Flashcards in Circulatory System Deck (38):
1

the circulatory system includes

heart, blood vessels, blood

2

what do blood vessels do

carry blood all over and sometimes bring things to other parts of the body where they are needed

3

blood moves...

oxygen and nutrients to cells and carbon dioxide and other waste away from the cells

4

active transport...

does require energy

5

the heart is made of

cardiac muscle tissue

6

the heart is made of ___ chambers...

4

7

what are the names of the chambers

atriums and ventricles

8

the upper chambers are called

atriums

9

the lower chambers are called

ventricles

10

during a heartbeat...

both atriums pull at the same time

11

a _____ separates each ___ from the ____below it

one way valve
atrium
ventricle

12

a ____ prevents blood from flowing in between the _____ and ____

wall
atriums
ventricles

13

the sections of the circulatory system are:

pulmonary circ. coronary circ. systemic circ.

14

what brings blood from one section to the next

the beating of the heart

15

what supplies cells with oxygen and nutrients

the hearts blood vessels

16

what is the coronary system

the flow of blood to and from the heart

17

what happens if the coronary system is blocked and what can it result in?

oxygen and nutrients can't reach the heart and it can result in a heart attack

18

what is the pulmonary system and what does it do?

the flow of blood to and from the lungs

19

what does blood returning from the body through the right side contain?

cellular waste

20

what does the cellular waste include?

molecules of carbon dioxide and substances

21

what diffuses into the blood

oxygen

22

what side of the heart does the blood return to

the left

23

what is systemic circulation

oxygen rich blood moves to all the organs except the heart and lungs. oxygen poor blood returns to the heart. then, nutrients and oxygen are delivered by blood to your body cells for carbon dioxide and waste. then the blood returns to heart in the veins of systemic circ

24

what does blood move in

blood vessels

25

what makes blood move

the pumping of the heart

26

what are arteries

blood vessels that carry blood away from the heart

27

after blood is pumped out of the heart, what happens

it travels through artery capieries and then veins

28

arteries are made of:

thick elastic walls made of connective tissue and smooth muscle tissues

29

the ______ventricle is connected to the pulmonary artery

right

30

the left ventricle is connected to the

aorta

31

what is a vein

blood vessels that carry blood back to the heart

32

what happens if blood travels backwards

the pressure of the blood against the valve causes the valve to close

33

what is the flow of the veins helped by

skeletal muscles

34

what are 2 major veins called

superior vena cava and inferior vena cava

35

superior vena cava

returns blood from the head and nek

36

inferior vena cave

returns blood from lower part of body

37

capillaries...

connects the veins and arteries

38

what are some diseases for this system

heart attack, hemophilia, high cholesterol, coronary artery disease
