Transcript of The Pulmonary Circulatory System - 7th Grade

The Pulmonary
Circulatory System

Blood Vessels and Disease Questions
Blood Vessels
Three main vessels
Arteries
Veins
Capillaries
Blood
Composed mainly of cells, cell fragments, and plasma.

Red blood
cells, found in plasma, (liquid part of blood) are able to bind both oxygen and carbon dioxide.
Lung Questions
Arteries
carry blood AWAY from the heart, they have thick walls.
Veins
carry blood back to your heart, are thinner than arteries, and have valves to prevent back-flow of blood.
Capillaries
connect arteries to veins, tiny compared to the other two.
The Pulmonary Circulatory System is made up of three parts:
1.

Lungs
2.

Heart
3.

Blood vessels

that connect everything
The
human heart
is a four chambered, muscular (cardiac muscle) pump. It will pump blood for as long as you live.
The top chambers are called
atria
, the bottom chambers are the
ventricles.
The heart has
valves
(flaps of tissue) that prevent blood from flowing backward in between heart beats
Heart Questions
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).
Lungs
Our
lungs

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
alveoli
, where the gas exchange takes place. If we spread out all of our lung tissue flat, it would cover this entire classroom.
Page 47 in your ISN
AVID: Lungs + Heart = Superteam?
The Heart
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?

Homework
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!
Each
atria
+
ventricle
form a team, one pair pumps to the lungs, the other pumps to the body.
Aorta
Pulmonary artery
Pulmonary vein
Mitral valve
Aortic valve
Superior Vena Cava
Inferior Vena Cava
Pulmonary valve
Tricuspid valve
