Single vs double circulation

• Why is single circulation effective for fish?

  They are small and active enough
• How does blood flow in single circulation?

  Heart to gills to body to heart
• What is the process of single circulation in fish?

  • Blood flows from the heart
  • Moves to the gills to pick up oxygen
  • Travels directly to the body
  • Returns to the heart
• What occurs in pulmonary circulation?

  Blood flows from the heart to the lungs
• What does double circulation mean?

  Blood passes through the heart twice
• What is the function of systemic circulation?

  To deliver oxygen to cells in the body
• Which type of organisms have double circulation?

  Mammals
• How many times does blood go through the heart in double circulation?

  Twice
• What are the main components of the circulatory system shown in the image?

  Artery, Vein, Heart (Ventricle and Atrium), Pulmonary circuit, Systemic circuit
• What is the purpose of pulmonary circulation?

  To pick up oxygen and release carbon dioxide
• What are the key differences between the gill capillaries and the lung capillaries shown in the image?

  • Gill capillaries are found in fish, lung capillaries are found in mammals
  • Gill capillaries oxygenate blood, lung capillaries exchange gases (O2 and CO2)
  • Gill capillaries are part of the gill circuit, lung capillaries are part of the pulmonary circuit
  • Gill capillaries are located near the gills, lung capillaries are located in the alveoli of the lungs
• What are the two distinct circuits in double circulation?

  1. Pulmonary circulation
  2. Systemic circulation
• What is the role of the ventricle in single circulation?

  Pumps blood directly to the gills
• What happens in systemic circulation?

  Oxygenated blood flows from the heart to the body
• How does single circulation function in fish?

  One ventricle pumps blood in a single loop
• If a person has a blockage in their systemic capillaries, how would this affect blood flow in their body?

  It would reduce blood flow to the body's tissues and organs
• How many atria are present in double circulation?

  Two atria
• What is the main difference between single and double circulation?

  Single has one loop; double has two circuits
• What is the purpose of the heart's ventricle and atrium shown in the image?

  The ventricle pumps blood out of the heart, the atrium receives blood into the heart
• What type of circulation do fish have?

  Single circulation
• What are the main components of the circulatory system shown in the image?

  Artery, Vein, Heart (Ventricle and Atrium), Pulmonary circuit, Systemic circuit
• Why is double circulation more efficient for larger organisms?

  It allows for separate oxygenation and body circulation
• What is the purpose of the pulmonary circuit shown in the image?

  To transport deoxygenated blood from the heart to the lungs and oxygenated blood back to the heart
• How do the gill capillaries and lung capillaries differ in their function and location?

  • Gill capillaries oxygenate blood in fish, while lung capillaries exchange gases (O2 and CO2) in mammals
  • Gill capillaries are located near the gills, while lung capillaries are located in the alveoli of the lungs
• What are the key differences between the systemic capillaries and the pulmonary capillaries shown in the image?

  • Systemic capillaries transport oxygenated blood from the heart to the body's tissues
  • Pulmonary capillaries transport deoxygenated blood from the heart to the lungs
  • Systemic capillaries are part of the systemic circuit, pulmonary capillaries are part of the pulmonary circuit
  • Systemic capillaries are located throughout the body, pulmonary capillaries are located in the lungs
• What are the key differences between the systemic capillaries and the pulmonary capillaries shown in the image?

  • Systemic capillaries transport oxygenated blood from the heart to the body's tissues
  • Pulmonary capillaries transport deoxygenated blood from the heart to the lungs
  • Systemic capillaries are part of the systemic circuit, pulmonary capillaries are part of the pulmonary circuit
  • Systemic capillaries are located throughout the body, pulmonary capillaries are located in the lungs
• What is the purpose of the pulmonary circuit shown in the image?

  To transport deoxygenated blood from the heart to the lungs and oxygenated blood back to the heart
• How does the structure of double circulation support larger, active organisms?

  It enhances oxygen delivery and nutrient distribution
• What is the purpose of the heart's ventricle and atrium shown in the image?

  The ventricle pumps blood out of the heart, the atrium receives blood into the heart
• If a person has a blockage in their systemic capillaries, how would this affect blood flow in their body?

  It would reduce blood flow to the body's tissues and organs
• How do the gill capillaries and lung capillaries differ in their function and location?

  • Gill capillaries oxygenate blood in fish, while lung capillaries exchange gases (O2 and CO2) in mammals
  • Gill capillaries are located near the gills, while lung capillaries are located in the alveoli of the lungs
• If a person has a blockage in their systemic capillaries, how would this affect blood flow in their body?

  It would reduce blood flow to the body's tissues and organs
• How does double circulation achieve faster oxygen delivery to the body?

  Blood is pumped twice by the heart
• What type of circulation is characterized by blood traveling at low pressure after passing through gills?

  Single circulation
• How does the pressure of blood in single circulation compare to that in double circulation?

  Single circulation has lower pressure than double
• What is a key feature of double circulation?

  Maintains high blood pressure
• What are the key differences between the systemic capillaries and the pulmonary capillaries shown in the image?

  • Systemic capillaries transport oxygenated blood from the heart to the body's tissues
  • Pulmonary capillaries transport deoxygenated blood from the heart to the lungs
  • Systemic capillaries are part of the systemic circuit, pulmonary capillaries are part of the pulmonary circuit
  • Systemic capillaries are located throughout the body, pulmonary capillaries are located in the lungs
• What are the main differences between single and double circulatory systems?

  • Single circulation:
  • Blood travels at low pressure
  • Less efficient oxygen delivery
  • Double circulation:
  • Blood maintains high pressure
  • Blood is pumped twice by the heart
  • Faster oxygen delivery to the body
• What are the key differences between the gill capillaries and the lung capillaries shown in the image?

  • Gill capillaries are found in fish, lung capillaries are found in mammals
  • Gill capillaries oxygenate blood, lung capillaries exchange gases (O2 and CO2)
  • Gill capillaries are part of the gill circuit, lung capillaries are part of the pulmonary circuit
  • Gill capillaries are located near the gills, lung capillaries are located in the alveoli of the lungs
