Levels of Organization & Characteristics of Life
All 11 body systems working together make up this level.
What is the organismal level?
This directional term describes the position of the antebrachium compared to the brachium
What is distal?
The brain is protected by this cavity
what is the cranial cavity?
The spleen is found in this abdominopelvic region.
What is the left hypochondriac region?
Blood clotting and childbirth are classic examples of this.
What is positive feedback?
Breaking down proteins into amino acids is an example of this metabolic process
What is catabolism?
This system eliminates nitrogenous waste from the blood.
What is the urinary system?
The heart is located in this subdivision of the thoracic cavity.
What is the pericardial cavity?
The navel is located in this abdominopelvic region.
What is the umbilical region?
In terms of input and output, this type of feedback occurs when the output goes in the opposite direction of the input.
What is negative feedback?
When the nervous system senses heat and signals sweat glands to cool the body, this characteristic of life is demonstrated
What is responsiveness?
The spleen, lymph nodes, and tonsils are part of this system.
What is the lymphatic (immune) system?
The parietal pleura lines the chest wall, while the visceral pleura directly covers this organ
What is the lung?
This abdominopelvic region contains the urinary bladder
what is the Hypogastric region?
In a control loop, sweat glands that lower body temperature serve in this role.
What is the effector?
The brain and heart are examples of this level.
what are organs?
TTo examine the gallbladder, a surgeon chooses a cut that divides the body into unequal right and left portions.
What is a parasagittal plane?
Organs such as the kidneys and pancreas lie posterior to the peritoneal cavity and are described by this term.
What is retroperitoneal?
This abdominopelvic region is a common site for appendiceal pain
What is the right inguinal (iliac) region?
This technique is most often used in obstetrics because it uses sound waves instead of radiation.
What is ultrasound (sonography)?
The skin maintains this characteristic of life by keeping the body’s internal environment distinct from the external environment.
What is maintaining boundaries?
Pain on the sole of the foot would be described as occurring in this region.
What is the plantar region?
This serous membrane covers the surface of the heart
What is the visceral pericardium ?
Pain located lateral to the umbilical region on the left side often localizes to this region containing the descending colon.
What is the left lumbar region?
To avoid overlap of structures, a rotating X-ray tube produces cross-sectional “slices”—a method especially useful for brain and abdominal soft tissues.
What is computed tomography (CT)?
