Body Systems Overview II
The Inner Tube:
Blood ‘n Guts
(Bio 34: Anatomy and Physiology II)
Larry Frolich, Body Systems
Circulatory System
• Function: Circulate blood
throughout body; Deliver and
take away nutrients, oxygen,
carbon dioxide, immune cells,
hormones
• Structures: Heart, Blood
Vessels
• Tissues: Muscle, Connective
Tissues, Endothelial lining,
Blood
• How’s it work? Heart pumps
blood which carries cells,
diffused substances

Lymphatic/Immune System
• Function: Provide immunity
and immune cell movement;
Take up interstitial fluid;
subsidiary of circulatory
system
• Structures: Lymphatic
Vessels; Blood cell forming
organs
• Tissues: Blood, Connective
Tissues, Endothelial lining
• How’s it work? Open-ended
lymph capillaries give access
to interstitial spaces;
Movement of blood vessels
moves lymph through tubes

Respiratory System
• Function: Exchange of oxygen
and carbon dioxide between
air and blood
• Structures: Lungs,
Respiratory tree (bronchial
tubes, pharynx, larynx, nasal
region, alveoli), Diaphragm
• Tissues: Connective Tissues,
Epithelial lining of respiratory
tract, muscle
• How’s it work? Diaphragm
inflates lungs, air moves in and
oxygen/carbon dioxide diffuse
into blood at capillaries in
alveoli; tightly allied with
circulatory system

Digestive System
• Function: Digest Food and
absorption of breakdown
products into blood
• Structures: Mouth,
Esophagus, Stomach,
Intestines, Liver, Pancreas,
Rectum, Anus
• Tissues: Muscle, Connective,
Epithelial lining, Glandular
• How’s it work? Food taken in,
processed mechanically and
chemically, breakdown
products absorbed across wall
into bloodstream; indigestible
roughage accumulated and
defecated from body

Urinary System
• Function: Concentrate and
secrete nitrogenous waste
from body
• Structures: Kidneys, Ureter,
Bladder, Urethra
• Tissues: Kidney tissue, smooth
muscle, transitional epithelium
• How’s it work? Kidneys
concentrate nitrogenous waste
from blood forming urine which
is collected through ureter into
bladder and excreted via
urethra

Reproductive System—Female
• Function: Produce
subsequent generation
(provide egg for female
genetic contribution to embryo,
pregnancy, lactation)
• Structures: Ovaries, Uterus,
Fallopian tube; Vagina,
Mammary glands
• Tissues: Muscle, Connective,
Epithelial lining, Glandular
• How’s it work? Eggs produced
in ovary, fertilized by sperm
following ovulation, copulation,
embryo gestated in uterus,
birth through vagina, lactation
from mammary glands

Larry Frolich, Body Systems
Reproductive System--male
• Function: Produce
subsequent generation
(provide sperm for male
genetic contribution to embryo)
• Structures: Testes, vas
deferens, penis, prostrate and
other glands, urethra
• Tissues: Muscle, Connective,
Spongy, Epithelial lining,
Glandular
• How’s it work? Sperm
produced by testes, carried to
urethra through vas deferens,
semen produced by prostrate,
joins sperm and ejaculated
from body through penis
