Background:

Anatomy is the science concerned with the shape, structure and the relationship of parts of organisms.

It includes human anatomy, zootomy and phytology. It is divided into macroscopic anatomy and

microscopic anatomy. Physiology is the biological study of the functions of living organisms and their

parts.

The human body contains 11 different systems, which are: The circulatory system that transports

oxygen trough the blood inside the body. The digestive system, which is made up of organs, that break

up food, into energy, vitamins, proteins, minerals etc. The endocrine system, which is made up of

glands, those produce the bodies hormones. The immune system, which is the system of defense our

body has to fight viruses and diseases. Very similar to the immune system, the lymphatic system is also

another type of defense that our body has. The muscular system works with the skeletal system, to

control movement of the body. The nervous system is made up of the brain, the spinal cord, and nerves.

One of the most important systems in the body, the nervous system is your body's control system. The

reproductive system, that allows us to have kids. The respiratory system brings air into the body and

removes carbon dioxide. It includes the nose, trachea, and lungs. The skeletal system is made up of

bones, ligaments and tendons. It shapes the body and protects organs. The skeletal system works with

the muscular system to help the body move. And finally, the excretory system, which gets rid of the

waste our body doesnt need after digesting the food.

An ecosystem is the environment in which an organism lives. An ecosystem involves everything from

location, resources, food, space, predators etc. Ecology is the study of ecosystems. An ecologist usually

investigates and records data concerning en ecosystem or many at the same time. Ecology focuses on

the relationship and behavior between different species living in the same ecosystem. These two words

relate to one another because it is proven that for perfect balance it is needed for ecosystems to be in

equilibrium. This means that if one single species in an ecosystem where to disappear the whole thing

goes bad because the balance is broken.

Purpose:

1) The purpose of the first section is to take everyones blood pressure to compare different levelsof blood pressure and finally average all of them.

2) The second section of the lab is to evaluate a single person from the group and determine thepersons fitness level after the completion of several tests.

Hypothesis:

Materials and Methods:

Stethoscope Sphygmomanometer Chair Timer

Part 1:

1.You begin by inflating the cuff. Once the pressure in the cuff is above the subject's systolic

pressure (140 in this example), blood cannot flow below the cuff. You will hear no sound in the

brachial artery when you listen with the stethoscope. (1)

2. As you release the pressure valve and slowly deflate the cuff, blood begins to flow through the

artery. (1)

3. When the pressure in the cuff is between the systolic and diastolic pressure, you can hear atapping sound with each pulse. The first tapping sound you hear indicates that blood has entered

the artery. Record this reading as the systolic pressure. You continue to deflate the cuff until the

tapping sounds cease.(1)

4. The last tapping sound you hear indicates the diastolic pressure. (1)

5. Repeat steps 1-4 for the rest of the members in the group.

Part 2:

Test 1: Change in systolic from reclining to standing

1. Recline for 5 minutes and record blood pressure2. After the 5 minutes stand and record blood pressure again3. Calculate difference of blood pressure when reclining and standing

Test 2: Standing pulse

1. Stand for 5 min and record pulse2. Record data

Test 3: Reclining pulse

1. Recline for 5 minutes and record pulse2. Record data

Test 4: Pulse increase from reclining to standing

1. Recline for 5 minutes2. After 5 minutes record still reclining

3. Stand up and immediately record pulse when standingTest 5:

a) Return of pulse to standing after exercise1. Exercise vigorously for 5 minutes2. After 5 minutes of exercise stop and count the time it takes for your pulse to go back to standing

pulse.

3. Record time in seconds.b) Pulse rate increase immediately after exercise1. Exercise vigorously for 5 minutes2. After 5 minutes of exercise record pulse3. Calculate the difference of standing pulse to pulse after exercise4. Record dataPost testing:

Wait for teacher to give you data on points for the selected person doing the fitness test.

Data and Observations:

Part 1: Blood Pressure Data

Measurement Person 1 Person 2 Person 3 Person 4 average

Diastolic 90 70 90 90 85

Part 2: Fitness Data Table

Test one: change in systolic form

declining to standing

120/130mm change is 10 3 pts.

Test 2: standing pulse 72 beats/min 3pts.

Test 3: reclining pulse 58 beats/min 3pts.

Test 4: pulse increase from

reclining to standing

72-58=24

Test 5: a) return of pulse to

standing after exercise

b) Pulse rate increase

immediately after exercise
