HUMAN ANATOMY AND PHYSIOLOGY
EVALUATED QUESTIONS AND
ANSWERS


There are two main "branches" of Human biology: -
k k k k k k k k


kCORRECT ANSWER- k


1) Anatomy this deals with the structure (morphology-
k k k k k k k k


shape) of the body and its parts, in other words, what
k k k k k k k k k k k


things are called and what they look like.
k k k k k k k




2) Physiology this studies the function of these parts or
k k k k k k k k k k


asks the question, "how do they work"? What is their
k k k k k k k k k k


job?

Human Biology: Structure and Function - CORRECT ANSWER-
k k k k k k k


In Human Biology the STRUCTURE of something is often very cl
k k k k k k k k k k


osely related to its FUNCTION in the human body -
k k k k k k k k k


kFor example Nerve cells are very long in structure because their f
k k k k k k k k k k k


unction is to carry electrical signals from one area of the body to a
k k k k k k k k k k k k k


nother - they are rather like long electrical cables.

The human body is the sum of its parts and these parts can be stu

Cells - CORRECT ANSWER-

CELLS are the smallest basic living unit in your body.

, Tissue - CORRECT ANSWER- k k k


2. TISSUE : A tissue in biology is defined as: many cells of the SA
k k k k k k k k k k k k k k


ME TYPE that are joined together to do an important function.

4 Types of Tissue to Learn - CORRECT ANSWER-
k k k k k k k k


1. EPITHELIAL TISSUE -
k k k


This tissue makes outer and inner coverings of the body -
k k k k k k k k k k k


for example skin cells and the cells that line your airways.
k k k k k k k k k k k k


2. CONNECTIVE TISSUE -
k k k


This holds and supports and joins other tissues together -
k k k k k k k k k k


bone, cartilage and blood are examples to learn.
k k k k k k k k


3. NERVOUS TISSUE -
k k k


this tissue is special in that it can transmit electrical signals (calle
k k k k k k k k k k k k


d "impulses") around the body. These electrical signals "run" the
k k k k k k k k k k


muscles and many other organs. This happens through NEURO
k k k k k k k k


NS
4. MUSCLE TISSUE - there are * two types of muscle tissue:
k k k k k k k k k k k k


*Voluntary (muscles that you can control -
k k k k k k k


sometimes referred to as SKELETAL muscle because these mu
k k k k k k k k k


scles move your skeleton) And *Involuntary ( muscles that you ha
k k k k k k k k k k


ve no control over -
k k k k


the involuntary muscle tissue is further broken down into CARDI
k k k k k k k k k k


AC (heart muscle) and SMOOTH muscle (muscle that works to ru
k k k k k k k k k k


n your digestive system

Organ - CORRECT ANSWER-3. ORGAN: Defined as -
k k k k k k k


kTwo or more different tissue
k k k k k


types joined together to do an important function
k k k k k k k


— Skin, Heart, liver, kidneys, lungs for example
k k k k k k k




Organ System - CORRECT ANSWER- k k k k


Organ system: Defined as - k k k k


when a 2 or more organs function together to do an important fun

ction:
Example: cardiovascular system, digestive system, nervous syst
