The main types of immune cells are white blood cells. There are two types of white blood cells â lymphocytes and phagocytes.

My background and current practice concerns the integration of surface design into new architectural builds; to meld conceptual aesthetics with architecture through means such as texture, colour or light. It is a collaborative process in which the concept is developed with the client.This may be referred to as âartâ or it may be experienced as subtle changes to surface. What matters, what it has to do, is to change and enhance the ambience of the space.ne could argue that Surface Design is, first and foremost, a mindset relating to daily experience of oneâs surroundings; and that understanding materiality is a key to controlling that experience. Students need to be aware of the way in which perceptions of colour and form are inherently linked to surface materials.
