Diaphragm

Wall of muscle at the cranial end of the abdominal cavity just below the rib cage

Separates the abdominal and thoracic cavity

Salivary glands

Secretes amylase (enzyme) which breaks down starches into simple sugars

Pharynx

Where the oral cavity, nasal cavity, esophagus, and trachea all meet

Esophagus

Passes food from the oral cavity to the stomach

Stomach

Secretes acids and enzymes which aids in the process of chemical digestion

Churning aids in mechanical digestion

Pyloric Sphincter

Ring of muscle which controls the passage of food from the stomach to the small intestines

Duodenum

Major site of chemical digestion

Bile located here to break up fats

Pancreas

Secretes digestive enzymes into the duodenum where mechanically digested food is chemically digested

Caecum

Helps digest cellulose into simple sugars that can later be absorbed by the small intestine

Small intestine

Aids in chemical digestion (in the duodenum) and absorption (past the duodenum)

Colon

Water absorbtion

Liver

Storage of excess sugars in the form of glycogen

Mesentaries

The thin membranes supporting blood vessels that carry nutrients absorbed through the small intestine to the liver

External nares

Openings to nasal passages

Trachea

Connects the pharynx to the lungs

Cartilaginous rings

Larynx

Voice box

Intercostal muscles

Muscles located between the ribs

Homeothermic

Maintain a relatively constant body temp due to a higher metabolic rate

Birds and mammals

Heterothermic

Lower metabolic rate caused body temperature to more closely track environmental temperature

Ventricles

Larger chambers, send blood out to the lungs and the body

Atria

Smaller chambers, receive blood returning to the heart from the lungs and the body

Aorta

Large artery that leaves the heart

Leads to 1. iliac arteries 2. mesenteric arteries 3. renal arteries

Renal arteries/veins

Close connection the the kidneys

Spleen

Recycles red blood cells

In abdominal cavity

Vena Cava

Veins that transport de-oxygenated blood from the body to the right atria of the heart

Kidneys

Maintain water balance

Selectively remove waste products and excess salt from the body

Bladder

Connected to the kidneys via two ureters

Testes

Sperm produced here (gonads)

Epididymis

Coiled tube that transports sperm from the testes to the vas deferens

Vas deferens

They extend from each epididymis to the urethra (both tubes join here)

Urethra

Tube which carries urine and semen through the penis

Prostate glands and Seminal versicles (vesicular glands)

Secretes substances that mix with sperm to make semen

Ovaries

Eggs produced here (gonads)

Uteri

Where eggs are fertilized and embryos develop

2 in rats, 1 in humans

Vagina

Where the 2 uteri meet

What systems are involved in obtaining oxygen for cells?

Respiratory

Circulatory

What systems are involved in obtaining building blocks such as amino acids, monosaccharides, etc for cells?

Circulatory

Digestive

What systems are involved in obtaining water for cells?

Circulatory

Urogenital

What systems are involved in getting rid of carbon dioxide?

Respiratory

Circulatory

What systems are involved in getting rid of metabolic waste (i.e. urea)?

Urogenital

Circulatory

What systems are involved in getting rid of extra water?

Urogenital

Circulatory
