Identifying the parts of the

circulatory system

Hi kids! I’m Blake. I’m ablood droplet. Small as I am,but in this lesson you willfind out how important I amin keeping you and everyonealive. Not only me of course

TASKANALYSIS

Describing each part of the

circulatory system

Giving ways on how to keep the

circulatory system healthy.

Now kids try to identify the

Whoa! I bet you’veguessed intelligently.Now let us try tounderstand more about meand my friends in the

GUIDE CARD

Circulatory System is the transportsystem of the body. Its main function isto transport nutrients and oxygen to thedifferent parts of the body andsimultaneously collects waste products andcarbon dioxide from the cells.

The Circulatory system also known asCardiovascular System has three mainparts. These are the heart, the bloodvessels and the blood.

Well now you know my friends in the Circulatory System. Let us mug up more about them.

Hello there! I’m the heart areyou ready to know more about me? Well let’s begin!

The HeartThe Heart is a hollow

muscular organ locatedbetween the lungs slightlytilted at left side of thechest. Its main function isto pump blood that is why

Did you know that the heart is just about the size ofyour fist? It has four chambers where the blood flows. Thesechambers are divided into two pairs. The left chambers pumpthe oxygen rich blood from the lungs while the rightchambers pumps the deoxygenated blood from the different

Now kids let uslook inside theheart and see whatwe’ll find out!

AORTA- The largest artery in the body

LEFT ATRIUM- It isthe upper part ofthe left chamberswhich catches theoxygenated blood

PULMONARY VEIN- It is where the oxygenated blood from the

SUPERIOR VENA CAVA-It is where the deoxygenated blood from the upper partof the body flows

PULMONARY ARTERY- It is where the deoxygenated blood flow from the heart

FIST

INFERIOR VENA CAVA-It is where thedeoxygenated bloodfrom the lower partof the body flows

RIGHT VENTRICLE-It is the thickwalled lower partof the rightchambers which

RIGHT ATRIUM- Itis the upper partof the rightchambers whichcatches thedeoxygenated

LEFT VENTRICLE- Itis the thick walledlower part of theleft chambers whichpushes the blood to

SEPTUM- It is amuscular wall whichseparates the leftfrom the rightchambers. It

VALVES- It actslike doors whichprevents the bloodfrom flowing back.It produces the

PERICARDIAL SAC- Itis a membrane thatprotects the heart

This time I’ll introduceto you my other friendBlood Vessel. Are youready? Let’s hit the

ARTERY- It carries the blood away from the heart.The fresh oxygenated bloodpasses through this blood vessel. Its thick walls

THE BLOOD VESSELS

The Blood Vessels are tube-likestructures which are interconnected witheach other forming a complex network in thebody. It is where the blood flows throughoutthe body. They differ in size and thickness.There are three types of blood vesselsnamely the artery, vein and capillary.CAPILLARY- It is the

thinnest among the blood vessels. It is where the exchange of oxygen and nutrients to the cells andcarbon dioxide and waste

VEIN- It carries the bloodto the heart. The deoxygenated blood passes through this blood vessel.It has thinner walls than

This is how blood lookslike inside the bloodvessel. It “swims” in afluid called plasma.

Did you know…

that about 75% of thetotal composition of ourblood is plasma? It’s likeyou swimming in the vastocean! That the average volume ofblood of an adult man is 6liters.That women’s blood volumeincreases during

Now it’s my turn to shine!

I’d like you to know more aboutme.

THE BLOODThe blood is the red fluid inside our body which flows out when

our skin is cut. It is also known as “the river of life” because ofits work which is to transport nutrients and oxygen to the cells andcollects waste materials and carbon dioxide from the cells. The bloodhas three types: the red blood cell, the white blood cell and theplatelets.

Now that you already met my friends in thecirculatory system, let’s find out if youremembered them well. Let’s do some tasks.Identify the pictures and write your answer in

Each of the blood cells have special functionsto do.

The red blood cells (RBC)/erythrocytes arethe “transporters”. Their function is totransport nutrients and oxygen to thecells and collect waste products andcarbon dioxide from the cells.The white blood cells (WBC)/Leukocytes arethe “Soldiers/Defenders” of the body. Theyfight infectious bacteria and viruses andilluminate them from the body.

Here are some waysto keep ourcirculatory systemhealthy. Just dothese and you won’t

1. Exercise regularly.Remember that walkingis the best form ofexercise for thecirculatory system.

2. Eat healthy andnutritious food. Avoidfatty and saltydishes.

3. Drink 8 to 10glasses of water everyday to avoiddehydration.

5. Have a regularcheck up with yourdoctor.

Gulp!!!

4. Avoid too muchstress and fatigue.

6. Do not drinkalcoholic beverages.

7. Do not smoke.

8. Don’t do drugs.
