What is the primary purpose of negative feedback?
Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

In which body cavity are the lungs located?
How many cavities are in the body?
Humans have four body cavities: (1) the dorsal body cavity that encloses the brain and spinal cord; (2) the thoracic cavity that encloses the heart and lungs; (3) the abdominal cavity that encloses most of the digestive organs and kidneys; and (4) the pelvic cavity that encloses the bladder and reproductive organs.
Where is the pelvic cavity located?
The pelvic cavity is a bowl-like structure that sits below the abdominal cavity. The true pelvis, or lesser pelvis, lies below the pelvic brim (Figure 1). This landmark begins at the level of the sacral promontory posteriorly and the pubic symphysis anteriorly.
What are the 3 ventral cavities?
Ventral body cavity–the thoracic cavity, the abdominal cavity, and the pelvic cavity in combination. Thoracic cavity–the space occupied by the ventral internal organs superior to the diaphragm. Abdominopelvic cavity–the abdominal cavity and the pelvic cavity in combination.
Is the heart in the ventral cavity?
The ventral cavity is at the anterior (or front) of the trunk. Organs contained within this body cavity include the lungs, heart, stomach, intestines, and reproductive organs. The abdominopelvic cavity fills the lower half of the trunk and is subdivided into the abdominal cavity and the pelvic cavity.
