Replace a fuse after correcting the source of the overload.
I believe it would be C. Cracking a rib.
Because
- CPR doesn't involve the arms
- Headaches can happen at any age
- Not finding a pulse can happen with any person
- Cracking a rib would make the most sense to me due to that bone mass or density decreases as a person ages, the bones lose calcium and minerals causing them to deteriorate and become more brittle, which may result in them becoming easily breakable.
This is only my guess though, so don't take my word for it.
Hope it helps at least a little. (:
Blood is pumped through blood vessels all over our bodies because it carries the nutrients, mineral, and oxygen that every cell in our bodies need. It also carries out the metabolic waste away from its cell of origin.
Blood vessel is a tube-like structure in our body like vein, artery, and capillary. It carries blood through the tissues and organs within the body.
