9.1&9.2 Transport in Animals Quiz

Match the term to its description.

• force blood out of the heart

• valves

• keep blood flowing in one direction

• ventricles

• largest artery in the body

• blood pressure

• blood, blood vessels and heart

• circulatory system

• force of blood pushing against vessels

• aorta

Which of the following does not have valves

• Heart

• Arteries

• nerves

• veins

Answer explanation

Arteries do not have valves, as they carry blood away from the heart under high pressure. In contrast, veins and the heart contain valves to prevent backflow, while capillaries are too small to have valves.

3) Where does the maximum exchange of materials between blood and surrounding cells occurs?

• Heart

• Veins

• Arteries

• Capillaries

Answer explanation

The maximum exchange of materials between blood and surrounding cells occurs in the capillaries. Their thin walls and extensive surface area facilitate the diffusion of oxygen, nutrients, and waste products.

what does an atrium do

• let blood in

• let blood out

• exchange gases

• remove waste

Answer explanation

The atrium is a chamber of the heart that receives blood from the body and lungs. Its primary function is to let blood in, either from the body (right atrium) or from the lungs (left atrium), before it moves to the ventricles.

what does a ventricle do

• force blood out

• let blood in

• exchange gases

• remove waste

Answer explanation

The ventricle is a chamber of the heart that contracts to force blood out into the arteries, delivering oxygenated blood to the body and deoxygenated blood to the lungs. Thus, the correct answer is 'force blood out'.

what is the purpose of circulation

• supply O2 and nutrients and remove waste

• break down the food

• get oxygen into the lungs

• remove solid waste

Answer explanation

The purpose of circulation is to supply oxygen (O2) and nutrients to cells while removing waste products. This is essential for maintaining cellular function and overall health, making it the correct choice.

left side of the heart is high in

• O2

• CO2

• N

• H

Answer explanation

The left side of the heart pumps oxygenated blood to the body, making it high in O2. In contrast, the right side receives deoxygenated blood, which is high in CO2. Therefore, the correct answer is O2.

what is the function of arteries/arterioles

• take blood to heart

• take blood away from heart

• take blood to colon

• take blood to brain

Answer explanation

Arteries and arterioles are responsible for carrying blood away from the heart to various parts of the body. This is essential for delivering oxygen and nutrients, making 'take blood away from heart' the correct choice.

what is the function of the veins/venuoles

• take blood toward heart

• take blood away from heart

• remove waste

• take blood to stomach

Answer explanation

Veins and venules are responsible for carrying deoxygenated blood back to the heart. This is why the correct answer is 'take blood toward heart', as they play a crucial role in the circulatory system.

what happens in systemic circulation

• circulation for the entire body

• circulation in the heart only

• circulation heart and lungs

• circulation to digestion system only

Answer explanation

Systemic circulation refers to the flow of blood throughout the entire body, delivering oxygen and nutrients to tissues and organs, and returning deoxygenated blood to the heart. Thus, the correct choice is 'circulation for the entire body'.
