IgG: Most common and versatile, only class transferred across placenta, and is an opsonin (enhances phagocytosis). IgA: Second most common major class of Ig in secretions like mucus. IgM: Third most common, first made by fetus, good at clumping microorganisms in preparation for excretions. IgD: Not very common mainly found on B cell surfaces. IgE: Least common involved in allergic reactions helpful in diagnosing parasites.

The three types of skin cancer are: Basal Cell Carcinoma, Squamous Cell Carcinoma, and Malignant Melanoma. Basal Cells Carcinoma has a pinkish, raised, and waxy surface. Squamous can look like a dull, rough, redish, and raised skin lesion. It occurs mostly on sun-exposed areas. Malignant Melanoma is usually asymmetric, with irregular borders, variation of coloration in the area, and the diameter is bigger than 6 mm.

T-cells mature in the thymus, and B-cells mature in the bone marrow.
