When a blood vessel is damaged, platelets are the primary blood cells that are activated. They adhere to the site of injury and aggregate to form a temporary plug, initiating the process of hemostasis. This activation also triggers the release of various signaling molecules that further recruit additional platelets and promote the clotting cascade to stabilize the plug.
Platelets are cell fragments found in the blood that play a crucial role in blood clotting. They are activated when there is an injury to a blood vessel, and they help form a plug to stop bleeding.
The lack of nutrients inside a cell compared to the blood vessel creates a concentration gradient between the blood vessel and the cell. Due to the lower concentration in the cell, the nutrients diffuse through the blood vessel wall and into the cell.

A capillary is a blood vessel that is one cell thick for the absorption of nutrients and removal of wastes.
Why do you think that the blood cells stay in the blood vessels

Yes, the circulatory system can contain blood clots that form to stop bleeding from a damaged blood vessel. Proteins, such as antibodies and clotting factors, also circulate in the blood to help maintain homeostasis and fight infections.
