No, electrical activity in the heart moves from proximal to distal.
Distal
TRUE
Proximal LAD stands for "proximal left anterior descending artery," which is a part of the left main coronary artery. It is a critical blood vessel that supplies oxygenated blood to a large portion of the heart muscle. Blockages or narrowing in the proximal LAD can lead to serious heart conditions like myocardial infarction (heart attack).
ascending aorta
In terms of the respiratory tract, the pharynx is proximal to the lung. It comes before the lungs as air moves through the respiratory tract.
The heart is both medial AND deep to the lungs.
During CPR the lungs and heart are stimulated.
The organs protected by the rib cage include the heart, lungs, stomach, and liver.
What behaviors can harm you lungs and heart?
the heart is medial/proximal to the rib cage
Medial basically refers to being in the middle. Lateral basically refers to on or at the sides. The lungs are located on either side of the heart, so they are lateral to the heart.
