Digestive/Respiratory System
What are all of the functions of the respiratory system
1.provides O2
2.eliminates CO2
3. regulates blood pH [H+] (based on this, the autonomic nervous system regulates breathing)
4. forms speech sounds
5. defends against microbes
What are the lymphoid organs?
Organs that have lots of immune cells (eg. bone marrow, thymus, lymph nodes, spleen, tonsils)
Label the heart
See circulatory slideshow
What is the net charge of a resting electron?
-70 millivolts compared to the outside environment.
Make a flowchart of al of the parts of the nervous system
Nervous System
Peripheral & Central
Peripheral: Autonomic and Somatic
Autonomic: Sympathetic (arousing), Parasympathetic (calming)
Somatic: Sensory input and Motor output (controls skeletal muscles)
Write out the process of the mass exchange
Nasal cavity → larynx → trachea → lungs → bronchi → bronchioles → alveoli (air sacs) = where gas exchange occurs → blood → cells
What is the development of lymphocytes called
Hematopoiesis
What happens in the capillaries, and what are their dimensions?
one cell thick & ~ 1 blood cell wide
diffusion & osmosis occurs across walls into cells that make up vital organs
What are the 3 types of neurons, what do they do, and what do they look like?
Sensory: receives impulse
Interneuron/Relay neuron (only in the brain): transports signal from sensory to motor neuron
Motor neuron: passes down impulse based on the decision of how to react, causing muscles to contract of expand, creating movement.
What was the first vaccine and how was it given?
Against small-pox, they would take some of the puss from a relatives wound and shoot it up your nose, or rub it into incisions.
What does the pancreas do?
The pancreas produces digestive enzymes. These include amylase, which breaks down carbohydrates, trypsin, which breaks down proteins, and lipase, which breaks down fats. The pancreas also produces an alkaline solution that neutralizes acid.
What forms the upper arm
The upper arm is formed by one long bone, the humerus. The top end of the humerus is rounded and fits into a cup-shaped depression in the scapula, or shoulder bone, forming a ball-and-socket joint. Ball-and-socket joints allow for circular movement.
What do nephrons do?
What is the function of the nervous system
The nervous system collects information about the body's internal and external environment, processes that information, and responds to it.
give an example of a drug and how it alters the brain
See drug assignment
What does the large intestine do?
Water and vitamin K are absorbed from food that passes through the large intestine.
Bacteria help to break down fiber and other materials.
Draw an arm with and label musculoskeletal components
See musculoskeletal slideshow
What is the molecular structure of amino acids, and what changes as they are broken down into ammonia?
H - O
| ||
H-N -C - OH
Turns to
H-N-H

What is fearmongering, and how does it weigh against risks of an individual? What about society?
See notebook
What are capillaries and what do they in the digestive system?
Capillaries are tiny blood vessels that transport absorbed monosaccharides, amino acids, and water to the bloodstream. The nutrients are then carried to body cells.
How does the human arm move (use all terms)
The brain tells the muscles to contract or expand, and then the tendons pull on the bones, which keeps them steady, and then the joints allow up and down movement
Order the following:
A) Waste is extracted by nephrons
B) Blood enters the kidneys
C) Urine enters the urethra
D) Urine passes through the ureters
E) Urine is stored in the bladder
B, A, D, E, C
