Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ helps clot blood.
A
lymph nodes
B
platelets
C
red blood cells
D
white blood cells
Explanation: 

Detailed explanation-1: -Proteins on the exterior of your platelet walls are sticky to help it adhere to your blood vessels. When actively clotting, platelets extend filaments that resemble legs on a spider. These legs make contact with the broken blood vessel and other clotting factors to seal the damage and stop the bleeding.

Detailed explanation-2: -Platelets, or thrombocytes, are small, colorless cell fragments in our blood that form clots and stop or prevent bleeding. Platelets are made in our bone marrow, the sponge-like tissue inside our bones. Bone marrow contains stem cells that develop into red blood cells, white blood cells, and platelets.

Detailed explanation-3: -Fibrinogen… A specialized protein or clotting factor found in blood. When a blood vessel is injured, thrombin, another clotting factor, is activated and changes fibrinogen to fibrin.
