Animal Biology

what does the image above show?

• the structure of the lungs

• the digestive system

• the skeletal system

what is the function of what is shown here?

• circulates blood around the body transporting essential nutrients and gases to all tisues.

• filters and cleans the blood removing waste products in the form of urine.

• takes in oxygen and exhales carbon dioxide. allows the process of gaseous exchange.

• holds the entire body in place and allows movement by contracting and relaxing.

what is this diagram showing and what is the function?

• shows the skeletal system - holds the entire body in place and allows movement by relaxing and contracting.

• shows the endocrine glands - allows animals to reproduce and pass on its genetic material. prevents the species from going extinct.

• shows the digestive system - facilitates in the taking in, breaking down and utilising of nutrients and excretes excess waste.

• shows the endocrine glands - produces, stores and releases hormones which are messages sent around the body to affect a reaction.

what makes something a living organism?

• movement and respiration

• sensitivity and nutrients

• excretion and growth

• reproduction

• none of the above

in which order is the cell organised?

• system, cell, tissue, organ

• cell, organ, tissue, system

• cell, organ, tissue, system

• cell, tissue, organ, system

• organ, tissue, system, cell

what is the formation of blood?

(a)  

what is included in the circulatory system?

• heart

• blood vessels (veins, arteries, capillaries)

• blood

blood is taken from the heart from where and via what?

• taken from the right ventricle via the aorta

• taken from left atrium via the aorta

• taken from the left atrium via the vena cava

• taken from the left ventricle via the aorta

• taken from the right atrium via the superior vena cava

what properties does a vein have?

• carries blood towards the heart

• thin, elastic, muscular walls

• large lumen

• contains valves

• does not contain any valves

what properties does a capillary have?

• 1 cell thick

• connects venue (veins) to arteriole (arteries)

• required for diffusion of oxygen
