Q

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.

Q

45% of the blood is composed of?

A

RBC

21
Q

Carries oxygen from lungs to all cells of the body; carries carbon dioxide away from cells.

A

RBC

22
Q

Are the cells of the immune system that are involved in protecting the body against infection and foreign invaders.

A

WBC

23
Q

Liquid portion of the blood composed mostly of water. It transports nutrients, hormones, and proteins to the parts of the body.

A

Plasma

24
Q

For blood clotting and blood coagulation.

A

Platelets

25
Q

What are the 2 types of circulation?

A

Pulmonary and Systematic Circulation

26
Q

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

A

Pulmonary Circulation

27
Q

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

A

Systematic Circulation

28
Q

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

A

Open Circulatory System

29
Q

This circulatory system requires less energy for distributing blood.

A

Open Circulatory System

30
Q

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

A

Closed Circulatory System

31
Q

This circulatory system is suitable for animals with fast metabolism.

A

Closed Circulatory System

32
Q

Fish are vertebrates that have a ______ loop
circulatory system.

A

Single loop

33
Q

Mammals that have a double loop circulatory
system.

A

Double loop

34
Q

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

A

Single loop

35
Q

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

A

Double (second) loop

36
Q

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

A

Pulmonary Veins

37
Q

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

A

Pulmonary Veins

38
Q

Do sponges have a real circulatory system?

A

No

39
Q

Sponges have ___________ cells over the surface of their bodies, these are cells that have tails that wiggle.

A

Flagellated

40
Q

They do not have a circulatory system simply because it is not needed.

A

Cnidarians

41
Q

They do not obtain a circulatory system and are able to transfer the oxygen and the necessary nutrients for themselves by diffusion.

A

Nematodes

42
Q

Do annelids have an open or closed circulatory system?

A

Closed

43
Q

Do mollusks have an open or closed circulatory system?

A

Open

44
Q

Do anthropods have an open or closed circulatory system?

A

Open

45
Q

Do echinoderms have an open or closed circulatory system?
