Answers
Answer:
systole -darteries
As it beats, blood is forced against your artery walls.
Your systolic blood pressure is the top number on your reading. It measures the force of blood against your artery walls while your ventricles — the lower two chambers of your heart — squeeze, pushing blood out to the rest of your body.
veins -arteries
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.
