A cell is the basic unit of structure and function of living things. Multicellular organisms are made up of many different
types of cells and tend to be specialized. These specialized cells are all different and specialized to perform a specific
function. For example, pancreatic cells produce insulin.
Your blood is made up of many different types of cells. Plasma is a straw colored fluid in which the blood cells “float”
and travel in. The Red Blood Cells are a specialized type of cell that helps to transport nutrients and wastes throughout
your body. White Blood Cells are specialized to help fight infections and foreign invaders. Platelets are plasma proteins
that form a seal, a scab, around wounds to slow bleeding and begin the healing process. These cells travel through the
circulatory system, which acts as your body’s transportation system, like roads in a city.
The components of blood are made up of
1. A liquid plasma
2. Red Bloods Cells and carry nutrients (food and
oxygen) and wastes (carbon dioxide)
3. White Blood Cells that fight foreign invaders
4. Platelets that helps the clotting process

Muscle cells are specialized types of cell that helps to generate force to produce a type of movement. Muscle tissue are
found everywhere in your body, both under the skin and deep within the body. They are responsible for both voluntary
and involuntary motion. There are three types of muscle tissue.
Skeletal Muscle are
1. Attached to bones
2. Under the microscope, have alternating light and dark bands,
known as striations
3. Large, have many nuclei, long and slender shaped
4. Mostly controlled directly by the central nervous system
Examples: Muscle Fibers in leg
Movement: Voluntary movement – like typing
Smooth Muscle are
1. Usually NOT under voluntary control
2. Spindle shaped with one nucleus and not striated
3. Found in hollow structures
4. Can move without nervous stimulation (not under direct control of
central nervous system
Examples: Stomach, Intestines,
Movement: Involuntary movement -- control direction of blood in Blood
Vessels,
Cardiac Muscle are
1. A mixture of Smooth and Skeletal Muscle
2. Smaller striations than Skeletal Muscle
3. Under involuntary control like Smooth Muscle
4. Only found in the heart
Examples: Heart
Movement: Involuntary movement – pumping blood

transmits information to the nervous system as well as a barrio against the outside environment. The skin is made up
of two layers – the epidermis and the dermis.

The largest organ or component in the integumentary system is your skin; it contains sensory receptors which
transmits information to the nervous system as well as a barrio against the outside environment. The skin is made up
of two layers – the epidermis and the dermis.
The epidermis is the outer layer of the skin which is divided into an outer layer of dead cells and an inner layer of living
cells. The inner layer of living cells divide rapidly and move up towards the outside of the skin, pushing the older cells to
the surface (outside). The outer layer of the skin is tough, flexible, and waterproof which is shed or washed away every
4-5 weeks. There are no blood vessels in the epidermis (which is why you don’t always bleed when you scratch
yourself).The epidermis also contains melanin, a dark brown pigment that helps protect the skin from sun damage by
absorbing the UV rays from the sun.
The inner layer is the dermis, which has blood vessels, glands, nerve endings, sensory receptors, smooth muscle, and
hair follicles. This portion of the skin interacts with other body systems to help maintain homeostasis (an internal
balance). In this layer, you also have sweat glands and sebaceous glands. Sweat glands produce sweat to help maintain
body temperature. Sweat also helps regulate water, salt, and other compounds in the body. Sebaceous glands produce
an oily secretion called sebum. Sebum spreads around the surface of the skin, creating a flexible and waterproof
exterior.
