E1P1: overview of the ten human organ systems

Are systems group similarly to anatomy?

• why or why not?

no

• because in physiology its based on FUCTIONAL systems instead of structural

Will we study the muscular and skeletal system separately or together?

• why or why not?

Together

• because the author chose to and because they are so dependent upon the function of each other

How is the lymphatic system considered in anatomy? How about physiology?

considered to be an anatomical system

in physiology are considered to function as PART/component of three systems

What three systems does the lymphatic system function as a part of? c.d.i

• how?

circulatory: returning excess fluid and escaped proteins from interstitial space to the plasma

digestive: transporting fats from the intestine to the circulation

immune: lymph nodes contain clusters of immune cells

How are organ systems often in nature, how do they operate?

organ systems are often redundant (share functions) in nature, operating as integrated units

Example of redundancy in systems

every system plays some role in immunity

Example of integration in systems

to regulate calcium concentration, the endocrine system acts on bones, kidneys, and intestines to ensure plasma calcium concentrations remain within a certain range

What are the ten systems we will study?

circulatory, endocrine, nervous, respiratory, urinary, digestive, immune, integumentary, musculoskeletal, and reproductive

What 5/10 system will we study in more detail?

circulatory, endocrine, nervous, respiratory, and urinary

What 5/10 system will we study in less detail?

digestive, immune, integumentary, musculoskeletal, and reproductive

Circulatory

• components

• functions

heart, blood, and blood vessels

transport materials between all cells of the body, protection, temperature regulations

Endocrine

• components

• functions

various glands and endocrine cells

coordinates body functions through the synthesis and release of regulatory molecules. (maintaining homeostasis)

Nervous

• components

• functions

brain, spinal cord, and nerves

coordinates function through electrical signals and release of regulatory molecules (maintains homeostasis)

Respiratory

• components

• functions

lungs and airways

functions to exchange oxygen and carbon dioxide between the external and internal environments. vocalization and immunity

• maintains the acid-base balance

Urinary

• components

• functions

kidneys, bladder

functions to maintain the internal environment by regulating water and solute balance as well as removing wastes and producing hormones

• acid-base balance

Digestive

• components

• functions

consists of the GI tract and accessory organs

process food for energy and nutrient uptake, moving them, water, and electrolytes from external to internal environments

Immune

• components

• functions

lymphatic tissue and parts of integumentary and circulatory systems, a multifactorial system

protects against foreign invaders

Integumentary

• components

• functions

skin, hair, nails, and glands

protection from the external environment, reduced dehydration, UV light, sensation, excretion of substances, immunity, synthesis of Vitamin D, and body temperature

Musculoskeletal

• components

• functions

bones and skeletal muscles

protection, support, and movement; mineral storage, heat generation

Reproductive

• components

• functions

gonads and accessory structures that produce necessary gametes for reproduction

functions to perpetuate the species
