organization of your body

• The levels of organization in the human body include: cells, tissues, organs, and organ systems.

• A tissue is a group of cells that work together.

• An organ is made of two or more tissues that work together.

• Organs that work together make up organ systems.

• There are four tissue types in the body: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

• There are 12 major organ systems in the body.

• Organs and organ systems work together to maintain homeostasis.

the Integumentary system

• Skin acts as a barrier that keeps particles and water out of the body.

• The skin helps to cool the body in hot temperatures, and keep the body warm in cool temperatures.

• Skin is made up of two layers, the epidermis and the dermis.

• Pimples occur when the skin produces too much sebum.

• Hair and nails are made of keratin, the same protein as skin.

• Nails grow from nail beds and hairs grow from hair follicles in the skin.

• Skin cancer can be caused by excess exposure to ultraviolet light from the sun or tanning beds.

• Frequent bathing helps keep the skin clean and healthy.

the skeletal system

the skeletal system

• Bones, cartilage, and ligaments make up the skeletal system.

• The skeleton supports the body against the pull of gravity.

• The skeleton provides a framework that supports and protects the soft organs of the body.

• Bones work together with muscles to move the body.

• Blood cells are mostly made inside the bone marrow.

• There are three types of joints in the body: fixed, partly movable, and movable.

• Calcium and vitamin D are two of the most important nutrients for a healthy skeletal system.

• The break down of the cartilage leads to pain and stiffness in the joint.

• A sprain is an injury to a ligament.

• A fracture is a break or crack in a bone.
