Circulatory System

Question 1

Why is this system called a “two-loop system”?

Answer 1

one loop to lungs, one loop to body

Question 2

Why does blood travel to the lungs?

Answer 2

to pick up o2 and drop off co2

Answer 3

arteries

Question 4

Which blood vessels carry blood TO the heart?

Answer 4

veins

Question 5

Where does oxygen poor blood go into?

Answer 5

Right Atrium

Question 6

What “pumps” blood?

Answer 6

ventricles

Question 7

What does the right ventricle pump blood to?

Answer 7

Pulmonary artery

Question 8

Where does the plumonary artery get blood to?

Answer 8

Lungs

Question 9

What vessel does the lungs give the oxygenated blood to?

Answer 9

Pulmonary Vein

Question 10

Where does the pulmonary vein drop off blood?

Answer 10

Left Atrium

Question 11

Where does the left atrium drain oxygen rich blood into?

Answer 11

Left Ventricle

Question 12

Where does the left ventircle pump oxygenated blood to?

Answer 12

Aorta

Question 13

Where does the aorta direct oxygen rich blood?

Answer 13

Body Tissues

Question 14

How many chambers are in the human heart?

Answer 14

4

Question 15

Which chambers collect blood?

Answer 15

atrium

Question 16

Which chambers pump blood?

Answer 16

ventricles

Question 17

Which is the ONLY artery in the body that pumps oxygen-poor blood?

Answer 17

pulmonary artery

Question 18

hormone

Answer 18

produced by endocrine glands and transported by the circulatory system

Question 19

lungs

Answer 19

the organ of the respiratory system that works with the circulatory system to deliver oxygen to and remove carbon dioxide from the tissues

Question 20

artery

Answer 20

blood vessel that carries blood AWAY from the heart
(artery, away)
It is a thick-walled and muscular vessel.

Question 21

Vein

Answer 21

blood vessel that carries blood TO the heart
(vein, to?)
thinner walls than arteries

Question 22

pulmonary artery

Answer 22

only artery in the body that carries low oxygen (deoxygenated) blood

Question 23

aorta

Answer 23

largest blood vessel of the body, carries oxygen-rich (oxygenated) blood to the tissues from the left ventricle

Question 24

nutrients

Answer 24

absorbed by digestive system and transported by the circulatory system

Question 25

heart

Answer 25

the highly coordinated force pump of the two-loop circulatory system, main organ of the circulatory system, works with everything in the body, contracts and relaxes constantly in order to do its job, beats around 100,000 times every day. Blood moves from the heart to the lungs and then back to the heart again before it is transported out to the body. Blood moving through the vessels allows for the exchange of gases and brings nutrients to all the cells.

Question 26

capillaries

Answer 26

Blood vessels divide into smaller and smaller branches until the tiniest (only as wide as one blood cell; Capillaries pass near every cell in the body) a tiny vessel where substances are exchanged between the blood and body cells. Capillaries can be thought of as connecting arteries and veins.

Question 27

Blood

Answer 27

Blood picks up oxygen from the lungs and food molecules from the intestines and delivers them to needy cells. At the same time, blood collects carbon dioxide and waste from the cells. The carbon dioxide is returned to the lungs to be released into the air. Waste products are filtered from the blood by the kidneys in the excretory system and passed out of the body in urine.

Question 28

Circulatory System

Answer 28

transports nutrients and other life-sustaining resources, ncludes the cardiovascular system and the lymphatic system, also removes waste products and helps to fight off diseases and infections.

Question 29

Cardiovascular System

Answer 29

the heart pumps blood through the body using the various blood vessels.

Question 30

Red Blood Cells

Answer 30

play a key role in transporting oxygen throughout the body. They take up oxygen in the lungs and deliver it to cells throughout the body. Red blood cells also absorb carbon dioxide in the body and transport it to the lungs, where it is released from the body.

Question 31

Blood Vessel

Answer 31

heart is connected to the rest of your body through a system of vessels, heart is connected to the rest of your body through a system of vessels,

Question 32

Diffusion

Answer 32

Oxygen and other materials move through capillary walls by diffusion. materials move from an area of high concentration to one of lower concentration

Question 33

Blood Pressure

Answer 33

The force with which ventricles of the heart contract is what creates blood pressure. This pumping action is what you feel when you are aware of your heartbeat or pulse. The pumping action of the ventricles is strong enough to push blood throughout your body.
