1 Unit C: Body Systems Specific Objectives:
Analyze the relationship of tissues, organs, and body systems. Explain the structural units of the body. Analyze body tissues and membranes.

2 Body Systems ANATOMY – study of the parts of the body
PHYSIOLOGY – function of the body GROSS- LARGE MICROSCOPIC- small CYTOLOGY- cell HISTOLOGY- tissue DEVELOPMENTAL- birth to death SYSTEMIC- what we will do..example: skeletal, COMPARATIVE- cat to a human

3 ANATOMICAL POSITION – standing erect with face forward, arms at the side, palms forward

4 Location,position,direction…
ANTERIOR or VENTRAL – front or in front of POSTERIOR or DORSAL – back or in back of

5 CRANIAL – refers to the head of the body
CAUDAL – means tail end SUPERIOR – upper or above something INFERIOR – lower or below something

6 MEDIAL – toward the middle
LATERAL – toward the side of the body PROXIMAL – toward the point of attachment to the body or the trunk of the body DISTAL – away from the point of attachment to the body

7 SUPERFICIAL (EXTERNAL) – near the surface or outside the body
DEEP (INTERNAL) – inside the body

8 *** good for planes, direction.  All systems

11 Body Planes and Sections
PLANES – imaginary anatomical dividing planes SECTION – cut made through the body in the direction of a certain plane

12 Body Planes and Sections
SAGITTAL PLANE – divides the body into right and left parts

– vertical cut at right angles to saggital plane, divides the body into anterior and posterior portions (cheese)

14 TRANSVERSE PLANE – cross-section, a horizontal cut that divides the body into upper and lower parts (bread…?BLT)

15 Midsagital …also known as the midline, divides the body from top to bottom into equal left and right halves.

16 Video planes

32 Bell… Choose (3) three word roots related to a part of the body. Add different prefixes and/ or suffixes to the word root to create at least three different terms. You should end up with 9 new words!

33 Bellringer/payday Using the papers on your desks
Without you book Use a pencil to….Complete the labeling using directions, regions. cavities. After you have completed both sides get your books out and make any corrections!

34 Bell… Make sure Workbook page 3 C 1-5 and
Page 6 E matching is complete Put your first and last name on this assignment and turn in (slide in blue binder) NEW assignment: Complete “what doesn’t belong”

35 Bell Complete ‘Apply Practice to Theory’, at the end of chapter one. Complete 1-3

36 You be the surgeon Open your rice crispy treat
Tear apart into three pieces Create a snowman-type person Determine which side is Dorsal vs. ventral…put on his/her M&M belly button and eyes…what cavity was the eye? What region belly button? Show me anterior/ventral Make sure : Anatomical Position

37 You be the surgeon, cont. Male a cut along the frontal plane
Make a vertical cut, at right angles to the sagital plane ½ way in to the body Cut across the transverse plane Make an incision in the hypo gastric region Make an incision in the RLQ (appendectomy) Perform a thoracotomy

38 Suffixes Class devides in ½
Write meaning on one side and the suffix on the other (thru malacia) Spread suffix side up one table We will stand in line and race to put on table/board Quiz to follow!

39 Bell Look around, your seat may have changed!
Quietly study you list of suffixes Quiz in a moment

40 Life Functions …are the necessary activities to help living organs grow and function. They include movement, ingestion, digestion, transport, respiration, synthesis, assimilation, growth, secretion, excretion, regulation and reproduction. (see pg 6 table 1.1)

41 What is necessary to keep us alive and functioning?
Tissues Specialized cells grouped according to function, shape, size and structure. When grouped together they form…. Organs Larger and functional units of tissues. When organs are grouped together to perform a function that are known as an Organ System See pg 63

42 Metabolism-the functional activities of cells that result in growth, repair and release of energy. 2 Processes… 2) Catabolism- the breakdown of the breaking down and changing of complex substances into simpler ones with the release of energy and CO2. 1) anabolism- the build up of complex materials from simpler ones, such as food and oxygen.

43 Homeostasis The proper function and maintenance of the body depends upon a number of activities. The body must constantly respond to changes in the environment. The maintenance of such internal environmental conditions is known as_____.

44 Bell Create a Quiz from suffixes a-malacia
>>>>>You choose which type (just remember BE Different…most likely will choose yours)

45 Bell/payday From medical terms packet….
Complete worksheet called Medical Terms Identification

46 Tissues TISSUES – cells grouped because they are similar in shape, size, structure, and function

47 EPITHELIAL TISSUE – protects the body by covering internal and external surfaces, and produces secretion Epithelial tissue comprises an uninterrupted layer of cells.  Epithelium covers nearly all external and internal body surfaces. p56 Squamous-flat irreg. Lines… Cuboidal-cubed shape. Lines… columnar cells (A) -elongated. Lines… Glandular-Secretions such as milk hormones, dig. juices

48 CONNECTIVE TISSUE – supports and connects organs and tissue
These tissues are responsible for cushioning, supporting and maintaining form within the body and include adipose, cartilage, bone, tendons and ligaments Vascular

49 ADIPOSE TISSUE – type of connective tissue that stores fat cells

50 connective tissue LIGAMENTS – strong, flexible bands of connective tissue that hold bones firmly together at the joints TENDONS – white bands of connective tissue attaching skeletal muscle to bone CARTILAGE – firm, flexible support of the embryonic skeleton and part of the adult skeleton BONE- skeleton. Supports tissues and organs. VSCULAR-liquids blood tissue (Example RBC)

51 MUSCLE TISSUE – has the ability to contract and move the body
Muscle is an excitable tissue, meaning that it can be stimulated mechanically, chemically or electrically to produce an action potential Smooth, skeletal ,or cardiac Vol vs. Invol

52 NERVOUS TISSUE – cells that react to stimuli and conduct an impulse
Neurons are highly specialized cells that generate and transmit electrical impulses (action potentials) permitting rapid communication between distant areas of the body.


54 Tissues Muscle Smooth Cardiac Skeletal Connective
Hard – Cartilage, Bones Soft – Adipose, Ligaments, Tendons Epithelial Skin Membranes – Mucous and Serous Nerve Neuron

55 Getting Complicated Complete each answer
Hint: 1-9 look on pages (# 2 is sperm) Hint: look at chart on page 64.

56 Bell/Payday… List the four types of Tissues
Give one example of each type

57 Bell List the 4 types of tissue Using NC Health Careers book
Explore Cytologist Technologist/Technician OR Histologic Technologist Brief description of what they do How much education? Technologist Technician -Where can you go to school? Who provides your certification? -What is the work environment? How much $ can you make?

58 MEMBRANES – formed by putting two thin layers of tissue together, cells may secrete a fluid Membranes are vital  because they separate the cell from the outside world.  They also separate compartments inside the cell to protect important processes and events.

59 Epithelial Membranes: 2 classes
MUCOUS MEMBRANES– lines digestive, respiratory, reproductive and urinary systems – produces mucous to lubricate and protect the lining They line various body cavities that are exposed to the external environment and internal organs. Serous– double-walled membrane - produces a watery fluid (Serous fluid) lines closed body cavities the outer part of the membrane that lines the cavity is the PARIETAL membrane the part that covers the organs is the VISCERAL membrane. Pleural, Pericardial, Peritoneal

60 PERICARDIAL MEMBRANE – lines the heart cavity and protects the heart
Serous Membranes… PLEURAL MEMBRANE – lines thoracic or chest cavity and protects the lungs PERICARDIAL MEMBRANE – lines the heart cavity and protects the heart PERITONEAL MEMBRANE – lines the abdominal cavity and protects abdominal organs

61 Connective Membranes Are made of two layers of connective tissue. Synovial membrane-Lines the joint cavity and prevents friction in joints.

62 Primary takes place in clean wound where infection is not present.
Tissue Repair! Repair of damaged tissue occurs continually. Two types Primary takes place in clean wound where infection is not present. Secondary larger and deeper wounds. Takes place by granulation. Cicatrix –Scar tissue
