Mini-Practical Terms #3

• lung


  where gas is exchanged in the body. The lungs have alveolis which are small pouches next to the capillaries which maximize surface area for gas exchange
• Lung's System?

  Respiratory System
• Pericardium


  transparent tissue around the heart that acts as mechanical protection for the heart and big vessels. Also acts as a lubrication to reduce friction between the heart and surrounding structures
• Pericardium System?

  Circulatory System
• Heart


  Pumps blood and oxygen around the body as well as delivers waste products back to lungs to be removed
• Heart's System?

  Circulatory System
• Thymus Gland


  Secretes thymosin and trains lymphatic T-Cells that help immune system by protecting body from germs and diseases
• Thymus Gland's System?

  Lymphatic System
• Diaphragm


  muscle that controls the volume of the lungs, affecting the amount of air lungs receive
• Diaphragm's System?

  Respiratory System
• Thymus Tissue


  The tissue on top of the heart, the site of maturation for T-cells aids, aids in the production of lymphocytes
• Thymus Tissue's System?

  Lymphatic System
• Thyroid Gland


  Makes and releases hormones to maintain metabolism such as thyroxine and triiodothyronine
• Thyroid Gland's System?

  Endocrine System
• Trachea 


  a tube that runs from the larynx to top of the lungs, trapping small debris from entering your lungs using mucus. It also contains cilia which push particles out of trachea to exit the respiratory tract
• Trachea's System?

  Respiratory System
• Larynx


  Does various things such as protects lower respiratory tract from food, as well as is a sound box (air vibrates vocal chords)
• Larynx's System

  Respiratory System
• Spleen 


  manages level of red and white blood cells and platelets, filtering old or damaged ones. Also has an immune function
• Spleen's System?

  Lymphatic and Circulatory System
• Cecum


  Section in large intestine that only herbivores possess. Digests cellulose with an enzyme they produce (cellulase). Cellulose goes to feces
• Cecum's system?

  Digestive System
• Small Intestine 


  where most chemical digestion occurs. Nutrients are absorbed by diffusion, using villus to increase the speed. ALso undergoes perastalsis. Bile.
• Small Intestine's System?

  Digestive System
• Stomach


  breaks down food into chyme. The mechanical function of the stomach is peristalsis, which is the reason why our stomach growls. The chemical digestion is HCI creating an acidic environment with a ph of 2, activating the enzyme pepsinogen into pepsin, which is then able to digest proteins. The stomach has a mucus lining protecting it
• Stomach's System?

  Digestive System
• Greater Omentum


  tissue connecting the stomach to the spleen
• Greater Omentum's System?

  Digestive System
• Large Intestine


  dehydrates remaining water and electrolytes/nutrients, moving food throughout the body through peristalsis. Bacteria grows undigested material that turns to vitamins B & K. Has 3 parts connected to it: the colon, rectum, and anus. The colon carries waste to be expelled by the anus, also absorbing food to form stool. The rectum is where feces is held before it's expelled through the anus. The anus is the external opening of the rectum.
• Large Intestine's System?

  Digestive System
• Pancreas


  has many digestive enzymes that do various tasks such as pancreatic juice and hormones that break down sugars, fats, and starches, glucagon and insulin which regular blood sugar levels, sodium bicarbonate, which neutralizes stomach acid entering small intestine, pancreatic amylase which breaks down starches into sugars, pancreatic lipase which helps digest fats in the small intestine, and glycogen
• Pancreas's System?

  Digestive and Endocrine System
• Gallbladder 


  Stores excess bile before releasing into small intestine in small amounts
• Gallbladder's System?

  Digestive system
• Umbilical vein 


  carries newly oxygenated blood from placenta to fetus
• Umbilical chord


  connects mother and fetus pig
• Umbilical Vein and chord's System?

  circulatory/fetal system
• Liver


  creates bile, detoxifies, and metabolizes
• Liver's System?

  Endocrine and Digestive System
• Left and Right Auricle


  muscular pouches that extend from the atrium, increases holding capacity of the atria
