Exam 11 human body Flashcards
(made by student)
what is anatomy
the study of the different organs and structures within the body
what is physiology
the study of the organs and the functions of the in the human body
what is a groupof cells similar in structure and function
tissue
where is epithelial tissue used
Protection(skin) absortion(lining of your small intestine) secretion(glands)
what is conective tissue
Most abundant and diverse. Support, bind together, and
protect other tissues or organs. Composed of protein fibers (collagen,
elastin). Bone, cartilage, tendons, ligaments, adipose (fat) tissue, and blood.
ihow does muscle tissue work
Contracts and causes movement.
what are the three types of muscle tissue
Skeletal
muscle (attached to bones and allows for voluntary
movement), cardiac muscle (found only in the heart,
pumps blood involuntarily), and smooth muscle (found in
the walls of internal organs, like the intestines and blood
vessels, controlling involuntary movements)
what is the type of tissue found int he brain?
nervous
what is the skin system called
integementry system
how does protection work in the skin
physical barrier against mechanical impacts, pathogens,
and harmful substances. Minimizes water loss and protects against
UV radiation (thanks to melanin protein) that damage cell DNA
what is sensation
a sensory organ in your skin rich with nervous tissue
Thermoregulation:
Through the dilation and constriction of blood
vessels and the activity of sweat glands, the skin helps regulate body
temperature (homeostasis) in response to environmental changes
what is the way sweat works
through excreation
why is vitamain D important
this helps calcium be absorbed, healthy bones, immunity, and so much more!
what are the 3 layers of skin fro inside to out
epidermis, dermis, and hypodermis
what layer of skins vitamin d found in
epidermis
what layer of skin are the wax glands found in
dermis
where is melanin found
epidermis
what mostly makes up the hypo dermis
fat and connective tissue
