The gills of a fish The gills function similarly to the bronchi within mammalian lungs. They have a large surface area and are highly vasculated, meaning they contain thousands of small blood vessels. This maximizes the amount of dissolved oxygen that can be extracted from the water. The gener...
respiratory surface a special area that is developed in order to satisfy the requirements for gaseous exchange in larger organisms. Examples include external gills, internal gills, lungs, and the insect tracheae. The surfaces are thin and moist with a differential gradient maintained between the air...
The respiratory surface area of the gill in relation to body mass of the facultative air-breathing loricariid fish Rhinelepis strigosa was analyzed using logarithmic transformation (log Y = log a + b log W) of the equation Y = aWb. The data revealed differences in growth pattern for each ...
Adj.1.dorsal- belonging to or on or near the back or upper surface of an animal or organ or part; "the dorsal fin is the vertical fin on the back of a fish and certain marine mammals" ventral- toward or on or near the belly (front of a primate or lower surface of a lower anima...
The respiratory burst response of surface-adhering leukocytes. A key to tissue engineering Håkan Nygren, ... Noushin Yahyapour, in Colloids and Surfaces B: Biointerfaces, 2001 A weaker respiratory burst can be obtained in cell-free systems, where the NADPH-oxidase can be assembled and activated...
Marine mammals also breathe air, and must come up to the surface of the water to breathe. They have small lungs in relation to their body size compared to humans to reduce problems of nitrogen building up in the blood caused by diving. They have to make sure no water gets into the gas...
surface IgT which represents the predominant B-cell subset in the trout gut-, skin- and nasal-associated lymphoid tissues (GALT, SALT and NALT)8,9,10. Overall, fish IgT represents the most ancient mucosal immunoglobulin found in a vertebrate species. In fact, the newly attributed role of ...
(sema3a)69. The binding of NRP1 on the surface of endothelial cells by VEGFA stimulates vascularization (i.e., blood vessel formation) via vasculogenesis and angiogenesis, while the combination of NRP1 and SEMA3A inhibits vasculogenesis70,71(Fig.2g). VEGFA and NPR1 show lung-specific ...
in the thoracic cavity of the chest. Anatomically, the lungs are spongy organs with an estimates total surface area between 50 to 75 sq meters. The primary function of the lungs is to facilitate the exchange of gases between the blood and the air. Interestingly, the right lung is quite big...
