pig lab exam Flashcards
diaphram
dome-shaped muscle which separates the thoracic cavity from the abdominal cavity
The muscles between the ribs caused the chest to expand and contract, changing pressure in the chest and lungs, thus facilitating movement for air in and out of the lungs
umbilical vein
Blood vessels within the umbilical cord function by carrying oxygenated nutrient blood from the placenta to the fetus
liver
The large brown organ appears to occupy most of the abdominal copy.
The function of the liver is the production of bile, a substance that emulsifies (break down) fat
small intestine
It is loosely coiled and held up by mesteries
The function is to complete the digestion of food and absorb the resulting nutrients.
stomach
Large muscular organ lined dorsal to the liver
function helps break down food into small particles of carbohydrates, protein, and fats.
spleen
Large reddish organ lying along the greater curvature of the stomach
Functions to destroys, recycles and synthesizes red blood cells
pancreas
Mass of soft glandular tissue in the meter between the duodenum and the end of the stomach
function 1 endocrine gland, producing hormones like insulin and glucagon to regulate blood sugar, and function 2 exocrine gland, secreting digestive enzymes into the small intestine to aid in food breakdown
colon/large intestine
Compactly coiled on the left side posterior to the stomach.
The function of the large intestine is the absorption of water and minerals from the liquefied chyme that enters it.
umbilical arteries
Fetal blood 2 vessels that carry deoxygenated blood from the fetus to the placenta
urinary bladder
Hollow muscular organ that destroys urine
Function is to hold your urine produced by kidneys until it is through the urethra
umbilical cord
Structure connecting feeds to the mother’s placenta function, delivering oxygen and nutrients while removing waste products
rectum
Regulates egestion of undigested food (feces) from the body
cecum
A blind pouch at the junction of the ileum and the colon
Functions in fiber digestion
Thyroid gland
a small gland that lies directly on top of the trachea
function produces thyroid hormone and also regulates cellular metabolism and calcium levels.
Larynx
a large hollow structure located at the anterior end of the trachea
Function: passageway for air during respiration
Trachea
a tubular organ formed by cartilage rings that carries air from the larynx
the main airway, making the passage of air between the larynx (voice box) and the lungs, enabling breathing.
Dorsal
Toward the back
Ventral
Toward the belly
Posterior
Toward the tail or behind end
Frontal plane
Runs horizontal to divide the specimen into dorsal and ventral parts
Transverse plane
Went from dorsal to ventral and lies at right angles to the longitude length axis
anterior
Toward the head
Lateral
Toward the side
Medial
Toward the midline
Distal
Farthest from a point of reference
Proximal
Nearest point of reference
Who would carry oxygen-rich blood?
Umbilical vein
Who would carry oxygen poor blood?
Umbilical artery
Who would carry blood high in nutrients?
Umbilical vein
Who would carry blood high in metabolic wastes?
Umbilical veins
What is the function of the cardiac and pyloric sphincters?
The function of the cardiac sphincter is to prevent the backflow of stomach contents, including acid and digestive enzymes, into the esophagus.
pyloric sphincters regulate the digestion process by ensuring that food is properly mixed with gastric juices in the stomach before it is released into the duodenum
ribs
function to protect organs in the chest cavity
duodenum
The first part of the small intestine
the function helps to digest food further, coming from the stomach
Mesenteries
The mesentery is a fold of membrane that attaches the intestine to the wall around the stomach area and holds it in place
Gall bladder
Function store and release bile.
Bile is fluid they break down fats
kidney
filter waste and excess water from the blood, producing urine, and to regulate blood salt and water levels.
heart
the organ that pumps blood throughout the body
