Identify Q

Left ventricle

The cardiovascular system consists of what?

heart, blood and all blood vessels

This is the body's pump which circulates blood throughout the body via the blood vessels.

The heart

This is the pointed inferior portion of the heart.

Apex

This is the superior portion of the heart where the blood vessels enter and leave.

Base

This is the connective tissue "sack" that contains and protects the heart. Its a serous membrane, secreting serous fluid to reduce friction and prevent sticking.

Pericardium

This layer of the pericardium covers the surface of the heart and is also known as the epicardium.

Visceral pericardium

This layer of the pericardium is the most outer.

Parietal Pericardium

This is an inflammation of the pericardium.

Pericarditis

This layer of the heart is the muscle layer and is composed of cardiocytes.

Myocardium

In the myocardium, the cardiocytes (heart cells) are connected by what?

intercalated discs

This layer of the heart is the most inner lining, of the chambers of the heart and continuous into the blood vessels. Its made of simple squamous epithelium.

Endocardium

This kind of circulation has blood flow from the heart to lungs and back for oxygenation.

Pulmonary circulation

This kind of circulation has blood flow from heart to body and back.

Systemic circulation

This kind of circulation has blood flow from the muscle tissues of the heart.

Coronary circulation

These are the lower chambers of the heart.

Ventricles

These are the upper chambers of the heart.

Atria

This is the wall that divides the atria.

Interatrial septum

This vein is both superior and inferior, brings deoxygenated blood from the body to the right atrium.

Superior and Inferior Vena cava

These veins bring oxygenated blood from the lungs to the left atrium.

Pulmonary veins

This takes oxygenated blood from the left ventricle to the body.

Aorta

This takes deoxygenated blood from the right ventricle to the lungs.

Pulmonary trunk

These are 'flaps' on the outside of the atria, they allow the atria to expand.

Auricles

This is the valve between the right atria and ventricle, ensures one-way flow of blood.

Tricuspid valve

This is the valve between the left atria and ventricle, ensures one-way flow of blood.

Bicuspid valve

This is the valve between the left ventricle and aorta, it ensures a one-way flow of blood.

Pulmonary semilunar valve

This is the muscle ridges lining the atria.

Pectinate muscles

In fetal development, this is what allows the blood to bypass the lungs. After birth, it closes leaving a depression.

Fossa (foramen) Ovalis

This literally means "heart strings". They anchor the valves to the ventricle wall to ensure that they don't invert during ventricular contractions.

Chordae tendinea

This is the muscle to which the chordae tendonae anchor.

Papillary muscle

This is the band of muscle that allows electrical signals to pass from the interventricular septum to the muscle of the right ventricle.

Moderator band

One complete heartbeat is known as what?

cardiac cycle

The contraction phase of a chamber is what?

Systolic

The relaxation phase of a chamber is what?

Diastole

The heart sound that a heart beat gives off is commonly reffered to as what?

Lub Dub

The "Lub" of the heart beat is when what happens?

closure of the AV valves

The "Dub" of the heart beat is when what happens?

Closure of the semilunar valves
