Wouldn't this be more precise? (Click to Show Hidden Text)

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.

Yes, but he only asked for 2.

Question:
Which type of capillaries (continuous, fenestrated, or sinusoid) are the most common?

What are the three types of skin cancer, and how can you differentiate between them?

How accurately? (Click to Show Hidden Text)

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.
