The synthesis of complex molecules
27
Catabolism
The breakdown of complex molecules
28
Absorption
The process of bringing material into the body
29
Respiration
The absorption, transport, and use oxygen by cells
30
Excretion
The removal of waste
31
Integumentary system
Protects against environmental hazards; helps control body temperature. Organs: skin, hair follicles, sweat glands, nails, sensory receptors, subcutaneous layer
32
Skeletal system
Supports and protects tissues; stores minerals forms blood cells. Organs: bones, cartilages and joints, axial skeleton (skull, vertebrae, sacrum, coccyx, sternum, supporting cartilages, and ligaments, appendicular skeleton (limbs and supporting bones and ligaments), ligaments, bone marrow
33
Muscular System
Allows for locomotion provides support; produces heat. Organs: skeletal muscles, axial muscle, appendicular muscles, tendons and aponeuroses
34
Nervous system
Directs immediate responses to stimuli, usually by coordinating the activities of other organ systems. Organs: central nervous system (CNS), brain, spinal cord, special senses, peripheral nervous system (PNS)
35
Endocrine system
Directs long-term changes in activities of other organ systems. Organs: Pineal gland, pituitary gland, thyroid gland, parathyroid gland, thymus, adrenal glands, kidneys, pancreas, gonads: testes, ovaries
36
Cardiovascular system
Transports cells and dissolved materials, including nutrients, wastes, and gases
37
Lymphatic system
Defends against infection and disease; returns tissue fluid to the bloodstream. Organs: lymphatic vessels, lymph nodes, spleen, thymus
38
Respiratory system
Delivers air to sites where gas exchange can occur between the air and circulating blood produces sound. Organs: nasal cavities and paranasal sinuses, pharynx, larynx, trachea, bronchi, lungs-alveoli
39
Digestive system
Processes food and absorbs nutrients. Organs: oral cavity, salivary glands, pharynx, esophagus, stomach, small intestine, liver, gallbladder, pancreas, large intestine
40
Urinary system
Eliminates excess water, salts, and wastes. Organs: kidneys, ureters, urinary bladder, urethra
41
Male reproductive system
Produces sex cells and hormones. Organs: testes, accessory organs-epididymis, ductus deferens, seminal glands, prostate, urethra, external genitalia-penis, scrotum
42
Female reproductive system
Produces sex cells and hormones; supports embryonic and fetal development from fertilization to birth. Organs: ovaries, uterine tubes, uterus, vagina, external genitalia-clitoris, labia, mammary glands
43
Superficial anatomy
Used to understand structures that are deep to (internal to) the integument, anatomical landmarks, regions, directions
44
Sectional anatomy
Electric imaging allows us to see inside the body. The sectional view is kept to illustrate the anatomy of 3D objects, planes and sections, body cavities
45
Anatomical position
Standing with the feet flat on the floor, hands by side, palms facing forward, supine:lying down (face up), prone: lying down (face down)
46
Anatomical regions
Areas of the human body defined by the landmarks provided by evident structures that are easily palpable or visible; cephalon (head), trunk, upper limb, lower limb
47
Abdominopelvic quadrants
Abdomen and pelvic regions can be subdivided into four sections
48
Abdominopelvic regions
The abdomen and pelvic regions can be subdivided into nine sections
