18 Questions
What is the main purpose of the two circuits in the transport system described?
To pick up oxygen from the environment and deliver it to tissues
What is the difference in pressure between the capillaries in the gills and the capillaries in the body tissues?
The pressure is lower in the gills capillaries
What is the main advantage of a closed circulatory system compared to an open circulatory system?
It allows for greater control over blood flow and distribution
How does the single circulatory system of fish limit the delivery of oxygen to body cells?
It causes the blood to flow too slowly through the body
What is the main function of the heart in the single circulatory system of fish?
To pump blood to the gills and then to the body tissues
How does the single circulatory system of fish limit the removal of waste products from the body?
It prevents the blood from passing through the body tissues quickly enough
Why can blood flow more quickly in systemic circulation compared to pulmonary circulation?
Higher pressure in systemic circulation
In a closed circulatory system, where is blood always contained as it flows to the heart?
Blood vessels
What is the advantage of a closed circulatory system over an open circulatory system?
Higher pressure for rapid blood movement
What is the role of tissue fluid in a closed circulatory system?
Bathing tissues and cells
What supplies energy for activity and warmth in mammals?
Food
Which statement best describes the function of respiration in mammals?
Releasing energy from food using oxygen
What is one advantage of the double circulatory system over a single circulatory system?
Delivers oxygen and nutrients to body tissues faster
Which circulation carries blood to the lungs to pick up oxygen?
Pulmonary circulation
What happens in the lungs during the process of oxygen diffusion into the blood?
Blood passes through capillaries
Why should blood pressure not be too high during pulmonary circulation in the double circulatory system?
To prevent damage to lung capillaries
What is an essential feature of the double circulatory system that allows for efficient delivery of oxygen and nutrients to body tissues?
Passing blood through the heart twice for each circuit
Which part of the circulatory system ensures that blood moves more quickly to deliver oxygen and nutrients efficiently?
Heart
