This image shows a human fetus at 11 weeks of development, approaching the end of the first trimester.

Key features at 11 weeks:

Size & Growth: The fetus is about 4–5 cm long (roughly the size of a fig) and is rapidly gaining weight.

Head & Face: The head still makes up a large portion of the body, but facial features are becoming more refined — the eyes are closed, the ears are more defined, and the nose bridge is forming.

Limbs & Movements: Arms and legs are fully shaped, with fingers and toes well separated. The fetus can now bend elbows and knees, and tiny movements are becoming more coordinated (though still too small for the mother to feel).

Skin & Circulation: Skin is still very thin, showing a fine network of blood vessels beneath.

Internal Development: Bones are hardening, and the liver is producing red blood cells until the bone marrow takes over later.

Posture & Behavior: The fetus often assumes a curled position, occasionally bringing its hands toward its face — as seen in this image.

What is Inflammation?

Inflammation is a complex biological response to harmful stimuli, such as pathogens, damaged cells, or irritants. It's a protective mechanism that helps the body eliminate the cause of injury, repair damaged tissue, and promote healing.

Pathophysiology of Inflammation:

The inflammatory process involves multiple cellular, molecular, and vascular components.

1. Vascular Response
- Vasodilation: Blood vessels dilate, increasing blood flow to the affected area.
- Increased Vascular Permeability: Blood vessels become more permeable, allowing fluid and proteins to leak into the interstitial tissue.
- Leukocyte Recruitment: White blood cells, such as neutrophils and macrophages, are recruited to the site of inflammation.

2. Cellular Response:
- Neutrophils: These white blood cells are the first line of defense, helping to eliminate pathogens and foreign particles.
- Macrophages: These cells play a crucial role in the inflammatory process, helping to e
