이 집합의 용어 (28)
Anatomy is the study of the structure and shape of the body and its parts.
Physiology is the study of how the body and its parts function.
Levels include chemical, cellular, tissue, organ, organ system, and organism levels.
Homeostasis is the body's ability to maintain a stable internal environment despite external changes.
Epithelial, connective, muscle, and nervous tissues.
Epithelial tissue covers body surfaces, lines cavities, and forms glands.
Cell membrane, cytoplasm, and nucleus.
The cell membrane controls what enters and leaves the cell and provides protection.
An organ system is a group of organs that work together to perform a specific function.
The skeletal system provides support, protection, and aids in movement.
Anatomy studies structure; physiology studies function.
The nervous system detects changes and sends signals to maintain homeostasis.
Connective tissue supports, binds, and protects other tissues and organs.
Skeletal, cardiac, and smooth muscle tissues.
The cardiovascular system transports blood, nutrients, gases, and wastes throughout the body.
The respiratory system facilitates gas exchange, bringing in oxygen and removing carbon dioxide.
The cell is the basic structural and functional unit of life.
The digestive system breaks down food and absorbs nutrients.
The urinary system removes waste products from the blood and maintains water balance.
The anatomical position is standing upright, facing forward, arms at sides, palms facing forward.
Dorsal cavity (cranial and spinal) and ventral cavity (thoracic and abdominopelvic).
The integumentary system protects the body, regulates temperature, and prevents water loss.
Negative feedback reverses a change to maintain homeostasis.
Positive feedback amplifies a change, often to complete a process like blood clotting.
The lymphatic system returns fluid to blood and helps defend against infection.
The endocrine system secretes hormones to regulate body functions.
A tissue is a group of similar cells; an organ is made of tissues working together.
The reproductive system produces offspring and sex hormones.
