What can happen if the sinoatrial node in humans is damaged?
Do all arteries carry oxygen-rich blood? Explain
Homework Answers
What can happen if the sinoatrial node in humans is damaged?
If the sino-atrial node in humans gets damaged then the heartbeat or heart rate becomes slow. this results in a decreased blood pressure. it leads to a condition called "bradycardia" in which a person has slow heart rhytm.
Do all arteries carry oxygen-rich blood? Explain
NO, not all arteries carry oxygen-rich blood. there is an exception. pulmonary arteries carry deoxygenated blood from the heart to the lungs to make it oxygen-rich.

What do all veins have in common? What do all arteries have in common? Circle or highlight the correct underlying term. The pulmonary arteries carry oxygenated/deoxygenated blood, while the pulmonary veins carry oxygenated deoxygenated blood. Circle or highlight the correct underlying terms. The pulmonary/systemic circuit carries deoxygenated blood to the right/ left side of the heart where it is pumped to the lungs. The pulmonary/systemic circuit carries deoxygenated/oxygenated blood to the cells of the body.

What would happen to you if you fell out of a spaceship, naked? Hollywood has given us many portrayals of this event, with the skin boiling or instantly freezing; but what actually happens, and what effect is most severe? The lack of oxygen is one: we know that humans can only survive a number of minutes without breathing. But there are a number of other factors to consider. (A) Assume a human is a 2 m tall cylinder of 75...
