2/37

Holds prey

Breathing

Tube leading to stomach;Bolus passes

Equalize pressurein inner ear

Tube leadingto the lungs

Aids in grabbing prey


3/37

Digestion

Secretes pancreatic juice,

insulin & glucagon


4/37


5/37

Makes bile(aid indigestion)


6/37

hepatic artery bring nutritional blood to the liver Oxygen and nutrients to the liver

portal vein bring functional blood to the liver blood coming from the digestive tract, which the

hepatocytes function to detoxify.

bile ducts bile flow is opposite blood flow

bile (product of the hepatocytes) emulsify fat in the digestive system

coalesce to form hepatic duct

7a aortic

valve

6a mitral valve3a semilunar/pulmonary valve

5 pulmonary veins


9/37

Heart pumps blood to the different parts of the body

Valves prevent backflow of blood

Spiral valve (frog) prevents mixing of oxygenated anddeoxygenated blood

ARTERY carry oxygenated blood AWAY from the heart; heart to tissues of the body

EXCEPT pulmonary artery carries deoxygenated blood to lungs (foroxygenation & removal of excess CO2)

VEIN carry deoxygenated blood TOWARDS the heart;

All veins carry deoxygenated bloodEXCEPT pulmonary vein

carries oxygenated blood from the lungs tothe heart


10/37

The left ventricle is thicker and more muscular

than the right ventricle because it pumps bloodat a higher pressure.

The left ventricle pumps blood to the entire

body whereas the right ventricle pumps all ofits blood directly to the lungs.


11/37

Vasa vasorum(blood vessels)

Nervi vasorum

In comparison with vein, arteries are

thicker more elastic smaller lumen located deeper in the body same thickness of intima thicker media thinner adventitiaFxn: carry blood away from the heart

In comparison with artery, VEINS are

thinner less elastic larger lumen located superficially same thickness of intima thinner media thicker adventitia fxn: carry blood toward the heart


12/37

1. Tunica intima (innermost)

a.k.a. endothelium (simple squamous epithelium)

only 1 layer2. Tunica media (middle)

Consists of smooth muscle cells

3. Tunica adventitia (outermost)

Consists of connective tissues

Nerve bundles (nervi vasorum) and vessels of thevessels (vasa vasorum) can be located

the blood

5 Penile urethra


20/37

Ovary egg cell formation


21/37

Eggs travel throughthese ducts


22/37

Oogenesis

Formation and maturation of oocytes fromundifferentiated cells in the ovary

Vitelline membrane

Immediate covering of an oocyte

Made up by follicle cells and oocytes Secreted by follicle cells

Function: protects the oocyte

Follicle cells

Nourish the eggs

Secrete estrogen
