Cardiovascular System

Question 1

What is the cardiovascular system?

Answer 1

Heart, blood and blood vessels

Question 2

Cardiovascular components

Answer 2

Heart
Blood vessels
Blood

Question 3

What makes up the blood vessels

Answer 3

Arteries, veins and capillaries

Question 4

Where is the heart located

Answer 4

In the mediastinum within its own cavity

Question 5

Where is the ventral mediastinum

Answer 5

Between ribs 3-7; almost entirely surrounded by lungs

Question 6

Cardiac notch

Answer 6

Area on the right side exposed to chest wall( no lungs surrounding)

Question 7

Pericardial sac in cattle

Answer 7

Is in contact w/touches the diaphragm

Question 8

Base

Answer 8

The wider part of the heart toward the top/more cranial

Question 9

Apex

Answer 9

Pointier part of the heart towards the bottom;consists mostly of the left ventricle

Question 10

Fibrous pericardium

Answer 10

Separated from visceral pericardium by a space

Question 11

Visceral pericardium

Answer 11

Epicardium

Question 12

3 layers of the heart wall

Answer 12

Epicardium-outermost layer
Myocardium-the heart muscle itself
Endocardium-inner most layer; lines the chamber walls

Question 13

Grooves

Answer 13

Coronary groove
Interventricular groove

Question 14

Coronary groove

Answer 14

Groove around the base of the heart to superficially separate the two atria from the two ventricles

Question 15

Interventricular groove

Answer 15

Comes down from the coronary groove at an angle to superficially separate the two ventricles

Question 16

Red blood vessels

Answer 16

Blood is well oxygenated;arterial

Question 17

Blue blood vessels

Answer 17

Blood is not well oxygenated; venous

Question 18

Cranial and caudal vena cava

Answer 18

Responsible for bringing venous blood FROM the body TO the right atrium

Question 19

Pulmonary arteries

Answer 19

Responsible for bringing blood FROM the right ventricle TO the lungs. This artery starts as one “trunk” and splits in two

Question 20

Pulmonary veins

Answer 20

Responsible for bringing blood FROM the lungs TO the left atrium

Question 21

Aorta

Answer 21

Responsible for bringing blood FROM the left ventricle TO the rest of the body( not lungs)

Question 22

Heart chambers

Answer 22

R side-deals w/deoxygenated blood
L side- deals w/oxygenated blood

Question 23

Right atrium

Answer 23

Main chamber
Auricle
Blood flow: cranial/caudal vena cava

Question 24

Right ventricle

Answer 24

Blood flows from RA to RV; RV recieves the deoxygenated blood and pumps it into the pulmonary artery for the blood to become oxygenated in the lungs

Question 25

Left atrium

Answer 25

Freshly oxygenated blood comes from the lungs into the left atrium via pulmonary veins

Question 26

Left Ventricle

Answer 26

Bloood flows from LA to LV and then on to the aorta; then goes to the body

Question 27

Coronary circulations

Answer 27

Blood flow to the heart not through Coronary arteries Interventricular coronary veins Coronary sinus

Question 28

Coronary sinus

Answer 28

Opening through which venous blood from IVV can flow into the RA

Question 29

Septum’s

Answer 29

Walls that separate chambers of the heart

Question 30

Interatrail septum

Answer 30

Septum between 2 atria

Question 31

Interventricular septum

Answer 31

Septum between 2 ventricles

Question 32

Valves

Answer 32

Aid the flow of blood in the correct direction by opening and closing
