Physiology
What are the nine levels of organization in the human body?
- atoms
- molecules
- macromolecules
- organelles
- cells
- tissues
- organs
- organ systems
- organism
Various terms are used to describe the location of body organs when the body is in the anatomical position. What is the anatomical position?
Standing erect with, face forward, arms at the sides, and palms and toes directed forward.
Anterior / Posterior
Anterior meaning the front of the body
Posterior meaning back of the body
Superior / Inferior
Superior meaning towards the head
Inferior meaning away from the head
Medial / Lateral
Medial meaning towards the middle of the body
Lateral meaning towards the outside or far from the middle of the body.
Proximal / Distal
Proximal meaning closer to the midline
Distal meaning Further from the middle
Superficial / Deep
Superficial meaning closer to the outside
Deep closer to the interior
Central / Peripheral
Central meaning the center of the organ or organism
Peripheral meaning at the edge of the organ or organisim
Contralateral / Ipsilateral
Contralateral meaning structures located on opposite sides of the body
Ipsilateral meaning structures located on the same side of the body.
The body can be divided into ______________ and ___________________ portions, each of which can be further subdivided into specific regions
The axial and appendicular regions
The body or its parts can be sectioned along certain planes. A ________________ or ______________ (vertical) cut divides the body into equal right and left portions
Median or Midsagittal
A ________________________ or ________________ section is a saggittal section parallel to the midline.
Parasagittal or paramedian
A frontal (_______________) cut divides the body into anterior an posterior parts
Coronal
A ______________(horizontal) cut is a cross section.
Transverse
The human body has two major cavities: The ___________________ and the ____________________.
The Posterior (dorsal) Body Cavity and Anterior (ventral) Body Cavity
Each of the two main body cavities the: the anterior and the posterior cavities is subdivided into smaller cavities, within which specific ___________________ are located.
Viscera
Specific _______________ _________________ line body cavities and adhere to the organs within these cavities
Serous Membranes
The human body has four ______________ _____________.
Organ Systems
The eleven organ systems in the human body are:
- Integumentary (skin)
- Skeletal
- Muscular
- Nervous / Sensory
- Endocrine
- Blood / Cardiovascular
- Lymphatic
- Respiratory
- Digestive
- Urinary
- Reproductive
Support, movement and protection. The __________________ system, which includes the skin, protects the body
Integumentary
The __________________ system contains the bones
Skeletal
The _________________ system contains three types of muscles: smooth, skeletal, and cardiac
Muscular
The primary function of _____________system and _____________ system is support and movement.
Skeletal and Muscular
The __________________ contains the brain, the spinal cord, and nerves. Because the _____________________ communicates with both the sense organs and the muscles, it allows us to respond to outside stimuli.
The Nervous System
The __________________ consist of the hormonal glands.
The Endocrine System
The ________________________ and the _________________ coordinate and regulate the activities of the body’s other systems.
The Nervous and Endocrine Systems
What five systems help to maintain the body
- Cardiovascular System
- Lymphatic System
- Respiratory System
- Digestive System
- Urinary System
What organs are included in the Cardiovascular System?
The heart and vessels
What organs are included in the Lymphatic System?
Lymphatic Vessels, nodes, spleen and thymus
What organs are included in the Respiratory System?
Lungs and conducting tubes
What organs are included in the Digestive System?
Mouth, Esophagus, Stomach, Small and Large Intestines and associated Organs
What organs are included in the Urinary System?
The Kidneys and Bladder
What are the reproductive organs in the male species.
Testes, other glands and ducts, and penis
What are the reproductive organs in the female speceies
Ovaries, uterine tubes, vagina and external genitalia.
____________________ is the relative constancy of the body’s internal environment, which is composed of blood and tissue fluid that bathes the cells.
Homeostasis
_____________________mechanisms help maintain homeostasis. _____________________ occurs in processes with a definite cutoff point.
negative feedback
Positive feedback
All of the body’s organs systems contribute to _________________. Some, including the respiratory, digestive, and urinary systems, remove and or add substances to the blood.
Homeostasis
The Nervous and endocrine systems regulate the activities of other systems. __________________ is a self-regulatory mechanism by which systems and conditions of the body are controlled.
Negative feedback.
The chin is __________________ to the navel
The chin is SUPERIOR to the navel.
