Male: seminal vesicles, prostate gland, penis. Female: ovaries, fallopian, uterus. Produce offspring.
Red bone marrow, thymus, spleen, lymphocyte: protects body with antibodies
Control Center: brain, sensory receptor, spinal cord: responds to internal and external changes.
Kidneys, ureter, urinary bladder, urethra: eliminates nitrogenous wastes, regulates water, keeps acid base balance.
Thoratic duct, lymphatic vessels: Picks up blood leaked from blood, disposes of debris, housed white blood cells
Skeletal muscles: locomotion and facial expressions
eating: oral cavity, esophagus, stomach, intestines, anus: breaks down food for energy and removes waste
transport center: heart, blood: transport blood which carries oxygen, carbon, nutrients and wastes
framework: bones, joints, cartilages: protects and supports body organs
breathing: nasal cavity, pharynx, trachea, bronchus: keeps blood supplied with oxygen and removes carbon dioxide
hormone center: pineal gland, pituitary, thyroid gland, adrenal gland, pancreas, testis, ovaries: regulate growth, reproduction, metabolism.
external body covering: hair, skin, nails: protection, synthesizes, vitamin D, feelings
non-polar covalent bond
formed when electrons are shared equally
atom that gains one or more electrons (negative charge)
atom that loses one or more electrons (positive charge)
neutral subatomic particles
weak bonds that form when a hydrogen atom is attracted by another electronegative atom.
subatomic particle with a positive charge
the capacity to do work; stored or kinetic energy. No mass cannot be measured. put matter into motion.
Polar covalent bond
electron density is unevenly shared between two atoms
anything that occupies space and has mass; substance composing physical objects.
the smallest particle of an elemental substance that exhibits the properties of that element. Protons, neutrons, electrons.
a chemical bond formed by electron transfer between atoms.
a particle consisting of 2 or more atoms joined by chemical bonds.
storage and modification area for proteins, mini-transport
dense bodies that store ribosomes
facilitate protein making
cellular packaging site for exported substances
suicide sacs, digestive enzymes
broad shaped bodies that spin the spindle
power house, ATP
where most organelles are found
external cell boundary, confines contents
control center of the cell, contains DNA
dna bound to protein that appears as strands
largest cells in the body incapable of cell division, make up 90% of tissue mass, rich in vascularity, metabolic activity.
hemocytoblast. fluid within blood vessels. atypical connective tissue. develops from mesenchyme.
Dense Regular CT
packed bundles of collagen fibers running in same direction, forms tendons and ligaments, gives tissue flexibility and resistance to pulling forces. forms aponeuroses.
resistant to wear and tear. covers ends of long bones.
first tissue formed, eventually specializes into all other connective tissues. embryonic CT
Red bone marrow, thymus, spleen: protects the body with antibodies.
mouth containing the teeth and tongue
house the eyes
middle ear cavity
tiny bones of the ear
enclosed within fibrous capsules that surround the freely movable joints of the body.
dorsal body cavity
located nearer to the dorsal or posterior surface of the body
within which the brain is enclosed by the skull
forms a body enclosure around spinal chord
anterior and larger body cavity
group of internal organs housed in ventral cavity
is surrounded by ribs and muscles of chest
housing the lungs
encloses the heart
remaining thoracic organs
toward head or upper body
toward the lower part of body
at the front of body
at back of body
midline of body
away from midline, outer side
a structure between a medial and lateral
closer to the origin of body part
farther from the origin of body part
at body surface
increase in output and decrease in input. variable change in an opposite direction of initial change: thermostat, temp regulation , blood glucose levels, heart rate, blood pressure, oxygen.
result or response of the mechanism. enhances stimulus, activity is accelerated: blood clotting, and labor contractions
runs longitudinally and divides the body or organ into right and left portions (midsagittal- symmetrical and equal)
longitudinally divides body into anterior and posterior (coronal plane)
Horizontally divides body into superior and inferior parts
cuts between a horizontal and longitudinal plane
hormone- secreting glands
