Study Notes

Structural Organization of the Body and the First Responder

The structural organization of the body (specifically the types of body tissues) is a key objective for first responders.
Body tissues are composed of cells grouped by size, shape, and function,
Four types of tissue: Epithelial, Connective, Muscle, and Nervous

Epithelial Tissue

Covers the outside of the body (e.g., skin) and lines the inside of the body.
Its membranes are two thin layers of tissue that adhere together.
Some cells in epithelial tissue secrete fluids.

Connective Tissue

Supports and connects organs and tissues.
Adipose tissue stores fat cells.
Cartilage provides firm, flexible support.
Tendons connect skeletal muscle to bone.
Ligaments connect bones at joints.

Muscle Tissue

Contracts and moves body parts.
Cardiac muscle is striated and involuntary, contracting the heart.
Skeletal muscle is striated and voluntary, attached to the skeleton.
Smooth muscle is non-striated and involuntary, facilitating movement in various body systems.

Nervous Tissue

Reacts to stimulation and conducts impulses,
A key part of the nervous system.

Organ Systems

The body is made up of organ systems, each with specific functions.
Skeletal: Provides support, protection, and movement. Components such as skull, ribs, pelvis, humerus and femur are notable parts of the skeletal system.
Muscular: Provides support, protection, movement, and generates heat. Examples such as Diaphragm, Pectoralis Major and Gluteus Maximus are included.
Circulatory: Pumps blood and transports oxygen. Key components are blood, arteries, veins and the heart.
Lymphatic: Stimulates the immune response and produces lymphocytes. Components of note are the Spleen, Tonsils and the Thymus Gland.
Respiratory: Allows exchange of oxygen and carbon dioxide. Parts include the Lungs, Diaphragm, Alveoli and the Pharynx.
Digestive: Digests food and absorbs nutrients. Includes the Esophagus, Stomach, Liver, Small Intestine and Large Intestine.
Integumentary: Protects, regulates body temperature, and provides sensation. Includes skin, hair, and sweat glands.
Nervous: Processes information. Includes the Brain and Spinal Cord.
Sensory: Provides sensation. Includes eyes, ears, nose, mouth, and skin.
Urinary: Eliminates urine. Includes kidneys and bladder.
Endocrine: Controls bodily functions. Includes the Pancreas and Thyroid gland among other glands.
Reproductive: Controls reproductive processes. Includes the Uterus, Ovaries, Vagina, and Testes for example.
