Name all 8 body systems
Skeletal, Muscular, Circulatory, Respiratory, Digestive, Excretory, Nervous and Homeostasis & Endocrine System
What are the 3 types of muscle?
Skeletal, Smooth and Muscular
What do you call contractions of smooth muscle in digestive system?
Where do you find the smooth muscle?
In your organs
Where do you find the cardiac muscle?
In your heart
Where do you find the skeletal muscle?
around your bones
What types of muscles are under voluntary control?
Which types of muscles are under involuntary control?
Smooth and Cardiac Muscles
How do your skeletal muscles work?
The flexors contract to bend a joint while the extensors allow a joint to straighten
What is a tendon?
Strong connective tissue
Name the four main types of joints
Pivot, Gliding, Hinge, and Ball & Socket joint
Example of a Pivot joint
Example of a Gliding Joint
Example of a Hinge Joint
Example of Ball & Socket Joint
Shoulders or hips
What are ligaments?
They join the joints together. Also bones are attached by ligaments.
What are 5 functions of the Skeletal system?
To support the body and give it shape To work with the muscles to move To protect your internal organs To store fat and other minerals To make blood cells
What is the basic unit of the Nervous System?
To recieve information also it controls functions and responses.
What are the parts of the Neuron?
Dandrites, Cell Body, Axon, Myelin Sheeth, and Axon Tips
space between two neurons
chemicals that transmit information from one neuron to another
3 parts of the Brain
cerebrum, cerebellum, and brainstem
Function of the Cerebrum
Cordinates thinking, learning, creativity, the 5 senses, memory, education, problem solving, decisions, language, communication, and body movements.
Function of the Cerebellum
Coordination of movement, fine movement, balance, position sense (proprioception) and integration of sensory input.
Function of the Brain Stem
Connects brain to spinal cord. Cordinates involuntary actions.
What cells make up antibodies?
White blood cells
Order the way the air enters the body
Nose -> Pharnyx -> Trachea -> Bronchus -> Bronchial Tubes -> Bronchioles -> Alveoli
Prevents food from entering the trachea
Why does the trachea have rings of cartliage around it?
After air enters and alveolus , oxygen passes throught the wall of the alveolus and then throught the capillary wall into the blood . Carbon dioxide and water pass from the blood into the alveoli
Difference between breathing and respiration
Respiration is the chemical process
Atrium is located in ______
Upper 2 chambers
Ventricles are located in ____
Lower 2 chambers
3 blood vessels
Arteries, Capillaries, and Veins
Structures that seprate the chambers of the heart
Septum and Valves
What is the Aorta? Vein Cava?
Aorta is the largest artery. Vein Cava is the largest vein.
Difference between arteries and veins
Arteries carry blood away while veins carry blood to the heart
Way the food enters and passes through
Mouth -> Esophagus -> Stomach -> Small intestines -> Large Intestine -> Rectum -> Anus
3 main functions of the Digestive System
Digestion, Absorption, and Excretion
involuntary waves of muscle contraction that keep food moving along in one direction through the digestive system
Small fingerlike projections on the walls of the small intestines that increase surface area
4 organs found in excretory system
Kidney, Ureter, Bladder, Urethra
organ that removes urea, excess water, and other waste products from the blood and passes them to the ureter
tube that carries urine from the kidney to the urinary bladder
Stores urine until elimination
tube that carries urine from the bladder and releases it from the body; in males, tube through which semen is released from the body
tiny filtering unit of the kidney
4 OTHER Excretory Organs
Rectum, liver, skin, and lungs
Function of the Endocrine System
help regulate and coordinate body systems
chemical "messengers" of the endocrine system that are released into the blood
5 major glands
Pituitary, Parathyroid, Thyroid, Thymus, Adrenal
