Unit 3 Flashcards
Skeletal
Bones, tendons, ligaments, cartilages
Functions: support, protection, movement, calcium storage, hematopoiesis
Nervous
Brain, spinal cord, nerves
Functions: coordination of body parts; information processing
Digestive
Oral cavity, pharynx, esophagus, stomach, small and large intestines, salivary glands, liver, pancreas, gall bladder
Functions: breakdown of food into substances that can be absorbed for energy
Four major types of tissues
Epithelial, connective, cardiac, muscle
Skeletal system roles
Gives body its shape
Protects fragile organs
Allows for movement
Stores calcium
Helps create blood cells
Lymphatic
Bone marrow, lymph nodes, thymus, spleen
Functions: prevents disease, immunity, contains lymphocytes. Transport fluid from tissues back to bloodstream
Three types of muscle tissue
Cardiac, smooth, skeletal
Integumentary
Major organs: skin, hair, nails, sweat glands, sebaceous glands
Functions: protection, regulation of body temperature, synthesis of vitamin D
Six major types of joints
Ball and socket
Condylar
Plane
Hinge
Pivot
Saddle
Cardiac muscle tissue
Network of branching cells with one centrally located nucleus per cell
Pumps blood from heart to lungs and rest of the body
Involuntary
Muscular
Skeletal muscles
Functions: movement, heat production
Cardiovascular
Heart, blood vessels
Functions: transport of nutrients, wastes, oxygen, and carbon dioxide. Electrolyte maintenance
Epithelial
Covers our body and inner surface of body cavities
Functions: provides absorption, protection, secretion, excretion, filtration
Respiratory
Nose, nasal cavity, sinuses, pharynx, larynx, trachea, bronchial tubes, alveoli
Functions: gas exchanges of oxygen and carbon dioxide, maintenance of blood pH and electrolytes; voice production
Male reproductive
Testes, epididymis, vas deferens, prostate, seminal vesicles, bulbourethral glands, urethra, penis, scrotum
Functions: production, maintenance and transport of gametes; production of sex hormones
Connective tissue
Most abundant tower of tissue (bone, blood, cartilage, and Adipose)
Functions: binds structures, provides support and protection, serves as framework, fills spaces stores fat
Urinary
Kidneys, ureters, urinary bladder, urethra
Functions: excretion, maintenance of blood (pH, pressure, etc), maintenance of electrolytes
Smooth muscle tissue
Spindle shaped cells, one central nuclei
Peristalsis, vasoconstriction
Involuntary
Female reproductive
Ovaries, Fallopian tube, cervix, uterus, vagina, labia, clitoris
Functions: houses developing embryo/fetus
Nervous
Cells called neurons; respond to stimuli
Transmit signals from body parts to brain and back
Skeletal muscle tissue
Long thin cells with many nuclei
Moves bones in the body
Voluntary
Endocrine
Endocrine glands that secrete hormones
Functions: maintenance of homeostasis, fight or flight response and electrolyte balance
Tidal volume
Amount of air moved into or out of lungs in a single breath
Inspiratory reserve volume
Deepest breath you can take after a normal breath
Expiratory reserve volume
Maximum amount of air you can breathe out after a normal breath
Residual volume
Gas that remains in lungs to keep it open
Dead space
Portion of respiratory system that has no alveoli therefore no gas exchange happens i.e. the trachea
Minute volume
Respiratory rate x tidal volume
