Human body systems
-mouth:chewing breaks down the food into small pieces so i can be easier to digest while mixed with saliva.
-esophagus:is a tube that delivers food to the stomach.
-stomach:holds the food and breaks down acid and powerful enzymes.
-small intestine: made up of 3 parts duodenum,jejunum, and ileum.
-large intestine: (colon) main part of intestine passes through cecum and rectum.
-anus: last part stops poop from coming out and is specialized to detect rectal contents.
-pancreas:large gland behind the stomach
-liver:storage of filtration of blood
-gallbladder: stores bile produced by the liver
-Why digestion of large food molecules is essential? Large food molecules need to be small molecules so the can be absorbed by our body's.
-The need for enzymes in digestion? Most molecules are to big to pass so breaking it down will make it easier.
-Digestive system disorders:-Lactose intolerance cramps bloating, diarrhea-Gallstones,are pieces of solid material that for in gallbladder.
-Excretion:Process of eliminating waste matter.
-Disorders in Excretory System:kidney stones-deposits of calcium,Nephrosis-low blood proteins level,high cholesterol levels,elevated triglyceride levels.
-Circulatory system function: delivers oxygen,nutrients,molecules,and hormones,ammonia,and removal of carbon dioxide and other metabolic waste.
-The relationship between the structure and function:the arteries transport blood away from the heart, the capillaries contain blood at moderate pressure and the veins transport blood towards the heart.
-Disorders: polyarteritis nodosa- its a disease of the small to medium sized arteries,Arteriovenous Malformations-are not normal tangles of blood vessels in a area.
-Alveoli:exchange of oxygen and carbon
-Trachea:carries air into and out of your lungs
-Disorders in the respiratory system are bronchitis,asthma,alveolar
-how carbon dioxide and oxygen are transported in the blood? oxygen is carried to cells and carbon dioxide is moved away from cells.
-active immunity:production of antibodies
-Passive immunity:introduction of antibodies
-Antigen:toxin that induces an immune system response
- Explain why antibiotics are effective against bacteria but not against viruses?bacteria can be killed using antibiotics and viruses can be killed because they don't have metabolic pathways.
-disorders:primary immune deficiency when your born with a weak immune system.
-homeostasis :regulate internal conditions
- negative feedback:reduced output of system
- positive feedback:increases the function in a sysyetm
-Type I Diabetes:pancreas produces little or no insulin
- Type II Diabetes:affects the way the body processes blood sugar.
-spermatogenesis? the formation of sperm
- oogenesis:process of egg formation
-bones:support framework of the body.
-ligaments:tissue that connects one bone to another
- muscles:fibrous tissue that helps producing movement or keeps position of body parts.
- tendons: attaching muscle to bone
