Healthcare #1 test Flashcards
Atoms
The microscopic building blocks of matter
Molecules
Atoms combine with one another to form molecules.
Macromolecules
Molecules combine to form macromolecules
Cells
The association of molecules with one another creates the cell. The cell is the fundamental unit of living things. Among the different cells in the body are nerve cells, muscle cells and blood cells.
Tissue
A group of cells of similar structure performing the same function. The body has four basic types of tissues: epithelial tissue (such as in the organ linings), connective tissue (such as blood and bone), muscle tissue and nervous tissue.
Organ
An organ is composed of two or more different kinds of tissues. The stomach is an organ composed of epithelial tissue, muscle tissue, nerve tissue and connective tissue. An organ functions as a specialized physiological center for a particular activity.
Organ system
A collection of several organs with related functions.
Organism
All of the systems operating together forms the organism, which is the highest level of organization.
Muscle Tissue
Contains cells that have the ability to contract in order to produce movement of different body parts.
Nervous Tissue
Found in the brain, spinal cord & nerves. Is the body’s communication network by
conducting electrical signals across tissue.
Epithelial Tissue
Forms covering over all the body surfaces, lines body cavities and hollow organs. They have many functions including secretion, protection, absorption, excretion, filtration, diffusion, and sensory reception.
Connective Tissue
a name given to several different body tissues which help connect, support and bind other tissues in the body. Examples include: bone, cartilage, fat, blood, lymphatic tissue, etc.
Integumentary system
- Covers body and protects it
- Skin, hair, nails, glands
Skeletal system
- Protects body, provides support for movement
- Bones, cartilage, and ligaments
Nervous system
- Receives stimuli, sends information, directs body
- Brain, spinal cord, nerves, sense organs
Endocrine system
- Coordinates, integrates the activities of body
- Pituitary, adrenal, thyroid, ductless glands
Muscular system
- Produces body movement
- Skeletal, smooth, cardiac
Digestive system
- Absorbs soluble nutrients from ingested food
- Teeth, esophagus, liver, stomach, intestines, etc.
Respiratory system
- Collects O2 and exchanges it for CO2
- Lungs, pharynx, trachea and other air passages
Circulatory system
- Transports cells & material throughout body
- Heart, blood vessels, blood, lymph structures
Immune system
- Removes foreign chemicals and microorganisms from the bloodstream
- T and B- lymphocytes, and macrophages; lymph structures
Urinary system
- Removes metabolic wastes from the bloodstream
- Kidney, bladder, and associated ducts
Reproductive system
- Produces sex cells for the next generation of organism
- Testes, ovaries etc.
Homeostatis
The tendency of an organism to maintain a steady state condition
conditions that need to be maintained
- Blood pressure
- Acid/Base levels
- Fluid balance
- Blood sugar levels
- Blood oxygen levels
- Body temperature
Imbalances in Blood Sugar
Can lead to hypo- or hyper-glycemia. There will be both signs and symptoms of hypo or hyperglycemia which can be used to diagnose a patient.
SEEDS
S-Sleep: Getting 7-9 hours of sleep per night.
E- Exercise: Exercising 3-5 times a week.
E- Environment: Having a clean, positive, healthy environment.
D-Diet: Following the Food Guide and balance of macro/micronutrients.
S- Stress: Managing stress levels in a healthy way
