Chapter 1 And 4 Flashcards
Histology
Study of microscopic structures of tissues
All of the tissues in the human body are grouped into four general tissue types:
•Epithelial tissue
•Muscle tissue
•connective tissue
• Nervous tissue
Epithelial tissue
•line body cavities and hollow organs and it covers body surfaces that are exposed to the environment.
•cells are tightly packed together with little space in between them.
•located on free surfaces, they must attach to underlying tissue which occurs on the basement membrane
Basement membrane is
A thin extracellular structure that consists of two layers : basal lamina and reticular lamina
Integumentary system
Consists of-
What it does-
Consists of -hair, skin and nails
•protects body from external environment
•produces vitamin D
•retains water
•regulates body temperature
Skeletal system
•Consists of-
•what it does
Consists of- bones and joints
•supports the body
•protects internal organs
•provides leverage for movement
•produces blood cells
•stores calcium salts
Muscular System
-consists of
-what it does
-consists of- skeletal muscle’s
•produces movement
•controls body openings
•generates heat
NERVOUS SYSTEM
-consists of
-what it does
-Consists of- brain, spinal cord and nerves
•regulates body function
• provides for sensation, movement, automatic functions, and higher mental functions via nerve impulses
ENDOCRINE SYSTEM
-consists of
-what it does
-consists of: pineal gland, hypothalamus, pituitary gland, thyroid gland, thymus gland, adrenal gland, pancreas, ovaries-female and testes-male
• Regulates body functions
• Regulates the functions of muscles, glands, and other tissues through the secretion of chemicals called hormones
CARDIOVASCULAR SYSTEM
-consists of
-what it does
-Consists of - heart and blood vessels
• Pumps and delivers oxygen-poor blood to the lungs and oxygen-rich blood to the tissues
• Removes wastes from the tissues
• Transports cells, nutrients, and other substances
