DEVELOPMENTAL ANATOMY
From conception to death
Gross anatomy
CLINICAL ANATOMY
Medical specialties
Microscopic anatomy
Examines cells and molecules
Cytology
Study of cells and their structures
cyt=cell
Histology
Study of tissues and their structures
The chemical (or molecular) level
Atoms are the smallest chemical units
Molecules are a group of atoms working together
The cellular level
Cells are a group of atoms, molecules, and organelles working together
The tissue level
A groups of similar cells working together
The organ level
A group of different tissues working together
The organ system level
A group of organs working together
Humans have 11 organ systems
The organism level
A human is an organism
Integumentary system

Muscular system
ORGANS
Skeletal muscle and associated tendons
Muscular system
FUNCTIONS
Provides movement
Provides protection and support
Generates heat to maintain body temp
Nervous system
ORGANS
Brain

Nervous system
FUNCTIONS
Directs immediate response to stimuli
Coordinates and moderates activities of other organ systems
Provides and interprets sensory information about external conditions
Endocrine system
ORGANS
Pituitary gland Thyroid gland Pancreas Suprarenal gland Gonads Endocrine tissues in other systems
Endocrine system
FUNCTIONS
Directs long term changes in other organ systems
Adjust metabolic activity and energy use
Controls many structural and functional changes during development
Cardiovascular system
ORGANS
Heart
Blood
Blood vessels
Cardiovascular system
FUNCTIONS
Distributes heat in control of body temp
Distributes blood cells, water, and dissolved materials (nutrients, waste products, oxygen, and carbon dioxide
Lymphoid system
ORGANS
Spleen Thymus Lymphatic vessels Lymph nodes Tonsils
Lymphoid system
FUNCTIONS
Defends against infection and disease
Returns fluids to bloodstream
Respiratory system
ORGANS
Nasal cavities Sinuses Larynx Trachea Bronchi Lungs Alveoli
Respiratory system
FUNCTIONS
Delivers air to alveoli(gas exchange)
Oxygen to bloodstream

FUNCTIONS
Processes and digests food
Absorbs and conserves water
Absorbs nutrients
Stores energy reserves
Urinary system
ORGANS
Kidneys
Ureters
Urinary bladder
Urethra
Urinary system
FUNCTIONS
Excretes waste products from the blood
Controls water balance by urine produced
Stores urine prior to voluntary elimination
Regulates blood ion and pH
Male reproductive system
ORGANS
Testes Epididymides Ductus deferens Seminal vesicles Prostate gland Penis Scrotum
Male reproductive system
FUNCTIONS
Produce male sex cells, suspending fluids, and hormones
Sexual intercourse
Female reproductive system
ORGANS
Ovaries Uterine tubes Uterus Vagina Labia Clitoris Mammary gland
Female reproductive system
FUNCTIONS
Produce female sex cells, and hormones
Supports developing embryo

Homeostasis
All body systems working together to maintain a stable internal environment regardless of conditions outside the body
Normal range (of the body)
Temp: 37C
Blood glucose: 0.1%
pH: 7.4
Blood pressure: 120/80
Autoregulation (intrinsic)
Automatic response in a cell, tissue, or organ to some environmental change
Extrinsic regulation
Responses controlled by nervous and endocrine systems
Receptor
Receives the stimulus
Control center
Processes the signal and sends instructions
Effector
Carries out instructions
Negative feedback
The response of the effector negates the stimulus
BODY IS BROUGHT BACK TO HOMEOSTASIS
Positive feedback
The response of the effector increase change in stimulus
BODY IS MOVED AWAY FROM HOMEOSTASIS
