Question

which of the following best describes the part of the blood composition that forms clots around wounds to prevent blood loss?

• plasma
• platelets
• white blood cells
• red blood cells

Explanation:

🆕 New Concept Discovered: Composition and Functions of Blood
How different blood components keep us alive and healthy.

Step 1: Identify the function of each blood component

To find which component is responsible for forming clots, let's look at what each part of the blood does:

• Plasma: This is the liquid portion of the blood. It is mostly water and serves to transport nutrients, hormones, waste products, and proteins throughout the body.
• Platelets (thrombocytes): These are small, cell fragments that gather at the site of an injury. They stick to the damaged blood vessel wall and clump together to form a plug (clot) to stop bleeding.
• White blood cells (leukocytes): These cells are a key part of the immune system. Their primary job is to defend the body against infections, viruses, and foreign invaders.
• Red blood cells (erythrocytes): These cells contain hemoglobin and are responsible for carrying oxygen from the lungs to the rest of the body.

Step 2: Match the function to the question

The question asks for the part of the blood composition that forms clots around wounds to prevent blood loss.

Based on the functions identified above, platelets are the specific components responsible for blood clotting (coagulation).

Answer:

Platelets
