The internal environment of the body is extracellular fluid, which refers to all of the fluids outside of our cells in our bodies – such as blood plasma, interstitial fluid, lymph and transcellular fluid. These fluids make up approximately 1/4 of body weight. Describe the three major types of lipids found in the body. (6 marks) * The three major types of lipids found in the body are triglycerides, phospholipids, and sterols (cholesterol). Triglycerides are fatty acids. Its functions include energy storage and the cushioning and insulating of the body and nerves. All nerves are wrapped in a myelin sheath; or lipid layer. Phospholipids are similar to triglycerides, but contain a phosphate group. It is a lipid bilayer – membranes in eukaryotic cells and the plasma membrane of cells. Sterols are made from lipids, but have no fatty acids in their structure. Cholesterol makes up sex hormones and carries lip-proteins. Describe briefly what is occurring at each step in the figure.

Epithelial Tissues What are five general characteristics which distinguish epithelial tissues? (1. Cellularity: tightly packed sheets of cells with little intercellular material between them 2. Basement membrane; the basal surface of ETs are anchored to underlying CT by a distinct basement membrane 3. Specialized contacts: tight junctions and desmosomes 4. Avascularity: contain no blood vessels; are nourished by nutrients which diffuse upward from underlying connective tissue through the basement membrane 5. Regeneration: high regeneration capacity due to rapid cell division ) Explain how the general morphology of epithelial cells may be deduced from the names of the epithelial tissues. (The names of the epithelial cells are characteristic of their structure: simple=single layer stratified=many layers squamous=flat cuboidal=cube shaped columnar=elongated ) Epithelial tissues specialized for secretion can be found in two types of glands. What are the gland types, and what are the functional characteristics of each?

...Chapter 4 Learning outcomes 4-1 Identify the four major types of tissues in the body and describe their roles. The four major types of tissues are epithelial, connective, muscle, and neural tissue. The functions of each are that the epithelial tissue covers exposed surfaces, lines internal passageways, and chambers, and forms glands. The connective tissue fills internal spaces, provides structural support for other tissues, transports materials within the body and stores energy. The muscle tissue includes the skeletal muscles of the body, the muscle of the heart, and the muscular walls of hollo organs, The neural tissue carries information from one part of the body to another in the form of electrical impulses. 4-2 Discuss the types and functions of epithelial tissue. The types of epithelial tissue include epithelia and glands. Epithelial provides four important functions that include physical protection, controls permeability, provides sensation, and produces specialized secretions. 4-3 Describe the relationship between structural and function for each type of epithelium. There are columnar, cuboidal, and squamous, which are flattened and scale-like cells. Basically columnar are much higher than they are wide, cuboidal look like squares, and squamous are flat like turtles and therefore not very tall at all. The relationship between each other is that squamous cells provide physical protection and performs absorption and secretion. The cuboidal structure relationship...

...05/12/2015 Abstract In common metabolic biochemistry human burns fuel (food) and generate energy. This energy is responsible off doing all types of processes of her body. Human body work in a very complex way when there is a demand on working muscles. During running so many changes are noticeable in human body. Those changes are faster heartbeat, sweating, hurting of muscles and very fast and deep breathing. These things consider normal doing marathon run. In order for runners to run marathon they have to train their body with hours of training. These trainings prepare their different body areas for example heart, lungs and red blood cells. Red blood cells are train so they can release maximum oxygen for muscle use during marathon run. Before the actual race to start runners brain prepared their body for “flight or fight” process. This is done by releasing epinephrine which is also known as Adrenaline. The chemical formula of adrenaline is C9H13NO3. With the release of epinephrine runner’s body get ready for action. Muscles are used in any type of exercise according to Shuo Qing, “during running muscles are working to accelerate body and keep it moving”. Muscles generate force by using energy. In human body, muscle work as an electric motors. They use the chemical called adenosine dry phosphate (ATP) for the source of energy. Three different types of food Carbohydrates, fats, and proteins can be used to generate ATP. But mostly Carbohydrates in the form of sugar or glucose molecules...

Which one would you find fossils in and why would you find fossils in this rock. Explain how fossils form. (6.E.2.4) Answer: Metamorphic Sedimentary Igneous You would find fossils in sedimentary rock Layers of soil are laid down on dead animals or plants embalming them. The minerals replace the organic matter creating the fossil. 2. Describe how the revolution of the Earth around the sun affects the seasons. Give one example supporting your answer (6.E.1.1) Answer: Revolution is defined as the orbital path a celestial body follows around the sun, or other celestial body. AS the Earth is close to the sun, the sunrays are able to reach the Earth a short distance allowing the Earth to become warmer. When the Earth moves away from the sun, the rays do not reach the earth. The Earth at a persistent distance does not allow the Earth to warm causing a change in seasons. 3.
