What is the primary function of the integumentary system?
To protect the body from the outside environment.
What two types of skeletal muscles are there?
Flexor, extensor
What is the primary function of the skeletal system?
What is another name for the circulatory system?
Cardiovascular system
What is tissue?
A collection of cells working together
How does skin help the body maintain homeostasis?
Goosebumps, sweat, veins expanding and contracting, etc...
What tissue attaches muscle to bone?
Tendon
Which part of the bone is responsible for creating new blood cells?
Bone Marrow
Where are capillaries located in the lungs? What is their function?
Located in the alveoli, function is to assist in gas exchange of oxygen and carbon dioxide
What is the largest organ in the human body?
Skin
Name the three layers of skin.
Epidermis, dermis, subcutaneous fat
What are the three types of muscle in the body?
Skeletal, Cardiac, Smooth
Name at least two types of joints and give an example of them.
(Ex: Hinge/elbow, gliding/wrist, ball-and-socket/shoulder)
What is pulmonary circulation? How is it different from systemic circulation?
Pulmonary circulation is where blood leaves the heart, is sent to the lungs to be oxygenated, and is taken back to the heart. This is different from the systemic circulation because this is the only part of the circulatory system where arteries carry oxygenated blood and veins carry oxygenated blood.
What level of organization do individual muscles fall under?
Organ
How does skin also help the excretory system, which is responsible for removing waste from the body?
Sweat glands/Sweating
What kind of muscle is the lining of your stomach made of?
Smooth
What is the name of the tissue that connects bones to each other?
Ligament
What are capillaries responsible for in systemic circulation?
Transferring oxygen and nutrients to cells and collecting waste from cells
Ex: Cardiac Muscle Cell, Cardiac Muscle Tissue, Heart, Cardiovascular System, Human
How much does the skin of an average adult weigh?
8lbs
Which two types of muscle are described as "striated"
Skeletal and Cardiac
What is the primary function of flat bones? Give an example.
To protect major organs; skull, pelvis, rib cage
Describe, step by step, the journey of oxygen through the body and carbon dioxide out of the body.
Air is inhaled through the nose, filtered in the trachea, and distributed through the lungs by bronchioles. It is then sent to the alveoli where capillaries release carbon dioxide from blood cells and pick up oxygen. Oxygenated blood is sent back to the heart through the pulmonary veins and pumped into the aorta to be sent to capillaries throughout the body. In these capillaries it is exchanged with cells and carbon dioxide is picked up. Carbon dioxide is taken back to the heart through veins and the vena cava. It is then pumped up through the pulmonary artery to the capillaries in the alveoli where it is exchanged for more oxygen and exhaled from the body.
