2

arteries

take blood away from heart (red)

3

1. Blood from the body returns via....

the inferior and superior vena cava to the right atrium

4

2. Blood passes through the tricuspid valve and enters the.....

right ventricle

5

3. Next blood passes through the pulmonary _______ to the pulmonary _______, to the lungs, and back to the heart through the ____________.

-valve
-trunk
-pulmonary veins

6

4. Blood enters the left atrium, passes through the _____________to enter the ____________

-bicuspid
-left ventricle

7

5. From the left ventricle, blood leaves through the ________ to enter the _______.

-aortic valve
-aorta

8

Interventricular sulcus

contains coronary blood vessels and marks the ventral surface of the heart

9

left ventricle

the left side feels thicker and more solid because of its greater muscle mass

10

the aorta exits...

the left ventricle

11

Arteries that branch of the aorta

brachiocephalic artery
Left common carotid
Left subclavin

12

Papillary muscles

hill-like structures that connect the chord tendinae to the heart wall. When they contract, they help maintain the valve against various pressure

13

CHAMBERS of the human heart:

right atrium, left atrium, right ventricle, left ventricle

14

VESSELS of the human heart:

aorta, pulmonary trunk, superior vena cava, inferior vena cava, brachiocephalic artery, left common carotid artery, left subclavin artery, pulmonary veins

15

VALVES of the human heart:

tricuspid valve, bicuspid valve, pulmonary valve, aortic valve

16

OTHER STRUCTURES of the human heart:

right auricle, left auricle, inter ventricular sulcus, papillary muscles, chordae tendinae

17

What vessels does the sheep heart lack?

brachiocephalic artery, left common carotid artery, left subclavin artery, pulmonary veins

18

veins entering the heart

these are located posterior to the heart...
superior vena cava
inferior vena cava

19

Superior vena cava

returns blood from head and forearms

20

inferior vena cava

returns blood from abdomen and hind legs

21

Veins supplying the superior vena cava from the arm...

brachiocephalic vein
subclavin vein
axillary vein
brachial vein

22

Brachiocephalic vein

supplied by the subclavian vein

23

subclavian vein

supplied by the axillary vein

24

Axillary vein

supplied by the brachial vein

25

Branches feeding the brachiocephalic vein from the cranium

External jugular vein
Internal jugular vein

26

External jugular vein

Enters at junction between brachiocephalic veins and subclavian vein

27

Internal jugular vein

Small, may be torn

28

systematic arteries (except pulmonary artery) are filled with...

red latex

29

The left subclavian artery leaves the thoracic cavity and enters the left arm as the _____________.

axillary vein

30

Arteries emerging from the heart

Aorta
Pulmonary artery

long thoracic
subscapular
anterior humeral circumflex
deep brachial
brachial

34

Vertebral artery

36

Costocervical artery

Supplies the costal and cervical regions

37

Thyrocervical artery
