Circulatory System

Question 1

Is the primary method used to transport nutrients and gases throughout the body. It is made up of blood, blood vessels and the heart.

Answer 1

Circulatory System

Question 2

What are the two main types of circulatory system?

Answer 2

Open and Closed Circulatory System

Question 3

In this circulatory system, blood vessels transport all fluids into a cavity.

Answer 3

Open Circulatory System

Question 4

Arthropods– including insects, crustaceans, and most mollusks– have this type of circulatory system.

Answer 4

Open Circulatory System

Question 5

In this circulatory system, the blood is not enclosed in blood vessels but is pumped into an open cavity called a hemocoel and is called hemolymph because the blood mixes with the interstitial fluid.

Answer 5

Open Circulatory System

Question 6

In an open circulatory system, the blood is not enclosed in blood vessels but is pumped into an open cavity called a ________ and is called hemolymph because the blood mixes with the interstitial fluid.

Answer 6

Hemocoel

Question 7

In an open circulatory system, the blood is not enclosed in blood vessels but is pumped into an open cavity called a hemocoel and is called _________ because the blood mixes with the interstitial fluid.

Answer 7

Hemolymph

Question 8

As the heart beats and the animal moves, the hemolymph circulates around the organs within the body cavity and then reenters the hearts through openings called _____.

Answer 8

Ostia

Question 9

In this circulatory system, blood never leaves the blood vessels. Instead, it is transferred from one blood vessel to another continuously without entering a cavity.

Answer 9

Closed Circulatory System

Question 10

All vertebrate animals have this type of circulatory system.

Answer 10

Closed Circulatory System

Answer 24

Platelets

Question 25

What are the 2 types of circulation?

Answer 25

Pulmonary and Systematic Circulation

Question 26

This circulation carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated blood back to the heart.

Answer 26

Pulmonary Circulation

Question 27

This circulation carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.

Answer 27

Systematic Circulation

Question 28

This circulatory system has no arteries to increase BP, therefore, has more blood at low pressure.

Answer 28

Open Circulatory System

Question 29

This circulatory system requires less energy for distributing blood.

Answer 29

Open Circulatory System

Question 30

This circulatory system carries blood at high pressure and delivers blood quickly.

Answer 30

Closed Circulatory System

Question 31

This circulatory system is suitable for animals with fast metabolism.

Answer 31

Closed Circulatory System

Answer 32

Single loop

Question 33

Mammals that have a double loop circulatory system.

Answer 33

Double loop

Question 34

In a ______ loop system, blood only passes through the the heart one type on each circuit through the body.

Answer 34

Single loop

Question 35

The evolution of the ______ circulatory loop allows more oxygen to be delivered to their bodies.

Answer 35

Double (second) loop

Question 36

In the circulatory loop that connects an amphibian’s heart to its lungs there are blood vessels called?

Answer 36

Pulmonary Veins

Question 37

Are the vessels that carry the oxygen-rich blood from the amphibian’s lungs directly back to its heart.

Answer 37
