What are the upper chambers of the heart?
Atria
What is the purpose of valves in the heart?
To separate the atria from the ventricles
What are the lower chambers of the heart?
Ventricles
What is the main function of the heart?
To pump blood throughout the body
What is the purpose of the muscular walls in the heart?
To pump blood through the body
What separates the atria from the ventricles?
Valves
What are the two upper chambers of the heart?
Atria
What is the function of the valves in the heart?
To separate the atria from the ventricles
What are the two lower chambers of the heart?
Ventricles
The heart has three atria and two ventricles.
False
Valves are responsible for pumping blood in the heart.
False
The atria are the lower chambers of the heart.
False
The muscular walls of the heart are responsible for separating the atria from the ventricles.
False
The heart has two upper chambers and three lower chambers.
False
The heart chambers include two atria, the two upper chambers, and two lower chambers called the ______
ventricles
Valves separate the atria from the ______
ventricles
Muscular walls coordinate contractions of ______ muscle pump of blood
cardiac
The two upper chambers of the heart are called ______
atria
The muscular walls coordinate the contractions of cardiac muscle to pump ______
blood
What is the function of the right atrium?
To receive blood from the body and pump it into the ventricles
What is the purpose of the atria?
To receive and pump blood into the ventricles
What is the difference between the left and right atria?
The left atrium receives blood from the lungs, and the right atrium receives blood from the body
What happens when the atria contract?
Blood is pumped from the atria into the ventricles
What is the relation between the atria and ventricles?
The atria pump blood into the ventricles
The heart has three left atria and two right atria
False
The atria receive blood from the body and lungs when they are contracted
False
The right atrium receives blood from the lungs
False
The left atrium pumps blood into the ventricles when contracted
False
The heart's chambers include two ventricles at the top and two atria at the base
False
Match the atria with their functions:
Right atrium = Receives blood from the body Left atrium = Receives blood from the body
Match the parts of the heart with their locations:
Base = Bottom of the heart Apex = Bottom of the heart
Match the atria with the chambers they pump blood into:
Right atrium = Left ventricle Left atrium = Left ventricle
Match the atria with their sources of blood:
Right atrium = Lungs Left atrium = Body
Match the terms with their definitions:
Atria = Lower chambers of the heart Atrium = Plural form of atria
