Question | Answer |
---|---|
prokaryote | cells or organisms without a nucleus |
eukaryote | cells or organisms with a nucleus |
human body (somatic) cells | 23 paired chromosomes (46 total including X/Y) - diploid |
human sex cells | 23 unpaired chromosomes - haploid |
mitosis | somatic cell division |
meiosis | sex cell division into sperm or egg |
four tissue types | epithelial, connective, muscle, nervous |
first three embryonic "layers" | ectoderm, endoderm, mesoderm |
ectoderm | forms functional epithelium including integument and dorsal cavity plus CNS and special sensory organs |
endoderm | forms functional epithelium including integument and ventral cavity plus vessels and most other organs |
mesoderm | forms connective, muscle and nerve tissue plus spleen, kidney, muscles and peripheral nervous system organs |
embryonic epithelial tissue | ectoderm and endoderm |
embryonic connective, muscle and nerve tissue | mesoderm |
parenchyma | functional bulk of an organ; mostly epithelial in origin |
organ | instrument or tool whereby two or more tissues acting in concert towards a common function |
contains "main" and "sporadic" tissues | organ |
organ system | group of organs acting in concert towards a common function |
organ system that includes skin (epidermis, dermis, hair and nails) | integumentary system - separates body from environment |
organ system that includes salivary glands, oropharynx, epiglottis, esophagus, stomach, liver, pancreas, duodenum, jejunum, ileum, color, rectum | digestive system - takes in energy and nutrients |
organ system that includes nasopharynx, epiglottis, larynx, trachea, bronchi, bronchioles, alveolae | respiratory system - exchanges carbon dioxide for oxygen |
organ system that includes heart, great vessels, arteries/veins/lymphatic vessels, arterioles/venules/small lymphatic vessels, capillaries, blood, inflammatory/immune cells | cardiovascular system - distributes substances throughout the body |
organ system that includes central and peripheral nervous systems along with special sensory organs and spinal/autonomic nervous systems | nervous system - fast control |
organ system that includes regulatory endocrine glands such as hypothalamus, pituitary, pineal, thyroid, parathyroid, adrenal and sex glands | endocrine system - slow, sustained control |
organ system that includes bones, cartilage, ligaments, tendons | skeletal system - supports body against gravity |
organ system that includes skeletal and smooth but not necessarily cardiac muscles | muscular system - provides movement |
organ system that includes kidneys, ureters, bladder, urethra | excretory system - maintains fluid and electrolye balance |
organ system that includes breasts, ovaries/testes, Fallopian tubes/vas deferens, uterus/prostate, vagina/penis | reproductive system - reproduces species |
3:4:10 | embroyonic layers, tissues, organ systems |
primary healing or healing by first intent | damaged cells repair themselves, and remain functional |
secondary healing or healing by second intent | resting, committed stem cells produce new functional cells |
fibrosis or scarring | connective tissue cells replace parenchyma with non-functioning cells |
histamine | chemical released by most of the body's damaged cells |
ligaments | organ whose primary tissue is connective and that binds bones to bones |
tendons | organ whose primary tissue tissue is connective and that binds muscles to bones |
axial bones | bones like vertebrae located along the central axis |
the femur or thigh bone is a _____ bone (shape) | long |
epiphyses | ends of a long bone |
diaphysis | shaft of a long bone |
