A state of dynamic equilibrium in which the internal environment of the body remains relatively constant
What is Anatomy?
Anatomy is the structure of the body, location, appearance in relation to other body parts
what is Physiology
Physiology is the study of the body’s function or how it works
What is anatomy and physiology in relation to eachother
structure vs function
what are the 5 basic functions
What is the function of the Nervous system
how does the nervous system communicate
through an electrical Impulse or nerve impulse that works fast to maintain short term homeostasis
How does the nervous system maintain homeostasis
Receives, interprets and responds to sensations in order to maintain homeostasis.
Monitors and controls body activities
What organs are in the nervous system
sense organs (Nose, ear,eyes, tongue,etc..)
what is the process of the nervous system
What does PNS stand for? what does it do?
Peripheral Nervous System is the nervous link. parts of your PNS are controlled by the brain automatically. This is the autonomic nervous system. It manages some things your body does 'without thinking' such as reactions
what does CNS stand for? what does it do?
Central Nervous System
Combines pieces of Information and makes decisions
what specialist deals with the nervous system
what happens if the nervous system fails
If something happens to the organs within the system there can be no communication between the brain and the body. So essentially the victim will become a vegetable and have no control over their body. Ex. Paraplegia- Complete paralysis of the lower half of the body including both legs, usually caused by damage to the spinal cord.
what system is this?
the nervous system
What are the differences between the nervous and endocrine system
Nervous System:Fast Impulse,Short term Homeostasis,Electromagnetic Impulse
Endocrine System:Slower Chemical Messenger,Long term Homeostasis, Hormones
What is the basic function of the endocrine system?
How does the Endocrine system communicate
Ductless Glands that secrete hormones.Communicates through hormones (Chemical Messengers) that are secreted and travel into the blood stream towards the target organ. Hormones work slower than an impulse to maintain long term Homeostasis.
what are the organs in the endocrine system
what is the specialist that deals with the endocrine system
what happens if the endocrine system fails
If the Endocrine system is damaged or does not work properly the body might not grow or mature properly. All body functions would be deranged and death would occur. Too much or too little of any hormone can be harmful to your body. For example, if the pituitary gland produces too much growth hormone, a teen may grow excessively tall. If it produces too little, a teen may be unusually short.
What system is this?
what is the function of the reproductive system?
Procreation (Survival of species does not play a role in homeostasis)
what specialists deal with the reproductive system
Male:Urologist, Fertility specialist
what would happen if the reproductive system is damaged?
If there is damage to the reproductive system the victim will most likely never be able to reproduce.
What are the functions of the cardiovascular system
How does the cardiovascular transport
Moves blood to all body systems so that every cell can obtain oxygen and nutrients needed to carry on metabolic activities. Wastes produced are then moved to organs for processing before their accumulation causes damage.
How does the cardiovascular system exchange
Capillaries provide a “Drop off” and “Pick up” service to cells. Is the dropping off of gases and nutrients, and the picking up of wastes, occurring between the blood plasma and ISF.
what are the organs in the cardiovascular system
what are the three subcategories of blood vessels
What do the arteries do
carry oxygenated blood away from the heart
what do the veins do
carry deoxygenated blood towards the heart
what is the purpose of the capillaries
they serve as a site of exchange, they provide a “Drop off” and “Pick up” service to cells. Is the dropping off of gases and nutrients, and the picking up of wastes, occurring between the blood plasma and ISF.
what specialist deals withe the cardiovascular system
what happens if the cardiovascular system fails
If the cardiovascular system fails the blood will not be pumped to muscles. Blood contains oxygen and glucose, which the cells need to convert to energy and to survive, and if the cells do not get blood, they will die, and the person whose system has failed will die. This is why the circulatory system is vital for life.
What are the functions of the lymphatic system
how does the lymphatic system protect
Defends the body from the harmful effects of microorganisms, toxins, and dead or diseased body cells.
How does the lymphatic system transport
Transports/returns fluid into the bloodstream to help maintain fluid balance
What organs deal with the lymphatic system
What specialist deals with the lymphatic system
what would happen if the lymphatic system failed
The lymphatic system is the body's sewer system. Waste products and infectious material will end up in this circulatory system which eventually empties back into the blood system and to the entire body. Infections would not be fought off and life could not be sustained.
what are the fluids in the lymphatic system
ISF (Interstitial pace)
where is lymph fluid located
in the lymphatic vessels
where is plasma fluid located
in the blood vessels
where is ISF fluid located
in tissue cells
where is CSF fluid located
in the central nervous system (around brain and spinal chord)
what system is this?
the lymphatic system
what are the functions of the skeletal system
how does the skeletal system support
strong, rigid nature enables it to serve as structural frame that supports the other body structure
how does the skeletal system protect
bones physically surround internal organs and their hard quality provides a shield against damage.
how does the skeletal system create movement
attachment sites for skeletal muscles enabling a coordinated movement. Rigid nature allows them to serve as levers for skeletal muscles to pull on during contraction
how does the skeletal system produce
Red marrow within spongy bone manufactures blood cells/formed elements from stem cells.
how does the skeletal system storage
reservoir for two main minerals(Calcium and Phosphate) These minerals (Electrolytes) are needed for many reasons
what organs are in the skeletal system
what specialist deals with the skeletal system
what would happen if the skeletal system fails
If the skeletal system fails you would die a few seconds later, after your body crushes its own vital organs- and by that time, your body would look like a deflated balloon with hair attached to it.
what are the functions of the muscular system
how does the muscular system provide movement
Each motion relies on the integrated function, bones, joints, nerves and skeletal muscles. Contraction occurs shortens muscle cells to pull on bones causing movement
how does the muscular system support
rigid connection between skeletal muscles and bones help hold body in upright position and strengthens skeletal frame.
how does the muscular system produce
heat is a by-product of movement.Helps maintains normal body temperature.
describe the three types of muscle tissue
Smooth- Found in hollow organs
Skeletal- Muscle that is firmly attached to bone
Cardiac- Within myocardium of heart
what specialist deals with the muscular system
a physical therapist
what organs are in the muscular system
what would happen if the muscular system failed
If the muscular system fails you cannot move. Muscular dystrophy is a name for certain types of diseases.The disorders weaken skeletal muscles. Therefore, muscular dystrophies seriously affect movement, posture, and breathing. Skeletal deformities are often associated with this group of diseases.
what are the functions of the respiratory system
how does the respiratory system exchange
Exchange of gases between the environment and blood stream
how does the respiratory system excrete
Removes metabolic waste such as carbon dioxide and water vapor
how does the respiratory system regulate
Maintains body temperature by increasing or decreasing the amount of war air released. Maintain Ph. of body fluids by removing carbon dioxide made during cell respiration
what organs are in the respiratory system
what specialists deal with the respiratory system
what is the structural organization of the respiratory system
Alveoli of lungs
what would happen if the respiratory system failed
without oxygen the body will cease to survive, as there is a no oxygen entering the body, the heart rate increases (tries to beat quicker in a bid to get more oxygen) and eventually life will be over as the brain cannot survive for more than a few minutes (dependent on individual) without oxygen.
what are the functions of the integumentary system
how does the integumentary system regulate
Maintains body temperature by causing blood vessels near skin to vasodilate or vasoconstrict. Maintains body temperature by increasing or decreasing the amount of water released during the sweating mechanism
how does the integumentary system produce
Vitamin D is produced by the skin when exposed to UV light. Vitamin D helps absorption of calcium from food. Calcium is needed for bone growth/ repair, muscle contraction, impulses
how does the integumentary system communicate
sensory receptors located within the skin react to stimuli and relay this information to the CNS
how does the integumentary system protect
physical barrier formed by skin protects against: loss of body fluids, physical injury, ultraviolet light,invasion of microorganisms
How does the integumentary system excrete
sweat glands release small amounts of metabolic waste through tiny pores to the outside of the body
what are the organs in the integumentary system
what specialist deals with the integumentary system
what would happen if the integumentary system failed
Sweat is a part of homeostasis and when this layer doesn't exist you cannot excrete sweat. Therefore, you could not use this as a way to cool off. Without the skin, hair, and nails then viruses and bacteria could just get into your body easily! If there was no integumentary system or it failed rocks, and other unwanted objects could get into your body.
what is the structural organization of the integumentary system
(Hair, sweat glands, sebaceous glands)
what are the functions of the urinary system
how does the urinary system excrete
Removes metabolic wastes such as: nitrogen waste, water electrolytes and toxins
how does the urinary system regulate
Maintains proper levels of blood composition, water electrolytes, PH and maintains blood pressure
how does the urinary system storage
temporarily holds urine until the "right time”
how does the urinary system reabsobe
moving needed substances back into theblood stream so they are not excreted
how does the urinary system filtrate
separates large from small molecules
what organs are in the urinary system
what specialists deal with the urinary system
a Nephrologist or a Urologist
what happens if the urinary system fails
depends on how bad it is, but basically if your kidneys don’t function properly your body will retain water. and your liver amongst other things cannot get rid of toxins. If it is where a person doesn’t urinate then dialysis will be needed immediately or the immune system will eventually breakdown and lead to other complications.
what are the functions of the digestive system
how does the digestive system excrete
