The Human Body
Organs
The heart pumps blood through the blood vessels of the circulatory system.
The human brain is the central organ of the human nervous system.
The human lungs are a pair of large, spongy organs optimized for gas exchange between our blood and the air.
Organ Systems
An organ system is a group of multiple organs that work together to perform one or more functions.
Homeostasis - maintaining a stable internal environment and temperature
The cardiovascular, respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, which allows more blood to flow near the skin's surface. The skin may also produce sweat if the body gets too hot. When the sweat evaporates, it helps to cool the body. Rapid breathing through the lungs can also help the body eliminate excess heat.
Cells
the smallest structural and functional unit of an organism
Cell Specialization - different types of cells differ in size and shape, and do different things
Cell Differentiation - non-specialized cells become specialized
Stem Cell - undifferentiated cell that is capable of giving rise to certain other kinds of cells through differentiation
Tissue
any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products
Muscle
Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract
Epithial
Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body
Connective
Tissue that connects, supports, binds, or separates other tissues or organs, typically having relatively few cells embedded in an amorphous matrix, often with collagen or other fibers, and including cartilaginous, fatty, and elastic tissues.
Nervous
Nervous tissue is the main tissue component of the two parts of the nervous system; the brain and spinal cord
