Essential Questions How is the human body organized? What are the structural components of the body? How does the body’s structural organization relate to its support and movement? Remember structural organization

Composed of: Remember structural organization

Epithelial tissue-protects by covering internal and external surfaces and produces secretions. Connective tissue-supports/connects organs & tissues. Muscle tissue-cells have ability to contract/move body. Nervous tissue-cells react to stimuli/conduct impulses Remember structural organization

Squamous Cuboidal Columnar Remember structural organization

Can be found in organs and in glands: In small intestines ET can absorb nutrients In glands ET can secrete hormones & enzymes In skin ET can excrete sweat. (All glands are made of epithelial tissue.) Remember structural organization

formed by putting two thin layers of tissue together, cells may secrete a fluid Membranes are vital because they separate the cell from the outside world. They also separate compartments inside the cell to protect important processes and events. Membranes are Epithelial or Connective

1. MUCOUS MEMBRANES– lines digestive, respiratory, reproductive and urinary systems – produces mucous to lubricate and protect the lining They line various body cavities that are exposed to the external environment and internal organs. 2. Serous Membranes– double-walled membranes produces a watery fluid (Serous fluid) lines closed body cavities Pleural, Pericardial, Peritoneal the outer part of the membrane that lines the cavity is the PARIETAL membrane the part that covers the organs is the VISCERAL membrane.

PLEURAL MEMBRANE – lines thoracic or chest cavity and protects the lungs PERICARDIAL MEMBRANE – lines the heart cavity and protects the heart PERITONEAL MEMBRANE – lines the abdominal cavity and protects abdominal organs The watery/serous fluid produced allows organs to move freely and prevents friction

Are made of two layers of connective tissue. Synovial membrane- Lines the joint cavity and produces synovial fluid which prevents friction with movement of the bones.

Connective tissue supports and connects organs and tissue Adipose type of connective tissue that stores fat cells. Cartilage firm, flexible support of the embryonic skeleton and part of the adult skeleton. Tendons white bands of connective tissue attaching skeletal muscle to bone. Ligaments strong, flexible bands of connective tissue that hold bones firmly together at the joints. Blood/Lymph liquid blood tissue and lymph tissue. Bone hardened bone tissue that supports and protects body Remember structural organization

Connective tissue Adipose FibrocartilageElastic cartilage Remember structural organization

Repair of damaged tissue occurs continually. Two types Primary takes place in clean wound where infection is not present. Secondary larger and deeper wounds. Takes place by granulation. Cicatrix –Scar tissue

Muscle tissue contracts and moves a body part  Cardiac  striated, involuntary  contracts the heart  Skeletal  striated, voluntary  attached to the skeleton  Smooth nonstriated, involuntary provides movement in various body systems Remember structural organization

Muscle tissue Cardiac Skeletal Smooth Remember structural organization

– cells that react to stimuli and conduct an impulse Neurons are highly specialized cells that generate and transmit electrical impulses (action potentials) permitting rapid communication between distant areas of the body.

Smooth Cardiac Skeletal Muscle- pink Hard – Cartilage, Bones Soft – Adipose, Ligaments, Tendons Connective- blue Skin Membranes – Mucous and Serous Epithelial- green Neuron Nerve- yellow
