Parts of the heart
What type of blood is found in the right atrium?
Deoxygenated blood
What makes oxygenated blood oxygenated?
Carries high levels of oxygen and low levels of carbon dioxide
What are arteries?
blood vessels that carry blood away from the heart to the rest of the body
True or false laughing is good for the heart
True
What type of blood is in the left ventricle?
Oxygenated
What are the two lower chambers in the heart called?
Right ventricle and lower ventricle
What makes deoxygenated blood deoxygenated?
Carries low levels of oxygen and high levels of carbon dioxide
What are the three types of blood vessels?
Veins, arteries, capillaries
Why is it important to keep your heart healthy?
Your life pretty much depends on the heart, the heart is what brings life to every other organ in the body by pumping blood to every cell within you
What type of blood is in the right ventricle?
Deoxygenated
What does the right atrium do?
Receives blood returning from the body via the vena cava and passes it to the right ventricle
What colour is oxygenated blood and why?
Bright red or crimson because oxygen binds to hemoglobin
What are capillaries?
Carries blood to and from body’s cells
What are the 5 main parts of the circulatory system?
The heart, blood vessels, arteries, veins and capillaries
What picks up and drops off oxygen?
The capillaries
What does the right ventricle do?
Pumps the blood to the lungs to pick up oxygen and release carbon dioxide
What colour is deoxygenated blood and why?
Color is dark red, black-ish, blue-ish because of how oxygen changes the shape and light-reflecting properties of hemoglobin
What are veins?
blood vessels that carry oxygenated blood from your body’s tissues back to your heart
How many times a day does your heart beat?
100,000 times a day
Where does carbon dioxide flow from the lungs?
Throughout the veins then to the vena cava
What does the left ventricle do?
Pumps oxygen-rich blood through the aorta to supply the rest of the body
What happens when deoxygenated blood reaches the lungs?
becomes oxygenated again and gets transported to the the left atrium then receives freshly oxygenated blood upon returning
What are two reasons we have blood vessels?
To form a closed network of tubes that transport blood to every part of our body, delivering what cells need and carrying away waste
Help control body temperature and manage body heat
Approximately how long are blood vessels in our body?
100,000 km
What happens after the blood reaches the left atrium?
It’s pushed to the left ventricle, then to the aorta
