Blood can either be bright red, or a very dark red (almost blue looking). What is the cause of this color change?
Red- Oxygenated
Dark- Deoxygenated
What parts of the heart are structures A, and B?
A= Right Atrium
B= Aorta
What is the function of an artery?
brings oxygen rich blood from your heart to all of your body cells.
When your heart rate increases, what else increases?
Breathing Rate
What structures are involved in the circulatory system?
Heart, veins, arteries
What happens to blood once it travels to the lungs?
It receives oxygen and releases CO2.
What are structures C and D?
C= Left Ventrical
D= Inferior Vena Cava
What is the function of your heart?
Pumps blood around the body as it beats.
What is a potential problem with having high levels of cortisol in your system?
It's unhealthy over longs periods of time, could lead to heart disease/high blood pressure, diabetes, and even shorter lifespans.
What system works most closely with the circulatory system?
Respiratory System
Which organ pumps and circulates blood?
What are structures E and F?
E= Right Ventrical
F= Left Atrium
What is the function of a vein?
Brings deoxygenated blood back to the heart.
How does your body respond to emotions or stress? Give specific examples.
Scared- heart rate rises, breathing rate rises and cortisol levels and adrenaline levels rise as well.
Stressed- same
Excited- same except only adrenaline is released, not cortisol.
What is the goal of the pulmonary circuit?
To get new oxygen in the blood
What does blood do for the body cells?
Transports Oxygen, Nutrients, and helps remove waste (CO2).
What are structures G and H?
BONUS 100 Points: What is the structure without a letter?
G= Tricuspid Valve
H= Superior Vena Cava
Bonus: Pulmonary Artery!
What is the function of the different heart valves?
Prevent the backflow of blood. (One way inlets and one way outlets for blood through the heart).
What are some ways you can "hack" your stress response, and regulate your heart and breathing rates?
Box breathing, stress training, positive self talk.
What is the goal of the systemic circuit?
Supply the body cells with oxygen.
What are the three structures that blood flows through?
Capillaries, Arteries, and Veins
What are structures I and J?
I= Mitral Valve
J= Pulmonary Veins
What is the function of a capillary?
Transfers oxygen from the lungs to the blood, or CO2 from the blood to the lungs.
Why does your heart rate need to rise in stressful or potentially dangerous situations?
Invokes your fight or flight response, gets you ready to act or move quickly if needed. Body's safety mechanism.
What can give a person an increased risk of heart disease, and how can a person lower their risk?
Increased by: Smoking, Obesity, Not working out, Family history, Cholesterol levels
Can be decreased by: More exercise, eating healthy, losing weight if needed, stop smoking (or any other unhealthy habits).
