    • The heart is the central pumping organ of the circulatory system.

      True
    • What is the function of the heart in the circulatory system?
      Pumps blood
    • The heart propels blood through blood vessels.

      True
    • Arteries carry blood away from the heart to deliver oxygen and nutrients
    • Match the blood vessel with its characteristic:
      Arteries ↔️ Thick, muscular walls
      Veins ↔️ Thinner walls with valves
      Capillaries ↔️ Dense network for exchange
    • Match the type of blood vessel with its function:
      Arteries ↔️ Carry blood away from the heart
      Veins ↔️ Carry blood towards the heart
      Capillaries ↔️ Exchange substances with tissues
    • Capillaries facilitate the exchange of substances between blood and body tissues.

      True
    • Blood contains cells and plasma
    • Veins have valves to prevent backflow of blood.

      True
    • Arteries carry blood away from the heart.
    • Veins have thicker walls than arteries.
      False
    • Match the heart chamber with its function:
      Right Atrium ↔️ Receives deoxygenated blood
      Left Ventricle ↔️ Pumps oxygenated blood
      Right Ventricle ↔️ Pumps blood to lungs
    • In systemic circulation, blood flows from the left ventricle to the body tissues.
    • The continuous circulation of blood through the heart and body ensures the efficient transport of essential substances
    • What is the primary function of the circulatory system?
      Transport substances
    • What does blood carry to cells in the body?
      Oxygen and nutrients
    • Which type of blood vessel carries blood away from the heart?
      Arteries
    • Order the functions of the circulatory system:
      1️⃣ Transport oxygen to cells
      2️⃣ Transport nutrients to cells
      3️⃣ Transport hormones to regulate processes
      4️⃣ Transport waste products away from cells
    • Arteries have thick, muscular walls to withstand high pressure from blood pumped by the heart.
    • What is the central organ of the circulatory system?
      Heart
    • Arrange the blood vessels in order of blood flow away from the heart
      1️⃣ Arteries
      2️⃣ Capillaries
      3️⃣ Veins
    • Capillaries maximize surface area for substance exchange with body tissues.
    • White blood cells provide immune defense against infection.

      True
    • The circulatory system has two main pathways for blood circulation: pulmonary and systemic.

      True
    • In the lungs, blood picks up oxygen and releases carbon dioxide.

      True
    • In the body tissues, blood delivers oxygen and nutrients and collects waste products
    • Veins carry blood towards the heart.

      True
    • What are the three main components of the circulatory system?
      Heart, blood vessels, blood
    • White blood cells defend against infection in the circulatory system.
      True
    • Heart valves ensure blood flows in a one-way direction through the chambers.
    • Arrange the steps of pulmonary circulation in order:
      1️⃣ Blood flows from right ventricle
      2️⃣ Blood travels to lungs
      3️⃣ Oxygen is absorbed, carbon dioxide released
      4️⃣ Oxygenated blood returns to left atrium
    • Oxygenated blood returns to the left atrium
    • Regular physical activity improves cardiovascular fitness.
      True
    • Match the blood vessel type with its function:
      Arteries ↔️ Carry blood away from the heart
      Veins ↔️ Carry blood towards the heart
      Capillaries ↔️ Facilitate substance exchange
    • Arteries carry blood away from the heart to deliver oxygen and nutrients.

      True
    • Match the heart chamber with its function:
      Right Atrium ↔️ Receives deoxygenated blood
      Right Ventricle ↔️ Pumps blood to the lungs
      Left Atrium ↔️ Receives oxygenated blood
      Left Ventricle ↔️ Pumps blood to the body
    • What ensures the efficient circulation of essential substances throughout the body?
      Blood vessels and heart
    • The heart acts as a pump to circulate blood throughout the body.
      True
    • Where are red blood cells produced in the body?
      Bone marrow
    • A healthy circulatory system is essential for overall well-being.
