Organization Of The Body: Chapter Two Flashcards
Cells grouped together are called
Tissues
Ex: groups of muscle cells are muscle tissues
All parts of the body are composed of individual units called
Cells
Muscle, nerve, epithelial (skin, and lining of internal organs and cavaties), and bone are examples of
Cells
Collections of different tissues working together are
Organs
Groups of organs working together are called the
Systems of the body
How many systems are there in the body?
10/11 Systems
The system that transports blood through the body and includes: heart, blood, blood vessels such as arteries, veins, and capillaries is called the
Circulatory System
The system that transports lymph, which contains Lymphocytes that fight against disease and include lymph vessels and lymph nodes is called the
Lymphatic System
The system that brings food into the body and breaks it down so that it can enter the bloodstream and includes the mouth, stomach, and intestines is called the
Digestive System
The system that is composed of glands that send messages called hormones into the blood and includes thyroid, adrenal, and pituitary glands is called the
Endocrine System
The system that produces the cells that join to from the embryo is called the
Female and Male Reproductive Systems
female: eggs, ovaries, uterus
male: testes, sperm
The system that supports the body and allows it to move is called the
Includes: muscles, bones, joints, and connective tissue such as cartilage.
Musculoskeletal System
The system that carries electrical messages to and from the brain and spinal cord is called the
Nervous System
The system that controls breathing and includes the trachea, bronchial tubes, and lungs is called the
Respiratory System
The system that receivers messages from the environment and sends them to the brain and includes the skin, eyes, and ears is called the
Skin and Sense Organ Systems (Integumentary)
The system that produces urine and sends it out of the body through the kidneys, ureters, bladder, ad urethra is called the
Urinary System
What is a body cavity?
A space that contains organs
The cavity that is located in the head and surrounded by the skull and contains the brain is called the
Cranial Cavity
The cavity that is also known as the chest cavity that is surrounded by the breastbone and ribs is called the
Includes: lungs, heart, windpipe, and bronchial tubes.
Thoracic Cavity
The root word CRANI- means
Skull
The root word THORAC- means
Chest
The lungs are each surrounded by a double membrane known as the
Pleura
The space between the pleura membranes is the
Pleural cavity
The large area between the lungs that contain the heart, esophagus, trachea, and bronchial tubes is called the
Mediastinum
The space below the thoracic cavity is called the
Includes: stomach, liver, gallbladder, and small and large intestines.
Abdominal Cavity
What is the muscle that separates the abdominal and thoracic cavities?
The diaphragm
The organs in the abdomen are covered by a double membrane called the
Peritoneum
What does the peritoneum do?
Attaches the abdominal organs to the abdominal muscles and surrounds each organ to hold it in place
What area/cavity are the kidneys located?
The Retroperitoneal area/cavity
Where is the pelvic cavity?
Below the abdominal cavity
What is the pelvic cavity surrounded by?
The pelvis (bones of the hip)
The spinal columns are the
Backbones
The nervous tissue within the spinal cavity is the
Spinal cord
What enters and leaves the spinal cord and carries messages to and from all parts of the body?
Nerves
A long row of bones from the neck to the tailbone is the
Spinal column
Each bone in the spinal column is called a
Vertebra (backbone)
Two or more: Vertebrae
A piece of connective tissue that lies between each backbone is called a
Disk (or disc)
A Disk (disc) is composed of
Cartilage
How many divisions of the back are there?
5
How many bones make up the Cervical (neck) region?
7 bones
Abbreviation C1-C7
How many bones make up the Thoracic (chest) region?
12 bones
Abbreviation T1-T12
How many bones make up the Lumbar (loin and waist) region?
5 bones
Abbreviation L1-L5
How many bones make up the Sacral (sacrum and lower back) region?
5 fused bones
Abbreviation S1-S5
