I believe it's the cardiovascular system and the respiratory system.
All of them
The left subclavian artery doesn't feed the carotid (neck pulse) so your answer would be the wrist.
The Circulatory, Lyphatic, Integumentary, Muscular, and Nervous Systems.
Suppose you wanted to find out how your pulse rate was affected by climbing a flight of stairs. Compose a possible hypothesis. Would your research rely on quantitative or qualitative data?
the circulatory system
Directly, your skeletal system is affected since the Anterior Cruciate Ligament (ACL), being a ligament, connects the Femur to the Tibia. Indirectly, the affected systems would be: muscular, nervous, and integumentary systems.
A large EM Pulse would disable navigation and most control systems on aircraft such as A 380.
your judgment would be affected first.
the muscle, tissue, and possibly the bone
The rate of photosynthesis would be slowed down by increasing the thickness of a leaf. Leaves that are broad and thin offer the best conditions for the process.
Two come to mind: the nervous system and the muscular system.
So more light falls on. More energy is absorbed
