Digestive & Excretory System
a class of nutrients that builds body tissues and supplies energy made of amino acids.
Protein
Divides the right and left chambers of the heart
Septum
BRENDAN BRAIN FART:
tiny sacs of lung tissue specialized for the movement of gases between air and blood
Alveoli
CELLS:
liquid-filled spaces in the cytoplasm
Vacuole
What is the force of a magnet?
attracting and repelling
large muscular sac that continues the mechanical and chemical digestion of food
stomach
a blood vessel that carries blood back to the heart
vein
What do we inhale and what do we exhale?
We inhale oxygen and exhale carbon dioxide.
What's the difference between a sprain and a fracture?
A sprain is to injure a joint by twisting or tearing its muscles or ligaments while a fracture is to break or crack a bone
the region around a charged object where the object's electric(or magnetic) force interacts with other charged objects
electric field
BRENDAN BRAIN FART:
Complex carbohydrates that are composed of many sugars linked together.
Starches
the process by which molecules move from an area of higher concentration to an area of lower concentration
Diffusion
What is the path of air through the respiratory system?
Nose/Mouth --> larynx (voice box) --> trachea (windpipe) --> bronchi
What are the four stages of the water cycle?
Precipitation, Evaporation, Condensation, and Transpiration.
a material through which electric charges do not flow easily
insulator
tube leading from the urinary bladder to the outside of the body
urethra
a tiny blood vessel where substances are exchanged between the blood and the body cells
capillary
How and where is gas exchanged?
The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. Inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
What's the difference between the cerebrum and cerebellum?
The cerebrum inputs the senses, controls movement and carries out complex mental processes while the cerebellum coordinates actions of your muscles and helps keep balance.
groups of atoms with aligned magnetic poles
magnet domains
organ that removes urea, excess water, and other waste products from the blood and passes them to the ureter
kidney
The system that circulates blood and lymph through the body, consisting of the heart, blood vessels, blood, lymph, and the lymphatic vessels and glands.
Circulatory System
BRENDAN BRAIN FART:
The process in which oxygen and glucose undergo a complex series of chemical reactions inside cells
Respiration
Link between the nervous system and the endocrine system. It acts like a bridge to communicate between them. It helps maintain homeostasis.
Hypothalamus
resistance is equal to the voltage divided by the current
ohm's law
