QUIZ
#2: Circulatory & Respiratory Systems
(30
marks… including 1 mark for showing up today)
1) List the four components of
blood (4 marks):
- Plasma
- Erythrocytes/ Red Blood Cells
- Leukocytes/ White Blood Cells
- Platelets
2) Fill in the blank with the
appropriate term from the list below. (8 marks)
left
atrium, tricuspid valve, aorta, pulmonary vein, septum, pulmonary artery, right
ventricle, inferior vena cava, right atrium, left ventricle, superior vena cava
left atrium: receives
oxygen-rich blood from the lungs via the pulmonary vein
pulmonary artery: the blood vessel that carries
oxygen-poor blood from the right ventricle of the heart to the lungs
pulmonary vein: the blood
vessel that carries oxygen-rich blood from the lungs to the left atrium of the
heart
right ventricle: pumps the
blood into the pulmonary artery
tricuspid valve: the flaps between the right
atrium and the right ventricle. It is composed of three leaf-like parts and
prevents the back-flow of blood from the ventricle to the atrium
aorta: carries oxygen-rich
blood from the left ventricle of the heart to the body
inferior vena cava: a large
vein (a blood vessel carrying blood to the heart) that carries oxygen-poor
blood to the right atrium from the lower half of the body
septum: the muscular wall
that separates the left and right sides of the heart
4) Complete the statements below (4
marks):
During inhalation, the diaphragm contracts/moves
down
During exhalation, the diaphragm relaxes/moves
up
During inhalation, oxygen
gas is brought into the body.
During exhalation, carbon
dioxide gas is expelled from the body.
5) Name on similarity and one
difference between the human and fish or frog (2 marks).
Similarity: Frog – pharynx,
esophagus, lungs, bronchus
Fish
– atrium, ventricle; closed system; blood flows atrium to ventricle
Difference: Frog – gills; gulp air;
use moist skin; chest doesn’t expand
Fish
– 2 chambers, gills for oxygen; one system; one circuit
7) Match the following terms to
their explanation: Bronchitis, Bronchial Asthma, Carbon Monoxide Poisoning (3
marks): *Read carefully as you can only use each term once!
Bronchial Asthma: Shortness
of breath, coughing, wheezing (due to narrowing of the air passageways)
Carbon Monoxide Poisoning:
Nausea, headaches, dizziness, confusion, loss of consciousness
Bronchitis: Inflammation of
the bronchi and bronchioles (virus)
Name:

Digestive & Excretory Systems
(total of
25 marks - 1 mark for showing up)
1) Label the following diagram (5
marks):
(ureter, urinary
bladder, urethra, kidney, urethral sphincter)
2)
List
the three ways that the human and fish excretory systems differ (3 marks):
·
Removal of ammonia
·
Salt/water regulation
· Urine release
3)
Define
the following (4 marks):
a. Ingestion: taking in of nutrients
b. Digestion: the breakdown of complex
organic molecules into smaller components by physical and chemical means
c. Absorption: the taking up of
digested molecules into the cells of the digestive tract
d. Egestion: the removal of waste food
materials from the body
4)
Match
the following terms to their function below (10 marks):
( mouth, epiglottis, esophagus, liver, stomach,
pancreas, gallbladder, small intestine, large intestine, rectum, anus)
Anus: where solid waste is expelled from the body
Mouth: involved in physical and chemical breakdown of
food
Liver: produces bile
Esophagus: wave like movement brings food to
stomach
Pancreas: produces enzymes for breakdown of
macromolecules in a juice
Epiglottis: directs food away from trachea
Gallbladder: concentrates the bile and stores
until needed
Small intestine: nutrients are absorbed
Large intestine: water is absorbed and bolus becomes
feces
Rectum: storage of solid waste until expelled
5)
What
causes diarrhea? (2 marks)
–peristalsis occurs to quickly
–water is not absorbed in the large intestine
