Tissue
What is tissue?
A group of cells that have a similar structure and function together as a unit.
what are the 9 major organ systems?
* integumentary system
* musculoskeletal system
* respiratory system
* the digestive system
* the circulatory system
* the excretory system
* the nervous system
* the endocrine system
* the reproductive system
what are the 3 main planes?
* the sagittal plane
* the coronal plane
* the transverse plane
what is a macromolecule?
a molecule containing a very large number of atoms
what is the organelles main function?
* to maintain homeostasis in the cell
What is the human body's largest tissue?
Skeletal muscle tissue
What is the most important organ system?
the nervous system
what are the 5 anatomical parts?
head, neck,thorax, abdomen, pelvis,
what do macromolecules carry?
* proteins
* nucleic acid
* DNA
* RNA
* Lipids
* Polysaccharides
what organelles work together best?
* the nucleus, mitochondria, lysosomes, the endoplasmic reticulum and the golgi apparatus
what epithelial cells make up the lining of the kidney tubules, ducts of glands, and surface of ovaries?
simple cuboidal cells
What bones protect your spinal cord?
the vertebrae
what is plane?
a hypothetical plane used in describing the location of bodily structures or movement directions.
what is the macromolecules main function?
* provide structural support, a source of stored fuel,the ability to store and retrieve genetic information and the ability to speed biochemical reactions
what is an organelle?
* any of a number of organized or specialized structures within living cells.
What is epithelial tissue and its function?
epithelial tissue spans throughout the body, covering the bodies surfaces, lines body cavities, and hollow organs, they are the major tissue glands.
epithelial tissue function: protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
How does the muscular system help the digestive system?
smooth muscle allows organs to contract to push food through the esophagus, stomach and intestine
what is sagittal plane movement?
a vertical line that divides the body into left and right sides, flexion and extension types of movement occurs in this plane.
what are the 4 main macromolecules?
* proteins
* carbohydrates
* nucleic acids
* lipids
what are the 12 organelles of a cell?
* nucleus, ribosome, vesicle, rough endoplasmic reticulum, golgi apparatus, cytoskeleton, smooth endoplasmic reticulum, mitochondria, vacuole, cytosol, and lysosome/
what are the 4 epithelial tissues, and what are their functions?
1.) simple squamous, simple cuboidal, simple columnar, pseudostratified
2.)simple squamous: allows selective diffusion of materials to pass through
* simple cuboidal: secretory, absorptive, and sometimes provides protection
*simple columnar: protection
*psuedostratisfied: absorption and secretion of mucus and protection of foreign particles.
how does the circulatory system work with the digestive system?
the blood carries nutrients absorbed from digested foods
what are 10 of the anatomical directions?
*anterior
*posterior
*distal
*proximal
*dorsal
*ventral
*superior
*inferior
*lateral
*medial
what are the 4 main monomers?
* amino acids
* fatty acids and glycerol
* monosaccharides
*nucleotides
what is the difference between cells and organelles?
*cells are membrane bound groups of organelles that work together to let it function
