study of structure and shape of the body and its parts and their relationships to one another
study of how the body and its parts work
The levels of structural organization is...
atoms, cells, tissue, organs, organ systems, organism
Integumentary system is...
- -external body covering
- - location of pain, pressure, receptors, sweat/oil glands etc.
- - waterproofs the body and protects inside from injury
- - regulates body temperature
Skeletal System is...
- -consists of bone and cartilidge
- - supports the body
- - provides a base for the muscles to move
- - creates blood cells
Muscular System is...
- contract or shorten
Nervous System is...
- - body's control system
- - consists of brain, spinal cord, nerves, and sensory receptors
- - responds to stimuli inside and outside of body (temp. light, sound outside) ( decrease in oxygen, stretching of tissue inside)
Endocrine System is...
- - controls body's activites
- - produces hormones
- - Examples: pituitary, thyroid, adrenals, and thymus gland
Cardiovascular System is...
- - primary organs are heart and blood vessels
- - carries oxygen and other nutrients to other parts of the body
- - pumps blood to other parts of the body
Lymphatic System is...
- - includes, lymph vessels, lymph nodes, spleen, tonsils etc.
- - returns leaked fluid back into the body
- - help clean the blood and fights bacteria
Respiratory System is...
- -keep the body constantly supplied with oxygen and remove CO2
- - consists of nose, pharync, larynx, trachea, bronchi, and lungs
Digestive System is...
- -breaks food down so it can be absorbed
- - indigestible food expelled out
- -pathway of food from mouth to anus
Urinary System is...
- -eliminates liquid wastes
- -regulates water, electrolytes, and acid-balance in the blood
Male/Female Reproductive System is...
- - produce offspring
- - testes: sperm ovaries:eggs
- - breasts produce milk
1.) Necessary Life Functions are..
- - Maintaining boundries ( allowing protection like skin or membrane)
- - Movement (activities promoted by muscular system)
- - Responsiveness (ability to sense and react to stimuli)
- - Digestion (breaking down and using food for blood)
2.) Necessary Life Functions are..
- - Metabolism (chemical reactions within the body)
- - Excretion (expelling waste)
- - Reproduction (creating offspring)
- - Growth (increase in size)
- Toward the head
- - The forehead is superior to the nose
- Away from the head
- - The navel is inferior to the breastbone
- in front of
- - the breastbone is anterior to the spine
- - the spine is posterior to the spine
- on the inner side
- - the heart is medial to the arm
- on the outer side
- - the arm is lateral to the chest
- close to the attachment point
- - the arm is proximal to the wrist
- (closer to the a shoulder joint connecting the whole arm)
- Farther from the attachment point
- - the knee is distal to the thigh
- Toward the body surface
- - the skin is superficial to the skeleton
- Away from the surface
- - lungs are deep to the rib cage
