This system can be difficult to find as it is small as well as extremely dorsal and posterior to the other systems. Repeat this with the back leg. [19] Because the fetal pigs were still in the mothers uterus, teeth will still form which supports reasons for hollow unerupted teeth that may be seen. Observe the renal capsule, the thin membranous covering of the kidney. Contraction of the diaphragm forces air into the lungs. Figures 29 and 30 summarize the circulatory system of a mammal. Locate the two kidneys in the abdominal cavity. Find the adrenal glands: small, white bands of tissue on the top, inside edge of each kidney. Contraction of the diaphragm forces air into the lungs. The arteries have been filled with red latex and the veins with blue. The urinary system consists of 4 major organs; the kidneys, ureters, urinary bladder and the urethra.Together these organs act to filter blood, remove waste products, create urine and transport urine out from the body. The epiglottis projects up through the soft palate into a region called the nasopharynx. 0000007704 00000 n Weight is also not a factor of survival rate because a healthier diet does not lead to a heavier offspring or a greater chance of live birth.[11].
