It is possible that this is not pathological, but is associated with certain fatty diets. 12 Blood vessels and cells Blood vessels consist of layers of smooth muscle, connective tissue fibres and an inner lining of endothelial cells. The connective tissue contains collagen and elastic fibres. Arteries are thicker than veins whilst capillaries are much simpler, with an endothelium, basement membrane and pericytes. All fish have nucleated blood cells, which distinguish them from higher vertebrates. Blood cells are suspended in a fluid called plasma, which is composed of water plus various proteins, carbohydrates, lipid and ions.

Histology The atrium is thin and contains few muscle fibres, whereas the ventricle is much thicker and is made up of the main cardiac muscle which forms the inner myocardium and the outer epicardium. Each cardiac muscle fibre is a single cell with its own nucleus, which is joined by discs to other fibres. 13a). The heart muscles are connected to the vagus nerve and produce rhythmical contractions. The bulbus arteriosus is a thickwalled part of the heart made up of elastic connective tissue and leads into the ventral aorta.

This area of the kidney serves both as a primary and secondary lymphoid organ. Some authorities have suggested that the kidney resembles the mammalian lymph node and is associated with antibody production, but it also houses differentiating blood cells and thus is similar to the mammalian primary lymphoid organ, the bone marrow. The leucocyte content of the head kidney is similar to that of the thymus although there are quantitative differences. e. melanin, haemosiderin, lipofuscin – the so-called melanomacrophages – also occur.
