NORMAL STRUCTURE AND FUNCTION

Cardiovascular System

aorta a-OR-ta

The largest artery. It receives blood from the left ventricle and branches to all parts of the body (root aort/o).

aortic valve a-OR-tik

The semilunar valve at the entrance to the aorta

a_pex

A-peks

The point of a cone-shaped structure (adjective, apical). The apex of the heart is formed by the left ventricle. It is inferior and pointed toward the left (see Fig. 9-2).

artery

A vessel that carries blood away from the heart. All except the pulmonary and umbilical arteries carry oxygenated blood (root arter, arteri/o).

arter_iol_e_

ar-TE-re-ol

A small artery (root arteriol/o)

atriov_entricular (AV) node a-tre-o-ven-TRIK-u-lar

A small mass in the lower septum of the right atrium that passes impulses from the sinoatrial (SA) node toward the ventricles

AV bundle

A band of fibers that transmits impulses from the atrioventricular (AV) node to the top of the interventricular septum. It divides into the right and left bundle branches, which descend along the two sides of the septum; the bundle of His.

a_trium

A-tre-um

An entrance chamber, one of the two upper receiving chambers of the heart (root atri/o)

bicuspid valve bi-KUS-pid

The valve between the left atrium and the left ventricle; the mitral valve

blood pressure

The force exerted by blood against the wall of a vessel

bundle branches

Branches of the AV bundle that divide to the right and left sides of the interventricular septum

capillary _

KAP-i-lar-e

A microscopic blood vessel through which materials are exchanged between the blood and the tissues

cardio_v_ascular system kar-de-o-VAS-ku-lar

The part of the circulatory system that consists of the heart and the blood vessels

d_iastole__

di -AS-to-le

The relaxation phase of the heartbeat cycle

endo_cardium_

en-do-KAR-d e-um

The thin membrane that lines the chambers of the heart and covers the valves

epicardium_

ep-i-KAR-d e-um

The thin outermost layer of the heart wall

functional murmur

Any sound produced as the heart functions normally

Cardiovascular System, continued

heart

The muscular organ with four chambers that contracts rhythmically

hart

to propel blood through vessels to all parts of the body (root cardi/o)

heart sounds

Sounds produced as the heart functions. The two loudest sounds are

produced by alternate closing of the valves and are designated S: and S2.

in_ferior vena cava

The large inferior vein that brings blood back to the right atrium of

VE-na-KA-va

the heart from the lower part of the body

m_itral valve

The valve between the left atrium and the left ventricle; the bicuspid

MI-tral

valve

m_yo_cardium_

The thick middle layer of the heart wall composed of cardiac muscle

mi -o-KAR-de-um

pericardium_

The fibrous sac that surrounds the heart

per-i-KAR-de-um

pulmonary artery

The vessel that carries blood from the right side of the heart to the

PUL-mo-nar-e

lungs

pulmonary circuit

The system of vessels that carries blood from the right side of the

heart to the lungs to be oxygenated and then back to the left side of

the heart

pulmonary veins

The vessels that carry blood from the lungs to the left side of the

heart

pulmonic valve

The semilunar valve at the entrance to the pulmonary artery

pul-MON-ik

pulse

The wave of increased pressure produced in the vessels each time the

ventricles contract

Purkinje fibers

The terminal fibers of the conducting system of the heart. They carry

pur-KIN-je

impulses through the walls of the ventricles.

septum

A wall dividing two cavities, such as the chambers of the heart

SEP-tum

s_inoatr_ial _(SA) node

A small mass in the upper part of the right atrium that initiates the

si -no-A-tre-al

impulse for each heartbeat; the pacemaker

sphygmomanometer

An instrument for determining arterial blood pressure (root sphygm/o

sfig-mo-man-OM-e-ter

means "pulse"); blood pressure apparatus or cuff (see Fig. 9-4)

su_perior_ vena cava

The large superior vein that brings deoxygenated blood back to the

VE-na-KA-va

right atrium from the upper part of the body

systemic circuit

The system of vessels that carries oxygenated blood from the left side

sis-TEM-ik

of the heart to all tissues except the lungs and returns deoxygenated

blood to the right side of the heart

systo_le_

The contraction phase of the heartbeat cycle

SIS-to-le

Cardiovascular System, continued

tricuspid valve

The valve between the right atrium and the right ventricle

tri -KUS-pid

valve

A structure that keeps fluid flowing in a forward direction (root

valv/o, valvul/o)

v_ein

A vessel that carries blood back to the heart. All except the pulmonary

van

and umbilical veins carry blood low in oxygen (root ven, phleb/o).

ventricle

A small cavity. One of the two lower pumping chambers of the heart

VEN-trik-l

(root ventricul/o).

venul_e

A small vein

VEN-ul

vessel

A tube or duct to transport fluid (root angi/o, vas/o, vascul/o)

VES-el

Lymphatic System

lymph

The thin plasmalike fluid that drains from the tissues and is trans-

limf

ported in lymphatic vessels (root lymph/o)

lymph node

A small mass of lymphoid tissue along the path of a lymphatic vessel

that filters lymph (root lymphaden/o)

lymphatic system

The system that drains fluid and proteins from the tissues and re-

lim-FAT-ik

turns them to the bloodstream. This system also aids in absorption of

fats from the digestive tract and participates in immunity.

right lymphatic duct

The lymphatic duct that drains fluid from the upper right side of the

body

spleen

A large reddish-brown organ in the upper left region of the abdomen.

It filters blood and destroys old red blood cells (root splen/o).

thoracic duct

The lymphatic duct that drains fluid from the upper left side of the

body and all of the lower portion of the body

thym_ us gland

A gland in the upper part of the chest beneath the sternum. It func-

THI -mus

tions in immunity (root thym/o).

tonsils

Small masses of lymphoid tissue located in the region of the throat
