Preguntas del test (21)
1mammals have ___ in which the blood is pumped by a powerful muscular heart and circulated in a continuous system of tubes -arteries, veins and capillaries- under pressure.
- Aa closed circulation
- Ban open circulation
2The heart is divided into four chambers and blood flows from the ___ side of the heart to the ___ and then back to the ___ side.
- Aright | lungs | left
- Bleft | lungs | right
- Cright | body | left
- Dleft | body | right
3As blood passes ___ through the heart, it is called a ___ circulation.
- Athrice | double
- Btwice | single
- Ctwice | double
- Dfour times | double
- Eonce | double
4Advantages of the circulatory system of mammals are:
- Aoxygenated blood reaches respiring tissues undiluted by deoxygenated blood.
- Bsimultaneous low-pressure delivery of oxygenated blood to all regions of the body.
- Csimultaneous high-pressure delivery of oxygenated blood to all regions of the body.
- Dthe heart is very strong and so is able to continue pumping blood.
5Blood is a special tissue consisting of a liquid medium called ___ in which ___ ( red cells), ___ (white cells) and ___ are suspended.
- Aplasma | erythrocytes | leucocytes | plates
- Bplasma | leucocytes | erythrocytes | palets
- Cplasmodium | erythrocytes | leucocytes | platelets
- Dplasma | erythrocytes | leucocytes | platelets
6The erythrocytes are in the transport of reparatory gases.
- AVerdadero

- Cundissolved proteins
- Dheat
- Eminerals
- Fdissolved proteins -antibodies
- Gdissolved proteins --with regulatory roles
- Hhormones
- Ioxygen
- Jcarbon dioxide
8Erythrocytes transport:
- Aoxygen
- Bdissolved proteins
- Ccarbon dioxide
- Dantibodies
9Lymphocytes..
- Atransport carbon dioxide
- Bform antibodies
- Cfight antibodies
10Phagocytes..
- Aform bacteria
- Bform antibodies
- Cingest bacteria
11platelets..
- Aform antibodies
- Bplay a part in the blood clotting mechanism
- Ctransport various substances to body cells
12Arteries carry blood to the heart.
- AVerdadero
- BFalso
13Arteries carry blood away from the heart and veins do the opposite.
- AVerdadero
- BFalso
14Capillaries are..
- Afine networks of tiny tubules linking arteries and veins.
- Bfine network of large tubules separating arteries and veins.
15Both arteries and veins have strong walls, but the walls in veins are much thicker and stronger.
- AVerdadero
- BFalso
16In comparison to arteries and veins where the walls are strong due to the presence of ___ , capillaries' walls only consist of ___.
- Acollagen fibres | endothelium
- Bendothelium | collagen fibres
- Ccollage fibres | endothelial cells
- Depithelial fibres | endothelium
17Veins have valves at intersections to prevent backflow.
- AVerdadero
- BFalso
18The ___ side of the heart pumps ___ blood to the ___, and the arteries, veins and capillaries serving the ___ are known as ___ circulation.
- Aleft | deoxygenated | lungs | lungs | pulmonary
- Bright | oxygenated | body | body | pulmonary
- Cright | deoxygenated | lungs | lungs | pulmonary
19Arteries, veins and capillaries serving the ___ side of the heart by taking blood to ___ are known as the ___ circulation.
- Aright | body cells | systemic
- Bright | body cells | pulmonary
- Cright | the lungs | systemic
20arteries connect to the main ___ and veins join the ___ carrying blog back to the heart.
- Aaorta | vena cava
- Bvena cava | aorta
- Csemi luna valves
21The branching sequence for circulation is:
- Aartery > aorta > arteriole > capillary > venule > vein > semi lunar valve
- Baorta > artery > arteriole > capillary > venule > vein > vena cava
- Cvena cava > vein > venule > capillary > arteriole > aorta > artery
- Daorta > artery > venule > capillary > arteriole > vein > vena cava
