Characteristics of Cardiovascular System
Cardiovascular systems job:
Circulates blood throughout the body
Where is the heart located?
In the middle of your chest with a slight tilt to the left
What are blood vessels?
Different passages that carry blood throughout body, and oxygen to internal organs
Network of arteries that bring oxygen rich-blood from your heart to all of your body’s cells
Arterial System
What is blood pressure?
the force of blood against the walls of your arteries and is measured in millimeters of mercury mmHg
How many loops in cardiovascular system
2
Three layers of the wall of the heart
Epicardium, Myocardium, Endocardium
Blood vessels include
Arteries, Veins, Capillaries
Arteries color
Red
What is cardiac output
factor that affects blood pressure, volume discharged from the ventricle per minute
Pulmonary Circulation's function
Allows oxygenation of the blood
How many chambers in the heart
4
What's an artery
blood vessels that bring oxygen rich blood from your heart to all of your body's organs
What distributes oxygen, nutrients and hormones throughout your body
Arteries
What is viscosity
factor that affects blood pressure, the amount of difficulty molecules experience when flowing past one another
Systemic Circulation's Function
Allows oxygenated blood and nutrients to reach the rest of the body
Thin wall that separates the atrium
Interatrial Septum
What's a vein
blood vessels that carry deoxygenated blood back to heart
Network of veins that bring deoxygenated blood back to your heart
Veins
What's systolic pressure?
Maximum pressure achieved during ventricular contraction
In addition to circulation, what delivers oxygen and nutrients to cells as well as removing waste products
The Cardiovascular System
How does blood flow
right atrium --> right ventricle --> pulmonary artery --> left atrium --> left ventricle --> aorta --> throughout body
What's a capillary
Tiny blood vessels that connect your arteries and veins as well as exchanging nutrients between blood and tissues
Veins color
blue
What's diastolic pressure?
lowest pressure that remains in the arteries before the next ventricular contraction
