what is the blood flow (heart flow) in order
Right Atrium (RA)
Right vetricle (RV)
Lungs
Left Atrium (LA)
Left vetricle (LV)
body
3 types of blood vessels
-Artery
-Veins
-Capillaries
what is a blood vessel?
Blood vessels are a flexible, hollow tube that transport blood throughout the body
Thickest blood vessel that is made of 3 layers of cells and carries oxygenated blood away from the heart
Artery
Has 2 layers and carried deoxygenated blood back to the heart and lungs. (has valves to prevent the heart flow from going backwards)
Veins
the thinnest and smallest blood vessel.
Capillaries
-made of cardiac muscle
-it contracts and relaxes to pump blood
The heart
blood with low/less oxygen
Deoxygenated blood
Blood with high/more oxygen
Oxygenated blood
How much blood dose a average person have in their body
5 liters of blood.
the __________ _______ cause the heart to contract and relax a heartbeat. this impulse can be measured using an electrocardiogram (ECG). the pattern below can show doctors how your hear functions.
Electrical impulse
inside the _____ is divided into 2 sections(the left and right side)
Inside the heart
in the heart they act like a door, it prevents blood from flowing backwards.
valves
what is the function of the cardio vascular system?
-to deliver oxygen and nutrients to the cell to make energy.
-it removes carbon dioxide and other waste away from the cell.
The circulatory system is mode of? (include what it dose)
- the heart:pumps blood
- Blood: Carries oxygen and nutrients
- blood vessels: carries the blood and plasma
