The circulatory system is also known as the ______.

The circulatory system moves all substances, such as ______, to or from cells.

It is the body’s “______”

______: the pump that keeps blood moving trough blood vessels

______: thick liquid that transports nutrients and wastes

¡  ______: makes up blood, mostly water

¡  ______: give the blood its thickness

¡  ______: transports oxygen

¡  ______: helps fight infections

______: transport blood throughout the body

______: The main organ of the circulatory system, pumps the blood throughout the body

55% of blood is ______- which is made up of 90% water, 10% nutrients (minerals, proteins, cholesterol, etc.)

Plasma ______; it’s why blood is liquid and runny

______give the blood its thickness, and helps in blood clotting.

Red blood cells carry the ______

¡  They have ______that can BIND to the oxygen and then carry it.

White blood cells are types of immune cells that ______.

Blood Vessels ______

¡  VESSELS are the VEHICLES for blood to transfer

The respiratory system brings in oxygen to the body and releases carbon dioxide

¡  Then, that oxygen enters and the carbon dioxide exits the ______and travels through the body through the blood

¡  The respiratory and circulatory systems show us that ______, BUT WORK TOGETHER for the benefit of the body

Blood is always ______, even if veins may look blue

¡  Sometimes blood is more red than at other times, and can appear kind of purple

¡  ______blood has, which it gets from the lungs the brighter red the color

INDEPENDENT PRACTICE

PART 1: Fill-in-the-blank

1.  The ______system moves all substances, such as ______and nutrients, to or from cells where they are needed or produced, responding to changing demands.

2.  Oxygen inhaled into the body by the ______system is transported in the blood by the circulatory system.

3.  ______is the thick liquid that transports nutrients and wastes throughout the body.

4.  ______blood cells transports oxygen while ______blood cells help fight infections.

5.  The circulatory system is the body’s “delivery service” as it ______oxygen and nutrients to cells throughout the body.

6.  The respiratory and circulatory systems working together to take in oxygen and transport it throughout the body shows us body systems are not ______but work together.

7.  The main organ of the circulatory system is the ______, which is the pump that keeps blood moving trough blood vessels.

8.  All the body’s organs systems work together to ensure you are alive and well in a process known as ______.

PART 2: True/False. For each statement that is false, RE-WRITE THE ENTIRE STATEMENT so that it is true.

9.  ______Oxygen enters and the carbon dioxide exits the circulatory system and travels through the body through the blood.

10.  ______Platelets are the vehicles that transport blood throughout the body.

11.  ______White blood cells are types of immune cells that fight infectious disease.

12.  ______Plasma gives the blood its thickness and begins to heal areas that are cut.

13.  ______The heart is the main organ of the circulatory system and pumps blood throughout the body.

14.  ______Blood is the thick liquid that transports nutrients and wastes throughout the body

PART 3: Multiple-choice. Use MCS to answer the following choices.

15.  What is the circulatory system?

  1. The body’s breathing system
  2. The body’s system of nerves
  3. The body’s food processing system
  4. The body’s blood-transporting system

16.  Why is oxygen important to blood and to the cells?

  1. Oxygen helps the blood to clot
  2. Oxygen brings food to the cells
  3. Oxygen is necessary for cell growth and energy
  4. Oxygen is not important-carbon dioxide is the most important substance to the body

17.  Why is blood that flows from the lungs to the heart bright red rather than dark red?

  1. Oxygen makes it red
  2. Carbon dioxide makes it red
  3. Gastric juices produces the red color of the blood
  4. The lungs add a pigment (dye) to blood as it flows through them

18.  What happens to blood when it is pumped into the thin-walled capillaries and alveoli of the lungs?

  1. Platelets are exchanged for plasma
  2. Carbon dioxide is replaced with oxygen
  3. Blood fills the lungs and causes coughing
  4. Nothing – the lungs are just a place blood goes through on its way back to the heart

19.  Why does blood turn dark red as it circulates through the body?

  1. It starts to clot
  2. It gets old and dirty flowing through the body
  3. The oxygen in it is replaced with carbon dioxide
  4. The blood never changes colors
