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.
The study of the structure of an organism
Study of the function of an organism's structural equipment
Group of similar cells that perform a specific function
Covers the surface of the body and lines organs and cavities within the body
Loose Connective Tissue
The most widespread connective tissue. It binds the EPITHELIA to underlying tissues and holds ORGANS in place.
Stores fat, stockpiles energy, pads and insulates the body.
Is a connective tissue. Red and White blood cells is suspended in plasma.
Connective tissue that forms tendons and ligaments.
Forms the shock-absorbing pads that cushion the vertebrae of the spinal column.
Connective tissue with rubbery fibers that harden with deposits of calcium.
Responsible for voluntary movements. It is attached to bones by tendons
Its' contraction accounts for the heartbeat
Found in the walls of various organs and is involuntary.
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.)
Teams of organs that work together to perform vital bodily functions.
Secretes hormones that regulate the body.
Supports body and anchors muscles.
Transports substances throughout body.
Exchanges O2 and CO2 between blood and air.
Protects body. (Hair, nails, skin)
Rids body of certain wastes.
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.
Churns food into a thick soup called ACID CHYME.
The longest part of the alimentary canal. The major organ for chemical digestion and absorption.
Contains villi and microvilli, which provide a large surface area for absorption.
Absorbs water from the alimentary canal and produces feces.
Break down food molecules in cellular respiration and generate many molecules of ATP.
The rate energy consumption per day.
A central pump (heart), vascular system (blood vessels), circulating fluid (blood).
Carries blood between the heart and the lungs. (Heart to lungs and back)
Carries blood between the heart and the rest of the body. (Heart to body and back)
Carry blood toward the heart.
Allow for exchange between the bloodstream and tissue cells.
White Blood Cells
Fight infections and cancer. AKA leukocytes. 700 times fewer than red blood cells.
Surface must be large enough to take up oxygen for every cell in the body.
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.
Dead-end in clusters of air sacs called alveoli.
Carry out the process of gas exchange in the lungs.
Kills 440,000 of Americans every year.

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
Deoxygenated blood is delivered to the heart through
The superior and inferior vena cavae
Sequence of blood flow
atrium, ventricle, artery, arteriole, capillary, venule, vein
Blood cells containing hemoglobin, an iron-containing protein that transport oxygen.
Sequence that air passes through during breathing after it enters the mouth and nose...
pharynx, larynx, trachea, bronchi, bronchioles, alveoli
the diaphragm and rib muscles contract
protein that can bind 4 molecules of oxygen
Order of passage as air is inhaled into the lungs
nasal cavity, pharynx, larynx, trachea, bronchiole, alveolus
Red blood cells
