Extra Flashcards
What affects solubility?
- Type of solute.
- Type of solvent.
- Temperature
What is Archimedes Principles?
Archimedes’ principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.
What are the parts of the digestive system?
- Salivary glands - chemically break down food
- mouth - Chew and stuff
- esophagus - tube where food goes down to the stomach. Peristalsis happens here. That is contractions of muscle to push food down.
- stomach - muscular wall churns food to break it down. Food gets mixed with gastric juice.
- small intestine - From the stomach, the food that is now liquid gets released into the small intestine where chemical digestion continues.
- pancreas - the pancreas sends enzymes to the small intestine.
- liver - produced a substance called bile. Which is stored in the
- gall bladder - in the gall bladder. The gall bladder sends the bile to the small intestine where is breaks large globules of lipids into much smaller droplets.
- small intestine - (again) next the small intestine absorbs these particles. The inner surface turns into villi are covered with epithelial tissue and food particles get absorbs by this. The food particles get transferred into the bloodstream. Microvilli helps further breaks down the food.
- large intestine - finally the digestion has finished. The part of the food that has not been digested and turned into the feces. Then it is sent to the rectum.
What is the function of the whole digestive system?
Break down food pieces into much smaller pieces (particles) so they can be absorbed and transported throughout the body.
What are the parts and function of the parts of the Respiratory system?
- nose - inhale oxygen and exhale carbon dioxide.
- mouth - inhale oxygen and exhale carbon dioxide.
- trachea
- bronchi - brings air into the lungs through passageways.
- bronchioles - narrow into smaller passageways to bring into the lungs.
- lungs - in and out ways of air
- diaphragm - when u inhale it brings your diaphragm down and ribs up. When u exhale it pulls your diaphragm up and ribs down.
What is the function of the respiratory system?
- transport oxygen from the outside air to blood.
- transport carbon dioxide from the blood to the outside air.
What is the parts of the circulatory system and functions of the parts?
- Heart - the heart is the pump (two pumps). The right side pumps blood to your lungs. The left side receives blood from your lungs and pumps it everywhere else in your body.
- Arteries - the vessels that carry blood away from your heart to all the parts of your body.
- Veins - blood is returned from your body to the heart.
- Arteries and Veins - specialized blood vessels are in between the arteries and veins. Diffusion of gases and nutrients happens in these specialized cells.
- Capillaries - tiny blood vessels that connect arteries to veins. One cell later is thick and extremely narrow. Helps with diffusion.
- Blood - second largest example of connective tissue. Blood consists of red blood cells, white blood cells, tiny cells called platelets-and plasma-the liquid portion of blood. Plasma makes up 55% of your blood, and the other parts make up 45%.
What is the system function of the circulatory system?
- transport oxygen, food, and other substances, throughout the body.
- transport some wastes to other organs for elimination.
- defend the body against diseases.
- connect all other organ systems.
What are the parts of the nervous system and the function of the parts?
•brain - part of the central nervous system. Receives stimuli from the outside world which are gathered by sense organs, ears, eyes, etc. Brain receives internal stimuli from inside the body. Reacts to stimuli and sends messages to certain parts of the body.
•spinal cord - connects to the brain. Part of the central nervous system. It’s a highway to carry messages between the body and the brain. It contains a type of neuron called an interneuron.
Eyes, ears, etc. - helps sense things from the outside world.
What are the functions of the nervous system?
- coordinate and control the actions of all organs and organ systems.
- detect, process, and respond to changes in external and internal environments.
What are the parts of the excretory system and the functions of the parts?
- kidneys - main organs of excretion. They filter blood and they strain out urea, water, and other salts. Produce urine. Filter every drop of blood 300 times a day. Keep the proper amount of water in your blood.
- ureters - long tubes that connect the kidneys to the bladder.
- bladder - bladder expands when urine comes. Can store 1L. When full, muscles contracts it pushes urine out through the urethra.
- lungs - gets carbon dioxide out of your body.
- skin - sweat comes out of skin. Sweat is removed from your blood.
- liver - takes highly toxic ammonia produced by the body’s cells out of the bloodstream and converts it into a less harmful substance called urea. The liver releases the urea into the bloodstreams to be disposed further of.
What is the function of the excretory system?
-remove chemical and gaseous wastes from the blood.
What is the function of the skeletal system?
- provide a moveable support frame for the body.
- protect soft-tissue organs such as the heart and lungs.
What is the muscular system function?
- move bones.
- moves organs that contain muscle tissue (such as the heart and stomach).
What is the function of the integumentary system?
- protects the body’s internal environment from the external environment.
- sense pain, pressure, and temperature.
