Blood Clotting Quiz

What are the tiny cell fragments that float around in our blood?

• Plasma

• Platelets

• White blood cells

• Red blood cells

Answer explanation

Platelets are the tiny cell fragments that float around in our blood. They play a crucial role in blood clotting and preventing excessive bleeding.

During blood clotting, which protein helps make the platelet plug stronger?

• Hemoglobin

• Albumin

• Fibrinogen

• Collagen

Answer explanation

Fibrinogen is the protein that strengthens the platelet plug during blood clotting.

What do soluble fibrinogen proteins transform into when they encounter external chemicals at a wound?

• Red blood cells

• Platelet plug

• Sticky fibrin fibers

• Collagen fibers

Answer explanation

Soluble fibrinogen proteins turn into sticky fibrin fibers when exposed to outside chemicals at a wound.

During blood clotting, what does the fibrin mesh hold together, according to Abigail, Maya, and Olivia?

• Red blood cells

• Platelets

• Plasma

• White blood cells

Answer explanation

The fibrin mesh formed during blood clotting holds together platelets.

During blood clotting, what is the main thing that the clot prevents from entering our body?

• Nasty pathogens

• Carbon dioxide

• Oxygen

• Nutrients

Answer explanation

The clot prevents nutrients from entering our body during blood clotting.

As the wound heals, what does the scab formed from the clot do?

• Causes infection

• Protects the wound

• Stops platelet production

• Prevents blood clotting

Answer explanation

The scab formed from the clot protects the wound as it heals.

What makes platelets and fibrin sticky during blood clotting?

• Exposure to light

• Exposure to water

• Exposure to outside chemicals

• Exposure to oxygen

Answer explanation

During blood clotting, platelets and fibrin become sticky due to exposure to outside chemicals.

Why do platelets and fibrin only become sticky after exposure to certain factors?

• To ensure normal blood flow

• To prevent blood clotting

• To promote wound healing

• To avoid infection

Answer explanation

Platelets and fibrin become sticky after exposure to certain factors to ensure normal blood flow.
