Module 16 Study Guide Modules 1-5
1. What is homeostasis? Maintain body temperature
2. Describe the functions of the skeletal system. Responsible for giving us our
shape and support. Serves as an attachment, and helps protects some organs.
3. The ax

SENSATION AND PERCEPTION
1. Sensation/Perception- Sensation is the process by which our sensory receptors and nervous system
receive and represent stimulus energies from our environment. Perception is the process of organizing
and interpreting sensory inf
Cardiovascular/Circulatory System Differentiated Instruction Menu Chapters 14-16
Educational research proves that students learn in different ways. With this in mind, you will have an opportunity to
select from various learning activities that best suit Y
The Cardiovascular System
The Cardiovascular System
A closed system of the heart and blood vessels
The heart pumps blood
Blood vessels allow blood to circulate to all parts of the body
The function of the cardiovascular system is to deliver oxygen and
The only fluid tissue in the human body
Classified as a connective tissue
Components of blood
If blood is centrifuged
Erythrocytes sink to the bottom (45% of blood, a percentage known
THE CARDIOVASCULAR SYSTEM
Function of the system as a whole.
What does the CV System consist of ?
1. Pump (Heart) 2. Distribution vehicle (blood)
3. Distribution conduits (blood vessels)
What is the Purpose of the CV System?
THE CARDIAC CYCLE SYSTOLE AND DIASTOLE
MINDSET The heart is a mechanical pump. This is an advantage in studying the heart because its function is easily accessible and intuitive. We can see it! Valves open and close; walls contract and r
Control of the Heart
Excitation-Contraction (E-C) Coupling
In order to meet the metabolic needs of the body the heart must be controlled. This involves initiation of the contraction which implies heart rate. Also in order to increase cardiac output the he
THE FETAL CIRCULATION IS A SPECIAL CIRCULATION BECAUSE:
1. The fetus gets its oxygen and nutrients from the mother. Therefore the lungs and G.I. Tract are nonfunctional during gestation. 2. The PLACENTA serves as an interface between the
Arterial Blood Pressure Cardiac Output
Function - Arterial vessels distribute blood to capillar y beds. The arterial pressure (i.e., gradient) is the direct determinant of ow through the capillaries. About 10% of the blood is in the ar
Excitation - Contraction Coupling
Control of Muscle Contraction
We now know HOW muscles shorten. BUT there is something important still to know. What is it? Hint - Is muscle shortening all the time? Answer - We have to control it. i.e., We have to start i
MECHANICAL PROPERTIES OF WHOLE SKELETAL MUSCLE CELLS
Mechanical Characteristics of a Whole Muscle
3 major mechanical variables:
The force put on an object by a contracting muscle is muscle TENS
ELECTROPHYSIOLOGY OF THE CELL
Membrane potential (Em) Measurement of a potential difference (voltage) across the cell membrane using a micropipette and volt meter. Every cell has a membrane potential. Certain cells like muscle and nerve are electrically s
Example of a perfectly formed human being with regard to musculature! :-)
Muscle Function Denition An organ whose function is mediating motion. How does muscle provide motion? Muscle has the ability to shorten. (Cannot lengthen)
MOVEMENT OF MOLECULES ACROSS CELL MEMBRANES
The plasma membrane is a barrier to insulate and compartmentalize the interior of the cell from the outside environment. However, some molecules must pass over the membrane and a
Cell to Cell Signaling.
Cell to Cell Communication
In a multi-cellular organism it is necessary for cells to communicate to integrate their activities. Eg. - The heart has to beat faster because the muscles need more blood and oxygen. The liver
The Plasma Membrane
The Plasma Membrane
History - When life was evolving and macromolecules were moiling and seething in a primeval slime, it was necessary to isolate these molecules from the environment. Membranes evolved to s
I. Macromolecules A. Macromolecules are a defining feature of living sytems. Macromolecules such as proteins, nucleic acids and polysaccharides are made from the smaller subunits amino acids, nucleotides and simple sugars but the macromolec
INTRODUCTION TO PHYSIOLOGY
The study of the COMPONENTS making up the living sytem. These components range from something large like a heart or kidney to cells to molecules making up the cells.
