Unit 1 & 2 Flashcards
Consists of bones, cartilage, ligaments, and tendons. It accounts for 20% of body weight
Skeletal System
What are the four types of bones?
Long bones, Short bones, Flat bones, Irregular bones
Where two bones join together
Joint
The top flexible tissue that covers the ends of the bones of freely movable joints and protects the bones by preventing them from rubbing against each other. A tough, but flexible tissue that covers the bones
Cartilage
A connective tissue that binds one bone to another.
Ligament
A connective tissue that attaches/binds the muscle to bone
Tendon
The body system responsible for movement
Muscular System
Moves our bones and controls facial expressions and eye movements
Striated Muscle
These muscles line the walls of internal organs
Smooth Muscle
This muscles is only found in the heart and is a combination of both striated and smooth muscle
Cardiac Muscle
The control center for all actions that occur consciously and unconsciously and the communication among body parts
Nervous System
The nervous system is divided into two parts:
Central Nervous System (CNS) and Peripheral Nervous System (PNS)
Messages travel through the spinal cord to the brain then directs all functins for the body
Central Nervous System
Consists of all the nerves outside the brain and spinal cord; These nerves relay messages between the CNS And other areas of body
Peripheral Nervous System (PNS)
Works with the cardiovascular system to provide oxygen to the cells and remove carbon dioxide
Respiratory System
What are the four parts of the respiratory system?
lungs, passageways for airflow, blood vessels, and muscles.
These are divided into the upper respiratory tract in the lower respiratory track
Respiratory passages
Consists of the heart and blood vessels; Primary function is to transport a constant supply of nutrients and oxygen to the body cells through the flow of blood
Cardiovascular System
What is responsible for circulating blood throughout the body
Heart
Carries oxygen poor blood back to the heart
Veins
Carries blood away from the heart to the body tissue
Arteries
The constant supply of nutrients and oxygen to the body cell through the flow of blood
Circulation
Includes digestive tract and it’s accessory organs; The role is to process food into molecules that can be absorbed and utilized by the cells of the body
Digestive System
What are the four functions of the digestive system
ingestion, digestion, absorption, and elimination
What system balances the fluids in your body by producing, storing, and eliminating urine
Urinary System
What are the organs in the Urinary System?
Kidneys, Ureter, Urethra, and the Bladder
What do Kidneys do?
The kidneys filter out waste products, reabsorb water and other substances, and produce urine
A complex network of cells, tissues, and organs that work together to defend and protect the body against foreign invaders second cause sickness and disease. This system also produces, stores, and carries white blood cells around the body
Immune System
What are Leukocytes?
White Blood Cells
An informational signaling system that sends chemical messages called Hormones; Hormones influence growth, development, and energy producing activities
Endocrine System
What is the purpose of the Endocrine System?
To keep the body in a state of homeostasis or balance
This system is made up of Hair, nails, skin, and associated glands; Skin, hair, nails, and fluid secreted by glands cover and protect various parts of the body
Integumentary System
These systems produce, nourish, and transport either the egg or the sperm
Reproductive Systems
A cycle of changes in the female hormone production that lasts about 28 days.
Menstrual Cycle
If the egg is unfertilized hormone changes will cause the uterus to shed
Menstration
This is when the egg is released from the ovary
Ovulation
When the sperm cells travel into the Fallopian Tube and penetrates the ovum
Fertilization
Women are born with all of the eggs that she will ever use. When the eggs run out and estrogen levels drop menopause begins
Menopause
What are the four main types of germs?
Bacteria, Viruses, Fungi, and Parasites
One-called germs that multiply quickly
Bacteria
Tiny capsules that contain genetic material
Viruses
Primitive plant like organisms such as mushrooms, mold, mildew, and yeast
Fungai
Animals or plants that survive by living on or in other living things
Parasite
How can germs be transmitted
Direct Contact, Indirect Contact, bites, and contamination
This includes kissing, touching, sneezing, coughing, and engaging in sexual contact. Pregnant moms can also pass germs along to their babies
Direct Contact
This involves touching something that has germs on it
Indirect contact
You can get infected through bites of either insects or animals
Bites
Food, water, soil, or plants can become contaminated with germs
Contaminate
Diseases that are caused by bacteria, viruses, fungi, and parasites
Infectious (communicable) Diseases
Infections of the nose and throat and are caused by more than 200 different viruses and are spread by infected droplets of fluid that can be inhaled or transferred via touch. Symptoms include Watery eyes, Nasal And chest congestion, sneezing, sore or scratchy throat.
Common Cold
Caused by the influenza virus that infect the nose, throat, and lungs; It is spread by infected droplets of fluid that are inhaled or transferred via touch; Symptoms include Fatigue, muscle stiffness, coughs, sore throat, nasal congestion, headaches, and high fever
Influenza (flu)
A virus that is transmitted through saliva, and air droplets through a cough or sneeze, or through sharing a drink or food utensils with someone who has mono. Symptoms include Fatigue, swollen lymph nodes in your neck and armpits, swollen tonsils, sore throat, swollen spleen, fever, headache and skin rash.
Mononucleosis (mono)
How do you prevent respiratory infection?
- Wash your hands frequently in hot water
- Avoid contact with someone who is sick
- Avoid sharing beverages, utensils, and lip products
- Best way to prevent the flu is getting the flu vaccine every year
The thin tissue that surrounds the brain and spinal cord
Meninges
An inflammation of the tissue that surrounds the brain and spinal cord. It is caused by either a virus or bacteria. Symptoms include sudden high fever, stiff neck, and nausea. It can cause stroke, hearing loss, or brain damage
Meningitis
Both pneumococcal infections and meningococcal infections are caused by…
bacterial meningitis
This type of meningitis can cause stroke, hearing loss, and brain damage. Transmitted when a virus enters the body through the nose/mouth then travels to the brain
Viral meningitis
This form of meningitis is rare but deadly b/c it can effect other organs
Bacterial meningitis
How to prevent Meningitis
- Wash your hands/ practice good hygiene
2. Vaccines can prevent bacterial meningitis
