Body Systems Revision

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...

A correct definition and example of chemical digestion is...

The main acid found in the stomach is...

Stomach walls are so [blank_start]thick[blank_end] so that acid cannot [blank_start]build-up[blank_end]

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?

Label the parts of the heart correctly

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],

Correctly label the urinary system
