Which vessel returns deoxygenated blood to the right atrium?
Press to flip
Deoxygenated blood returns to the right atrium via the vena cava.
Describe the path deoxygenated blood takes in the pulmonary circuit.
Deoxygenated blood leaves the right ventricle via the pulmonary artery, goes to the lungs for oxygenation, and returns to the left atrium via the pulmonary veins.
What are the two separate circuits involved in double circulation?
The two circuits are the pulmonary circuit and the systemic circuit.
What advantage does higher blood pressure in the systemic circuit provide?
Higher blood pressure in the systemic circuit ensures that oxygenated blood can reach all parts of the body effectively.
What is the main function of the systemic circuit?
The main function of the systemic circuit is to deliver oxygenated blood from the left ventricle to the entire body and return deoxygenated blood to the right atrium.
Why does the right ventricle have a thinner wall compared to the left ventricle?
The right ventricle has a thinner wall because it only needs to pump blood a short distance to the lungs (pulmonary circuit), unlike the left ventricle, which pumps blood throughout the entire body (systemic circuit).
Which side of the heart is responsible for the pulmonary circuit?
The right side of the heart is responsible for pumping deoxygenated blood to the lungs in the pulmonary circuit.
How does double circulation facilitate higher blood pressure?
Double circulation allows the heart to pump oxygenated and deoxygenated blood separately, enabling higher blood pressure to be maintained in the systemic circuit, ensuring efficient delivery of oxygenated blood to all parts of the body.
In double circulation, how is the work of the heart divided?
In double circulation, the heart acts as two pumps: the right side pumps deoxygenated blood to the lungs (pulmonary circuit), while the left side pumps oxygenated blood to the rest of the body (systemic circuit).
What are the benefits of separating oxygenated and deoxygenated blood in double circulation?
Separating oxygenated and deoxygenated blood in double circulation is more efficient and allows for higher blood pressure, which ensures that oxygen and nutrients are effectively delivered to all body tissues.
What is double circulation in the circulatory system?
Double circulation means that blood passes through the heart twice during one complete circuit: once to get oxygenated in the lungs and once to deliver oxygen to the rest of the body.
Through which vessel does oxygenated blood leave the left ventricle?
Oxygenated blood leaves the left ventricle via the aorta.
Which side of the heart handles the systemic circuit?
The left side of the heart handles pumping oxygenated blood to the body in the systemic circuit.
Why does the left ventricle have a thicker wall than the right ventricle?
The left ventricle has a thicker wall because it needs to generate higher blood pressure to pump oxygenated blood throughout the entire body, which involves a longer distance compared to the pulmonary circuit.
What is the primary function of the pulmonary circuit?
The primary function of the pulmonary circuit is to deliver deoxygenated blood from the right ventricle to the lungs for oxygenation and then return oxygenated blood to the left atrium.
