1

heart

the pump in the cardiovascular system

2

blood vessels

a network of pipes in the cardiovascular system

3

pericardium

a double-layered protective sac the surrounds the heart

4

arteries

a basic type of blood vessel that carry blood away from the heart

5

veins

a basic type of blood vessel that carries the blood towards the heart

6

capillaries

basic type of blood vessels, between arteries and veins, the smallest type of blood vessel

7

arterioles

arteries that have branched into smaller vessels

8

capillary beds

get blood delivered by arterioles, composed of a network of the smallest blood vessel (capillaries) and are the site of substance exchange between he blood and interstitial fluid

9

venules

blod drains from the capillary beds into the smalls veins

10

right atrium

on the left side of the picture, top chamber

11

right ventricle

the v-shaped chamber on the bottom left side of the picture

12

left atrium

the chamber on the top on the right side of the picture

13

left ventricle

the v-shaped chamber on the bottom right side of the picture...more muscular side of the heart (more muscular ventricle)

14

cusps

strong fibrous tissue flaps that form the four valves inside the heart

15

atrioventricular (AV) valves

located between an atrium and ventricle (bicuspid/mitral on the left side of the heart/right side of picture and tricuspid on the right side of the heart and the left side of the picture)

16

semilunar valves

(the pulmonary valve between the right ventricle and the pulmonary artery) (the aortic valve between the eft ventricle and the aortic arch) located between a ventricle and a great vessel

17

pulmonary circuit

the right side of the heart pumps deoxygenated blood to the lungs for oxygenation and then back to the left side of the heart

18

systemic circuit

the left side of the heart pumps oxygenated blood to the organs, tissues, cells of the body and then back to the right side of the heart

19

heart murmur

occurs when a valve doesn't completely close, allowing a small amount of blood to return to the previous area

20

diastole

a relaxation phase during which the heart chambers fill with blood

21

systole

a contraction phase during which the heart ejects blood

22

pulse

as the surge of blood that has been ejected front he heart moves through the blood vessels, it can be palpated in the arteries that are reasonably close to the surface of the body

23

blood pressure

the pressure exerted by blood against the walls of the blood vessels

24

systolic pressure

the higher number, produced as ventricles contract to eject a fresh bolus of blood into the major arteries

25

diastolic pressure

the lower number, the blood pressure when ventricle relax

26

sphygmomanometer

a blood pressure cuff machine, measures (mm Hg)

27

coronary

"heart" related

28

flow of blood

from body to vena cava, right atrium, tricuspid valve, right ventricle, pulmonic valve, pulmonary artery, lungs, pulmonary veins, left atrium, bicuspid valve, left ventricle, aortic valve, aortic arch, aorta, body [pulmonary artery carries deoxygenated blood away from heart, pulmonary veins carry oxygenated blood to the heart]

29

Algae

a generic term to describe a number of different plant-like protists

30

characteristics that algal group characteristics have been based on

pigments, cell wall, chemistry, food storage compounds, and presence or absence of flagella
