SALADO WITH CORRECT
SOLUTIONS
Principle of Complementarity - ANSWER-The function of the body reflects the
anatomical structures
Levels of Organization that make up the human body - ANSWER-1. Chemical
2. Cellular
3. Tissue
4. Organ
5. Organ System
6. Organismal
Chemical - ANSWER-Atoms combine to form molecules
Cellular - ANSWER-Cells are made of molecules
Tissue - ANSWER-Consist of similar types of cells with a common function
Organ - ANSWER-Made up of different types of tissue
Organ System - ANSWER-Different organs that work together
Organismal - ANSWER-The human is made up of different types of organ systems
Nervous system - ANSWER-control system of the body- responds to external and
internal changes by activating the right muscles and glands.
Endocrine system - ANSWER-secretes hormones that regulate growth process and
nutrient usage by body cells.
Cardiovascular system - ANSWER-pumps blood; blood vessels transport blood
which contains carbon dioxide, nutrients, waste, etc.
Lymphatic system - ANSWER-Immunity; picks up fluid leaked from blood vessels
and returns it to the blood, disposes of debri in the lymphatic vessels, houses white
blood cells (lymphocytes) for immunity.
Respiratory system - ANSWER-Keeps blood constantly oxygenated and removes
carbon dioxide, and gaseous exchanges occur in the walls of air sacs within the
lungs.
List the 11 organ systems - ANSWER-Integumentary system, Skeletal system,
Muscular system, Nervous System, Endocrine system, Cardiovascular system,
, Lymphatic system/immunity, Respiratory system, Digestive system, Urinary system,
Male/Female Reproductive system
Integumentary system - ANSWER-Hair, skin and nails. Sweat and oil glands.
Synthesizes vitamin D. Protects deeper tissues from damage. Site of cutaneous
receptors (pain, pressure, etc).
Skeletal system - ANSWER-Protects and supports body organs, stores minerals,
provides a framework for muscles to use for movements, and blood cells are formed
within bone.
Muscular System - ANSWER-Allows manipulation of the environment, locomotion,
facial expression, and produces heat.
Digestive System - ANSWER-Breaks down food into absorbable units that enter the
blood for distribution to body cells.
Urinary System - ANSWER-Eliminates nitrogenous waste from body; regulates
water, electrolyte and acid-base balance of the blood.
Reproductive System - ANSWER-Production of offspring
Positive Feedback mechanisms - ANSWER-Positive feedback is when a system
tends to increase output. The product of a reaction influences or increases the
forward direction of the system: in positive feedback systems the presence of a
product (or signal) results in an increase in the production (amplification) of that
product (or signal).
Positive feedback example:
One common example of positive feedback is the network effect, where more
people are encouraged to join a network the larger that network becomes. The result
is that the network grows more and more quickly over time.
Negative feedback mechanisms - ANSWER-Negative feedback is when a system
tends to reduce output or the product prevent the reaction from continuing: negative
feedback (or feedback inhibition) systems, where the presence of a product of the
system results in a decrease in the production of that product.
Negative feedback example:
* Neurons in the hypothalamus secrete thyroid releasing hormone (TRH), which
stimulates cells in the anterior pituitary to secrete thyroid-stimulating hormone (TSH).
* TSH binds to receptors on epithelial cells in the thyroid gland, stimulating synthesis
and secretion of thyroid hormones, which affect probably all cells in the body.
* When blood concentrations of thyroid hormones increase above a certain
threshold, TRH-secreting neurons in the hypothalamus are inhibited and stop
secreting TRH. This is an example of "negative feedback".
Example of homeostatic imbalance - ANSWER-Disease
Anatomy - ANSWER-Study of the structure of the human body
