Structure of human body Flashcards
Learn dumbass
Name the 6 levels of structural organization of the human body
Chemical, Cellular, Tissue, Organ, Organ system level, Organism
Name the 11 systems of the human body
Integumentary, Muscular, Skeletal, Nervous, Endocrine, Lymphatic and immune, Cardiovascular, Respiratory, Digestive, Urinary, and Reproductive
Give an example of an Organ that belongs to more than one system, and name those systems.
Pancreas: Endocrine and digestive system
Name the 3 main layers of the Integumentary system
Epidermis, Dermis, Hypodermis
Describe the 2 main functions of the Epidermis
First barrier of protection from invading substances.
Retains moisture to keep the skin hydrated.
Name the 2 layers of the dermis
Reticular, Papillary
What does the bottom layer of the dermis contain
Blood vessels, Glands, Hair follicles, Lymphatics, nerves, and fat cells.
Describe the structure and link the structure to determine the function of the bottom layer of the dermis
Net-like structure of Elastin and Collagen fibers. These fibers support the skin structure and allow movement and elasticity.
What does the top layer of the dermis contain
Fibroblast, Triglycerides, Blood vessels, nerves, touch receptors, and phagocytes
Describe the structure and link the structure to determine the function of the top layer of the dermis
Much thinner than the bottom layer of the dermis, the top layer extends to the basement layer of the epidermis. Forming a strong bind that connects like interlocking fingers.
State the 4 functions of the Hypodermis
Storing energy ( Triglycerides), Connecting the reticular layer to bones and muscles, insulating your body, and protecting the body from harm
What 3 muscle groups are involved in the muscular system
Skeletal, Axial, Appendicular
What are the functions of the skeletal muscles?
Movement, sustaining body posture and positioning, maintaining body temperature, storing nutrients, and stabilizing joints
Give examples of skeletal muscles
Deltoids, abdominals, hamstrings
What are the functions of Axial muscles?
Provide posture and support to the axial skeleton
