This is a place where our grade 5 & 6 students will collect, share, & build what they know/learn about the human body.
(We'll show our learning by telling a story about a red blood cell's journey. Students, see Nov. 27th on our assignment calendar

Cardiovascular System

This little video might help


How does the cardiovascular system work?

Our cardiovascular system works by moving blood through your heart and around your body.

Where is your heart located?

Our heart is located in the middle of your rib cage, but slightly to the left.

What are the parts of the heart called?

The parts of our heart are: pulmonary artery, right atrium, right ventricle, aorta, left atrium, and left ventricle.

What is blood?, What does blood do?, What is blood made up of?

Blood is made up of red blood cells, white blood cells,platelets, and plasma.
Red blood cells carry oxygen throughout the body.
White blood cells help fight infections.
Platelets help clot blood.
And plasma makes the blood sticky so that you dont bleed to death.

How many times a day do we breath?

An average human breathes 18, 280 times a day.

What are small arteries called?

Small arteries are called arterioles.

What are the four chambers of the heart called?

The four chambers of your heart are called:
‍The right and left atrium, and the right and left ventricle

How many times does your heart beat in a minute? in a day? in a year? in a lifetime?

The average heart beats about 80 times per minute, about 200,000 times a day, about 38 million times a year, and about 3 billion times in lifetime.

What does the cardiovascular system do?

Our cardiovascular system is a major body system and it makes sure your body has the right amount of oxygen and blood.

what do venules do?

Venules eventually join to form veins.

How big is the cardiovascular system?

It fills about 20% of your body

What other organs are in our cardiovascular system, besides our heart?


What are the parts of the cardiovascular system?

Can we live without some organs of the cardiovascular system?

Yes unless the heart is removed

What are arteries, veins, arterioles, venules, and capillaries, and what happens there?

they transport blood!! (oxygenated


The heart is an organ, a muscle, and it is part of the circulatory system.

Your stomach is part of the digestive system.

Our heart is a muscle and is the size of a fist.

The heart is the strongest muscle in the body.

A person has about 6 quarts of blood that circulate through out the body 3 times per minute.

White blood cells fight germs preventing the body from getting sickness. When the white blood cells see a type of germ that it has seen before, the memory cell reconizes it and then the killer cells destroy it before it has another chance of infecting your body.

Exercise is necessary to keep your heart strong and healthy.

The adult human heart has a mass between 250 and 350 grams.

It is located anterior to the vertebral column and posterior to the sternum.

It is enclosed in a double-walled sac called the pericardium.

Your heart is the most important organ in your body

The sac protects our heart.

When your heart stops pumping, YOU DIE!!!!!!!!!!!!!!
(Wow! REALLY?)

Your blood travels 19,000 kilometers (12,000 miles) every day

Respiratory System


What are the parts of the respiratory system?

The trachea,the lungs, and the diaphragm. They are all part of the respiratory system.
When you breath in you inhale in oxygen. When you exhale, you breath out carbon dioxide!
The Diaphragm During breathing the diaphragm contracts!
