Circulatory And Respiratory System Flashcards
What are the five main functions of the circulatory system?
- Maintaining body temperature
- Fighting disease
- Carrying chemicals
- Carrying food, water, and oxygen
- Removing waste from the cells
Which direction do veins carry blood?
To the heart
Which directions to arteries carry blood?
Away from the heart
What is the purpose of the capillaries?
To allow gas exchange
If I am a red blood cell in the Longs, where is my next stop?
Left atrium
If I am a red blood cell in the body where is my next stop?
Right atrium
If I’m a red blood cell in the right ventricle where is my next stop?
Lungs
Where is the circulatory system get the oxygen it is responsible for delivering?
From the lungs
Each upper chamber of the heart is called a/an
Atrium
Each lower chamber of the heart is called a/an
Ventricle
The left side of the heart pumps oxygen rich blood to the______ while the right side of the heart pumps oxygen poor blood to the______.
Body
Lungs
Where does the exchange of blood and oxygen take place in the lungs?
Capillaries
What are the four components to Blood?
- Platelets
- Plasma
- Red blood cells
- White blood cells
What do red blood cells do?
Red blood cells transport oxygen and carbon dioxide to and from the cells.
What do white blood cells do?
White blood cells identify and destroy pathogens(disease causing microorganisms)
What do platelets do?
Platelets are involved in blood clotting and regeneration of connective tissue.
What part of Blood with Cheerios represent and why?
Red blood cells because they are similar in shape and size.
Your body needs oxygen in order to get______ from the food you eat.
Energy
There are six places oxygen needs to travel through on its way through the respiratory system to the circulatory system lets them in order.
- Nasal cavity
- Pharynx
- Trachea
- Bronchi
- Bronchioles
- Alvioli
What is the purpose of the bronchi?
To lead the oxygen into the lungs.
What is the purpose of the alveoli?
To exchange the oxygen and carbon dioxide.
What does the nasal cavity do?
Filters and warms the air that goes to the lungs.
What is another name for your windpipe?
Trachea
What is another name for the throat?
Pharynx
And moves into the lungs when the diaphragm muscle does what?
Goes down or contracts.
What are the alveoli surrounded by that lets the oxygen into the blood?
Capillaries
Describe how the respiratory and circulatory system are connected.
The respiratory system is responsible for getting oxygen into the body in the circular system takes the oxygen and distributes it.
What does the circulatory system consist of?
Your heart, blood, and blood vessels, arteries, veins, and capillaries.
What does the atrium do?
The atrium transports the blood and nutrients to the cells.
What does the ventricle do?
The ventricle pushes the blood out of the heart.
Describe how the heart works in three phases
- blood enters the atria and The left atrium receives oxygen rich blood. The left atrium receives oxygen poor blood.
- What is squeezed into ventricles
- Ventricles push blood out of the heart. Right goes into the lungs left goes to the rest of the body.
Describe the first loop of blood flow.
The right ventricle pumps oxygen poor blood into the lungs. The Blood takes up oxygen in the capillaries.
Describe the second loop loop of blood flow.
Oxygen rich blood is pumped into arteries and then capillaries. Oxygen, water, and nutrients are transported to the cells of the body. Where is the carried away.
