Circulatory System Flashcards
Is the primary method used to transport nutrients and gases throughout the body. It is made up of blood, blood vessels and the heart.
Circulatory System
What are the two main types of circulatory system?
Open and Closed Circulatory System
In this circulatory system, blood vessels transport all fluids into a cavity.
Open Circulatory System
Arthropods– including insects, crustaceans, and most mollusks– have this type of circulatory system.
Open Circulatory System
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.
Open Circulatory System
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.
Hemocoel
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.
Hemolymph
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 _____.
Ostia
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.
Closed Circulatory System
All vertebrate animals have this type of circulatory system.
Closed Circulatory System
What are the 3 components of the circulatory system?
Heart, Blood Vessels, Blood
Pumps blood through the blood vessels of the circulatory system.
Heart
What are the 3 blood vessels?
Arteries, Veins, Capillaries
Blood vessels that carry blood away from the heart to the other parts of the body.
Arteries
Blood vessels that carry blood from the body back to the heart.
Veins
Tiny tubes that carry blood from the arteries to the body’s cells, and then back to the veins.
Capillaries
What are the 4 components of blood?
RBC, WBS, Plasma, Platelets
55% of the blood is composed of?
Plasma
> 1% of the blood is composed these two components.
WBC, Platelets
45% of the blood is composed of?
RBC
Carries oxygen from lungs to all cells of the body; carries carbon dioxide away from cells.
RBC
Are the cells of the immune system that are involved in protecting the body against infection and foreign invaders.
WBC
Liquid portion of the blood composed mostly of water. It transports nutrients, hormones, and proteins to the parts of the body.
Plasma
For blood clotting and blood coagulation.
Platelets
What are the 2 types of circulation?
Pulmonary and Systematic Circulation
This circulation carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated blood back to the heart.
Pulmonary Circulation
This circulation carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.
Systematic Circulation
This circulatory system has no arteries to increase BP, therefore, has more blood at low pressure.
Open Circulatory System
This circulatory system requires less energy for distributing blood.
Open Circulatory System
This circulatory system carries blood at high pressure and delivers blood quickly.
Closed Circulatory System
This circulatory system is suitable for animals with fast metabolism.
Closed Circulatory System
Fish are vertebrates that have a ______ loop
circulatory system.
Single loop
Mammals that have a double loop circulatory
system.
Double loop
In a ______ loop system, blood only passes through the the heart one type on each circuit through the body.
Single loop
The evolution of the ______ circulatory loop allows more oxygen to be delivered to their bodies.
Double (second) loop
In the circulatory loop that connects an amphibian’s heart to its lungs there are blood vessels called?
Pulmonary Veins
Are the vessels that carry the oxygen-rich blood from the amphibian’s lungs directly back to its heart.
Pulmonary Veins
Do sponges have a real circulatory system?
No
Sponges have ___________ cells over the surface of their bodies, these are cells that have tails that wiggle.
Flagellated
They do not have a circulatory system simply because it is not needed.
Cnidarians
They do not obtain a circulatory system and are able to transfer the oxygen and the necessary nutrients for themselves by diffusion.
Nematodes
Do annelids have an open or closed circulatory system?
Closed
Do mollusks have an open or closed circulatory system?
Open
Do anthropods have an open or closed circulatory system?
Open
Do echinoderms have an open or closed circulatory system?
Open
