Study Notes
Organization of the Human Body
- The human body is composed of:
- Cells: the basic structural and functional units of life
- Tissues: groups of similar cells that perform specific functions
- Organs: structures composed of two or more types of tissues that work together to perform specific functions
- Organ systems: groups of organs that work together to maintain homeostasis and perform specific functions
Cell Structure and Function
- Cell membrane: a thin layer of lipid and protein molecules that surrounds the cell and regulates what enters and leaves
- Cytoplasm: a gel-like substance inside the cell membrane where metabolic processes occur
- Nucleus: the control center of the cell where DNA is stored
- Mitochondria: organelles responsible for generating energy for the cell
- Ribosomes: organelles responsible for protein synthesis
Tissue Types
- Epithelial tissue: forms the lining of organs and glands, and regulates what enters and leaves the body
- Connective tissue: provides support and structure to the body, and connects organs and tissues
- Muscle tissue: responsible for movement and contraction
- Nervous tissue: responsible for transmitting and processing information
Organ Systems
- Nervous system: responsible for controlling and coordinating body functions
- Circulatory system: responsible for transporting oxygen and nutrients to cells, and removing waste products
- Respiratory system: responsible for exchanging oxygen and carbon dioxide
- Digestive system: responsible for breaking down and absorbing nutrients
- Endocrine system: responsible for producing and regulating hormones
- Immune system: responsible for defending the body against pathogens and disease
- Integumentary system: responsible for protecting the body from external damage and regulating body temperature
- Muscular system: responsible for movement and maintaining posture
- Skeletal system: provides support and structure to the body
- Urinary system: responsible for filtering waste and excess substances from the blood
Human Body Systems Interactions
- Homeostasis: the ability of the body to maintain a stable internal environment despite changes in external conditions
- Negative feedback loops: mechanisms that counteract changes in the body to maintain homeostasis
- Interactions between organ systems: the body's systems work together to maintain homeostasis and perform specific functions
Organization of the Human Body
- Human body is composed of cells, tissues, organs, and organ systems
- These components work together to maintain homeostasis and perform specific functions
Cell Structure and Function
- Cell membrane regulates what enters and leaves the cell
- Cytoplasm is the site of metabolic processes
- Nucleus is the control center of the cell where DNA is stored
- Mitochondria generate energy for the cell
- Ribosomes are responsible for protein synthesis
Tissue Types
- Epithelial tissue forms the lining of organs and glands, and regulates what enters and leaves the body
- Connective tissue provides support and structure to the body, and connects organs and tissues
- Muscle tissue is responsible for movement and contraction
