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 ECG
The medial cavity of the thorax that contains the heart is called the...
mediastinum
What type of blood vessel facilitates gas and nutrient exchange?
capillaries
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
The double walled sac that encloses the heart is called the ___________________.
pericardial sac or pericardium
What are the layers of the heart from deep to superficial?
endocardium, myocardium, epicardium, pericardium
What chamber of the heart pumps deoxygenated blood to the lungs so that it can pick up oxygen?
right ventricle
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 is the muscular layer of the heart that is responsible for the heart contracting. This is the thickest layer of the heart.
Myocardium
What has three flexible cusps and separates the right atrium from the right ventricle?
tricuspid valve
From which chamber of the heart does blood leave to go to the body?
left 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 amount of blood pumped out by the ventricles in one minute is the heart's _____________________.
Cardiac Output
The blood-containing space of a blood vessel is called the...
vessel lumen
A person with chest pain that radiates to their left shoulder, neck, and jaw comes to the ER. They are sweaty, and hypotensive. The EKG showed ST elevations, what is your diagnosis?
myocardial infarction, heart attack
