Test: Circulatory System - Question 3

In mammals, where does deoxygenated blood first enter the heart?

Detailed Solution for Test: Circulatory System - Question 3
Deoxygenated blood from the body enters the right atrium of the heart before being pumped to the lungs.
Test: Circulatory System - Question 4
Which type of circulation involves the heart pumping oxygenated blood to the rest of the body?
Detailed Solution for Test: Circulatory System - Question 4
Systemic circulation is the process where oxygenated blood is pumped from the left side of the heart to the rest of the body.
Test: Circulatory System - Question 5
What is the primary advantage of the double circulatory system in mammals?
Detailed Solution for Test: Circulatory System - Question 5
The double circulatory system ensures that blood passes through the heart twice in one complete circuit, allowing for a pressure boost and efficient delivery of oxygen and nutrients.
Test: Circulatory System - Question 6
What happens to blood pressure as blood moves through the capillaries in the lungs?
Detailed Solution for Test: Circulatory System - Question 6
Blood pressure decreases significantly as blood travels through the capillaries in the lungs, necessitating a pressure boost when the blood returns to the heart.
Test: Circulatory System - Question 7
Which side of the heart receives oxygenated blood from the lungs?
Detailed Solution for Test: Circulatory System - Question 7
The left side of the heart receives oxygenated blood from the lungs before pumping it to the rest of the body.
Test: Circulatory System - Question 8
During which part of the circulatory process does blood experience a pressure drop?
Detailed Solution for Test: Circulatory System - Question 8
Blood experiences a pressure drop as it moves through the capillaries in the lungs during pulmonary circulation.
Test: Circulatory System - Question 9
How does the heart ensure efficient blood flow in mammals?
Detailed Solution for Test: Circulatory System - Question 9
The heart uses valves to ensure a one-way flow of blood and prevent backflow, contributing to efficient blood circulation.
Test: Circulatory System - Question 10
Why is it beneficial for mammals to have a double circulatory system compared to a single circulatory system?
Detailed Solution for Test: Circulatory System - Question 10
The double circulatory system in mammals is beneficial because it allows for more efficient delivery of oxygen and nutrients by providing a pressure boost to the blood after it has traveled through the lungs.
