understanding what we are Flashcards
(16 cards)
what is anatomy?
Anatomy: is the study of body parts and their relationships to one another. Three components of anatomy are gross (macroscopic), Microscopic, and developmental.
what is physiology?
the study of the function of the body’s structural machinery
what is gross anatomy (macroscopic)
regional: all structures in one part of the body
systemic: gross anatomy of the body studied by system
surface: study of internal structures at they relate to the overlying skin
What are the six components of The Hierarchy of yourself
- chemical: atoms combine to form molecules
- Cellular: cells are made of molecules
- Tissue: consists of similar types of cells
- Organ: made up of different types of tissues
- organ system: consists of different organs that work closely together
- Organism: made up of the organ systems
Integumentary system structures and functions
structures: skin, hair, sweat and oil glands
functions: forms external body covering
- protects deeper tissues from injury
- involved in vitamin d synthesis
- prevents desiccation, heat loss, and pathogen entry
- site of pain and pressure receptors
Skeletal system structures and functions
structures: 206 bones of the human body
functions: protects and supports organs
- provides a framework that muscles can use to create movement
- hematopoiesis (synthesis of blood cells)
-mineral storage, bones contain 99% of the body’s calcium
Muscular system structures and functions
structures: the 600+ muscles of the body
functions: locomotion
- manipulation of the environment
- maintaining posture
- thermogenesis (generation of heat)
Nervous system structures and functions
Structures: brain, spinal cord & nerves
functions: fast action control system of body
monitors the internal & external environment and then responds if necessary
Endocrine system structures and functions
structure: hormone secreting glands: pituitary, thyroid, thymus, pineal, intestine, stomach, testes, ovaries, kidneys and heart
functions: long term control system of the body
regulates growth, reproduction, and nutrient use among other things.
Hematologic system structures and functions
Structures: blood and its components (red blood cells, white, platelets)
function: transports nutrients/gases
fights infection and clots blood to prevent hemorrhage
Cardiac & Vascular systems structures and functions
structures: heart, blood vessels (arteries, veins, and capillaries)
functions: the heart pumps blood thru the blood vessels
maintains blood pressure
Lymphatic & immune system structures and functions
structures: lymphatic vessels, lymph nodes, spleen, thymus, red bone marrow
functions: returns leaked fluid back to the bloodstream
disposal of debris and attacking &resisting forgiven invaders
Digestive system structures and functions
structures: organ cavity, esophagus, stomach, small/large intestine, rectum, salivary glands, pancreas, liver, gallbladder
functions: ingestion and breakdown of food into absorbable units that will enter the blood for distribution to the body’s cells
Respiratory system structures and functions
structures: nose cavity, pharynx, trachea, bronchi, lungs
functions: constantly supplied blood with O2 and removes CO2 and regulates blood pH
Urinary system structures and function
structures: kidneys, ureters, urinary bladder, urethra
functions: removal of water-soluble wastes
regulation of body’s levels of water, electrolytes & acidity
Reproductive system structures and function
structures:
-female: ovary, Fallopian tube, uterus, cervix, vagina, mammary glands
Male: testes, scrotum, epididymis, vas deferens, urethra, protest gland, penis
Function: production of offspring
