Glossary
- Arteries
- The arteries are vessels whose walls
are formed by three layers (inner layer
or endothelium, middle layer and
outer layer or adventitia), with a
predominance of fibers muscle and
elastic fibers in the middle layer.

- Cardiovascular system.
- The cardiovascular system
consists of the heart and blood
vessels: arteries, veins and
capillaries.
- The cardiovascular system
consists of the heart and blood
vessels: arteries, veins and
capillaries.
- Blood vessels.
- They form a network of ducts that carry
blood from the heart to the tissues and
from the tissues to the heart.
- They form a network of ducts that carry
blood from the heart to the tissues and
from the tissues to the heart.
- Arterioles.
- The arterioles are small arteries
whose function is to regulate the
flow to the capillaries.
- The arterioles are small arteries
whose function is to regulate the
flow to the capillaries.
- Repolarization.
- Recovering the resting membrane potential is due to the opening of potassium channels and the
closing of calcium channels.
- Recovering the resting membrane potential is due to the opening of potassium channels and the
closing of calcium channels.
- Cardiac cycle.
- A cardiac cycle includes all electrical
phenomena (action potential and its
propagation) and mechanical
(systole: contraction; diastole:
relaxation)
- A cardiac cycle includes all electrical
phenomena (action potential and its
propagation) and mechanical
(systole: contraction; diastole:
relaxation)
- Preload or degree of stretching.
- Of myocardial fibers during diastole
determines the strength of
myocardial contraction.
- Of myocardial fibers during diastole
determines the strength of
myocardial contraction.
- Afterload.
- It is the pressure that must overcome
the ventricle during systole to open the
atrioventricular valves.
- It is the pressure that must overcome
the ventricle during systole to open the
atrioventricular valves.
- Heart Rate.
- Is the number of times the heart
contracts in one minute (bpm). Proper
heart rate is essential for the proper
functioning of the heart.
- Is the number of times the heart
contracts in one minute (bpm). Proper
heart rate is essential for the proper
functioning of the heart.
- Depolarization.
- When excitation fibers sinus node arrives
to atrial fibers causes the rapid opening of
the sodium channels, which starts the
rapid depolarization.
- When excitation fibers sinus node arrives
to atrial fibers causes the rapid opening of
the sodium channels, which starts the
rapid depolarization.
- Blood pressure.
- Blood pressure is the hydrostatic
pressure of the blood against the
vessel wall containing it.
- Blood pressure is the hydrostatic
pressure of the blood against the
vessel wall containing it.
- Cardiac output.
- Is the amount of blood pumped by
the heart into the aorta each
minute.
- Is the amount of blood pumped by
the heart into the aorta each
minute.
- Blood flow.
- Is the volume of blood flowing through any
tissue per unit time (ml / min). The total
blood flow is the cardiac output.
- Is the volume of blood flowing through any
tissue per unit time (ml / min). The total
blood flow is the cardiac output.
- Arterial anastomosis:
- It is the union of two arterial
branches that supply the same
region.
- It is the union of two arterial
branches that supply the same
region.
- Cardiac muscle.
- Infarction or heart muscle consists of
striated muscle fibers shorter and less
circular than skeletal muscle fibers.
- Infarction or heart muscle consists of
striated muscle fibers shorter and less
circular than skeletal muscle fibers.
- Arteriovenous anastomoses:
- Is direct communication between an
artery and a venule so that no blood flows
through the capillary network.
- Is direct communication between an
artery and a venule so that no blood flows
through the capillary network.
- Stroke volume
- Is the volume of blood pumped
by a ventricle in shrinkage.
- Is the volume of blood pumped
by a ventricle in shrinkage.
- Anastomosis.
- It is called anastomosis to
the union of two or more
vessels.
- It is called anastomosis to
the union of two or more
vessels.
- Plateau.
- In a second phase, slow calcium channel that
open facilitate the entry of calcium ions into
myocardial fiber.
- In a second phase, slow calcium channel that
open facilitate the entry of calcium ions into
myocardial fiber.
- Vascular resistance.
- Vascular resistance is the force that resists the
flow of blood, primarily as a result of this friction
against the vessel wall.

flow of blood, primarily as a result of this friction
