Biggest
The Veins are the ____ ____ vessels in the body
2nd biggest
The Capillaries are the ___ vessel in the body.
Smallest
Where does oxygen-rich blood leave from the heart?
The aorta.
How does the heart pump?
Electrical impulses.
What do the artery's do?
Carry oxygen and nutrients away from your heart to your body's tissue.
Veins contain blood. True or False.
False.
What are capillaries made of.
A single layer of endothelial cells.
Oxygen rich blood is the most important blood.
True or False.
True.
The heart is the hardest working muscle in the body.
True or False.
True.
What is the biggest artery?
Aorta.
Which part of your body is blood drawn from your vein(s).
Middle of your arm/ Inferior to the humerus & epidermis to the skin.
What is the function of the Capillaries.
Take waste products away from your tissues.
True or False.
True.
The heart is the strongest muscle in the body. True or False.
False.
What type of oxygen leaves the aorta.
oxygen-rich blood.
Carry wastes and low-oxygenated blood to the heart from the body.
Do capillaries carry blood away from the heart or to the heart.
Neither. They connect veins and arteries to exchange substances.
What system is the exchanging blood circulation of oxygenated and de-oxygenated.
Systemic Circulation.
Why does your heart contract within the valves.
Bonus Question (400 points) - Around how many beats does your heart beat per minute.
To prevent clogs in the chambers.
Between 60 and 100 beats per minute.
Do Arteries Harden? If so, when does it happen/occur.
Yes. Artery hardening occurs when fat, cholesterol, and other substances build up in the walls of arteries.
Why do veins twist?
If these valves are weak or damaged, blood can flow backward and pool in the veins, causing the veins to stretch or twist.
What are the sites for capillaries?
For adults/children: Earlobes, Ring fingers.
For Infants: Heels
From what vessel does the low-oxygenated blood come from? Where does the low-oxygenated blood enter and in what chambers or parts of the heart it enters? Later in what vein does this blood goes to get oxygen and in what lung does it go?
From the veins it goes to the inferior vena cava and it goes to the right atrium and right ventricle, then it goes to the pulmonary vein to the left lung for oxygen.
