25 Questions
What is the primary function of the blood in the human body?
to carry nutrients, oxygen, and waste products to and from the cells
What are the two main components of the cardiovascular system?
heart and blood vessels
What is transported by the blood to the cells?
nutrients and oxygen
What is transported by the blood away from the cells?
waste products
What are the four chambers of the heart?
right atrium, left atrium, right ventricle, and left ventricle
What is the ultimate goal of the cardiovascular system?
to maintain cellular health
How do the atria differ from the ventricles in terms of size?
The atria are smaller than the ventricles.
What is a characteristic of the atria's walls compared to the ventricles?
Thinner and less muscular
Which chambers of the heart receive blood?
Atria
Which chambers of the heart pump blood out of the heart?
Ventricles
What is the primary function of the right ventricle in the heart?
To pump blood into the pulmonary trunk
What is the connection between the ventricles and the arteries in the heart?
The ventricles are connected to the arteries that carry blood away from the heart
Into which vessel does the right ventricle pump blood?
The pulmonary trunk
What is the direction of blood flow pumped by the right ventricle?
Away from the heart
What is the role of the ventricles in the heart's circulation?
To pump blood into the arteries that carry blood away from the heart
What is the function of the tricuspid valve in the heart?
The tricuspid valve regulates blood flow between the right atrium and right ventricle.
What is the main difference between the pulmonary valve and the aortic valve?
The pulmonary valve controls blood flow from the right ventricle into pulmonary arteries, while the aortic valve controls blood flow from the left ventricle into the aorta.
What is the role of AV valves in the heart?
AV valves lie between the atria and the ventricles and regulate blood flow between them.
Which valve controls blood flow from the left atrium into the left ventricle?
The mitral valve controls blood flow from the left atrium into the left ventricle.
How many valves regulate blood flow through the heart?
Four valves regulate blood flow through the heart.
What is the location of Purkinje fibers in the heart?
In the walls of ventricles, from the ends of the bundle branches
How many coronary arteries arise from the aorta?
2
What is the origin of the coronary arteries?
The aorta
Where do the Purkinje fibers originate from?
The ends of the bundle branches
What part of the heart do the Purkinje fibers pass through?
The ventricular walls
