Hierarchy of Organization
In animals, cells are grouped into tissues. Tissues combine to form Organs. Organs are organized into Organ Systems. Organ Systems make up the entire Organism.
Loose Connective Tissue
The most widespread connective tissue. It binds the EPITHELIA to underlying tissues and holds ORGANS in place.
Found in the brain and spinal cord. Makes the communication of the sensory information possible. Sensory input is received and processed, then motor output is relayed to make body parts respond. The basic unit is the neuron/nerve cell
Consists of 2 or more tissues that performs a specific function. (e.g. heart, liver, stomach, etc.)
Mechanical digestion - physical processes (chewing), Chemical digestion - breakdown of food by digestive enzymes. Digestive tubes - mouth and anus.
Human Digestive system
Consists of the alimentary canal and organs that secrete digestive chemicals.
The longest part of the alimentary canal. The major organ for chemical digestion and absorption.
A central pump (heart), vascular system (blood vessels), circulating fluid (blood).
White Blood Cells
Fight infections and cancer. AKA leukocytes. 700 times fewer than red blood cells.
Most common respiratory surface of terrestrial organisms. The circulatory system transport oxygen from the respiratory surface to the rest of the body. Air moves through the body from the mouth/nose to the bronchioles.
Which best describes the function of the kidneys?
Filtering blood, removing wastes and regulating water balance.
Major segments of the alimentary canal in the correct order.
Oral cavity, esophagus, stomach, small intestine, large intestine
Role of the atrioventricular valves in the heart
Allow blood to flow from the atria into the ventricles and to precent the blood from flowing back into the artia while the ventricles contract
Sequence that air passes through during breathing after it enters the mouth and nose...
pharynx, larynx, trachea, bronchi, bronchioles, alveoli
Order of passage as air is inhaled into the lungs
nasal cavity, pharynx, larynx, trachea, bronchiole, alveolus
