When healing from an external wound, what phase of healing presents with a scab formation?
A
Phase I
B
Phase II
C
Phase III
D
Phase IV
Explanation: 

Detailed explanation-1: -Clotting and scabbing phase has three main steps: Blood vessels around the wound narrow. This helps to stop the bleeding. Platelets, which are the clotting cells in blood, clump together to make a “plug” in the wound.

Detailed explanation-2: -Phase 1: Stop the bleeding (hemostasis) During this phase the body activates its emergency repair system to form a dam to block the drainage and prevent too much blood loss. Clotting also helps to close and heal the wound, making a scab.

Detailed explanation-3: -The second phase of wound healing is called the Inflammatory Phase. It involves phagocytic cells that release reactive oxygen species, lasting for up to seven days in acute wounds and longer in chronic wounds.

Detailed explanation-4: -There are four stages of wound healing-Hemostasis, inflammatory, proliferation, and maturation.

Detailed explanation-5: -When you get a cut, scrape, or puncture, the wound will bleed. The blood will start to clot within a few minutes or less and stop the bleeding. The blood clots dry and form a scab, which protects the tissue underneath from germs.
