Has ducts; Does not produce hormones Abdominal; Abdomen Respiration Has ducts; Does not produce hormones Respiration Abdominal; Abdomen Film of H2O on body surface, heated by the body; water evaporates with the heat, body left cooler Film of H2O on body surface, heated by the body; water evaporates with the heat, body left cooler Too big to pass into Bowman s capsule Too big to pass into Bowman s capsule Animal that produces its own body heat; Body temp independent of environment temp Liquid part of the blood Animal that produces its own body heat; Body temp independent of environment temp Liquid part of the blood Maintaining water/salt balance; Osmoregulation Aorta Maintaining water/salt balance; Osmoregulation Aorta Piloerection; Vasoconstriction; Brain initiates increased metabolic rate Piloerection; Vasoconstriction; Brain initiates increased metabolic rate Carbohydrate; Fat; Fatty acids Carbohydrate; Fat; Fatty acids Urea; Salt; Uric acid Urea; Salt; Uric acid Diffusion; Transpiration; Through lenticels or stomata; Leaf fall Plasma that has entered Bowman s capsule Diffusion; Transpiration; Through lenticels or stomata; Leaf fall Plasma that has entered Bowman s capsule Ureter Ureter Elimination of waste products of metabolism Protein; Amino acid Urethra Elimination of waste products of metabolism Protein; Amino acid Urethra Fat/Adipose tissue; Trapped air/Hair Proximal convoluted tubule Usually reabsorbed Fat/Adipose tissue; Trapped air/Hair Proximal convoluted tubule Usually reabsorbed Glucose is small and passes through Vasodilation; Sweat secretion; Hairs lie flat, less air trapped Renal artery Glucose is small and passes through Vasodilation; Sweat secretion; Hairs lie flat, less air trapped Renal artery
