    Study Notes

    Chapter VI: Respiratory System

    • The respiratory system connects the nostrils to the lungs, subdivided into upper and lower respiratory tracts.
    • Its primary function is the exchange of oxygen and carbon dioxide in the blood.
    • The tonsils in the pharynx are part of the protective system..
    • Nasal hairs filter out large particles, smaller particles are trapped in the lining mucosa.
    • Phonation (sound production) is caused by vibrating vocal folds.
    • Olfaction (smell) relies on receptors in the nasal lining.
    • Panting helps regulate body temperature through evaporation.
    • The lungs also help control acid-base balance and regulate circulating substances.
    • The external nose is a structure protruding slightly from the face.
    • The philtrum is the groove between the nostrils in the lip.
    • Nostrils are the external openings into the nasal cavity
    • Bony nasal aperture is the immovable part of the nose
    • The nasal cartilages form the movable part of the nose which gives it its appearance.

    Nose - Nasal Cartilage

    • Philtrum is deep in carnivores, and small ruminants, shallow or absent in pigs, oxen, and horses.

    Nasal Cavity

    • The nasal cavity extends from the nostrils to caudal nares.
    • It's divided into halves by a median nasal septum
    • The vestibule is the rostral part inside the nostril.
    • Nasal conchae are bone scrolls lined with mucosa.
    • Meatuses are the passages between the conchae.

    Upper Respiratory System

    • Includes the nasal cavity, pharynx, larynx, trachea, bronchi and lungs.

    Chapter VII: Urinary System

    • The urinary system includes the kidneys, ureters, urinary bladder and urethra.
    • Kidneys filter blood and produce urine.
    • Situated high in the lumbar region, behind the peritoneum.
    • The kidneys are retroperitoneal.
    • Left kidney is more caudal than the right kidney, except in the pig.
    • Perirenal fat surrounds the kidneys and holds them in place.

    Chapter VIII: Reproductive System

    • Ovaries (female gonads) are round or oval.
    • They contain follicles, corpora lutea, connective tissue.
    • The uterine tube runs between the ovary to the tip of the horn.
    • The infundibulum is the expanded end of the uterine.
    • The fimbriae extend to pick up the oocyte during ovulation.
    • The location of the ovaries varies considerably by species.
    • The mare and bitch have paired ovaries, located in the sublumbar region.
    • In cows, ewes, and sows, the ovaries are located in the pelvic inlet area.

    Uterus

    • The uterus is a highly expandable, tubular organ.
    • The cervix is the constricted, caudal part of the uterus connected to the vagina.
    • The uterine body connects the cervix to the horns.
    • Uterine horns extend cranially from the body.
    • The different species of animals have significant variations.

    Vagina - Vestibule - Vulva

    • The vagina runs between the cervix and the vulva.
    • The vestibule is the area connecting the vagina and vulva
    • The vulva is the external opening of the genital tract.
    • The clitoris is a homologous structure to the male penis.
    • The hymen is a poorly developed, vestigial fold.
    • In several species, vestibular glands for lubrication are present.

    Chapter IX: Circulatory System

    • The circulatory system consists of the heart, blood vessels, and lymphatics.
    • It's a major system for nutrient transport and waste elimination.
    • It functions to acquire oxygen, and transport, and distribute throughout the body.
    • There are two major circuits in the human circulatory system, namely the pulmonary and systemic circuits.
    • The pulmonary circuit receives deoxygenated venous blood from the body.
    • Oxygenated blood travels from the lungs to the left side of the heart.
    • Then, the oxygenated blood is distributed to the body from the left side of the heart through the aorta.
    • Fetal circulation differs significantly from adult circulation, containing several shunts to bypass the lungs.

    The Heart

    • The human heart is composed of four chambers, namely two atria, right and left, and two ventricles, right and left.
    • The right side receives deoxygenated blood and pumps it to the lungs.
    • The left side receives oxygenated blood and pumps it to the body.

    Fetal Circulation

    • The umbilical vein delivers oxygenated blood to the fetus.
    • The ductus venosus connects the umbilical vein to the inferior vena cava.
    • The foramen ovale is an opening that helps oxygenated blood bypass the fetal lungs.
    • The ductus arteriosus shunts blood from the pulmonary trunk to the aorta to bypass the non-functional lungs.
