Lysosomes
are small vesicles made of biomembrane
contain digestive enzymes
contain enzymes capable of cleaving certain substances
are a permanent membrane organ of eukaryotic animal cells
their enzymes decompose some of the substances taken into the cells
The phases of mitotic division in eukaryotic cells include:
prophase
metaphase
anaphase
telophase
Cells with one chromosome set are called:
haploid
gametes
oogonia
Cell wall of a eukaryotic cell may include
chitin, cellulose, lignin, salts and wax
Where are the nuclear pores in eukaryotic cells
in the nuclear envelope of the eukaryotic cell
the human colon:
(a) no digestive juices are released into it
b) there is limited absorption - e.g. water
(d) bacteria in it produce B-complex vitamins and K vitamin
f) the activity of bacteria generates gases that stretch its wall and stimulate its activity
h) bacterial activity produces toxic substances that are degraded in the liver
The human forebrain:
contains the basal ganglia, which are formed by the clumps of grey matter
contains the basal ganglia involved in motion management
d) contains the cerebral cortex that is folded
e) contains the cerebral cortex that is folded into ridges and grooves
contains the cerebral cortex where consciousness is formed
Human teeth:
[a) are found in the oral cavity
b) are important for speech
there are 32 teeth
are important for mastication
are located in the mandible
The urinary bladder in humans:
a) is located behind the symphysis
b) urine is stored in it/stores urine
c) is emptied by contraction of smooth muscle fibres in its wall
d) accumulates from 500 to 700 ml of urine
Breathing:
a) is a complex function involving special organs
b) oxygen is taken in and carbon dioxide is released
c) breathing muscles are involved
d) blood and blood circulation are involved
e) is controlled by the central nervous system
To determine the sharpness of vision, we use the:
Snellen’s optotypes
Blood transfusion:
b) saves a life by great blood loss
[c) delivers blood cells and important substances
d) supplements the lost volume of circulating blood
today is mostly provided with blood packs
h) to prevent severe damage or death, it is best if the donor and the recipient have the same blood group
How many deciduous teeth do humans have?
20
Through which parts of the circulatory system does blood pass after it leaves the
right ventricle?
pulmonary arteries and capillaries, pulmonary veins, left atrium, left ventricle, aorta, smaller arteries, capillaries, veins, upper (lower) vein and right atrium
The parts of the excretory system in a healthy human are:
c) one urethra and two ureters
d) a single ureter emerges from each renal pelvis
the ureters leading to the bladder
the kidney as a paired organ located behind the peritoneum
The human skeleton:
forms a moving body support
b) is threaded with joint synovia
the skeleton of the limbs consists of the cingulum and extremity
After fertilization in normal human ontogenesis follows:
a) the zygote division
b) transporting the egg into the uterine cavity by moving the egg duct and its rib linings
c) germination of the embryo in the uterus (3-4 days after fertilization)
e) menstrual bleeding
d) the formation of progesterone, which maintains the secretory phase of the uterine mucosa
Which statement about the human forearm muscles is true?
some begin on the shoulder bone
some begin on the bones of the forearm
their tendons reach to the skeleton of their hands
The human forebrain:
a) is covered with the cerebral cortex
b) it includes the cerebral cortex - the pallium
consists of brain hemispheres
The muscles of the abdomen in man:
form a flexible abdominal wall

e) promote stomach emptying when vomiting
f) promote foetal ejection at birth
g) are working in the bends
h) are working in the bow and turn the body
Synovia in a healthy joint:
nourishes the cartilage
is an important part of the joint
reduces friction
Sleep:
is a basic physiological phenomenon
has a positive effect on the whole body
