What is the purpose of the cardiovascular system? |
-Carries out materials like oxygen and nutrients to cells -Gets rid of carbon dioxide from cellular respiration -fights diseases with white blood cells |
|
What does The heart do? |
Cardiac muscles that pumps blood throughout the body |
|
Atria |
Receives blood |
|
Ventricles |
Pumps blood to the rest of the body |
|
Valves |
Prevents blood from flowing backwards |
|
What is in blood? |
Plasma, RBC, WBC, platelets |
|
What are the different kinds of blood types? |
A, b, ab, o |
|
Arteries |
Carry blood away from the heart |
|
Veins |
Carry blood towards heart |
|
Capillaries |
Exchange materials (nutrients, oxygen, carbon dioxide) between blood and body cells |
|
Respiratory system |
Brings in oxygen which is needed for cellular respiration and gets rid of carbon dioxide made by cellular respiration |
|
Urine |
Excess water, salts, and urea (toxic substance that comes from the break down of protein) |
|
Kidney |
Separates needed materials from not needed materials |
|
Pharynx |
Throat |
|
Carynx |
Voice box |
|
Wind pipe (frachea) |
Connects to bronchi |
|
Trachea |
Filter oxygen again before it reaches the lungs. Celia and mucus help to clean oxygen |
|
Bronchi |
Takes that lead to lungs |
|
Lungs |
Made up of tiny air sacs called alveoli. Capillaries surround each alveoli and exchange oxygen and carbon dioxide |
|
Skeletal system functions |
-Provide shape and support -helps you move -protects organs -produces red blood cells -stores minerals: calcium |
|
Parts of skeletal system |
Bones, cartilage, vertebrae, joints, tendon, ligament |
|
Muscular system |
Keeps the heart beating and moves the body |
|
Skeletal muscle |
Voluntary muscle that provides the force that moves your body |
|
Tendons |
Attach muscles to bones |
|
Ligaments |
Attach bones to bones |
|
Smooth muscles |
Involuntary muscle that control movement inside the body |
|
Cardiac muscle |
Involuntary muscle that controls the heart beat |
|
Digestive system |
Breaks down food into nutrients that diffuse across cell membranes. Eliminates undigested food from body |
|
When does digestion begin? |
When you see/smell food |
|
Mechanical digestion |
Physically breaking down food Ex- chewing |
|
Chemical digestion |
Using chemicals to break down food |
|
Small intestines |
Most chemical digestion occurs here. |
|
Helper organs and their purposes |
Liver- produces bile (enzyme that digests fat). Bile gets stored in the gall bladder and is secreted into the small intestine |
|
Pancreas |
Produces many enzymes that secrete into intestines |
|
Large intestine |
Water gets reabsorbed and undigested material is eliminated |
