Module 2 Flashcards
homeostasis
A state of equilibrium that is maintained in the bodies, internal environment to support and sustain life.
what are two examples of homeostasis?
The body’s production of insulin and the adjustment of body temperature.
What is anatomical terminology?
Terms that are used to describe the human body.
What do anatomical terms describe?
Specific locations, positions or directions of the human body
What are three examples of anatomical terms?
Anterior posterior superior
What is the terminology breakdown and definition of anatomy?
Ana- apart
Tome- to cut
What are cells?
The basic building blocks of the human body there are several different cells in the human body, and each has a specific purpose.
What are the eight organizational levels of the human body in order?
Atom, molecule, organelle, cell, tissue, organ, organ system, and organism
What are three examples of atoms?
Carbon, hydrogen and oxygen
What are three examples of molecules?
Sugars, proteins, and water
What are three examples of organelles?
Mitochondria nucleus and ribosomes
What are three types of cells?
Epithelial cell, nerve cell and muscle cell
What are four examples of tissues?
Epithelial tissue, nervous tissue, muscle tissue and connective tissue
What are three examples of organs?
Lungs brain stomach
What are four examples of organ systems?
Respiratory system, nervous system digestive system, and circulatory system
What are three examples of organisms
Human organism, elephant organism , lion organism
What is the definition of tissue?
A grouping of similar cells that work together to perform a specialized function.
What are the four types of tissue found in the human body?
Epithelial, connective, muscle and nervous tissues
What are epithelial tissue?
Forms the outer surfaces of the body and line the body cavities as well has the tubes that leads to the exterior of the body .
what are six of the functions of epithelial tissue?
Protection, sensation, secretion, absorption ,excretion, and diffusion
How does epithelial tissue perform protection?
Protects the outer skin by forming a physical barrier over underlying tissue
How does epithelial tissue function sensation?
Forms specialized cells in the skin, eyes, ears, nose, and tongue to help the body interprets sensory stimuli
How does epithelial cells function in secretion?
Secretes substances, such as hormones, enzymes, and lubricating fluid via various glands
How does epithelial cells function absorption?
Lines the small intestine and aid the body in absorbing nutrients from food
How to epithelial cells function in excretion?
Excrete waste products in the kidneys and sweat from the skin
How do epithelial cells function in diffusion?
Found in the lungs and capillaries where diffusion of gases liquids and nutrients occur
What is connective tissue?
Builds the support for the bodies organs and muscles sheaths and also connects muscles to bones and bones to joints. It is the most abundant tissue in the body.
What is the function of muscle tissue?
Forms the muscles throughout the body
What are the three types of muscle tissue?
Skeletal muscle, smooth muscle and cardiac muscle
What is the function of the skeletal muscle?
Voluntarily controlled and is used by the body for movement and posture
What is smooth muscle?
Involuntary muscle and is found in organs such as the esophagus, stomach intestine and bladder. It is not under conscious control, and is controlled by the autonomic nervous system.
What is cardiac muscle?
Found in the heart and is involuntary and controlled by the autonomic nervous system
What is the function of nervous tissue?
Functions to communicate throughout the body. Nerve cells are excitable and can conduct electricity. nervous tissue coordinates and controls the functions of the body.
What are organs?
Structures in the body that perform specific purposes.
What are body systems?
Group of different organs functioning together for a common purpose.
Function of the Integumentary System?
Protective membrane, temperature, regulator, and sensory receptor
Function of skeletal system
- framework and movement
-Shape, support, protect and storage place for minerals. Makes movement possible
Function of the muscular system?
-Framework and movement
- produce movement, maintain posture and produce heat
Function of the nervous system?
-Communication and control
-transmits impulses, respond to change , responsible for communication and exercises control over all parts of the body.
Function of the endocrine system?
-communication and control
- glands produce hormones, chemical messengers, that provide communication and control throughout the body
Function of the cardiovascular system?
-Transportation and immunity
-transport oxygen and carbon dioxide, delivers nutrients and hormones and removes waste products.
Function of the blood and lymphatic system?
-Transportation and immunity
-transport oxygen and carbon dioxide, chemical substances and cells that act to protect the body from foreign substances. Stimulates immune response, protects the body, and transports proteins and fluids
Function of Respiratory system?
-Distribution and elimination
-furnishes oxygen for use by individual tissue cells and removes their gaseous waste products, carbon dioxide.
Function of digestive system?
-distribution and elimination
-digestion, absorption, and elimination
Function of the urinary system?
-distribution and elimination
-produces urine, transport and eliminates urine
The kidneys help maintain electrolyte, water, and acid-base balance in the body.
Function of Reproductive system?
-Cycle of life
-responsible for sexual characteristics of a male and/or female. Proper functioning insured survival of the human race
What are the characteristics of anatomical position?
- body standing upright
- head facing forward
- arms extended by side of body
- the palms facing frontward
Left and right view?
Left and right are based on the subject’s point of view rather than from the Point of view of the observer.
What is a body plane?
Imaginary sections used to describe the location of body part and study the human body
What are the 4 types of body planes?
Sagittal,
midsagittal,
transverse/horizontal,
frontal/coronal
Describe the sagittal plane
Divides the body or structure vertically into left and right sections
Describe the midsagittal plane
Divides body or structure into equal left and right halves at the midline
Describe the transverse/horizontal plane
Divides the body or structure into superior and inferior sections
