Respiration of Fishes
gills
acquire oxygen and release carbon dioxide and is mostly
associated with the circulatory system
respiratory system
Respiration of Annelids
skin
Respiration of Vertebrate
lungs/alveoli
Respiration of Insects
tracheal system
Route of air through the respiratory system
nose → nasal cavity → pharynx → larynx → trachea → bronchi → bronchioles → alveoli
Common Respiratory Diseases
Asthma
Emphysema
Tuberculosis
A chronic inflammatory disease that causes breathing problems due to narrowed
airways from inflammation or mucus blockage.
Asthma
sacs (alveoli) lose elasticity and become damaged, reducing the lung’s ability to
transfer oxygen to the blood.
Emphysema
Caused by Mycobacterium tuberculosis, spreads through airborne germs from
person to person.
Tuberculosis
can occur in roots, stems, and primarily in leaves.
Gas exchange
are tiny pores in plant tissue that open and close to enable gas exchange which helps
in photosynthesis.
Stomata
control the opening and
closing of the stomata.
guard cells
When the _______are _____, the guard cells are swollen and when it is
_____, the guard cells are shrunken.
stomata ; open
closed
carries water and nutrients
Xylem
carries food and other organic substances ( e.g. hormones and mRNA)
Phloem
Types of Immune System
Innate Immunity and Adaptive Immunity
is the host’s first line of defense and is intended to prevent infection and attack the invading pathogens.
Innate Immunity
Examples of Innate Immunity
Neutrophils, Macrophage, Dendritic Cells, Natural Killer Cells
involves specialized immune cells and antibodies that attack and destroy
foreign invaders and are able to prevent disease in the future by remembering what those substances
look like and mounting a new immune response. examples: B and T cells
Adaptive Immunity
Nervous System Types
Central Nervous System
Peripheral Nervous System
Somatic Nervous System
Autonomic Nervous System
brain and spinal cord
Central Nervous System
cranial nerves and spinal nerves that carry information in and out of the CNS.
Peripheral Nervous System
allows us to consciously, or voluntarily, control our skeletal muscles.
Somatic Nervous System
regulates events that are automatic, or involuntary, such as the activity
of smooth and cardiac muscles and glands.
Autonomic Nervous System
conveys impulses to the central nervous system from sensory receptors located in
various parts of the body.
Sensory (afferent)
carries impulses from the CNS to effector organs, muscles, and glands. These
impulses activate muscles and glands.
Motor (efferent)
responds to stress and is responsible for the increase of your heartbeat and blood
pressure, among other physiological changes, along with the sense of excitement you may feel due to
the increase of adrenaline in your system.
Sympathetic
is evident when you rest or feel relaxed and is responsible for such things as the
constriction of the pupil, the slowing of the heart, the dilation of the blood vessels, and the stimulation
of the digestive and urinary systems.
Parasympathetic
It receives information from our senses and controls our thoughts and movements.
Brain
Parts of the Brain
Diencephalon/interbrain
Brain Stem
Cerebellum
Cerebrum
Left Hemisphere
Right Hemisphere
Parts of Diencephalon/interbrain
Thalamus
Hypothalamus
relay station for sensory impulses passing upward to the sensory cortex.
Thalamus
All information from your body’s senses (except smell) must be processed through your ________ before being sent to your brain’s cerebral cortex for interpretation.
Thalamus
plays a role in sleep, wakefulness, consciousness, learning and memory.
Thalamus
important autonomic nervous system center because it plays a role in the regulation of
body temperature, water balance, and metabolism.
Hypothalamus
the center for many drives and emotions For example, thirst, appetite, sex, pain, and
pleasure centers are in the hypothalamus.
Hypothalamus
Parts of Brain Stem
Midbrain
Medulla Oblongata
Pons
relay system, transmitting information necessary for vision and hearing.
Midbrain
plays an important role in motor movement, pain, and the sleep/wake cycle.
