A human fetus develops at the mother’s body temperature. At birth, most newborns experience a drop in temperature, and their bodies must quickly do something about it. What they do is the same thing a hibernating mammal does as it rouses itself from its winter "snooze." During hibernation, an animal’s body temperature is low. In order to move about and take care of itself once awake again, the animal that has been hibernating must raise its body temperature. (William k. Purves et al., life: the science of biology) The definition is the primary pattern of organization in this passage.
This passage is explaining the process of hibernation and its importance in the animal life cycle.

The cardiovascular system is a system of organs that facilitates the circulation of blood to all parts of the body. Blood is required to reach all living cells as the blood carries essential elements for cell life and regulation, such as nutrients, amino acids, electrolytes,oxygen and hormones. The blood also has a role in maintaining body temperature, fighting diseases, maintaining a stable pH and maintaining homeostasis. The blood also carries carbon dioxide away from the cells. The cardiovascular system consists of a network of arteries, veins and capillaries, as well as the heart, which acts to pump blood around the body, Blood leaves the heart via arteries and return via veins. The lymphatic system transports lymph, typically at a much slower rate than blood. The lymphatic system is an important part of the immune system. Unlike the cardiovascular system, the lymphatic system is not a closed system. The cardiovascular system processes a lot of blood each day through capillary filtration, which separates the blood cells from the plasma. Not all plasma is re-absorbed into the blood vessels, and the lymphatic system is responsible for returning the remaining plasma to the cardiovascular system. <span> </span>
