2. Anatomy is the study of the human body structures that can be seen with the naked eye and how the body parts are organized; it is the science of the structure of organisms or of their parts. Physiology is the study of the functions or activities performed by the body's structures. Histology, also known as microscopic anatomy, is the study of science of the minute structures of organic tissues.
3. Basic Structures of a Cell: Protoplasm- colorless jelly-like substance found inside cells in which food elements such as protein, fats, carbohydrates, mineral salts, and water are present Nucleus- dense, active protoplasm found in the center of the cell; plays an important part in cell reproduction and metabolism Cytoplasm- all the protoplasm of a cell except that which is in the nucleus; the watery fluid that contains food material necessary for growth, reproduction, and self-repair of the cell Cell membrane- part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell
4. Metabolism is a chemical process taking place in living organisms whereby the cells are nourished and carry out their activities. Anabolism is constructive metabolism; the process of building up larger molecules from smaller ones. Catabolism is the the phase of metabolism that involves the breaking down of complex compounds within the cells into smaller ones resulting in the release of energy to perform functions such as muscular movement or digestion.
5. Four Types of Tissues:
Connective- fibrous tissue that binds together, protects, and supports the various parts of the body such as bone, cartilage, and tendons
Epithelial- protective covering on body surfaces, such as the skin, mucous membranes, and the lining of the heart, digestive and respiratory organs and glands
Muscle- tissue that contracts and moves various parts of the body
Nerve- tissue that controls and coordinates all body functions
6. Organs are structures composed of specialized tissues and performing specific functions.
7. 9 Major Organs:
Brain- controls the body.
Eyes- controls the body.
Heart- circulates the blood.
Kidneys- Excrete water and waste products.
Lungs- supply oxygen to the blood.
