a cell that carries nerve impulse information
3 parts of a neuron
dendrites, cell body, and axon
Nerve cells have a space between them called a _____________.
The function of the nervous system is to ___________ & _____________ to information from inside and outside of the body.
receive and respond
There are two parts to the nervous system:
1. _________________ nervous system
2. ________________ nervous system
1. central nervous system
2. peripheral nervous system
The ___________ nervous system includes the brain and spinal cord.
The _______________ nervous system includes all nerves branching from the CNS to the body.
Performs everyday voluntary (movements you choose to carry out) tasks such as walking and writing. Helps us stay balanced and upright along with coordinating our muscles.
comprised of the midbrain, pons, and medulla
It is involved in sensory perception, controlling sleep and awake states of consciousness. It also regulates movement
This "master gland" regulates how your other glands operate. The _____________ __________ secretes and stores hormones, which it uses to stimulate your other glands. Hormones regulate your body's temperature, urine production, growth, and the production of sex hormones
A long, thin bundle of nervous tissue that extends from the brain. Makes up part of the central nervous system. Transmits signals between the brain and the rest of the body. By itself, it can control numerous reflexes.
three types of circulation
coronary, pulmonary, systemic
arteries and veins supply the heart with blood (type of circulation)
pulmonary artery carries deoxygenated blood to the lungs to release CO2 and pulmonary vein carries oxygenated blood back to the heart (type of circulation)
arteries bring oxygenated blood to body cells and veins return deoxygenated blood back to heart (type of circulation)
3 functions of the circulatory system
1. Carry nutrients & oxygen to cells & waste and carbon dioxide away from cells
2. Contains cells that fight disease
3 Includes heart, blood vessels, blood
The heart pumps blood to all parts of the body and has _________ chambers
The upper two chambers that receive blood are called the __________.
The lower two chambers that pump blood
Three types of blood vessels
arteries, veins, capillaries
_______________ carry oxygen-rich blood AWAY FROM heart to body.
_____________ carry oxygen-poor blood from body BACK TO heart
_____________________ microscopic blood vessels connect arteries to veins (only ONE CELL THICK!!)
____________ and __________ diffuse into body cells
__________ and ____________ __________ diffuse out of body cells
nutrients and oxygen, waste and carbon dioxide
parts of blood
Plasma, red blood cells, white blood cells, platelets
"watery" part of blood that carries nutrients, minerals, oxygen to cells and carries waste away
red blood cells
made in the bone marrow, these cells carry oxygen to body cells using an iron-containing protein called hemoglobin
white blood cells
made in the bone marrow, these cells fight bacteria and viruses
cell fragments that help in the process of clotting
The function of the respiratory system is to exchange ___________ and ___________ ___________ with the external environment and your internal environment
oxygen, carbon dioxide
parts of the respiratory system
nose, mouth, phayrnx, larynx, trachea (windpipe), lungs
These tiny sacs, called _____________, in the lungs, are surrounded by capillaries (oxygen enters bloodstream and carbon dioxide exits).
In the alveoli, ____________ enters bloodstream and _____________ ______________ exits.
oxygen, carbon dioxide
Inhale - Diaphragm - muscle moves down/lungs expand
Exhale - Air moves out automatically
Cellular respiration: chemical reaction that uses oxygen to release energy from food.
two parts to respiration
A sheet of internal skeletal muscle that extends across the bottom of the thoracic cavity (heart/lungs)
Pulls and pushes against the lungs as we inhale and exhale
Separates thoracic cavity from abdominal cavity
The passage that leads from the cavities of the nose and mouth to the larynx.
Both food and air pass through here, so it's part of BOTH the respiratory and digestive systems.
hollow muscular organ which holds the vocal cords (voice box) which produce sound
a flap of elastic cartilage attached to the larynx that closes when food passes by
A hollow tube (wind pipe) that connects the larynx to the right and left bronchus.
the two major air passageways leading from the trachea to the lungs
the smallest air passageways coming off of the bronchi
the airs sacs at the end of the bronchioles where the gas exchange takes place (oxygen in and carbon dioxide out)
Control the flow of blood through the heart by opening and closing during contractions
Allows blood to flow in only one direction
valves of the heart
A muscular organ about the size of a fist
