1

Location of the heart

In the mediastinum between the lungs

2

The base of the heart is what portion? And located where?

It is the broad superior portion and is located behind the rest of the heart

3

The heart tapers to a point known as...

The apex

4

The apex is what portion of the heart?

The inferior portion

5

The four chambers of the heart are

The right atrium, right ventricle, left atrium and left ventricle

6

System related to the right side of the heart

Pulmonary system

7

What side of the heart contains deoxygenated blood?

The right side

8

Blood from the right side of the heart goes where and undergoes what?

It goes to the lungs and undergoes gas exchange

9

What system is related to the left side of the heart?

The systemic system

10

What side of the heart contains oxygenated blood?

The left side

11

The internal features of the heart are

The pericardium and the heart wall

12

What makes up the pericardium and the heart wall

Pericardial cavity, parietal pericardium, visceral pericardium, myocardium and endocardium

13

Fibrous pericardium function

Allows the heart to beat in a frictionless motion

14

Serous pericardium function

Lines the sac, covers the heart and allows the heart to beat in a smooth motion

15

What is the myocardium

A thick muscular layer which is part off the fibrous skeleton

16

What is the endocardium

The smooth lining of the heart

17

What is the fossa ovalis

A thumb shaped impression on the right atrium

18

What was the function of the fossa ovalis

It was an opening during development that allowed direct blood flow from the right to the left atrium because the lungs were not developed

19

Muscular ridges in the atrium are known as

Masculi pectinati

20

Muscular ridges in the ventricles are known as

Trabecular carneae

21

Rounded muscular projections found in the ventricles are known as

Papillary muscles

22

Function of the chordae tendineae

Muscles attached along the edges of the valves to prevent the vales from opening up under high pressure

23

External features of the heart

Superior vena cava, ascending aorta, right auricle, right atrium, right ventricle, inferior vena cava, apex of the heart, left ventricle, left auricle, left atria, pulmonary trunk, left pulmonary artery, left pulmonary veins, coronary sinus, right pulmonary artery, right pulmonary veins and the arch of the aorta

24

What does the pulmonary trunk branch into

The pulmonary artery

25

What arteries supply the heart with blood

The coronary arteries. The left coronary artery branches into the circumflex branch and the anterior interventricular branch

26

Veins that drain the heart tissue

The cardiac veins

27

What are the three cardiac veins

The great, the middle and the small

28

Where is the great cardiac vein located

The anterior aspect of the heart

29

Where are the middle and small cardiac veins located

On the posterior aspect of the heart.

30

What vessels return blood to the coronary sinus

The middle and small cardiac veins
