Chapter 6 Flashcards
the most magnificent part of God’s creation
man
contains the brain
cranial cavity
contains spinal cord
spinal cavity
contains heart, lungs, esophagus, windpipe, thymus and aorta
thoracic cavity
contains the liver, stomach, pancreas, spleen kidneys, urinary bladder, small intestine , large intestine, reproductive organs
abdominal cavity
all the soft, internal organs within the thoracic and abdominal cavities are called
vicscera
how many functioning body systems are there?
11
a group of structures that function together as a unit to perform a definite job for the body
system
systems used to pickup and deliver oxygen, food, and water to the cells and carry away waste; include the heart, arteries, veins, capillaries,
circulatory system
carry blood away
arteries
carry blood to the heart
veins
the system that defends the body from disease and foreign invaders
immune system
the most important part of the immune system
white blood cells
the important system within the immune system that is a network of vessels that collect lymphatic fluid from teh body’s tissues
lymphatic system
serve as bases from which white blood cells stage attacks against invaders
lymph nodes
system whose main function is to supply blood tissues with oxygen and to remove carbon dioxide
respiratory system
system that make a path through the thoracic and abdominal cavities and is composed of a number of organs that make up the alimentary tube that leads from the mouth to the anus
digestive system
the tube that transports food from the mouth to the stomach
esophagus
where digestion is completed and nutrients are absorbed into the bloodstream
small intestine
organ that absorbs water from undigested food before it is expelled from the body
large intestine
system that provides a number of openings through which a variety of waste materials are removed from the body
excretory system
these excrete urea and salts from the body
sweat glands
filter the blood, removing excess water, urea, uric acid, and other waste materials
kidney
stores liquid wastes from kidneys until they are excreted
urinary bladder
tube connecting the bladder to the outside of the body
urethra
system that coordinates the activities of the body
nervous system
the most important organ of the nervous system and is considered the master control unit of the body
brain
system that produces hormones to control certain activities
endocrine system
system that protects the body from its surroundings and bacteria and other microbes
integumentary system
system made up of 206 bones and numerous ligaments
skeletal system
system that provides movement to the body
muscular system
muscles that consciously controlled
voluntary muscles
muscles that operate withou conscious thought
involuntary muscles
system responsible for the continuation of the human race
reproductive system
a new living being begins at
conception
the time when the male gamete unites with the female gamete
fertilization
muscular organ the mother’s abdomen fro the development of the child
uterus or womb
a stble internal environment in the body
homeostasis
help maintain homeostasis by detecting change in the body and directing the body to respond appropriately
feedback mechanisms
make up most feedback mechanisms and reverse the effect of a change
negative feedback mechanisms
maintain or intensify the effect of a change
positive feedback mechanisms
organs are composed of various types of
tissues
a group of cells that work together to accomplish the task of an organ
tissue
four broad categories of tissues
epithelial, connective, muscle, and nerve
tissues that move the body and its parts
muscle tissue
tissue that conrols organs and coordinates all their functions
nerve tissue
tissues that line all body parts
epithelial tissues
tissues that connect the parts of the body
connective tissue
types of connective tissue
bones
tendons
ligaments
cartilage
fat
blood
lymph
liquid connective tissues
blood
lymph
the area surrounding and between tissues contains
interstitial fluid
thin, flexible sheets of tissues that cover or line a part of the body
membranes
four basic types of membranes
serous
mucous
cutaneous
synovial
membrane that consists mostly of epithelial tissues line enclosed body cavities
serous membrane
membranes made of epithelial tissues that line openings to the outside
mucous membranes
membranes of the skin which are composed of several types of tissues
cutaneous membranes
membranes the line the joint cavities
synovial membranes
the material surroundings cells
matrix
the matrix of blood tissue is
plasma
organs that were believed to have no useful purpose today
vestigial organs
