All living things are composed of basic units called [blank_start]__________[blank_end]. Groups of similar cells form [blank_start]_____________[blank_end]. Groups of tissues working together to perform a particular function are called [blank_start]____________[blank_end]. Groups of organs that work together are called organ [blank_start]____________[blank_end].
Every cell in the body carries out a process called [blank_start]__________________.[blank_end] This process needs [blank_start]_____________[blank_end] and sugar to produce [blank_start]________[blank_end] and [blank_start]_________ __________[blank_end].

A correct definition and example of mechanical digestion is...
Digestion that involves physically breaking down food. Examples are the stomach gurgling and the vili moving.
Digestion that involves acids and enzymes to break down food. Examples are peristalsis and the lower intestine churning.
Digestion that involves physically breaking down food. Examples are chewing food (Mastication) and the stomach churning.
Digestion that involves acids and enzymes to break down food. Examples are chewing food and the stomach churning.
A correct definition and example of chemical digestion is...
Digestion that involves chemically breaking down food. Examples are enzymes in the saliva in your mouth and enzymes and acid in your stomach.
Digestion that involves chemically breaking down food. Examples are enzymes in food which are released after you break food particles so that food digests itself and leaves all the nutrients for your body.
Digestion that involves nuclear fusion to split the atoms of your food. Examples are CERN and other LHC facilities.
Digestion that involves physically breaking down food. Examples are chewing food and the stomach churning.
The main acid found in the stomach is...
HCl (That is an L btw)
Stomach walls are so [blank_start]thick[blank_end] so that acid cannot [blank_start]build-up[blank_end]
make it blue
eat away the flesh

The correct order that food goes through in your digestive system is:
[blank_start]Mouth[blank_end], [blank_start]Esophagus[blank_end], [blank_start]Stomach[blank_end], [blank_start]Small Intestine[blank_end], [blank_start]Large Intestine[blank_end], [blank_start]Rectum[blank_end] and [blank_start]Anus[blank_end]
Which of the following are parts of the circulatory system?
There are five types of blood vessels in our bodies: arteries, [blank_start]arterioles[blank_end], venules, [blank_start]veins[blank_end] and [blank_start]capillaries[blank_end].
Arteries and arterioles carry blood from the heart to the [blank_start]body[blank_end]. They carry [blank_start]oxygenated[blank_end] blood (except the pulmonary artery). They have thick, muscular walls (Lesser so of the arterioles) that are able to withstand [blank_start]high[blank_end] pressures. Veins and [blank_start]venules[blank_end] carry blood from the [blank_start]body[blank_end] back to the heart. They carry [blank_start]deoxygenated[blank_end] blood (except the pulmonary veins). Veins and venules have [blank_start]thin[blank_end] walls, and valves to stop blood flowing backwards. Capillaries are tiny blood vessels. They have the thinnest [blank_start]walls[blank_end] (1 cell thick), that allow [blank_start]oxygen[blank_end] and carbon dioxide to pass into and out of the bloodstream.
Correctly label the parts of the respiratory system
Excretion is the process of removing unwanted [blank_start]cellular[blank_end] waste from the body. The main organs of the excretory system are the [blank_start]kidneys[blank_end]. These organs filter wastes like urea and excess [blank_start]salts[blank_end] and water from the body. This waste then travels down the [blank_start]ureter[blank_end] to the bladder. When the bladder is full, urine is expelled from the body via the [blank_start]urethra[blank_end].
The main function of the human urinary system is to remove urine (OMG I didn't know that!). Urine contains excess [blank_start]salts[blank_end], excessive [blank_start]water[blank_end] and [blank_start]nitrogenous[blank_end] wastes which include urea which is a by product of breaking down [blank_start]ammonia[blank_end],
