Question
Chapter 44.1, Problem 2SB
Summary Introduction
To review:
The difference between an open and closed circulatory system and the reason behind the inability of humans to function with an open circulatory system.
Introduction:
Different organisms possess different kinds of circulatory systems, which have evolved into two different types of the circulatory systems, which are closed and open circulatory system. Open circulatory system is one where body tissues and organs are surrounded by a fluid called hemolymph. This type of circulatory system is mainly found in invertebrates except for earthworm. The closed circulatory system has blood vessels. These blood vessels run transversely through the body and transport oxygen and blood to different organs.

Which of the following is false about open circulatory systems?
Question 5 options:
a)
Movement of blood in an open circulatory system is relatively fast.
b)
Blood is in direct contact with all organs.
c)
Snails have an open circulatory system.
d)
There may be some blood vessels in organisms with open circulatory systems, but these tubes will not be closed on either end.
What is the main purpose of the circulatory system?
move blood throughout the body
move lymphatic fluid from the tissue to the heart
digest food
move blood and lymph throughout the body
An organism’s circulatory system functions in transport, delivering nutrients to cell and removing waste. The structure and efficiency of circulatory systems varies in different organisms.note whether the statements below are consistent with an open or closed circulatory system.
The circulating fluid flows in one direction (unidirectionally) through a circulatory loop.
The circulating fluid is called hemolymph.
Ostia are pores in the heart, important for circulatory function.
The circulating fluid is called blood.
The circulating fluid remains in vessels as it moves throughout the organism.
Is the more efficient type of circulatory system.

C)An open circulatory system opens into the heart whereas the closed circulatory system does not. D)An open circulatory system drains into the mantle cavity whereas a closed circulatory system drains into the hemolymph.

- 19. The diagram below is a schematic representation of the circulatory system. In other words, it is not meant to be a realistic drawing of body parts, but only to show the basic scheme of the system – the relationships among its parts and the sequence of events that occur in the system. The circulation of blood is vital to the process of respiration, since the blood carries fresh oxygen to the cells of the body and returns carbon dioxide to the lungs to be expelled. As you have learned, arteries are the blood vessels that carry blood away from the heart. Which blood vessels in the diagram are arteries? The arrows indicate the blood vessels 2 and 3 carry blood away from the heart, so they are arteries. Blood vessels 1 and 4, which return blood to the heart, are veins. Study the diagram below and then answer the questions that follow. Heart Body cells Lungs Key: Oxygen-rich blood Carbon dioxide-rich blood A. Refer to the diagram. Blood that is rich in oxygen is found in which two of the…arrow_forwardList down the functions of the Circulatory System in animals.arrow_forwardSome animals use diffusion instead of a circulatory system.
