PUMP IT!

1.The water inside the jar

ANSWER:

It represents the blood. Our blood is a speciliazed body fluid that has four main components:

  1. Plasma
  2. Red Blood Cells
  3. White Blood Cells
  4. Platelets

The key functions of our blood are:

  • It transport nutrients and oxygen to our tissues and blood
  • It carries cells and antibodies that fights any kinds of infection
  • It aids in formation of blood clots to avoid excessive bleeding
  • It brings waste products to our liver and kidney where it filters and clean the blood
  • It regulates our body temperature

2. The human heart and the heart pump model

ANSWER:

The activity shows the main function of the heart. The human heart is represented by the jar, the water acts as the blood while the straws acts as the vein and the artery. The pan represents the other body parts where the blood is distributed. The balloon pumps the water into the straw and into the jar then to the pan. In a similar manner, the blood is pumped into the veins then into the heart. The heart pumps the blood through the arteries then to any parts of the body.

3. The heart as a pump

ANSWER:

The heart rhythm or contraction causes the blood to continuously flow to the heart, lungs and body to distribute oxygen and nutrients to the body cells.

4. The model if the straw is blocked

ANSWER:

No. The main purpose of the straw is similar to the vein and artery in the heart. As the blood circulates passing through the veins and into the heart, it pumps blood outside from the heart passing through the artery. If the vein or the artery is blocked, it cannot perform its function, thus a blood clot or cardiac arrest might occur.
