Transcript ANATOMY AND PHYSIOLOGY

The Systems of the Human Body
• Can you guess how many different system
make up the Human Body?
• Well….the correct number is 11!! 11
different systems all working together for
you to function.
• How many do you know out of those 11?
• We will go over all 11 in today’s lecture!
Levels of Organization
• Lets review…What are the levels of
organization within a single human body??
• Atoms/Molecules
• Cells
• Tissues
• Organs
• Systems
• Organisms/Individual
Integumentary System
Integumentary System
Integumentary System
• Skin, hair, nails,
sweat glands,
and sebaceous
glands.
• Protect
underlying
tissue, help
regulate temp,
sensory
receptors, and
synthesize
certain products.
Integumentary System
•Bones,
ligaments,
tendons, and
cartilage.
• Provides frameworks,
protective shield for
softer tissue,
attachment for muscles,
and act together with
muscles for movement
• Tissue within the bones
produce blood cells,
store inorganic salts.
MUSCULAR SYSTEM
MUSCULAR SYSTEM
• All muscles…
Smooth,
cardiac, and
skeletal..
• Force for body
movement, help
maintain posture, are
the main source of
body heat.
• Aids in circulation of
blood and food
throughout the body.
NERVOUS SYSTEM
NERVOUS SYSTEM
• Brain, spinal cord,
nerves, and sense
organs.
• Nerve cells send
nerve impulses
• Specialized sensory
receptors.
• Some nerves
receive/send impulses
• Some carry impulses
from the brain or
spinal cord to muscles
NERVOUS SYSTEM
• The basic unit of the
nervous system are
neurons.
• There are 3 types:
sensory, motor, and
interneurons!
ENDORCRINE SYSTEM
ENDORCRINE SYSTEM
• Function: Controls
growth, development,
and metabolism.
• Maintains
Homeostasis
• ORGANSPituitary, thyroid,
parathyroid, and
adrenal glands,
pancreas, ovaries,
testes, pineal gland,
and thymus gland
CARDIOVASCULAR SYSTEM
CIRCULATORY SYSTEM
• Includes heart,
arteries, veins,
capillaries, and blood
• Heart-pump that
forces blood through
blood vessels.
• Blood- carries oxygen
from lungs and
nutrients from
digestive organs to all
body cells
CIRCULATORY SYSTEM
• These are red blood cells!
• They are the most numerous
cells in the body.
• These cells transport oxygen.
• The cells actually have no
nuclei.
• They live in the human body
for about 120 days!
• Heart-pump that
forces blood through
blood vessels.
• Blood- carries oxygen
from lungs and
nutrients from
digestive organs to all
body cells
Lymphatic/Immune
System
Lymphatic/Immune
System
• Function: Helps to
protect the body
from disease
• Collects fluid lost
from blood vessels
& returns the fluid
to the circulatory
system.
• Structures: White
blood cells, thymus,
lymph nodes, lymph
vessels
Digestive System
Digestive System
• Includes: Mouth, tongue, teeth,
salivary
.
glands, pharynx, esophagus, stomach, liver,
gallbladder, pancreas, small and large intestine
• Breaks down food to similar forms that can
pass through cell membranes to be absorbed.
Digestive System
• Materials not
absorbed are
transported back
outside the body.
(Primarily the job of
your colon)
• Certain digestive
organs produced
hormones and
function as part of
the endocrine
system.
The Respiratory System
The Respiratory System
• Includes: Nasal
cavity, pharynx,
larynx, trachea,
bronchi, and
lungs
• Function: Takes air in
and out and
exchanges gases
between blood and
the air. (O2 in and
CO2 out )
Excretory/Urinary
System
Urinary System
Excretory/Urinary
System
• Primarily includes
kidney, ureters,
urinary bladder, and
uretha
• Some resources
include lungs & skin
• Kidneys remove
wastes from blood and
assist in maintaining
the body’s water and
electrolyte balance
• Product is urine
Reproductive System
Reproductive System
Female
• Ovaries, uterine tubes,
uterus, vagina, clitoris,
vulva
• Function: Produce and
maintain egg cells, receive
sperm cells, support
development of an
embryo and function in
birth process
Reproductive System
Male
• Scrotum, testes,
epididymides, vasa
deferentia, seminal
vesicles, prostate gland,
bulbourethral glands,
urethra, and penis
• Function: Produce and
maintain sperm cells,
transfer sperm cells into
female reproductive
organs.
