ch 35&36 (nervous, muscular, skeletal, & Integumentary systems) Flashcards
what is the function of the nervous system?
controls and coordinates the body’s response to changes in its internal and external environments
what structures make up the nervous system?
brain, spinal cord, peripheral nerves
what structures make up the integumentary system?
skin, hair, nails, sweat and oil glands
what is the function of the integumentary system?
serves as a barrier against infection and injury; helps to regulate body temperature; provides protection against UV light from the sun
what structures make up the respiratory system?
nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs
What is the function of the respiratory system?
provides the oxygen needed for cellular respiration and removes excess carbon dioxide from the body
what structures make up the digestive system?
mouth, pharynx, esophagus, stomach, small and large intestines, rectum
what is the function of the digestive system?
converts foods into simpler molecules that can be used by the cells of the body; absorbs food; eliminates waste
what structures make up the excretory system?
skin, lungs, kidneys, ureters, urinary bladder, urethra
what is the function of the excretory system?
eliminates waste products from the body
what structures make up the skeletal system?
bones, cartilage, ligaments, tendons
what is the function of the skeletal system?
supports the body; protects internal organs; allows movement; stores mineral reserves; provides a site for blood cell formation
what structures make up the muscular system?
skeletal muscle,smooth muscle, cardiac muscle
what is the function of the muscular system?
muscles are able to contract to move different part of the body
what structures make up the circulatory system?
heart, blood vessels, blood
what is the function of the circulatory system?
brings oxygen, nutrients, and hormones to cells; fights infection; removes cell wastes; helps to regulate body temperature
what structures make up the endocrine system?
hypothalamus, pituitary, thyroid, parathryoids, adrenals, pancreas, ovaries, testes
what is the function of the endocrine system?
controls growth development, and metabolism; maintains homeostasis
what is the function of the reproductive system?
produces reproductive cells; in females, nurtures and protects developing embryo
what structures make up the lymphatic/immune systems?
white blood cells, thymus, spleen, lymph nodes, lymph vessels
epithelial tissue
covers the surface of the body and lines internal organs
connective tissue
holds organs in place and binds different parts of the body together
nervous tissue
receives and analyzes messages from inside and outside the body
muscle tissue
controls internal movement of materials and external movement of the body
homeostasis
maintaing a controlled, and stable internal environment
feedback inhibition/negative feedback
the process in which a stimulus produces a response that opposes the original stimulus
what are the levels of the organization
atom, molecule or compound, organelle, cell, tissue, organ, organ system, organism
tissue
a group of cells that perform the same function
dermis
inner layer of the skin
epidermis
outer layer of the skin
keratin
though,fibrous protein found in skin
melanin
dark brown pigment found in skin that helps protect the skin from damage by absorbing UV rays from the sun
what are the hair and nails made from
keratin
cardiac muscle
- found only in the heart
- involuntary (works without conscious control)
smooth muscle
- found in t stomach, blood vessels, and intestines
- usually involuntary
- most can function without nervous stimulation
skeletal muscle
- usually attached to bone
- voluntary movement
what are the 3 types of muscle
smooth, cardiac, skeletal
ligaments
connect bone to bone
