Anatomy and physiology

• Responsiveness is the reactions to various stimuli.
• Growth, Increase in cell size (unicellular) and an increase in cell number (multicellular).
• Asexual is cell division (mitosis), one cell becomes two.
• Sexual is the union of sex cells (sperm and egg)
• Metabolism is the set of chemical reactions that converts food into energy.
• Homeostasis, maintaining the same state.
• Receptor, senses an environment change or stimuli.
• Control center, processes information supplied by the receptor and generates a response.
• Effector, an organ or cell that responds to the command of the control center.
• Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts.
• Structure is the arrangement of the relations between the parts.
• Physiology is the study of the normal function of cell, tissue, organs, systems, and organisms.
• Cytology the study of cells
• Histology the study of tissues.
• Surface anatomy is the study of superficial marking.
• Regional anatomy is the study of specific areas.
• Systemic anatomy is the study of systems.
• Developmental anatomy is the study that changes from conception to physical maturity.
• Cell physiology is the study of cells.
• Special physiology is the study of specific areas.
• Systemic physiology is the study of systems.
• Pathological physiology is the study of the effects of diseases on cell, tissue, organ, and system.
