The Pulmonary Circulatory System - 7th Grade
Transcript of The Pulmonary Circulatory System - 7th Grade
Blood Vessels and Disease Questions
Three main vessels
Composed mainly of cells, cell fragments, and plasma.
cells, found in plasma, (liquid part of blood) are able to bind both oxygen and carbon dioxide.
carry blood AWAY from the heart, they have thick walls.
carry blood back to your heart, are thinner than arteries, and have valves to prevent back-flow of blood.
connect arteries to veins, tiny compared to the other two.
The Pulmonary Circulatory System is made up of three parts:
that connect everything
is a four chambered, muscular (cardiac muscle) pump. It will pump blood for as long as you live.
The top chambers are called
, the bottom chambers are the
The heart has
(flaps of tissue) that prevent blood from flowing backward in between heart beats
Asthma and Arteriosclerosis
Asthma is a lung disease that causes airways to swell shut in certain situations (overexertion, exposure to smoke, and other irritating substances).
are the location of the gas exchange. In this process, we take on oxygen, and remove carbon dioxide.
Inside of our lungs, we have hundreds of millions of tiny
, where the gas exchange takes place. If we spread out all of our lung tissue flat, it would cover this entire classroom.

AVID: Lungs + Heart = Superteam?
Arteriosclerosis is hardening and blockage of blood vessels, usually due to poor diet and exercise (and smoking). Can cause heart attacks and other heart related problems.
How many chambers in the heart?
What do we call the different chambers?
Why does the heart need valves?
What happens in the lungs?
What do we call the tiny parts of the lung that carry out gas exchange?
-What is different between artery's and veins?
-How are capillaries different from the other two blood vessels?
-What is Asthma?
-What is arteriosclerosis?

On Page 46 of your ISN, draw and label the path that blood takes in your body (how it circulates in the body). Make sure to include the heart and the lungs!
form a team, one pair pumps to the lungs, the other pumps to the body.
