exam 3,4,5 Flashcards
function of selectively permeable membrane
protects the cell
pinocytosis
movement of fluid and dissolved molecules into a cell by trapping them in a section of plasma membrane
control center of the cell
the nucleus
protein factor of the cell
ribosomes
skin, hair, nails, exocrine gland are organs in this system
Integumentary system
bones, cartilage, ligaments and tendons are organs in this system
Skeletal system
brain, spinal cord, and nerves are organs in this system
Nervous system
heart, arteries, veins and capillaries are organs in this system
Cardiovascular (circulatory) system
Lymphoid tissue, lymph nodes, tonsils, thymus glands are organs in this system
Lymphatic system
protective cells, antibodies, bone marrow, spleen, mucous membranes and skin are organs in this system
Immune system
nose, pharynx, larynx, trachea, lungs, alveoli, diaphragm are organs in this system
Respiratory system
Mouth, pharynx, esophagus, stomach, small intestine, colon, rectum and anal canal are organs in this system
Digestive system
Kidneys, ureters, bladder and urethra are organs in this system
Urinary system
testes, ovaries, penis, scrotum, uterus, fallopian tubes, vagina, vulva, mammory glands are organs in this sytem
Reproductive System
3 main parts to a cell
plasma membrane, cytoplasm and nucleus
Active transport processes
Ion pump, phagocytosis, pinocytosis; uphill movement and requires energy
passive transport processes
diffusion, osmosis, dialysis, filtration; downhill movement that does not require energy
what makes up a structure of a cell membrane
2 phospholipids
type of tissue that allows rapid communication between various parts of the body
Nervous Tissue
hyperplasia
increase in cell reproduction
anaplasia
production of abnormal, undifferentiated cells
benign
growths that are not cancerous or dangerous; usually encapsulated
malignant
growth that is cancerous and has poorly defined edges
fabric of the body
tissues
4 types of tissues
epithelial, connective, muscle, and nervous
epithelial tissue is found
on outer layer of skin
connective tissues is found
in skin, membranes, muscles, bones, nerves, all internal organs
nervous tissue is found
in brain, spinal cords, and nerves
muscle tissue is found
in liver, pancreas, and intestines
carries nerve impulse to neuron cells body
Dendrite
carries impulses away from cells body
Axon
function of connective tissue
provides structural and functional support
primary organs of digestive system
mouth, pharynx, esophagus, stomach, small intestine, colon, rectum, anal canal
secondary organs of digestive system
Teeth, salivary glands, tongue, liver, gallbladder, pancreas, appendix
types of tissue that are connective
Fibrous, Bone, cartilage, blood, hematopoietic tissue
where respiratory system exchanges carbon dioxide for oxygen
alveoli
what makes up central nervous system
brain and spinal cord
what makes up peripheral nervous system
cranial nerves, spinal nerves
cilia located in
respiratory tract
microvilli located in
plasma membrane
plays a role in protein synthesis
DNA and RNA
