Step 1
Explain why platelets are important to athletes in contact sports such as boxing.
Answer
Platelets play a crucial role in the body's healing process, particularly for athletes who are at risk of cuts and injuries during contact sports like boxing. They facilitate the clotting of blood, which is essential to prevent excessive blood loss after an injury. This is particularly important for a boxer, as a quick response to bleeding allows them to continue competing in the match or prolong their training without critical interruptions. Specifically, platelets form a scab over the wound, protecting it and promoting healing. Thus, their function is vital for the athlete's endurance and performance.
Step 2
State one function of plasma.
Answer
One function of plasma is to transport nutrients and waste products throughout the body. Plasma serves as the liquid medium in which red blood cells, white blood cells, and platelets are suspended, ensuring that essential substances like glucose and electrolytes reach the cells while waste products are carried away for excretion.
