Circulatory System 1
The __________ side of the heart delivers blood to all parts the body except the lungs.
left
Which type of blood vessel has a 'pulse'?
artery
Which type of blood vessel has valves inside?
Vein
Which side of the heart manages the flow of deoxygenated blood?
The right side
3 categories of blood vessels
veins, arteries and capillaries
The outermost layer of the heart is the __________. It serves to help protect the heart from damage. This layer of the heart also contains the blood vessels that supply oxygen to the heart muscle so it can function.
epicardium
The primary job of the pulmonary circuit is to
oxygenate blood
which circuit transports deoxygenated blood from the heart to the lungs, and is returned to the heart as oxygenated blood?
Pulmonary circuit
What measures the electrical activity of the heart, and it is used to diagnose problems with the electrical functioning of the heart.
electrocardiogram, or EKG/ECG
How many "circuits" are in the circulatory system?
Three
Between the two sides of the heart is the _________. It divides the heart into right and left and separates the deoxygenated blood from the oxygenated blood. The function of separating the blood is important because the heart would not be able to work as efficiently if the blood were to mix.
septum
Cardiac Arrest
This diagnostic test tests the heart's function when it is under stress, such as during exercise. In a stress test, you will have to walk on a treadmill while I measure your heart's function with an ECG.
stress test
The large veins that return blood to the heart.
Superior and Inferior vena cava
Usually, (with the exception of veins leading from the lungs) the blood flowing in veins is rich or poor in oxygen?
poor
This is the throbbing of your arteries as blood moves through them. You can use this to measure your heart rate, the number of times your heart beats in one minute. A normal heart rate for a person at rest is 60 to 100 beats per minute.
pulse
Which node of cardiac conduction BEGINS the charge of electrcity in the heart?
The middle layer of the heart is the ______________. It gets its name because myo- means muscle. It is the muscular layer of the heart that is responsible for the heart contracting. This is the thickest layer of the heart.
Myocardium
What is the alternative name of a Red Blood Cell and what protein do they use to carry 02
Erythrocyte(s), Hemoglobin
From which chamber of the heart does blood leave to go to the lungs?
right ventricle
These blood vessels bring oxygenated blood from the lungs into the left atrium.
The pulmonary veins
These blood vessels carry deoxygenated blood from the right ventricle to the lungs.
The pulmonary arteries
The ventricle walls contract when electrical charge reaches these special fibers
Perkinje Fibers
which circuit transports oxygenated blood from the heart to the different parts of the body. This blood then returns to the heart as deoxygenated blood.
Systemic circuit
The atrioventricular node must send an electric impulse through this special bundle of fibers BEFORE the impulse can reach the Purkinje fibers in the ventricular walls.
Bundle of HIS
