1.2.2 Water in the Cardiovascular System

• What is another name for the cardiovascular system?

  Circulatory system
• The liquid portion of blood is called plasma
• Match the component of the cardiovascular system with its role:

  Heart ↔️ Pumps blood

  Blood Vessels ↔️ Transport blood

  Blood ↔️ Carries oxygen and nutrients

  Plasma ↔️ Maintains blood volume
• Arrange the following roles of water in the cardiovascular system in order of importance:

  1️⃣ Maintaining blood volume

  2️⃣ Enabling the transport of substances

  3️⃣ Regulating blood pressure
• Water is essential for maintaining blood volume and pressure in the cardiovascular system.
• What ensures efficient blood circulation in the cardiovascular system?

  The heart
• Blood vessels transport blood and carry dissolved oxygen, nutrients, and waste
• What maintains blood volume and blood pressure in the cardiovascular system?

  Plasma
• Water is crucial for maintaining blood volume and serving as a solvent in the blood.
• Arrange the following substances transported by water in blood plasma from most to least abundant:

  1️⃣ Oxygen

  2️⃣ Nutrients

  3️⃣ Hormones

  4️⃣ Waste products

  5️⃣ Electrolytes
• Waste products such as urea and carbon dioxide are dissolved in plasma and transported to the lungs and kidneys
• Which electrolytes are essential for maintaining osmotic balance and nerve function?

  Sodium, potassium, chloride
• Blood plasma is primarily composed of water, making it the largest component of blood volume.
• Dehydration can lead to reduced blood volume and lower blood pressure
• What happens to blood volume and blood pressure during normal hydration?

  Both are adequate
• Blood plasma is primarily composed of water
• Dehydration can lead to reduced blood volume and lower blood pressure.
• Match the condition with its effects on blood volume and pressure:

  Normal ↔️ Adequate blood volume, optimal pressure

  Dehydration ↔️ Decreased blood volume, lower pressure
• The cardiovascular system transports oxygen, nutrients, hormones, and waste
• Match the cardiovascular component with its role and the importance of water:

  Heart ↔️ Pumps blood, ensures efficient circulation

  Blood Vessels ↔️ Transport blood, carries dissolved substances

  Blood ↔️ Carries substances, acts as a solvent

  Plasma ↔️ Liquid portion of blood, maintains volume
• Water is a key solvent in blood plasma, enabling the dissolution and transport of substances
• Oxygen is primarily transported in blood plasma unbound.

  False
• Match the substance in blood plasma with its importance and form:

  Oxygen ↔️ Respiration, dissolved

  Glucose ↔️ Energy source, dissolved

  Hormones ↔️ Regulation, transported

  Urea ↔️ Waste removal, dissolved

  Electrolytes ↔️ Osmotic balance, dissolved
• Water plays a crucial role in thermoregulation within the cardiovascular system by facilitating heat loss through sweating and vasodilation
• Steps in the process of thermoregulation within the cardiovascular system:

  1️⃣ Water absorbs heat from tissues

  2️⃣ Heat circulates via blood

  3️⃣ Vasodilation increases blood flow

  4️⃣ Sweat evaporates from skin
