CHAPTER 7 - BODY SYSTEMS Flashcards
Skeletal
our bones
How many bones does that appendicular skeleton have?
126
Osteoporosis
Age related disease where the bone demineralize
What are the three layers of bones?
1.Periosteum
2.Compact bone
3.Cancellous bone
What is the compact bone?
Forms outer layer of bone
hard dense and very strong
Cancellous bone
Found inside of the bone
(light in weight)
contains the bone marrow-> makes blood cells
What are joints called
articulations
What are the three types of joints?
- Fibrous joint
2.Cartillaginous Joint
3.Synovial joint
The fibrous joint moves. true or false
false. Does not move
what is the cartilaginous joint made of? and does it move?
connective tissue and cartilage.
it moves very slightly
What is the synovial joint?
Most moveable joint and accounts for most joints in the body.
filled with fluids called the synovial fluid thats acts as a cushion to ease movement
Name the three types of muscle
1.striated
2.smooth muscle
3. cardiac muscle
What is muscle origin?
place where the muscle begins
What is muscle insertion?
Place where the muscle ends (inserts)
What is the circulatory system?
delivers oxygen and nutrients to cells and takes away wastes.
-Gets rid of carbon monoxide and waste products from the body cells.
-Regulates body temperature
Endocarditis
Inflammation of endocardial layer of the heart; can be caused by bacteria
What are the three types of blood vessels
- Arteries
2.Veins
3.Capillaries
The function of arteries
carry blood from the heart to the body
Function of veins
Carry blood from the body towards the heart
Function of capillaries
Connect the arteries and veins together
Lymph Nodes
Small or round oval structures that are located in lymph vessels. fight disease by producing ANTIBODIES.
Tonsils
Masses of lymphatic tissue on both sides of the throat, behind the tongue. Forms a protective ring to help fight infections
Spleen
LARGEST of the lymphoid organs. fights bacteria and viruses
Lymphadenopathy
enlargement or swelling of one or more lymph nodes.
What is the nervous system
The communication channel of the body.
starts from the brain and channels out to the body.
neurons
direct communication from the brain
or nerve impulses
what is the Brain
Primary center for regulating and coordinating body activities.
Epilepsy
a condition that causes seizures
Bells palsy
paralysis of one side of the facial nerve that causes distortion and unsymmetrical features on the face
Periosteum
Cover of the bone
-necessary for bone growth, repair & nutrition & carrying away waste
-contains OSTEOBLAST (cells associated with making new bones)
Respiratory System
Delivers oxygen to the cells in the body
the network of organs and tissues that help you breathe
-Transports carbon dioxide OUT of the body
Tuberculosis
Infectious disease caused by infected droplets called tubercle
-highly contagious and is spread through saliva.
Epiglottis
moveable lid above the larynx that prevents food and drink from entering your windpipe
Endocrine System
The endocrine system is made up of glands that make hormones. Hormones are the body’s chemical messengers which carry information and instructions from one set of cells to another.
Where are hormones produced?
ENDOCRINE GLANDS
Urinary System
filters blood and create urine as a waste by-product.
Renal Failure
Loss of kidney function (also known as kidney failure)
Integumentary System
SKIN - first line of defense against disease
Function of the Integumentary system
- regulates body temp
-barrier that prevents bacteria from entering body
-excretes liquids and salt
-provides sensitivity to touch
-uses ultraviolet rays from the sun to convert chemicals into VITAMIN D.
Abscess
Collection of bacteria that enters the skin
