10 The Internally Integrated Human Animal
10.1 The Integrated Human
[x] List the names of 10 body systems and the principle role of each in serving the rest of the
body.
1. Muscular system: facilitate movement of the body and within the body
2. Skeletal system: gives support and form to the body/ support muscular system
3. Cardiovascular system: facilitate movement of cells and soluble materials throughout
the body
4. Respiratory system: enables critical gaseous reactants and products to be added to
and removed from the blood.
5. Integumentary system: skin / insulate & protection from desiccation(removal of
mositure) and invasion of foreign pathogens
6. Nervous system: coordination of organism activities and signal sending
7. Endocrine system: create hormones that control many aspects of the body's form
and function
8. Urinary system: Filters the blood / stores urine for excretion
9. Lymphatic system: surveys tissue fluids and their movement back to the bloodstream
10. Digestive system: facilitates intake, mechanical & enzymatic breakdown of foods /
absorption of nutirents and removing wastes
[x]A student runs up a flight of stairs. Other than the skeletal system, which body system
would be most immediate in its support of the muscular system in this activity?
• Cardiovascular and respiratory systems
, [x] As a student runs up a flight of stairs, her system serves her by providing
moisture for evaporation to remove the heat her body is generating. It helps to moderate
her body temperature.
• Integumentary
10.2 The
Muscular
System Muscle
Structural
Organization
[x]A muscle is composed of thousands of muscle cells (fibers) bound into groups of 100 or
more fibers call each of which is surrounded by tissue called
perimysium.
• Fascicles, connective
[x] What is the name of a contractile unit of a muscle?
• Sacromeres
