Kin 2YY3 Exam Questions With Complete Solutions
"dubb" Correct Answers Second heart sound indicating the
closure of the semilunar valves. Occurs at the beginning of
ventricular diastole
"lubb" Correct Answers First heart sound indicating the
closure of the AV valve. Occurs at the beginning of ventricular
systole
3 Different types of propulsion in the digestive system Correct
Answers 1. Mixing
2. Peristalsis
3. Swallowing
Absolute refractory period Correct Answers Cardiac muscle is
completely insensitive to further stimulation
Active ventricular filling Correct Answers Atria contracts due
to depolarization from the SA node. Blood is pushed through the
AV valve into the ventricles, and to ensure all the blood is
pushed out from the atria, there is a short delay
Adam's apple Correct Answers Growth of thyroid cartilage
Adenoids Correct Answers Found in the nasopharynx and are
involved in the immune system
Afterload Correct Answers Pressure the contracting ventricles
must produce to overcome the pressure in the aorta and send
blood through the semilunar valve
,Agranulocytes Correct Answers Small and non-lobed; 2
different types
1. Lymphocytes
2. Monocytes
Albumin Correct Answers Carries substances in blood and is
responsible for maintaining osmotic pressure of the blood to
ensure not too much fluid is lost/gained
Alveolar ducts Correct Answers Acts as a hallway to alveolar
sacs and are lined with alveoli; consists of elastic tissue so it can
expand
Alveoli cell types Correct Answers 1. Type I pneuomocyte
2. Type II pneumocyte
3. Macrophage
Anastomoses Correct Answers Connections between arteries
and can provide an alternative route if an artery becomes
occluded
Aortic arch Correct Answers Has 3 branches
1. Brachiocephalic artery
2. Left common carotid
3. Left subclavian artery
Apex of the heart Correct Answers Blunt, pointed end of the
heart; inferior
,Arteries Correct Answers Carries blood away from the heart;
has larger walls than veins and are more elastic
Arteries of the upper limb (shoulder to hand) Correct Answers
1. Shoulder region: Subclavian artery
2. Passes clavicle: Axillary artery
3. Bicep region: Brachial artery
4. Forearm: Ulnar and radial arteries
Arterioles Correct Answers Transports blood from small artery
into capillaries and is the smallest blood vessel where the 3
general layers can be differentiated
Arytenoid cartilage Correct Answers Controls the folds of the
vocal cords to create the different pitch levels
Atrioventricular (AV) nde Correct Answers AP is slowed
down here to ensure that ventricles receive the signal to contract
after the atria have fully contracted. Found near the right atrium.
Autorythmicity Correct Answers Capable of self-
depolarization where AP is generated at regular intervals
AV bundle Correct Answers Gateway between the SA and AV
nodes and conducts AP much quicker than normal here. Also
known as the Bundle of His. Found between the ventricles and
splits into left and right bundles
Azygos vein Correct Answers Drains into superior vena cava
and gathers blood from the hemiazygos vein
, Baroreceptors Correct Answers Monitors stretch on walls of
vessels and sends signals to the brain
Base of the heart Correct Answers Flat end of the heart,
superior
Basilar artery Correct Answers Supplies cerebellum and pons
Basophils Correct Answers Type of WBC; Produces histamine
and heparin; functions as an antagonist to eosinophils
Best way to change resistance Correct Answers
Increase/decrease diameter
Bicuspid valve Correct Answers An AV valve located
between the left atrium and left ventricle; also called mitral
valve
Bilirubin Correct Answers Converted from iron-free heme and
is carried to the liver via albumin; its derivatives are responsible
for the brown tint in feces and yellow tint in urine
Boyle's Law Correct Answers Pressure is inversely
proportional to volume
Boyle's Law Correct Answers Pressure is inversely
proportional to volume
Used by lungs to decrease/increase pressure in lungs
