🗑
What are the accessory organs to the Digestive system   Pancreas and Liver  
🗑
What is a pancreas   Produce insulin and glucagon to regulate blood sugar levels  
🗑
What is a liver   Produce bile, aids in the digestion of fat  
🗑
Where is bile stored   In a pouch under the liver, the gall bladder  
🗑
What is Glucose   a Primary source of energy for the body  
🗑
Constant supply of glucose should be maintained where?   the blood, but must be kept in balance so as not to damage cells.  
🗑
What are Hormones?   produced by pancreas, glucagon and insulin, help cells maintain homeostasis with regard to blood sugar.  
🗑
What is the purpose of the respiratory systems   provider o2 to the blood for cellular respiration in the cells and removes CO2, from the body  
🗑
How does the respiratory system exchange gas?   through the walls of the sacs of the lungs  
🗑
What does the Nasal Cavity (Nose) do?   Warms, filters, moistens air as it passes over mucous membrane.  
🗑
What does the Pharynx (throat) do?   Located where the passages from the nose ad mouth come together.  
🗑
What is Epiglottis?   Flap of elastic tissue that forms a lid over the opening of the trachea.  
🗑
What is the Larynx (Voice Box) is located ?   between the pharynx and the trachea  
🗑
What does the Larynx contain?   Two ligaments - vocal cords that produce sound when air moves through them.  
🗑
What is the Trachea (windpipe)   Tube through which air moves from the pharynx to the lungs  
🗑
What is a Diaphragm   Sheet of muscle below the lungs that separate the chest cavity (thorax) from the abdominal cavity.  
🗑
What does the Diaphram do?   It contracts and relaxes to help inflate and deflate the lungs.  
🗑
What is the internal Respiration ?   The process by which cells get energy from the breakdown of glucose in the presence of oxygen.  
🗑
When does internal respiration occur?   in the Mitochondria  
🗑
What is Bronchi   Two short tubes which direct air into right and left lungs.  
🗑
What is Bronchioles   Millions of smaller tubes that branch off each Bronchi  
🗑
What is Alveoli   Small Sacs found at the end of the bronchioles that are surrounded by capillaries  
🗑
What is Breathing?   the movement of the air into and out of the lungs.  
🗑
What is External Respiration?   The exchange of Oxygen and CO2 between the blood in the capillaries of the alveoli and the air.  
🗑
Where does the External Respiration occur   In the Lungs  
🗑
After food is broken down /digested, what system do the molecules diffuse to?   Circulatory  
🗑
After you take a breath, in to what system does the oxygen diffuse to?   Circulatory  
🗑
Human Circulatory System purpose is   To transport oxygen and nutrients to all the cells in the body and to take carbon dioxide and wastes away from the cells of the body.  
🗑
Human Circulatory System structure consist of ?   Heart and blood vessels  
🗑
What is the Heart?   Main organ that pumps blood  
🗑
What is the Blood vessels?   Tubes through which blood travels  
🗑
What is blood?   .Liquid including read and white blood cells and platelets  
🗑
What is plasma?   thick, yellowish liquid in which blood cells are suspended  
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
