Body Regions

Anatomical position is when the body erect,feet slightly apart,palms facing forward,and thumbs point away from the body.

Superior(cranial)is toward the head end or upper part of the body.

Inferior(caudal) is away from the head or lower part of the body.

Anterior(ventral) is toward or at the front of the body and posterior(dorsal) is toward or T the midline of the body.

Lateral is away from the midline of the body and intermediate is between a more medial and a more lateral structure.

Proximal is closer to the origin of the body and distal is farther from the origin of a body part.

Superficial(external) is toward or at the body surface and deep(internal) is away from the body surface.

Body planes are sagittal,midsagittal,frontal,transverse,and oblique section.

Body cavities are dorsal caviy,ventral cavity,thoracic cavity,abdominal cavity,and pelvic cavity.

Temperature Change

Homeostasis

Homeostasis is the tendency of an organism or cell to regulate it's internal conditions, usually by a system of feedback controls, so as to stabilize health and functioning,regardless of the outside changing conditions.The liver,kidneys,and the brain help maintain homeostasis. The liver is in charge of metabolizing toxic things and maintaining carbohydrate metabolism.kidneys are in charge of regulating blood,maintenance of salt and ion levels in blood. Heat is mainly produced by the liver and muscle contractions. High temperatures can be stressful to some body's. Energy intake is internal heat produced plus external work plus steerage. Blood glucose is regulated with two hormones insulin and glucagon which is released from the pancreas. When blood sugar levels get too high, insulin is also released from the pancreas. Sugar is steered in the body as glucagon. When blood calcium gets too low, calcium sensing receptors in the parathyroid gland begin to work. It increases blood calcium and releases from bones. Decreasing calcium levels in the blood causes more calcium to be fixed in the bones. Positive feedback is how the body works really fast when your hot or cold like when your hot you sweat and when your cold you shiver. Negative feedback is how much pressure is on your body especially with temperature change.
