heart which receives blood from rest of body
Right atrium
Smaller vessels that carry blood away from the heart
Arterioles
Receives blood returning from the lungs
Left atrium
Large vessels that carry blood away from heart
Arteries
The sound made by the heart valves during atrial contraction
Lub
Oxygenated blood is found on which side of the heart
Left
Contractions in these muscles helps to push blood through the veins and back to heart
Skeletal
Receives a signal from the SA node and initiates ventricular contraction
AV node
The heart is able to beat without control of the brain- therefore, heartbeat is said to be
Intrinsic
Relaxation of the heart muscle- lowest arterial blood pressure
Diastole
Largest artery
Aorta
Membrane which surrounds heart
Pericardium
Smaller blood vessels which carry blood back to the heart
Venules
The pulmonary arteries carry blood to
Lungs
Occurs on the right side of heart
Pulmonary circulation
Takes blood from small intestines to liver
Heptic Portal vein
Returns blood from the parts of the body that are below the heart
Inferior vena cava
The percentage of blood in the arteries at any one time
Twenty
The most muscular of the heart chambers
Left ventricle
Take blood to and from kidneys
Renal arteries and veins
Separates the right atrium and ventricle
Right atrioventricular valve
