Cardiovascular

Question 1

Arteries

Answer 1

The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body.

Question 2

Blood vessels

Answer 2

Blood vessels are channels that carry blood throughout your body.

Question 3

Capillaries

Answer 3

Capillaries (CAP-uh-lair-eez) are tiny blood vessels that transport blood, nutrients and oxygen to cells in your organs and body systems.

Question 4

Deoxygenated

Answer 4

Deoxygenated is defined as oxygen has been removed

Question 5

Heart

Answer 5

The task of your heart is to pump enough blood to deliver a continuous supply of oxygen and other nutrients to the brain and the other vital organs.

Question 6

Oxygen

Answer 6

Oxygen is the chemical element with the symbol O and atomic number 8

Question 7

Oxygenated

Answer 7

Oxygenated chemical compounds contain oxygen as a part of their chemical structure.

Question 8

Pulmonary circulation

Answer 8

Pulmonary circulation includes a vast network of arteries, veins, and lymphatics that function to exchange blood and other tissue fluids between the heart, the lungs, and back.

Question 9

Systemic circulation

Answer 9

The systemic circulation provides the functional blood supply to all body tissue. It carries oxygen and nutrients to the cells and picks up carbon dioxide and waste products.

Question 10

Veins

Answer 10

Veins are blood vessels in humans, and most other animals that carry blood towards the heart.

Question 11

Size of heart

Answer 11

The heart weighs between 7 and 15 ounces

Question 12

How many chambers does the heart have?

Answer 12

A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood.

Question 13

Location of heart

Answer 13

Your heart is located in the front of your chest. It sits slightly behind and to the left of your sternum

Question 14

Apex

Answer 14

the tip of a pyramidal or rounded structure, such as the lung or the heart

Question 15

Endocardium

Answer 15

The endocardium is the innermost layer of the heart and lines the chambers and extends over projecting structures such as the valves, chordae tendineae, and papillary muscles.

Question 16

Myocardium

Answer 16

Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle. It is involuntary, striated muscle that constitutes the main tissue of the wall of the heart.

Question 17

Pericardium

Answer 17

The pericardium is a membrane, or sac, that surrounds your heart. It holds the heart in place and helps it work properly.

Question 18

Atria

Answer 18

The atrium (Latin: ātrium, lit. ‘entry hall’) is the upper chamber through which blood enters the ventricles of the heart.

Question 19

Ventricles

Answer 19

each of the two main chambers of the heart, left and right.

Question 20

Tricuspid valve

Answer 20

The tricuspid valve is on the right side of the heart. It separates the upper and lower chambers, also known as the right atrium and ventricle.

Question 21

Pulmonary valve

Answer 21

The pulmonary valve is one of four valves that regulate blood flow in the heart. The valve lies between the lower right heart chamber (right ventricle) and the pulmonary artery.

Question 22

Mitral valve

Answer 22

the valve between the left atrium and the left ventricle of the heart, consisting of two tapered cusps

Question 23

Aortic valve

Answer 23

The aortic valve—the main outflow valve for the left heart—is the valve between the heart and the body
