Deoxygenated blood

Question 5

Right Ventricle pumps blood to

Answer 5

Pulmonary trunk (right and left pulmonary articles)

Question 6

Coronary Sinus receives blood from

Answer 6

Pericardium (heart walls)

Question 7

The only arteries that carry de-oxygenated blood

Answer 7

Right and left pulmonary articles

Question 8

Left Atrium receives blood from

Answer 8

Pulmonary veins

Question 9

The only veins that carry oxygenated blood

Answer 9

Pulmonary veins

Question 10

Aorta

Answer 10

Branches and sends blood to the rest of the body

Question 11

(Coronary) Cardiac Arteries

Answer 11

First left and right minor branches of aorta feed oxygenated blood to the heart

Question 12

(Coronary) Cardiac Veins

Answer 12

Collect blood form the heart tissues and open into a large vein called the coronary sinus

Question 13

3 Main Branches of the Aorta Arch

Answer 13

Left Common Carotid Artery
Left Subclavain Artery
Brachiocephalic Artery

Question 14

Left Common Carotid Artery

Answer 14

First Branch from the aorta that takes oxygenated blood to the head and neck

Question 15

Left Subclavian Artery

Answer 15

Branch that sends oxygenated blood to the left arm

Question 16

Brachiocephalic Artery

Answer 16

Main branch that splits to form the Right Common Carotid Artery and the Right Subclavian Artery that take oxygenated blood to the head/neck and right arm

Question 17

The Aorta Arch continues on to form the

Answer 17

Thoracic and Abdominal aortic arteries that suppy oxygenated blood to the entire lower body

Question 18

Artery

Answer 18

Strong, elastic vessels that carry blood away from the heart under high pressures (mainly oxygenated blood)

Question 19

Arteriotes

Answer 19

Small branches off of arteries

Question 20

Capillaries

Answer 20

Small branches off of arteriotes, meet up with the cell membranes of tissue cells in the body and alveolar cells (air sacs) in the lungs

Question 21

Gas exchange

Answer 21

simple diffusion of O2 and CO2 that happens between the slits of the epilthealial cells

Question 22

Gas exchange in the lungs

Answer 22

Oxygen enters the blood; carbon dioxide leaves the blood

Question 23

Gas exchange in the body

Answer 23

Carbon dioxide enters the blood; oxygen leaves the blood

Question 24

Pulse

Answer 24

Expansion and recoil of the artery walls caused by the increase pressure created by the heart pumping

Question 25

Blood is moved by

Answer 25

Muscle contraction Pressure created through breathing One way valves that prevent backflow

Question 26

Cardiac Conduction System

Answer 26

Clusters of muscle fibers that do not contract, but act to spread impulses throughout the heart

Question 27

Sinatrial node

Answer 27

(S-A Node) located in right atrium, without nerve stimulation these cells conduct impulses that spread to other cardiac fibers causing them to contract

Question 28

Sinatrial node also known as

Answer 28

The pacemaker

Question 29

Atrioventricular Node

Answer 29

(A-V Node) located in inferior septum of atria, impusles travel slower allowing for the slight pause while the atria empty and the ventricles fill

Question 30

Purkinje Fibers

Answer 30

Connects to papillary muscles in the walls of the ventricles to stimulate ventricular contraction
