Blood
What are the 4 main components of blood?
Red Blood Cells, White Blood Cells, Platelets, and Plasma.
What are 4 chambers of the heart?
Right Atrium, Right Ventricle, Left Atrium, Left Ventricle.
What is a major function of coronary arteries and coronary veins?
Coronary arteries deliver blood to capillaries, who deliver oxygen and glucose to the heart. Coronary veins will take the deoxygenated blood to the heart.
Which type of blood pressure is most harmful for your body?
Both high and low blood pressure.
What system transports nutrients and other life-sustaining resources in your body?
The circulatory system, which includes the cardiovascular and lymphatic system.
What does plasma do?
Carries crucial things such as nutrients and proteins throughout the body.
Through what does deoxygenated blood enter the heart?
Vena Cava (Inferior)
What would occur if a coronary artery was blocked?
It would lead to a heart attack.
What is blood pressure?
The force with which the ventricles of the heart contract is what creates blood pressure.
In which loop of the double loop system is where the oxygenated blood moves from the heart out to our body and the deoxygenated blood comes back to our heart?
Loop No. 2 of the double loop system.
What are platelets and what is their function?
Platelets are small cell fragments that clump together to form a clot when you get a cut, preventing too much blood from leaking out.
What happens to oxygen in blood when it leaves the heart?
It travels through the body & goes through all the cells who need it.
Which major artery carries out oxygenated blood throughout the body?
Aorta.
What would happen if you didn't have blood pressure?
Without blood pressure, blood would not be able to reach all parts of your body.
Through what process does materials such as oxygen and nutrients move through capillary walls?
Diffusion.
What are white blood cells?
These are the body's defense team, fighting off germs and infections by identifying and destroying them.
What is the bottom right chamber of the heart (from our POV)?
Left Ventricle.
Which veins bring in oxygenated blood from the lungs?
Pulmonary veins.
What are some activities that would increase your heart rate?
Sports, Push-ups, Jumping Jacks, Stressful and/or Nervous situations, etc.
Diffusion occurs when oxygen, nutrients, and other materials move through capillary walls. What concentration to what concentration does it move?
High concentration to Low concentration.
What protein do red blood cells contain?
What is the top left chamber of the heart (from our POV)?
Right Atrium.
Arteries usually carry blood away from the heart, while veins carry blood into the heart.
What would happen if you had a very high blood pressure?
If you had a very high blood pressure, then you would hurt the arteries in your heart, which can lead to an abnormal heart rate, or maybe even a heart attack in some serious cases.
What is the main thing that makes oxygen and nutrient movement possible?
A series of blood vessels (veins and arteries) make this possible.
