Human Body And Pig Dissection

Front 1

Human Torso: The Heart

Back 1

Separated between the systemic and circulatory system, the heart functions to pump oxygen poor blood out through the pulmonary arteries which allows the lungs (which are connected to the pulmonary veins) to pump oxygen rich blood back to the heart.

Front 2

Human Torso: The lungs

Back 2

The lungs function for breathing. There are two lungs and they are located in the upper chest cavity.

Front 3

Human Torso: The Stomach

Back 3

The stomach functions to store food and substances before it hits the small intestine for absorption. The stomach stores, mixes, transports, and breaks down chemicals.

Front 4

Human Torso: The Pancreas

Back 4

The Pancreas functions to produce enzymes and alkaline bicarbonate to offset the acidity of acid chyme. alkaline bicarbonate changes acid chyme into just chyme.

Front 5

Human Torso: Gallbladder

Back 5

The gallbladder functions to store bile. (can have gallstones, some may produce fever)

Front 6

Human Torso: The Diaphragm

Back 6

The Diaphragm functions in helping a mammal breathe. During inhalation the diaphragm contracts which increases the volume of the thoracic cavity. When a person exhales, the diaphragm relaxes which decreases the volume of the thoracic cavity.

Front 7

Human Torso: The spleen

Back 7

The spleen functions to recycle old red blood cells and stores platelets and white blood cells. It also helps fight against certain types of bacteria and meningitis.

Front 8

Human Torso: The trachea

Back 8

The Trachea functions as an airway to the lungs. It starts in the pharynx and goes down the center of the body to the lungs where it branches off into two bronchi- one for each lung.

Front 9

Human Torso: The esophagus

Back 9

The esophagus plays a major role in digestion. The esophagus, a large tube running from the pharynx to the stomach, aids in digestion by passing food and substances using peristalsis down to the stomach.

Front 10

Human Torso: The large intestine

Back 10

The large intestine (or colon) is connected to the small intestine at a t-shaped junction called the ileocecal junction. The purpose of the large intestine is to absorb water. (about 7L daily). As water is reabsorbed in the colon, feces becomes more in tact or compacted.

Front 11

Human Torso: The small intestine

Back 11

The small intestine functions in absorbing nutrients and the breakdown of macromolecules

Front 12

Human Torso: Urinary bladder

Back 12

The urinary bladder is used to store urine from the kidneys to make urination voluntary and infrequent.

Front 13

Human Heart

Back 13

Find: Superior and Inferior vena cava, right atrium, left atrium, right ventricle, left ventricle, pulmonary semi-lunar valve, aortic semi-lunar valve, pulmonary arteries, pulmonary veins, tricuspid valve, mitral valve, septum

Front 14

Human Kidney

Back 14

Find: Renal artery, renal vein, renal pelvis, renal medulla, renal cortex, nephrons, ureter, collecting duct, renal pyramid

Front 15

Female Reproductive Model: Ovaries

Back 15

Function: Egg production and storage; female glands

Front 16

Female Reproductive Model: Oviduct

Back 16

Function: Ducts leading out of the ovaries, egg travels through duct

Front 17

Female Reproductive Model: Fimbriae

Back 17

Function: sweeps the secondary oocyte into the fallopian tube or oviduct

Front 18

Female Reproductive Model: Uterus

Back 18

Function: site where egg implants for development. The lining is the endometrium (shed during menstrual cycle).

Front 19

Female Reproductive Model: Endometrium

Back 19

Function: Helps protect a baby in the womb, gives nutrients. When there is no egg fertilized, this is the menstrual cycle.

Front 20

Female Reproductive Model: Cervix

Back 20

Function: Opening of the uterus

Front 21

Female Reproductive Model: Vagina

Back 21

Function: Birth canal; copulatory organ (any organ involved in sexual reproduction).

Front 22

Female Reproductive Model: Urinary bladder

Back 22

Function: store urine for infrequent urination

Front 23

Female Reproductive Model: Urethra

Back 23

Function: carries urine from the urinary bladder to the outside of the body.

Front 24

Female Reproductive Model: Rectum

Back 24

Function: temporarily storing fecal matter until expelled through the anus

Front 25

Female Reproductive Model: Anus

Back 25

Function: Release of fecal matter

Front 26

Male Reproductive Model: Testis

Back 26

Function: (Male Gonads)- sperm production within seminiferous tubules.

Front 27

Male Reproductive Model: Epididymis

Back 27

Function: sperm maturation

Front 28

Male Reproductive Model: Vas Deferens

Back 28

Function: Duct through which sperm travels out of epididymis

Front 29

Male Reproductive Model: Urinary bladder

Back 29

Function: Store urine to decrease the frequency of urination

Front 30

Male Reproductive Model: Urethra

Back 30

Function: tube connecting and draining urinary AND reproductive systems. (NOT THE SAME IN WOMEN)

Front 31

Male Reproductive Model: Prostate Gland

Back 31

Function: Nourishes sperm, (makes up 25% of secretion)

Front 32

Male Reproductive Model: Seminal vesicles

Back 32

Function: secretions make sperm MOTILE, repress female immunity. (makes up 60% of secretion)

Front 33

Male Reproductive Model : Bulbourethral gland

Back 33

Function: Neutralize pH of urethra. (15% of secretion). makes a safe passageway for sperm.

Front 34

Male Reproductive Model: Penis

Back 34

Function: Organ of Copulation. (scrotum is for temp regulation).
