Amber Lankhorst Human Anatomy Notes: Body Planes and Regions- The left image shows three key anatomical planes of study: frontal, or coronal; transverse, or horizontal; and sagittal. The frontal plane is drawn through the body longitudinally, dividing the body into anterior and posterior portions. The transverse plane is drawn horizontally through the body, dividing it into superior and inferior parts. The sagittal plane is drawn through the body longitudinally, dividing it into left and right sides In the right image, terms of orientation are provided for comparison purposes. Superior refers to structures that are closest to the top of the skull. Inferior refers to structures closest to the plantar surface of the foot. Cranial relates to the head.

Tissue- groups of closely associated cells that are similar in structure and performance Study of tissues- Histology Four Primary Tissue Groups- Epithelial-Connective-Muscle-Nervous Epithelial-covering (epithe=laid on, covering) occurs in the body as 1)covering and lining epithelium 2) glandular epithelium Found on all free surfaces of the body such as the outer layer of the skin, lining of open cavities of digestive and respiratory systems, lining of the blood vessels and heart, covering the walls and organs of the closed ventral body cavity. Functions of Epithelial Tissue protection absorption filtration excretion secretion Characteristics Cellularity---- composed almost entirely of cells

AP BIOLOGY DIGESTION/HOMEOSTASIS 75 Name: Pledge: 1. Distinguish between an incomplete and complete DS. Give an example of an organism for each. (6) Incomplete systems have one ?pouch like? cavity which serves as both the mouth and anus. There is one opening for mouth and anus. Organisms: hydra, flat worm, invertebrates With a complete system the digestive tube has two openings for the mouth and anus. As well, other sites for the different processes of digestion like the stomach and the bowels. Organisms: all other phyla: humans, animals, 2. Why are some proteolytic enzymes produced in an inactive form? (4)

The Circulatory System Types of circulation: Gastrovascular cavities- Digests and distributes nutrients throughout the body of hydras and cnidarians. Open circulatory system- Blood and interstitial fluid are separated. This fluid is called hemolymph. The heart(s) pump hemolymph into sinuses where chemical exchange occurs between hemolymph and body cells. Open circulatory systems are in insects and arthropods. Advantages of an open circulatory system are less energy costly because of their low hydrostatic pressures and need less energy to maintain because they have no blood vessels.

Protein Digestion As I have suggested before, life is a system of cooperating enzyme reactions, and once again, enzymes are the prime movers in protein digestion just as they were in carbohydrate digestion. The enzymes for protein digestion are collectively called proteinases (protein-ACES) or proteases (pro-tea-ACES). Proteins are broken apart by the protein-digesting enzymes in a process called hydrolysis.
