Cardiovascular System

Question 1

closed system

Answer 1

BLOOD pumped throughout body by heart via arteries, veins, and capillaries

Question 2

open lymphatic system

Answer 2

has LYMPH that bathes interstitial spaces between cells and is circulated through lymph vessels

Question 3

closed, double looped

Answer 3

• has thick walled ARTERIES that transport blood AWAY from heart
• thin wall veins: transport blood TO heart

Question 4

capillaries

Answer 4

made of single layer of endothelium that form a network that connects arteries to veins in tissue
-exchanges of gas occur here and alveoli

Question 5

pulmonary loop

Answer 5

carries DEOXYGENATED blood from RIGHT ventricles to lungs and return oxygen blood to LEFT ATRIUM

Question 6

systemic loop

Answer 6

carries OXYGENATED blood from LEFT ventricles to body, returning deoxygenated blood to RIGHT ATRIUM

Question 7

capillary beds

Answer 7

• smallest tubules; SLOWEST

- diffusion site for exchange between BLOOD and INTERSTITIAL FLUIDS

Question 8

atrial contraction

Answer 8

FIll ventricles

Question 9

ventricular contraction

Answer 9

EMPTIES ventricles, forcing circulation

Question 10

lymphatic system

Answer 10

return excess tissue fluid to bloodstream

Question 11

lymph vessels

Answer 11

• (like veins) thin-walled

- has 1 valve

Question 12

lymph capillaries

Answer 12

intertwined with cardiovascular capillaries and absorb excess tissue fluid and blood

Question 13

lymph nodes

Answer 13

filter through 100s of small organs

Question 14

BP average

Answer 14

120/80 - 140/90

Question 15

systole

Answer 15

• contraction

- causes blood to push against muscular wall of arteries to max pleasure

Question 16

diastole

Answer 16

• relaxation
• elasticity in vessels wall recoil and pressure decrease

Question 17

What is the functions of the cardiovascular system?

Answer 17

• TRANSPORTING nutrients, waste, chemical messengers, and immune molecules

Question 18

portal circulation

Answer 18

flow of blood from DIGESTIVE SYSTEM –> LIVER –> HEART

Question 19

renal circulation

Answer 19

flow of blood between HEART and KIDNEY

Question 20

coronary circulation

Answer 20

flow of blood between HEART and TISSUE

Question 21

Lienorenal ligaments

Answer 21

Kidney —> spleen

Question 22

Spleenic sinuses

Answer 22

Spleen —> blood vessels

Question 23

aneursm

Answer 23

localized abnormal, weak spot on blood vessel wall that causes an outward bulging, likened to a bubble or balloon
-HEMORRHAGE occurs when it bursts

Question 24

atherosclerosis

Answer 24

narrowing of arteries due to plaque buildup on artery walls

Question 25

anemia

Answer 25

not enough healthy rbc
