double circulation in mammals. De-oxygenated blood from the body enters the heart, which is then pumped to the lung to be oxygenated. The newly oxygenated blood enters the heart and then pumped to the whole body. Use the structures given below to describe the direction of blood flow. Start with the first structure that takes the de-oxygenated blood to the heart and end with the last structure that takes the oxygenated blood to the body (Pages 902, Fig 42.6). Left semilunar valve, right semilunar

diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.A "diaphragm" in anatomy can refer to other flat structures such as the urogenital diaphragm or pelvic diaphragm, but "the diaphragm" generally refers to the thoracic diaphragm. Other vertebrates such as amphibians and reptiles have diaphragm-like structures, but important details of the anatomy vary, such as the position of lungs in the abdominal cavity.

in our bodies DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies Cell wall definition.

Unit 303, Outcome 2, Skin & Hair The skin is the largest organ of the body, with a total area of about 20 square feet. The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. Skin has three layers: * The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. * The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands

The organs in a human body are made of a structure called tissue which is also made of cells with similar functions. Tissues are commonly categorized by the function of the cells that make them up. There are four types of tissues in the human body which are nervous, epithelial, muscular, and connective. The main components that make up nervous tissue are nerve cells or neurons. An important structure of nervous tissue are the neuroglial cells. Neurons are a specialized type of cell that receive and
